It expires Monday, 2nd October at 0800 GMT. I will post again if I still need help after this time. Thanks in advance if you respond. I am doing things remotely from home and haven't yet physically installed the card hence why I am not able to answer these questions empirically. I have installed the Solaris videopix support SUNWvfc (which only appears to contain vfctool and a couple of .h files) and SUNWvpx (which seems to contain the basic driver), but on beginning to install SUNWvpu/SUNWvpxu I get the following warnings: WARNING: The package "XIL Run Time Environment" is a prerequisite package and should be installed. Allowable instances include (in order of preference:) 1.0,REV=1.0.5 WARNING: The package "XIL English Localization" is a prerequisite package and should be installed.

The bulk of the session will be from an interview team visiting and reporting on each of the exhibits as well as the keynote address. Also, if feasible, a low-bandwidth overhead view of the exhibition hall will begin on the Saturday prior to the exposition itself (not unlike, the "Eyes On Interop" session a while back). ...tad The second annual Internet Fair (http://www.larc.nasa.gov/if2/) is being held at the NASA Langley Research Center's Reid Conference Center, October 23 and October 24 from 9:00 a.m. - 4:30 p.m (US/Eastern). Wolfgang To"lle, the Managing Director for the Virginia Center of Innovative Technology, will give a keynote address from 11:30 a.m. to 12:00 p.m. on October 23. The mission of the Internet Fair is to exchange NASA (http://www.nasa.gov/) and Hampton Roads (http://www.larc.nasa.gov/larc.cgi?+s5#s5) information technology while emphasizing challenges and solutions for the future. The Fair will include exhibits from NASA Langley (http://www.larc.nasa.gov/), local businesses, and universities. These exhibits, which highlight the cost benefits of information technology for NASA and the public, are divided into six focus areas: - NASA - Demonstrated will be projects and efforts where NASA LaRC is integrating WWW and other technologies like GIS and relational databases into its business processes. Detailed information can be found for efforts applicable to BPR, Re-engineering, Corporate-wide IT training, Wide-Area Information Distribution, Institutional Management Systems, and Decision Analysis Tools. - Regional Technology Enterprises - Visit the many technological businesses that are available in the Hampton Roads region ready to share their successes and assist you in meeting your needs for the present and future. - Education - Witness the wealth of schools in the local area that have achieved full Internet access. Come see and hear how teachers, students, and organizations are working together to provide the next generation affordable access to the vast library of information and connectivity capability available via the Internet. - Community Redefinition - Learn how Freenets and other Internet services and tools are reshaping our community to achieve equal access to shared services. Learn how you can share in the modeling and reshaping of our community to meet our future needs. - Entertainment - See how its not just high-tech industries that are using these new technologies it is also the fine arts that are embracing these new ways to enrich our culture. - Media - Hear how our local media is distributing information and combining various forms of media to meet increasing customer needs. For More Info The Fair is sponsored by the NASA Langley World Wide Web team, which is composed of members from throughout NASA Langley.

NASA Langley Internet Facts and Statistics Langley Research Center has been an Agency leader in creating an easy-to-navigate Internet presence for NASA. On July 23, 1993, NASA Langley was the first NASA field center to put up a field center home page. Since then, there have been almost half a million electronic visitors to Langley. NASA Langley has distributed over 30,000 reports distributed via the Langley Technical Report Server (http://techreports.larc.nasa.gov/ltrs/ltrs.html), and NASA has distributed over 60,000 NASA reports via the NASA Technical Report Server (http://techreports.larc.nasa.gov/cgi-bin/NTRS), which was developed by Langley. In addition, over 500 computer software packages distributed via the Langley Software Server (http://www.larc.nasa.gov/LSS/).

The objective is threefold: [1] to test the hybrid configu- rations of various technologies, [2] to offer the participants a stage for meeting at a distance and gaining confidence in using novel means of communication -- an opportunity for hands-on "collaborative experiential learning" about the technologies and their applications, and [3] to gain knowledge of the different participants countries regulatory environment that have thus far made sophisticated electronic distance education (EDE) inaccessible to them. Many less developed countries are without good analog voice-grade telephone networks, and hence without Internet access. Subsequently, use of electronic distance education, though an economic advantage to them, is not realized. Therefore, the purposes of the GLH are [1] to have participants view and compare various advanced (yet affordable) delivery systems with technical and economical pros and cons, [2] to stimulate educators and decision-makers in the less developed countries to foster global electronic distance education. These demonstrations have helped build a network of leaders in the global electronic distance education movement. PARTICIPATION: The computer screen will be uplinked for worldwide broadcast. If you have a satellite downlink facility and our satellite foot-prints cover your area, you can receive our satellite signal. You can also participate with your personal computer and/or workstation which are directly connected to TCP/IP oriented Internet without use of satellite nor dish antenna. Other than participation fee (*), all participants have to be responsible for the costs of (1) down/uplinking from/to satellites; (2) telephone call to a videoconference center at the Ohio University for Q&A; and (3) sending fax to the center for backstage coordination. (*: Under regulation, fee of participants with INTELSAT satellite will be waved, but they are encouraged to donate to GLOSAS/USA.) Please contact Takeshi Utsumi for registration form. Registrants will then receive instructions for participation. ********************************************************************** * Takeshi Utsumi, Ph.D. * * Laureate of Lord Perry Award for Excellence in Distance Education * * Founder of CAADE * * (Consortium for Affordable and Accessible Distance Education) * * President, Global University in the U.S.A.

Use of the Multicast Backbone (MBone) continues to grow since our GLH last year. Over 1900 subnets are currently MBone-capable. Technical improvements also continue. A new video tool named 'vic' by Steve Mccanne and Van Jacobson of Lawrence Berkeley Laboratories can deliver improved frame rate to viewers using H261 encoding. vic is available at ftp://ftp.ee.lbl.gov/conferencing/vic/vic-*.tar.Z This year we will multicast using vic's H261 encoding to demonstrate high-quality live video, free software tools, and a scalable approach that is superior to commercial unicast products. vic uses version 2 of the Real-time Transport Protocol (RTP) being developed by the Internet Engineering Task Force (IETF). During this year's GLH session we will examine recent uses of the MBone for distance learning. First we will show how Dr. Richard Hamming's course "Learning to Learn: Future of Science and Engineering" was multicast >from Monterey three times a week for three months with world-wide scope. Then we will show how we combined standard video gear, an inexpensive Indy workstation, wireless microphones and a wireless bridge to create a mobile Internet-based MBone station. This rig became "MBone Unplugged" as we brought mobile coverage of Interactive Communities exhibits and K-12 sessions at the ACM SIGGRAPH 95 computer graphics conference in Los Angeles California.

As you may be remember The Association for International Education is realizing pilot project in distance education with State University of New York. Two weeks ago four our students advocated successfuly their thesises by means of well-known videoconference MBONE. We used SUN Sparc Station 5, Solaris 2.3, SUN camera model X485A and SUN video card model X1085A. Video camera and video card were loaned to us by SUNY. We are very grateful to Dean Edward Tezak. Our colleague from SUNY (Professor Scott Spetka) helped us to install IP multicast protocols in our Solaris kernel and got an mrouted going along with the other software. We used own on-line 64 Kbps channel which was constructed by Golden Line (Russian-Canada join stock enterprise) into Relcom (it is Russian provider of e-mail), but in live we used only about 32 Kbps, because there is the thin channel anywhere abroad. During of thesis defence we used the Xerox nv (network video) program for sending video, LBL vat (visual audio tool) for audio, LBL wb (whiteboard) for postscript and text, and LBL sd (session directory) for connection management. Frankly speaking vat works very poor, we could not understand each other and therefore on the both ends we started to use a speaker telephones hooked up so everyone could hear the questions from SUNY faculty and answers of students. We received and sent rather good color pictures with size of quarter computer screen, simultaneously were demonstrated slides of student's thesises on the whiteboard in postscript form. We provided one defence every day during about two hours from 6 pm Moscow time: half hour - technical connection, 40 minutes the report, half hour the questions/answers, than final decision. As the results of our experiment I can say that it is possible to use MBONE in distance education purposes on a level with CU-SeeMe. Our SUNY colleagues and all of us were fully satisfied with this experiment. Dean Edward Tezak wrote: "I would like to congratulate everyone on our historic achievement today. I believe that the defense went very well". Also about the Moscow-SUNY thesises defence by means of videoconference and others Assosiation activities you could read in Russian central newspaper "Izvestia" from 20 September on the first page. I hope to use this technology in Australian-Russian Distance Education Project that has already started from 4 September. I manage of this Pilot Project. Our distance education group includes 14 students and they had begun to pass first assignments on this week. <> <> <> <> <> Sincerely Yours, Aleksey Skuratov Coordinator of Australian-Russian Pilot Project Head of the Department "Videoconference and Satellite Telecommunication" of Information Systems Research Institute of Russia Fax: +7(095)288-1861 +7(095)232-3654 E-mail: Aleksey@Skuratov.isrir.msk.su ********************************************************************** * Takeshi Utsumi, Ph.D. * * Laureate of Lord Perry Award for Excellence in Distance Education * * Founder of CAADE * * (Consortium for Affordable and Accessible Distance Education) * * President, Global University in the U.S.A.

At the same time, the exposure to various applications will help in making CG more directly relevant. One way to encourage such interactions is by organizing special workshops and meetings that involve Computational Geometers and members of other communities. One of the first efforts in bringing together researchers in both applied fields and Computational Geometry was the NSF Workshop on Manufacturing and Computational Geometry. This workshop was held at the Courant Institute of Mathematical Sciences, New York University, on April 1-2, 1994. The meeting agenda included discussion on current trends in the two communities, identification of mutual interests and proposal for future joint activities. The workshop signifies the first step in steering the Computational Geometers' attention towards manufacturing applications. In January 1995, International Computational Geometry Software Workshop was held at the Geometry Center at the University of Minnesota to discuss the current state of the art in geometric software and its applications. Although both workshops have generated new insights in making CG more applicable to other areas, the nature of both meetings was by invitation only. This limits the number of participants and those who may benefit from the discussions. In addition, the cultivation of a "geometric-engineering" subcommunity that understands both the theory and applications is slow. Continuing efforts with increasing participation will be needed to realize this new culture of "geometric-engineering". The 1996 Symposium on Computational Geometry will be held from May 23 to 26, in conjunction with the 2nd Federated Computing Research Conferences (FCRC) in Philadelphia. The present workshop will be held immediately following the ACM Symposium on Computational Geometry. Objectives and Scope -------------------- The objectives of this workshop include the following: (1) To review the state-of-art research in computational geometry and its related application areas (modeling, robotics, computer graphics, manufacturing, vision, synthetic environments, CAD/CAM, GIS). To demonstrate current capabilities and/or achievements in research worldwide. (2) To highlight critical issues that remain unsolved in technology transfer from computational geometry to other more applied fields. To identify areas of research interests where theory can advance the state of technology and/or where the application can provide the impetus for basic scientific development. (3) To create a forum for discussion on how to address these critical issues with a constructive evaluation on research focus towards a "multidisciplinary" coordinated effort for collaboration. This should lead to more effective technology transfer from computational geometry, as well as better advancement in the applied technology. (4) To provide insights for future research directions and potential follow-up applications workshops. Program ------- The workshop program will consist of invited presentations given by renowned researchers in manufacturing, vision, robotics, graphics, GIS and computational geometry. In addition there will be contributed presentations and panel sessions on geometry software, geometric applications and funding directions. We expect a significant participation from various funding agencies, industry, research and government labs in addition to researchers >from academia. Call for Participation ------------------------ We invite submissions of abstracts for contributed presentations to be given at the workshop. We welcome survey of geometric algorithms in other applied fields and their relevance to computational geometry, description of geometric applications, novel techniques in geometric computing, development experiences in applied geometry, critics on the state of arts, and key issues in technology transfer, etc. The submission will be evaluated on its scientific merits, technical contents, and relevance to the objectives of the workshop.

Authors of the best papers presented at this conference will be invited to submit full papers for consideration as articles in a special issue of PRESENCE after a further review process. FIVE is supported by the European Commission ESPRIT programme. The conference is also sponsored by IFIP Working Group 5.10. The FIVE Working Group was started in May 1995, with European Union ESPRIT funding. Its mission is to study and provide an integrated framework across a number of domains at the foundation of Immersive Virtual Environments (IVEs). The Conference has three major aims: first is to advance fundamental scientific research at foundations of IVEs; second, to bring the research of the Working Group to a wider audience; third, to invite researchers from other institutes to present their work, to open a dialogue leading to future collaborative exchanges. The conference has keynote contributions from the FIVE group members and also an invited keynote talk from Steven Ellis, of NASA Ames Research Centre. The Conference is truly international, with papers from the following countries: France, Germany, Italy, Netherlands, Switzerland, UK, USA The conference will have an intensive but informal workshop style atmosphere, and for this reason there will be a maximum of 50 participants. Places will be available strictly according to order of receipt of applications.

Multimedia '95 will take place November 5-9 in San Francisco, with the technical sessions scheduled for Tuesday November 7 through Thursday November 9. At this point, we have not made a final determination of which sessions we want to transmit. We certainly want to send the opening and closing plenaries: date time(PST) time(GMT) session/speaker(s) --------- ----------- ----------- -------------------- 07 Nov 95 08:45-10:30 16:00-19:00 Opening/Cliff Stoll 09 Nov 95 15:30-17:15 15:00-02:00 Closing/Carol Peters + panel (GMT times rounded to even hours, per "MBone Global Agenda" instructions.) I have tried repeatedly to book these slots via the official Web page form, but it fails every time due to connection timeout. We also hope to transmit additional sessions from the conference that the MM95 program committee deems to be of most interest to the Internet/MBONE community. For this reason, I would like to tentatively reserve the following larger blocks of time: date time(PST) time(GMT) --------- ----------- ----------- 07 Nov 95 08:45-17:30 16:00-02:00 08 Nov 95 09:00-17:30 15:00-02:00 09 Nov 95 09:00-17:15 15:00-02:00 If anyone has a conflicting event that they wish to send, please contact me at your earliest convenience so that we can resolve the scheduling issues. I will work with the MM95 program committee to refine the above reservation as quickly as possible, but I wanted to get it on record now to detect any potential conflicts.

Wales is a country within the United Kingdom. We don't expect to broadcast the event, but we DO expect to be present in the demonstration areas and we want to provide some real usage demonstration of Mbone style applications, not just the tools themselves. (But folks we are likely to be fed by just a two channel ISDN service with compression as the final link. We have prior experience that shows this can still provide quite a good demonstration though). The current Mbone WWW agenda does not seem to contain much material scheduled for that time as yet (but it is eight weeks or so away). If any of you are aware of any particular things happening that might be relelvant could you please let us know. We do have a couple of ideas of `things to do'. 1/. We thought we might organise a `task' where attendees at the demonstration might all co-operate to help complete the task. This might be some sort of global puzzle or game perhaps? Any ideas? 2/. The other obvious idea is to allow attendees to `ask the remote expert', based on topics raised at the conference. The days have themes. a). Wed A.M. Launch + Government b). Wed P.m. Heatlthcare c). Thursday A.M. Business + Telecentres d). Awards ceremony + Multimedia-futures All times implied above can be considered as Greenwich Mean Time (as we call it in the old world...... p.s. as I type we are still in `summer time' but that will end before the event). All ideas, offers of help etc will be gratefully received. Assuming we have lots of offers (knowing how helpful you ll are ... :-) ) then I guess we organize schedules etc....

I would be very grateful if you could diffuse it according your distribution list. Thank you for your kind attention. Call for Papers WIRELESS NETWORKS JOURNAL Baltzer Science Publishers Special Issue "Exposure Hazards and Health Protection in Personal Communication Services" Scope: The rapid diffusion of electronic and telecommunication equipments and systems emitting electromagnetic waves has brought into focus the problems of electromagnetic pollution of the environment and the possible adverse health effects on human beings. In particular, over the past decade there has been a significant increase in the use of hand-held cellular telephones. Because of the proximity of the transmitting antenna to the user's head, great concerns have arose about the potential risks to human health. The problem has been made even more acute by the impending development of wireless data services and wide-band wireless local area networks. Many national and international standard organizations, governmental bodies, and health authorities have issued or are considering approval of standards, recommendations, or legistative actions to protect the public from excessive exposures. In the meantime, scientists and manufacturers are contemplating new design techniques that may reduce the exposure. The aim of this special issue is to highlight problems which are presently under consideration and to present recent progress in this area of research, with particular emphasis on scientific studies used to define exposure limits. Possible topics include, but are not limited to: Biological effects (in vitro and in vivo): - CW fields - modulated fields Dosimetry: - source characterization - electric and magnetic properties of biological materials - experiments and numerical models Epidemiology Interaction mechanisms: - at subcellular, cellular, single organ, and physiological system level Standards and Safety Issues: - cellular phones - wireless data systems and services - wireless local-area networks - Video Display Units The authors should send 4 copies of their paper to one of the Guest Editors by February 1, 1996.

The mixer is somewhat strange, as you apparently use the same volume control for input gain as for thru gain (i.e. you can't record without also listening, so the potential for feedback while using vat is high), but I think this is fixed in the model that is out now, the GUS MAX. Others reccommend the Pro Audio Spectrum 16, I have no experience with that card. Under FreeBSD, the easiest way to use "vat" is to get "vmix", from ftp.cs.uwm.edu/pub/FreeBSD. "vmix" pretends to be an AudioFile server and lets you use the -U option to vat to let vmix actually talk to the audio device.

Jim Lowe reported having problems with the PAS16 locking up every 30 minutes or so at least that will give you an approximate idea. The plain old gus mixes the input and output. The gus max via the cs4231 codec supports decoupling the input and output however one of the chips in the card has a bug which makes dual dma operations impossible. The GUS MAX 1.8 dual dma features works well however that is the older model . The newer GUS MAX models have the hardware bug which was confirmed by a Gravis hardware engineer. You can still use the GUS MAX for dual dma operations tru the GF1 -- thats the old codec and dsp for the GUS . Why you may still want a GUS MAX? Because via the CS4231 codec you can do 16 bit 44khz recording or playback. For now, the GUS or GUS MAX is our best bet for vat or similar audio tools for the *BSD systems. Hopefully, soon (in a couple of months ) there will be sound cards which fully support dual dma in 16 bit 44khz. Gravis is working on such a new card as well as I believe Creative Labs.

The objective is to provide a timely forum for conversation about H.323 issues and help the process come to completion. We feel that conducting regular dialogue among a wide audience can improve the final quality of the document, should help identify and avoid potential pitfalls, and will increase the likelihood of its ultimate acceptance by the marketplace. These meetings are open to all who can contribute to the process, not just IMTC members. In particular, we seek guidance from router vendors and LAN / Internet protocol experts. (Hence, the cc to rem-conf.) The topic tomorrow (12 Oct) will be the choice of addressing for H.323 clients. Current proposals include: 1) E.164 addresses plus extensions. I.e., follow the PBX model, where each terminal has a unique numeric phone number, or phone number plus extension. 2) IP and IPX (numeric) address 3) Internet named addresses (e.g., bake@pictel.com) Gary Thom (H.323's Editor) will participate in the call. Topics for succeeding audiocalls will be determined as we proceed, but generally would be issues which the document editors have requested comments on.

Steve Casner and I believe that this method should be specified in the profile. My suggestion would be to use the method employed by Kerberos, as, for example, implemented in the libdes-3.0 library. It looks like this for (i=0; i>4)&0x0f); j=((j<<2)&0xcc)|((j>>2)&0x33); j=((j<<1)&0xaa)|((j>>1)&0x55); (*key)[7-(i%8)]^=j; } } set parity compute CBC checksum using this temporary key over the string use result as new key (after setting odd parity) This is specified on p. 73 of RFC 1510, routine string_to_key(). The goal of any such scheme is the randomization of the input ASCII string. Steve, any insight on what vat uses? Any other suggestions? Any solution should allow any 8-bit character and should allow strings of any length. Thanks.

Your suggestion is to use MD5 (thought of that...). Since the random number generator already uses an MD5 routine, that imposes no additional code bloat. Either Kerberos or MD5 sounds fine; no obvious reason to prefer one over the other. I'd go with MD5, since the Kerberos randomization is more ad-hoc and has not been subject to as much scrutiny as MD5 (although, here, randomness, not inversion, is the key property). In any event, your suggestion of restricting keys (or rather pass phrases) to ASCII alphanumerics plus blanks (not tabs) is likely to help key transmission by telephone or fax (one common method you don't mention...). [This is a bit more restrictive than your suggestion of 7-bit ASCII, but avoids the 'what's the name for the ?"...] Henning From rem-conf-request@es.net Thu Oct 12 14:50:39 1995 Received: from tower.lcs.mit.edu by osi-west.es.net with ESnet SMTP (PP); Thu, 12 Oct 1995 11:49:55 -0700 Received: from beantown.lcs.mit.edu by tower.lcs.mit.edu (8.6.12/NSCS-1.0S) id OAA04983; Thu, 12 Oct 1995 14:49:54 -0400 Received: by beantown.lcs.mit.edu (940816.SGI.8.6.9/940406.SGI) id OAA01981; Thu, 12 Oct 1995 14:49:52 -0400 From: rabatin@beantown.lcs.mit.edu (George Rabatin) Message-Id: <199510121849.OAA01981@beantown.lcs.mit.edu> Subject: MBONE Reservation request: 12-14 DEC 95 To: rem-conf@es.net, rabatin@beantown.lcs.mit.edu (George Rabatin) Date: Thu, 12 Oct 1995 14:49:52 -0400 (EDT) X-Mailer: ELM [version 2.4 PL24] Content-Type: text Content-Length: 1312 The MIT Laboratory for Computer Science is planning an Mbone presentation of selected sessions of the Fourth International World Wide Web Conference, "The Web Revolution", on Dec. 12th, 13th, and 14th, 1995.

Steve Casner and I believe that this method should be specified in the profile. My suggestion would be to use the method employed by Kerberos, as, for example, implemented in the libdes-3.0 library. It looks like this for (i=0; i>4)&0x0f); j=((j<<2)&0xcc)|((j>>2)&0x33); j=((j<<1)&0xaa)|((j>>1)&0x55); (*key)[7-(i%8)]^=j; } } set parity compute CBC checksum using this temporary key over the string use result as new key (after setting odd parity) This is specified on p. 73 of RFC 1510, routine string_to_key(). The goal of any such scheme is the randomization of the input ASCII string. Steve, any insight on what vat uses? Any other suggestions? Any solution should allow any 8-bit character and should allow strings of any length. Thanks.

Your suggestion is to use MD5 (thought of that...). Since the random number generator already uses an MD5 routine, that imposes no additional code bloat. Either Kerberos or MD5 sounds fine; no obvious reason to prefer one over the other. I'd go with MD5, since the Kerberos randomization is more ad-hoc and has not been subject to as much scrutiny as MD5 (although, here, randomness, not inversion, is the key property). In any event, your suggestion of restricting keys (or rather pass phrases) to ASCII alphanumerics plus blanks (not tabs) is likely to help key transmission by telephone or fax (one common method you don't mention...).

This is one reason why a space becomes %20 in > a URL. Transcribability is a fun requirement! My current wording is as below. (Padding is done by MD5.) The length requirements are to avoid the problem that some application requires, say, 16 bytes minimum length, but some other less, thus not allowing interoperability. This is drawn from the Skey draft. As defined below, the string should be transcribable, pronouncable by phone [thus, no case] and allow use of pass phrases. Comma and period were omitted since they tend to look alike on faxes. If anybody feels strongly about it, we can a few punctuation characters like / and ?. This does not address the method specification, which could be done in any number of user interface ways (button, scroll list, etc.). However, the format would interoperate with Mark's suggestion. (Currently, only single DES is specified anyway.) I'd suggest leaving any additional encryption methods to a later standardization step, to avoid arguments which of the other candidates (beyond DES derivatives) are appropriate. \item[String-to-key mapping:] A user-provided string (``pass phrase'') is hashed with the MD5 algorithm to a 16-octet digest. The digest is folded into a 56-bit DES key by exclusive or-ing the first with the eighth, the second with the ninth, etc., octet of the digest and setting the most significant bit of each octet to its odd parity. Keys should be restricted to ASCII letters, digits, hyphen, and white space. Case is ignored; one or more contiguous white space characters (ASCII space, formfeed, newline, carriage return, tab, vertical tab) are mapped to a single space (ASCII 0x20). Leading and trailing white space is removed. A minimum length of 16 characters should be enforced by the application, while applications must allow up to 256 characters of input.

Thus, providing only seven full bytes may not work without hacking up the DES library. Any experiences with what's out there? libdes-3.0 uses eight bytes with parity, so does SGI's and HP's encrypt function. Same for /usr/include/des/des.h on Solaris (for the DES hardware and software implementation). So does the DES code in Schneier's Applied Cryptography, p. 468.

There was a problem when grabbing both odd and even fields in non-interleaved mode, where pairs of odd/even fields were dropped. This has been fixed. * #264040 - Videod's VINO SW YUV decimation misorders pixels, looks bad. This was noticeable when decimating the YUV (YCrCb) video signal down to 1/4 size for use by applications such as InPerson.

Henning, The problems of mapping a string to a 56-bit DES key and of converting that 56-bit key to a format suitable for a given DES implementation are completely independent. We should not standardize the latter. It is easy enough to insert parity bits, if necessary, before calling a library routine. No need to "hack up" the library itself. I do not see the need to be DES specific. All we need to standardize is a good method for obtaining a key from a string. Mark's suggestion -- to take the first N bits of the MD5 hash -- works for any encryption scheme with keys <= 128 bits (and doesn't depend on parity and what not).

In the first category are: - white-space collapsing: I agree this is a good move, based on experience with vat. There was a mistake one could easily make that would result in a space at the start of the key. - I'm not sure about case insensitivity. Many people like to put capital letters in passwords now; granted, that's largely to get around the limitations of 8 characters. If the string is made case insensitive, then just saying "case is ignored" is not sufficient. The spec must say something like "upper case letters are folded to lower case". Considerations mentioned which fall into the latter category are: - Minimizing the use of punctuation characters, especially comma and period which are hard to distinguish by fax. - If the algorithm is case sensitive, restricting to all lower case, (it's easy to say "all lower case" when communicating by phone, and common practice when communicating filenames, etc.). - For an international communication, restricting to US-ASCII letters and digits. Why should an all Japanese group using a pass phrase distributed in written form have to constrain the pass phrase to the "American English" character set? Indeed, why drop those Umlauts or give up Hebrew or Chinese when they are appropriate for the context? Why not allow "the UTF-2 encoding specified in Annex F of ISO standard 10646" as for SDES strings in the RTP spec? Constraints on which characters should be used fall into the second category above. Are there any whitespace characters in the extended sets? Is case folding well defined for the extended sets? This is one reason I'm unsure about case insensitivity; it might be best to allow both cases to be used and leave case considerations in the second category. > This does not address the method specification, which could be done in > any number of user interface ways (button, scroll list, > etc.). However, the format would interoperate with Mark's > suggestion. (Currently, only single DES is specified anyway.) I like Mark's "DES1/" suggestion because it keeps the whole key specification in one place. It doesn't require saying "select the DES1 algorithm and specify key foobar". An experienced user could click a button and then type in only the key portion if desired, but the UI should accept the prefix also. > I'd suggest leaving any additional encryption methods to a later > standardization step, to avoid arguments which of the other candidates > (beyond DES derivatives) are appropriate. I can go along with this, matching the RTP spec's inclusion of single DES CBC as the default and leaving others to further specifications. I've seen how sensitivity to little things can cause large discussions and long delays. Our main concern at this point is covering the interoperability baseline. But I don't think that precludes specifying the algorithm selection method with just one keyword at this point. -- Steve From rem-conf-request@es.net Fri Oct 13 18:24:13 1995 Received: from atc.boeing.com by osi-west.es.net with ESnet SMTP (PP); Fri, 13 Oct 1995 15:23:41 -0700 Received: by atc.boeing.com (5.65/splinter.boeing.com) id AA22917; Fri, 13 Oct 1995 15:26:43 -0700 Date: Fri, 13 Oct 1995 15:26:43 -0700 From: ericf@atc.boeing.com (Eric Fleischman) Message-Id: <9510132226.AA22917@atc.boeing.com> To: rem-conf@es.net Subject: Local Class D Addresses A Question about "Local" group addresses Dear MBONE community, (cc: CIDR mailing list) Several of my coworkers and I have been discussing our plans (dreams) to eventually deploy production-ready application services relying upon multicast technology. When we began to consider some of the scheduling and capacity issues involved with these types of services we quickly became concerned about collisions between internally used group IP addresses and externally used group IP addresses. That is, let's say we had scheduled event X to use a group address Y at a given time and a public Internet event also coincidentally decided to use group address Y at an overlapping time. Since our internal multicast network would be Internet connected, this implied to us that there would be collisions between the two sessions even though our TTL broadcast value would be very low. In our minds, such collisions would be a Very Bad Thing and would signify that the technology is not viable for production environments. In our discussions we could well imagine "race conditions" to occur for all group address allocation approaches except for approaches which segmented the Class D address space into "public" (Internet-wide) and "local" (non-unique) domains. This implies to us the need to subdivide the Class D space to diminish the possibility of a public venue interfering with a private "event" -- and to provide additional assurance that the private session would not "leak out" into public (e.g., all local ranges could be filtered at the firewall). Since we are novices in this type of consideration, I am wondering whether a more viable solution to this problem has been proposed? If so, I would be grateful to know what it was. Also, if no solution currently exists, I would be appreciative for feedback concerning our idea to divide the Class D space into public and local address ranges.

This version of vic conforms to the final (RTP-7) Internet Draft for the IETF AVT Real Time Transport protocol. It also conforms to the July '95 Internet Draft for the H.261 payload specification. NOTE: Because there were significant RTP and RTP/H.261 protocol changes between vic 2.6 and vic 2.7, ** VIC 2.7 IS NOT BACKWARDS COMPATIBLE WITH VIC 2.6 **. We regret this but changes in the low-level protocol standard make it unavoidable. Vic 2.7 is still compatible with nv and ivs and will interoperate with v2.6 in either nv or ivs compatibility mode. 2.7 adds support for several new video capture devices (VigraPix, SlicVideo, Parallax, SGI Cosmo Compress, IBM RS-6000 Ultimedia -- thanks to the help of numerous contributors). It also has new support for analog video output on machines that support it (DEC J300, SGI Indy Video/Galileo). The 2.7 software architecture has been completely re-done from 2.6 and adding support for new hardware or hardware capabilities should be much easier. 2.7 should also fix several robustness and performance problems >from v2.6. This alpha-test is intended for sites who are interested in fielding the new release and are willing to debug and report problems. This is *not* a stable, general public release. Once the alpha testers have tripped over the major bugs, we intend to do a general release. This will include updated vic binaries for most supported systems.

Satellites represent a crucial element of the global information infrastructure and are experiencing a quiet technology revolution that will multiply their capabilities significantly. The recent launches of OLYMPUS in Europe and the ACTS in the United States have proven that on-board processing, bandwidth-on-demand, switchable spot-beams, and the use of the Ka-band can convert, until now, the passive "bent-pipe" reflectors to powerful, full-fledged network nodes. The satellite advantages of ubiquitous coverage, easy access, large bandwidth, immunity to terrestrial catastrophes, and relatively low-cost add up to make satellites indispensable as parts of the worldwide information highway. The much discussed personal communication systems that are currently under development, from Motorola's Iridium to the Teledesics bold constellation concept, demonstrate one aspect of the envisioned role of future satellite systems in the mobile communication area. The main technical bottlenecks that must be overcome to permit the seamless incorporation of satellites into modern hybrid networks and their transparent interoperability with terrestrial links (whether wireless or not) include: - The mismatch of bandwidth, error-rate, and propagation delay properties between satellite and terrestrial links. - The need for seamless network protocol operation - The differences among the multiple services anticipated by such networks in the emerging multimedia markets - The congestion, access, admission control, and bandwidth allocation problems - The cost of terminal manufacturing with dual (space/terrestrial) capabilities - The regulatory, standardization, pricing, and other commercial and business issues that impact the operation of such systems.

The conference organizers wish to announce that two sessions will be broadcast using m-bone technology. The first session will be the keynote address by Clifford Lynch. Clifford is planning to discuss implications of web browsers for the design of online catalogs and related information retrieval systems, and architectural issues involved in Z39.50 "clients" and web browsers. This broadcast will take place on Monday, October 23rd at 8 AM EDT. The second broadcast will be at 6 PM EDT, Tuesday October 24th. David Seaman, Coordinator of Electronic Texts, University of Virginia, will be speaking on the future of Electronic Publishing. Technical notes: The technical contact for these broadcasts is Dwight Spencer (spencer@unb.ca). He sends us the following technical information: We will be using NV and vat, with a ttl of 127, with nv possibly sending cusm encoding if we get our cusm reflector and vat working. nv will be using a bandwidth of ~70kbps, and audio (vat) format may be idvi. Rebroadcasts are possible and will be announced at a later date. Also possible are CuSeeMe broadcasts at the times mentioned. If we can get the audio working properly, the reflector will be irc.unb.ca. Thanks to Clifford Lynch, David Seaman, Dwight Spencer, Steve Sloan and UNB's Computing Services for making this possible.

I think that keys should be case-sensitive. The smaller the character set we choose from, the longer the strings we need to ensure security. Assuming random keys, this makes only a small difference for example - 62^13 < 36^16 < 62^14. In practice, random keys are unlikely to be used by most users, and given the proposal to limit keys to alphanumeric, it's likely that many users will resort to dictionary words, which makes it rather easier than it should be to crack even a reasonably long key. A liberal sprinkling of capitals is one of the normal partial solutions to such problems, and although not a good solution, it's better than nothing. I'm concerned that if keys are not case-sensitive, most users will have trouble coming up with secure keys. A year ago, I would have reckons case sensitive keys were a bad idea for all those PC users out there, but anyone who's typed a URL probably knows about case-sensitivity by now. As for dots and commas being too similar on faxes - you could always map commas to dots! When our students first arrive, they get randomly allocated passwords - the ones with |,1,I or l in them inevitably have problems. How far down this track do we wish to go? I'd like to see a few non-alphanumeric characters allowed, as they too help to make better keys slightly easier to think of. This could get really arbitrary though if we're not careful. Does anyone have a good suggestion, other that alpha-numeric only?

[Jed] Donnelley) Subject: Multicasting with ATM - a concern Cc: rem-conf@es.net I would like to raise a concern I have about approaches and progress on multicast over Asychronous Transfer Mode (ATM) technology (adapters, switches, etc.). I will admit upfront that I do not have complete knowledge of where progress is being made in this area. It is an area that I dabble in but am not actively involved in. I could just let my concern go, but decided to try to clarify it with this message. I'm ready to be blasted, but I hope I'm blasted with some pointers to some new information on multicast over ATM. Having read the Internet-Draft "Support for Multicast over UNI3.1 b ased ATM Networks" - draft-ieft-ipatm-07.txt, I am concerned about the direction that seems to be being taken. In that document there are two approaches described for routing multicast packets (independent of how multicast groups are set up): 1. Meshes of point to multipoint Virtual Circuits (VCs), or 2. routing multicast packets through a multicast server (MCS) that has a single point to multipoint VC to all the leaf notes of a multicast group. Both of these approaches seem quite poor to me. They are both serious steps backwards from the sort of mechanisms that are currently available for IP multicast (either on MBone or in multicast capable routers). It seems to me that what is needed is some sort of multicast virtual circuit. With such a circuit, nodes could join locally and have their cells routed (through a table in the ATM switches much like with unicast or point to multipoint VCs) to the appropriate next switches (much like as now happens with IP multicast). Specifically cells would not be routed back to where they came >from (e.g. as happens with the MCS approach). Also, only one such structure would exist in any switch for a multicast group (unlike with the mesh of VCs approach which has one point to multipoint VC for every leaf node transmitter in a multicast group). Can anyone give me a pointer to work on ATM multicast beyond that described in the draft-ieft-ipatm-07.txt? It would seem that such work would require a UNI beyond 3.1 with perhaps some support for direct multicast VSs? Any pointers and/or suggestions are welcome.

Date: Mon, 16 Oct 95 13:47:45 PDT From: Van Jacobson Eric, I believe you are describing administratively scoped multicast. With Steve Deering's help, I made a proposal for making the top 24 bits of the class D address space administratively scoped and described the semantics and implementation. This was presented to the IETF IDMR working group in Toronto, July '94, then subsequently adopted. (The talk slides are available as ftp://ftp.ee.lbl.gov/talks/adminscope.ps.Z) All the necessary pieces to implement administratively scoped addresses are in the current mrouted (3.6) and I believe cisco either has or is close to having support for them. I don't know about other vendors. I believe IANA has been asked to mark the address block 239.0.0.0-239.255.255.255 as reserved for admin scoped multicast but the the last time we checked this hadn't happened yet. - Van From rem-conf-request@es.net Mon Oct 16 18:37:58 1995 Received: from fnal.fnal.gov by osi-west.es.net with ESnet SMTP (PP); Mon, 16 Oct 1995 15:36:50 -0700 Received: from munin.fnal.gov by FNAL.FNAL.GOV (PMDF V4.3-12 #3998) id <01HWILL2PF9C000GGY@FNAL.FNAL.GOV>; Mon, 16 Oct 1995 17:36:46 -0500 (CDT) Received: from LOCALHOST.fnal.gov by munin.fnal.gov (4.1/SMI-4.1-m) id AA22323; Mon, 16 Oct 95 17:35:31 CDT Date: Mon, 16 Oct 1995 17:35:30 -0500 From: Matt Crawford Subject: Re: Local Class D Addresses In-reply-to: Your message of Mon, 16 Oct 95 13:47:45 PDT. <199510162047.NAA03270@rx7.ee.lbl.gov> Sender: crawdad@munin.fnal.gov To: Van Jacobson Cc: rem-conf@es.net Message-id: <9510162235.AA22323@munin.fnal.gov> Content-transfer-encoding: 7BIT X-Face: /RKQi"kntyd}7l)d8n%'Dum<~(aMW3,5g&'NiH5I4Jj|wT:j;Qa$!@A<~/*C:{:MmAQ:o%S /KKi}G4_.||4I[9!{%3]Hd"a*E{ I believe you are describing administratively scoped multicast. > ... presented to the IETF IDMR working group in Toronto, July '94, I couldn't find this in the internet-drafts or the rfc-index.

There is actually a working solution to multicast on ATM, it's available and working (beleive it or not). Fore has an nice form of multicast support in their geirs, they use their propritary SPANS and Fore IP to have a propper multicast. They have the switches makeing the forwarding in the same fashion as ordinary multicast routers but they do it with the ATM cells. SPANS and Fore IP actually performs the routing and forwarding mechanism in the same fashion as DVMRP does. So I guess that such support could be implemented into any switch that do propper point-to-multipoint forwarding in hardware. With propper I mean that it also could do things like changeing VP and VC of the header. I have some Fore documents describeing this, but I dont now if I can spread them, so ask some Fore people. They have a www server which should give some info.

David, Of the machines we have locally (SS-20s, an SGI Indy, a DEC Alpha, an HP 735, various 486 boxes), the Alpha with a J300 capture board sending & receiving motion-jpeg video gives the best raw performance. The J300 does both hardware compression & decompression and can decompress directly to an X window (vic has support for this hardware renderer). Since dedicated hardware does all the work, the setup can easily handle multiple 30 f/s video streams. The SunVideo capture board in the SS-20s is nice -- there's a programmable processor on the board that can be do jpeg & mpeg compression -- and vic will easily source 30f/s motion-jpeg video from an SS-20. But we have the slowest, uniprocessor sparc model (20-50?) and, since it has to decode and render in software, it only manages ~15f/s. We have a fairly fast Indy (134MHz R4600?) that does substantially better on software decode (20-25f/s) but SGI's video capture options are less than stellar - you can get fast, cheap, raw YUV video >from the on-board VINO video but you have to software compress it which is fairly slow (<15f/s). There is a hardware jpeg compressor available, the Cosmo Compress option to the Galileo/Indy Video, but it's very expensive & doesn't perform as well as the J300 or SunVideo. The above gives the fastest framerate. That's a big component of user perceived quality but not the only one. The J300 hardware renderer dithers 24-bit YUV into an 8-bit frame buffer. It does a very good job of dithering but I still find the noise introduced by dithering objectionable. The SS-20s & Indy both have truecolor (24 bit) framebuffers & vic has a very fast YUV-to-RGB truecolor software renderer. My guess is you'd get the best compromise between high rate & high quality rendering with vic on an SS-20 sending motion jpeg (but not displaying anything) & vic on fast Indy(s) with a 24-bit framebuffers displaying the video using the truecolor renderer. - Van From rem-conf-request@es.net Tue Oct 17 15:00:19 1995 Received: from paradise.CS.Berkeley.EDU by osi-west.es.net with ESnet SMTP (PP); Tue, 17 Oct 1995 11:59:47 -0700 Received: (alicef@localhost) by paradise.CS.Berkeley.EDU (8.6.10/8.1B) id LAA02406; Tue, 17 Oct 1995 11:59:45 -0700 Date: Tue, 17 Oct 1995 11:59:45 -0700 From: Alice Ford Message-Id: <199510171859.LAA02406@paradise.CS.Berkeley.EDU> To: rem-conf@es.net Subject: reminder of MultiMedia Seminar 10/18 Cc: alicef@paradise.CS.Berkeley.EDU Multimedia and Graphics Seminar (Wed Oct 18, 1995 12:30-2:00 PDT 405 Soda Hall) Computer Graphics Animals: A Report from the Field Eric Enderton Industrial Light and Magic Industrial Light & Magic has been working towards the ability to produce computer-animated animals of natural appearance and organic behavior, seamlessly merged with live-action film footage. This talk describes our overall process and some techniques used in each stage. Videotaped examples from the motion pictures Jurassic Park and Jumanji will be shown. Digital models, animations, and texture maps each contain a large amount of digital information. While this information can be created by digitization of actors, physical objects, photographs, or performances, it is more often created directly by an artist using a computer program. Animation is still hard. One interesting problem is to bridge the gap between the rigid, angular motion of an animated hierarchical skeleton and the smooth motion required of the surrounding skin. Most often, techniques that amplify the artist's control are more useful than techniques that are completely automatic. <><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><> www-plateau.cs.berkeley.edu/298 for further information.

This version of vat conforms to the final (RTP-7) Internet Draft for the IETF AVT Real Time Transport protocol. We've made vat-4 upwards compatible with vat-3; i.e., it is a drop-in replacement for vat-3 and by default will come up speaking the old vat protocol. However, vat-4 accepts a "-r" flag or "Vat.sessionType: rtp" Xresource to support sessions using the RTP protocol. RTP is far superior to the original vat protocol and we hope it will soon become the default but in the interim we have to figure out the right sequence of tool deployment and sd/sdr changes to coordinate an orderly transition between the two protocols. This alpha-test is intended for sites who are interested in fielding these new releases and are willing to debug and report problems. Vat's internal architecture has changed substantially in the last few weeks (leveraging off the RTPv2 and tcl/c++ framework from vic), and we expect that it will be a few more weeks before the release stabilizes.

To commemorate this event, the Crew intends to broadcast live and recorded footage that week of the regatta, to allow scholars and sports fans alike to the treat of viewing their home clubs and colleges race without having to the hundreds or thousands of miles that many national and international teams must travel to compete here in Boston. The MBone broadcast will take place from the Multimedia Communcations Laboratory at Boston University and will be announced on sd. Head Coach Rodney Pratt has provided his full support in the development of this site, which features photographs and "morphed" sequences of the Crew members, as well as biographies of the coaches and captains. Via the BU Multimedia Communications Lab, crew video sequences are also available in the home site, as well as the special MBone broadcast during the Regatta week launch. The site also features aspects of rowing in Boston, with a clickable map of the Charles River and information on local boathouses and clubs as well as Boston University's world class Crew. The URL for the new site will be "http://web.bu.edu/CREW/" (upper case CREW). The site authors may be reached via email at jrhee@bu.edu (John Rhee) and philip1@bu.edu (Philip Michaels) -- ================================================================ Dinesh Venkatesh Multimedia Communications Laboratory, ECS Department ERB 236, 44 Cummington St., Boston University, Boston MA-02215.

Messerschmitt EECS Department, U.C. Berkeley Networks for multimedia must accomodate audio, video, graphics and data, and also satisfy a variety of requirements such as high subjective quality, high traffic capacity, low cost, functional requirements such as privacy and multicast, and flexibility and extensibility, all in a heterogeneous terminal and transport environment. Achieving these goals will require a carefully crafted architecture that anticipates these issues and their interaction. Taking a longer-term research perspective, it is important to identify key obstacles and bottlenecks that constrain performance and traffic capacity and which cannot be mitigated by mere advances in technology. Two such bottlenecks can be identified. First, network latency is lower bounded by propagation delay, which is already quite significant in critical interactive applications in a global-scale network (hundreds of millisec). Thus, there is little opportunity to add additional delay without serious impact on some applications. Second, the traffic-carrying capacity of interference- and/or fading-limited wireless access links is subject to fundamental limits that will be increasingly constraining relative to broadband backbone networks. We describe the architecture we have defined in the Infopad wireless multimedia networking project at Berkeley to address these issues, as well as briefly summarize some detailed work in video compression and CDMA media access that are coordinated with this architecture.

Messerschmitt EECS Department, U.C. Berkeley Networks for multimedia must accomodate audio, video, graphics and data, and also satisfy a variety of requirements such as high subjective quality, high traffic capacity, low cost, functional requirements such as privacy and multicast, and flexibility and extensibility, all in a heterogeneous terminal and transport environment. Achieving these goals will require a carefully crafted architecture that anticipates these issues and their interaction. Taking a longer-term research perspective, it is important to identify key obstacles and bottlenecks that constrain performance and traffic capacity and which cannot be mitigated by mere advances in technology. Two such bottlenecks can be identified. First, network latency is lower bounded by propagation delay, which is already quite significant in critical interactive applications in a global-scale network (hundreds of millisec). Thus, there is little opportunity to add additional delay without serious impact on some applications. Second, the traffic-carrying capacity of interference- and/or fading-limited wireless access links is subject to fundamental limits that will be increasingly constraining relative to broadband backbone networks. We describe the architecture we have defined in the Infopad wireless multimedia networking project at Berkeley to address these issues, as well as briefly summarize some detailed work in video compression and CDMA media access that are coordinated with this architecture.

Good question and I don't have a good answer at this time. Perhaps the best PC sound card for audio conferencing which Voxware (the linux sound driver) supports is the Advanced Gravis Ultrasound. Under FreeBSD we have supported full duplex audio for about 3 years now with the GUS and the PAS16. The GUS has a problem of mixing input and output which can be alleviated by using headphones. The PAS16 or at least some PAS16 tend to lock up periodically. The GUS MAX via the CS4231 mixer interface supports dual dma and separate output and input;however; the GUS MAX with rev higher than 1.8 have a hardware bug which tend to lock up a system solid if one tries to access the card using dual dma via the CS4231 mixer. Hopefully, the new cards from Gravis and Creative Labs will have correct dual dma and mixer behavior. >>> Toerless Eckert said: > Hi > > I guess this topic has been touched before, but luckily i didn't > have to worry about it.

Some new video graphic cards such as Diamonds S3 968 PCI with their Motion Player daughter card do have audio capabilities so in theory we should be able to also use our video graphic boards for not only video conferencing but also for audio conferencing. I am speculating here a little because I am waiting on the docs from Diamond for my Diamond S3 968/Motion Player so I don't know if the card supports audio dma or dma for any its video/audio components. Incidently, the Motion Player can dump raw video straight into the S3's frame buffer :) Enjoy --- Amancio Hasty Hasty Software Consulting Services Tel: 415-495-3046 Fax: 415-495-3046 Cellular: 415-309-8434 e-mail: hasty@star-gate.com Powered by FreeBSD From rem-conf-request@es.net Tue Oct 24 19:52:07 1995 Received: from ibeam.intel.com (actually ibeam.jf.intel.com) by osi-west.es.net with ESnet SMTP (PP); Tue, 24 Oct 1995 16:51:34 -0700 Received: from ishark.intel.com by ibeam.intel.com with smtp (Smail3.1.28.1 #6) id m0t7t7N-000RV3C; Tue, 24 Oct 95 16:50 PDT Received: by ishark.intel.com (Smail3.1.28.1 #6) id m0t7t7L-0004zMC; Tue, 24 Oct 95 16:50 PDT Message-Id: To: rem-conf@es.net Bcc: Subject: Looking for G.711 RTP payload specs Date: Tue, 24 Oct 95 16:50:50 PDT From: Linda Cline Hello, I'm trying to locate any existing specification for G.711, for RTP payload definition.

Since their introduction 6 years ago both have evolved based on user experience by adding ideas from each other and from other methods. This talk describes the unification of the Booch and OMT methods by Grady Booch and Jim Rumbaugh leading to the recent public release of over 100 pages of documentation describing the Unified Method models and notation. The authors are now awaiting public feedback before completing a final version of the method Contents: The Drive to Unification - why and how it happened The Unified Metamodel - the formal description of the models The Unified Notation - the new notation based on Booch and OMT Future Work - open problems that we are working on Roadmap - how users can get involved The Speaker: James Rumbaugh is a Fellow at Rational Software Corporation. He has been active in object-oriented technology for many years and has taught the OMT methodology around the world.

Srin Data Flux Systems Inc. Berrkeley, CA The design and development of a hardware system comprising interfaces for receiving multimedia data from many sources, a compression engine for MPEG-2 standard, a decompression system for MPEG-2 encoded system packets, an image processing system, and a graphics system for overlaying digital special effect is the focus of this talk. The hardware system, called MediaBox, can be connected to a PC or a workstation. The central part of MediaBox is a high bandwidth interconnection network. The functional units of the MediaBox communicate using the interconnect network. The multimedia data is stored locally in SCSI-3 disk drives. Interfaces for TV antenna, DBS antenna, cable, ISDN, POTS, and CDPD are an integral part of MediaBox. NTSC/PAL video decoders allow motion video clips to be color space converted, digitized, and submitted for storage or compression. A video encoder receives digitized data, encodes it to NTSC/PAL signal, converts it to analog form, and makes it available for display using a monitor. Two implementations of the MediaBox are in progress. The first implementation uses a PCI bus for the interconnection network. The second implementation is based on an 8 X 8 crossbar with byte wide data path operating at 400 MHz. The implementations use Hyundai's HDM 8211M VLSI chip for MPEG-2 decoder, C-Cube's CL4600 VSP chips for MPEG-2 encoder, NCR's VLSI chip for SCSI-3 controller, TI's MVP for image processing, AMCC's S5933 chip for PCI bus interface, Brooktree's BT 812 for video decoding, and Bt855 chip for video encoding. Some of the details of the hardware implementation will be discussed. <><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><> www-plateau.cs.berkeley.edu/298 for further information. The seminar will be broadcast on the Internet MBONE starting at 12:40. The Fujitsu Seminar room (405 Soda) has approximately 30 seats. Folks at Berkeley might want to attend the seminar by watching it on your workstation, if you can receive MBONE transmissions. Due to problems at Berkeley, this seminar will not be available over the BAGNet. We hope to have the problems resolved in time for next weeks presentation.
