MPEG ES's can't use 00B in this field because of the "start code emulation problem"; but, this does not apply to the RTP header. Given that there isn't any proposal for increasing the number of usable picture types in MPEG-(1 & 2) to more than four, two bits should be sufficient. On the other hand, if this document is still being modified, it will definitely benefit from some additions/explanations about MPEG-2. Specifically, indicating that: 1. FBV, BFC, FFV and FFC fields are useless for MPEG2 2. the described error recovery techniques won't apply to MPEG-2 in general because the information contained in the MPEG specific header is inadequate. For a more robust encapsulation approach for MPEG-2 you may consider looking at: draft-civanlar-bmpeg-00.txt ( http://www.netlabs.net/hp/rcivanlar/draft-civanlar-bmpeg-00.html ) which describes a bundled payload; however, contains many ideas applicable to a video only encapsulation also.

It is possible for two sockets to bind() to the same port if the REUSEADDR socket option is set. Note, however, that how datagrams are delivered when requested by multiple sockets is highly implementation specific. I have actually done what you want. The technique I used was to connect() my receiving socket specifically to the port of vat's sending socket before running vat (this requires guessing what the port number will be :( ). Then, the idea is that the OS _should_ deliver data from vat to my receiving socket since its connection is more specific than vat's receiving socket. This works under Linux, Irix, and AIX, but notably not under any version of SunOS. All of the above must be repeated twice of course, once for the data channel and once for the control channel. This is a very messy technique, and should be avoided if you have the means. Another possibility is to use a local multicast group. However, this requires a multicast capable interface, such as an ethernet, and which the loopback usually is not. As a side note, this is a general problem among multicast applications, in the name of simplicity (one port for the conference). Has anyone ever thought of implementing a more general scheme, in which sending and receiving ports could differ? I hope this helps, Andrew Booker andy@Virginia.EDU From rem-conf-request@es.net Thu Sep 05 14:38:11 1996 Received: from bmrc.Berkeley.EDU by osi-west.es.net with ESnet SMTP (PP); Thu, 5 Sep 1996 11:37:36 -0700 Received: from nobozo.CS.Berkeley.EDU (nobozo.CS.Berkeley.EDU [128.32.34.58]) by bmrc.Berkeley.EDU (8.6.11/8.6.9) with ESMTP id LAA08332 for <298-list@bmrc.Berkeley.EDU>; Thu, 5 Sep 1996 11:33:30 -0700 Received: from sockeye (sockeye.CS.Berkeley.EDU [128.32.36.74]) by nobozo.CS.Berkeley.EDU (8.6.10/8.6.3) with SMTP id LAA01638 for <298-list@bmrc>; Thu, 5 Sep 1996 11:33:31 -0700 Date: Thu, 5 Sep 1996 11:33:31 -0700 Message-Id: <199609051833.LAA01638@nobozo.CS.Berkeley.EDU> X-Sender: jerrlyn@nobozo.CS.Berkeley.EDU X-Mailer: Windows Eudora Version 2.1.1 Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" To: 298-list@bmrc.Berkeley.EDU From: Jerrlyn Iwata Subject: Berkeley Multimedia and Graphics Seminar Berkeley Multimedia and Graphics Seminar Wednesday, September 11, 1996 12:30-2:00 p.m. PDT 405 Soda Hall "Payment Systems for Electronic Commerce" Einar Stefferud Network Management Associates Commerce has come to the Internet and it demands that we find ways to transfer money via the net.

This is our setup: every Wed night we (NCSU) have been broadcasting an interactive graduate class to UNC-Asheville (TTL is set to 63). So far it has been an amazing success. NCSU transmits the professor's video and audio to Asheville and likewise they transmit their video and audio (when a question is asked). I receive the prof's lecture slides on Wed afternoon (class is at 5pm) in MSWord format. I have a PC in my lab running Win95 with Word7. I print out the slides in ps format (optimized for compatibility - I've also tried optimized for speed) and use "pssplit -lz" to split and compress them. Even after this though there are about 10 slides (out of 30) that are above the 32K limit. I tried using the distill function with a gs interpreter, but all that does is give me garbage ps that I can't bring in ghostview/gs, or wb. So to get around this, I've bring up the slide in question in ghostview and use xv to take a snapshot of a region around the slide. I then save the snapshot as ps file. I then use lzps to compress it and so far all slides have been come in under the limit using this technique. I must mention that these slides in question are all graphics (Harvard graphics to generate (I think) and then imported into MSWord). Wb is able to load these slides, but it takes an enormous amount of time (30-45sec). I could have sworn that I remember reading somewhere that you can up the limit on ps file size up to 1M. I certainly don't need that much, but am looking for ways to minimize that load time. I'm thinking that compression upon compression is slowing it up. Does anybody know how to do this? I haven't been able to find that specific reference to it, merely a vague one that says you can get around the ps limitation (so maybe I'm not going senile! :-) The prof. is using a DEC Alpha station to control the wb and his audio. I don't have a wbimport that works on this station. It says it needs tk v3.4 or later, but I have v4.0 on it. So anyway, I've been trying to recompile wbimport with little success. He's been forcing the students to a new slide by making a mark up in the corner of the slide. He comes into the classroom early and preloads the 30 slides into, but those "rigged" slides still take the same amount of time to load for him as it does for everybody else. I'm thinking that cache size has something to do with this? Another question while I'm at it :-) While we've used the MBone for the class itself, we're currently using the MBone tools in a unicast mode for office hours. We're having problems with the quality we're getting. There is a lot of loss in the audio quality and wb was dropping about every third typed character. Can somebody explain what the difference is when you use the MBone tools in a multicast session vs. an unicast session? I've viewed MBone sessions during peak network times and there is some loss - but not as much as I've seen with unicast sessions. Thank you for any and all help that can be given.

Thus, if you're interested in participating in the W3C workshop on "Real-time Multimedia and the Web", please submitt a short position statement (one to five pages) to hoschka@w3.org until Friday, September 13 (HARD DEADLINE !) http://www.w3.org/pub/WWW/AudioVideo/RTMW96.html [Image] CALL FOR PARTICIPATION World Wide Web Consortium Workshop "Real Time Multimedia and the Web" (RTMW '96) October 24-25, 1996 INRIA-Sophia Antipolis - France NEW ! Submission Deadline extended: Friday, September 13 [Version francaise] ---------------------------------------------------------------------------- SCOPE In the last year, there has been an increasing interest into the integration of audio and video into the Web. The Web offers the unique opportunity of fully integrating audio/video with many other media types (hypertext, images, ...), making Web technology a contender for the "television of the future". However, lacking both a forum for standardisation and a common reference implementation, current solutions for audio/video integration into the Web tend to be piecemeal and non-interoperable. The purpose of this workshop is to provide a forum for exploring future directions of standardisation process in this area within the W3C (WWW Consortium). Participants will be representatives of W3C member organisations and other qualified experts from research and industry. We solicit short position papers (one to maximally five pages) describing anything from a "wild idea" to a complete specification or implementations. The main areas of interest include (see also "W3C Activity: Audio and Video"): * Building Web-based multimedia presentations o Time representation and media synchronisation o Defining audio/video presentation * Audio/Video hyperlinks o URL's for linking into audio and video files o Addressing "streaming" audio/video resources via URL's o Embedding URL's into audio and video streams * Audio/Video media formats o Describing the format of audio/video resources o A common fall-back format for audio and video data * Integration of RTP (Real Time Transport Protocol) * Multicasting and the Web ---------------------------------------------------------------------------- INFORMATION TO CONTRIBUTORS There will be a limit of 70 participants. There is no registration fee. Potential participants should submit to the workshop chair short position papers of one to five pages. Most importantly, the paper should state clearly your potential contribution to/idea on the integration of real-time multimedia into the Web. The papers can be submitted via e-mail (preferred) or in paper form. Allowed formats for e-mail submissions are, in order of preference: a URL to the paper, HTML, Postscript, PDF, RTF and ASCII. Papers will be reviewed by the program committee. Based on the reviews, we will ask a subset of participants to present talks. To maximize the time spent in interactive discussions, not all attendees will make presentations. However, all position papers will be included on the workshop website, and will appear in the printed participants' proceedings. W3C may also publish accepted papers. Note: The website will be available ot the general public, so position papers must be available for public dissemination. Workshop participants may also be interested visiting the "Protocol for High-Speed Networks" conference, which is scheduled at INRIA Sophia-Antipolis in the week after theW3C workshop. ---------------------------------------------------------------------------- PUBLICATION Papers will be made available on the Web. Printed participants' proceedings will be distributed to workshop attendees. W3C may also publish accepted papers in other media. ---------------------------------------------------------------------------- IMPORTANT DATES: Today: Send a message the workshop chair stating your intention to submit a paper, or your general interest in the workshop.

First we can't use your second suggesstion about multicast, because the program I write will be an encrypting application. This means only my program should be capable of reading the data before its encrypted. Your first suggestion seems to be good, I tried this before, without any success. Maybe there is a point I overlook. Could you please send me your program?

I'll try to pull a more legible copy. Allison, you and Steve probably have the most documentation of the mbone (or other) experiments which predate the subject patent. Jeff Pulver has proven himself an effective advocate of realtime over the Internet (his VON Coalition pulled together an effective response to the ACTA filing against Internet Telephony with the FCC). I encourage you to send a note to Jeff if you have such documentation of prior art. (I would also appreciate a copy, thanks!)

In this case, the threat is that the government will issue patents that have broad claims that can be used to tax our industry or even put people out of business. The US patent system is not a perfect system, and often patents get through that should never get through. For those of you in the industry, you need to know about a recent patent (US Patent No. 5,526,353) that issued to Henley and Grau in June 1996. Let's call this the "Henley Patent". The inventors of this patent claim to have invented sending and receiving audio over packet-based networks. (Note: A copy of the patent was distributed with the conference materials at the Talking Net conference last week.) Such a claim would broadly cover all Internet telephony and any product that sends and receives audio over packet-based networks. Henley and Grau claim to have invented audio over packet-based networks in 1994, because they filed the patent application on December 20, 1994. Most people's first reaction to this is that this patent could never be valid. People were experimenting with and selling product for voice over packet-based networks in 1993. (I know I was). But the patent has already issued so it has the power of the US government behind it. So, what can we do? As an industry, we need to accumulate product literature, technical literature, conference proceedings, or any other public or private written disclosure that shows that people were sending and receiving packetized audio prior to December 20, 1993. This is the date one year before the filing of the patent and there is no way that Henley and Grau can claim to have invented this prior to any public information that was available prior to December 20, 1993. This will allow us to develop a storehouse of information that will show that this patent should never have issued. It is important that we respond to this as a unified industry, for the good of the entire industry.

On RFCs, go to the IETF(Internet Engineering Task Force) home page, the things that you want to look at are RTP(Realtime Transport Protocol) and RSVP(ReSource ReserVation Protocol), if you have time, there are a ton of other proposals in the general area of multimedia over Internet. As a matter of fact, RSVP, RTP and its offshoot XTP(eXpress Transport Protocol) have their own respective home pages in the Web. As I have posted in the past and what I beleive what Howard from Xing was saying, Interent broadcasting is a new technology and that traditional broadcast is really not a good model on how this technology should be employed. In the area of quality of service(QoS) on Internet multimedia delivery, as in most cases, technology is not a problem, the problem is really economics(as usual). In the most recent InterOp, Cisco and MCI, et al have demonstrated RSVP connections, in other words, guaranteed QoS multimedia stream realtime delivery. Right now this technology is targeted at the corporate private network(intranet) market. The problem of deploying this technology in the public sector is obvious: how much will the users be willing to pay for guaranteed QoS ? The same type of "will people willing to pay ?" problem is common to all these much talk about technologies, such as xDSL, Fibre to home,..... In Mar/April's IEEE Network publication, the editor(Mr. David C. Feldermeier) made an interesting observation, very much in line with my personal experience, and I quote verbatim,: "In my experience, people tend to be very careful with their own money, and not so careful with someone else's money, I am constantly seeing market studies in which people are asked what new communications services they might like. When money is not mentioned, people are interested in all kinds of new services. However, as soon as you tell people that some new service will cost $50 per month(or whatever), interest drop to practically zero..." stevec ------------------------------ End of Voice On the Net Digest V2 #231 ************************************** (c) 1996 Jeffrey L.

While I also agree that a 94 patent on packet audio should be indefensible, we still need to focus on getting all of the materials together so that I or somebody else can make a case to the US Patent Office that this particular patent should not have been issued. If anybody could point me toward additional related URLs - I will add them to my list. Also - If somebody could suggest additional net resoures - mailing lists and/or usenet groups to post to, I would greatly appreciate it.

Perkins ======================================================================== Baltzer Science Publishers in cooperation with ACM announce a Special Issue of the Journal on Special Topics in Mobile Networking and Applications (MONET) on Mobile Networking in the Internet with guest editors Charles E. Perkins IBM T.J. Watson Research Center David B. Johnson Carnegie Mellon University OVERVIEW: The continued exponential growth of the Internet, coupled with powerful new technology for wireless computing, has created the need for extensive development of protocols and techniques for handling wireless nodes as they move about and change their point of network attachment. One major technological advance enabling mobile networking within the Internet has been Mobile IP, developed within the Internet Engineering Task Force (IETF), but this is only the beginning of the wave of changes needed to support nomadic Internet users. Problems introduced by mobility have been identified at every level of the network protocol stack, and many innovations are needed to enable the full potential of untethered nodes within the Internet. SCOPE: This special issue will concentrate on the problems associated with mobile and wireless networking in the Internet, primarily at the network layer and above. A representative sampling of topics is provided below: - Mobile IP - Registration and location management - Route optimization - Interactions between geographic and network locality - Mobile multicast protocols - Mobile location of services and resources - Transport layer (TCP, RTP) effects - Multimedia and QOS support - Internet protocols in a wireless ad hoc network - Application adaptation to mobility and changing links - Proxy architectures for Web and other services - Internet security issues - Analysis and simulation of mobile networking protocols - Mobile node traffic analysis and simulation SUBMISSION GUIDELINES: Authors should email an electronic Postscript copy of their paper to one of the guest editors by November 15, 1996. Submissions should be limited to 20 double spaced pages, excluding figures, graphs, and illustrations. If email submission is impossible, then six (6) copies of the paper (double-sided if possible) should be sent by the due date to one of the guest editors.

From its origins as a US government research project, the Internet has grown to become a major component of the global world-wide network infrastructure, linking millions of machines and tens of millions of users around the world. If the Internet were a stock it would be considered a market phenomenon, with sustained double-digit growth and no apparent end in sight to its upward spiral. Over 70 countries have full TCP/IP Internet connectivity, and about 150 have at least e-mail services through IP or via more limited means of connectivity (e.g., UUCP or Fidonet). Given such phenomenal growth, the Global Internet is increasingly viewed as the catalyst for a communications revolution resulting in a plethora of new technological, economic, and social changes. The focus of the special issue is on the technologies of the Internet, the technological changes driven by the emergence of a truly Global Internet, and collateral economic and social issues. Papers are solicited on the following specific subjects: * Internet Applications - information retrieval, directory services, catalogs, search tools and user agents; electronic publishing; education; www; languages; collaborative work environments. * Internet Connectivity Infrastructure - service characteristics ("best effort" vs. guaranteed); reliability (utility); addressing; multicasting; routing; protocols. * Internet Administrative Infrastructure - regulation; public policy; economics; standards. * Internet Security - security technology; export controls; privacy. * Internet Management - protocols; agent technology; standards; platforms. * Internet Commerce - electronic banking; virtual retailing; payment systems. Submitted manuscripts must be no longer than 12 single-spaced pages. The cover page should include the title of the paper, a brief abstract, a list of keywords, and the full name, affiliation, postal address, telephone number, and electronic mail address of each author. Papers may be submitted in postscript format via e-mail or as hardcopy (six copies). Authors should obtain company and government clearances prior to submission of papers. Papers should be submitted by October 31, 1996 to either of the guest co-editors. All papers will go through a peer-review process. They will be judged with respect to their quality and relevance to the Special Issue and the IEEE Communications Magazine. Authors will be notified of acceptance or rejection by December 15, 1996. Final copies of accepted papers will be due by January 31, 1997. Publication is scheduled for May 1997.

The patent is the collection of *all* the claims, not just one. This patent has 40 claims, some of which are pretty fuzzy (for example claim 26 speaks of periods of "about" 20 milliseconds.) It wouldn't be surprising if the patent is actually pretty narrow (but one would have to have a readible copy, something it seems that few of us have, plus rather many hours of boring reading, to even begin to find out. There's also a lot of very esoteric law on how one interprets this stuff.) A comment on prior art -- I'm not an expert in this, but it is my understanding that the US Patent and Trademark Office does not recognize a lot of what we do in the net as constituting "prior art", at least not that which the USPTO takes cognizance of without some special prompting. In general they look to established journals and other patents. And we, being more e-mail based, tend to not follow the formal journal paradigm found in other scientific and engineering areas. One might also expect that "prior art" needs to be readily findable through normal library indexing systems. (I would hope, however, that IEEE and ACM proceedings would constitute the kind of thing the USPTO recognizes.) By-the-way, our practice of destroying internet drafts and such doesn't help our case when we start shouting "prior art, prior art". All this said, it certainly won't hurt to gather all relevant references and documents from the past so that someone who wants to challange the patent can be well armed. --karl-- From rem-conf-request@es.net Mon Sep 16 19:03:15 1996 Received: from broon.off.connect.com.au by osi-west.es.net with ESnet SMTP (PP); Mon, 16 Sep 1996 16:02:13 -0700 Received: from connect.com.au (ggm@localhost) by broon.off.connect.com.au with ESMTP id JAA06803 (8.7.4/IDA-1.6); Tue, 17 Sep 1996 09:01:13 +1000 (EST) X-Authentication-Warning: broon.off.connect.com.au: ggm owned process doing -bs X-Mailer: exmh version 1.6.6 3/24/96 To: Karl Auerbach cc: Jeff Pulver , Jon Crowcroft , ellesson , casner , mankin , rem-conf Subject: Re: Packetized Audio Patent In-reply-to: Your message of "Mon, 16 Sep 1996 15:07:23 MST." <9609162207.AA16395@precept.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Date: Tue, 17 Sep 1996 09:01:12 +1000 Message-ID: <6802.842914872@connect.com.au> From: George Michaelson From: http://www-nrg.ee.lbl.gov/vat/ Acknowledgments --------------- Funding for this work was provided by the Office of Energy Research, Mathematical, Information, and Computational Sciences Division, of the U.S. Department of Energy under Contract No. DE-AC03-76SF00098.

In terms of complexity and performance for this particular task, there seem to be encodings which are superior in terms of complexity, performance and availability of source code.

I was one of the chief architects for a packet switch/router which put 200Mbs to the desktop and in the lab packet switched 100,000+ packets/sec. The switch was called SuperMAN. ATT marketing saw no future in the switch but quite a few patents where filed and granted. As the patents were being filed the patent attorney for Bell Labs handling the filings made the observation that SuperMAN could packet switch voice very efficiently so he added a patent to that effect.

The packet voice patent is "Integrated Packetized Voice and Data Switching System" Patent Number: 4,872,160 Date of Patent: Oct 3, 1989 Some (but not all) related patents on the same "SuperMAN" system are 4,893,302 Jan 9, 1990 4,897,874 Jan 30, 1990 4,896,319 Jan 23, 1990 4,922,486 May 1, 1990 4,872,157 Oct 3, 1989 4,872,159 Oct 3, 1989 While the above dates are the dates of issue of the patents, it can be shown that work bagan in 1985 or 1986. (As an aside, the "SuperMAN" architecture seems to bear strong resemblances to Fibre Channel.) There were at about the same time several patents applied for using "fast packet" technology (i.e., omega fabrics and the like). Some of these also included packet voice. Also, David Vlack and I authored a book on the topic. The reference is W. Lidinsky, D. Vlack, "Perspectives on Packetized Voice and Data Communications", IEEE Press, 1991, ISBN 0-87942-233-5 The book describes packet voice issues and includes a number of papers on the subject. Some of these papers show prior art dating back to the mid-1980s and earlier.

Schulzrinne" Cc: rem-conf@es.net, glenn.parsons@bnr.ca Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Content-Description: cc:Mail note part Henning, Help me understand what you mean when you say G.721 is "depreciated". In an administrative action, G.721 has been replaced with G.726, an identical encoding. This encoding is still widely used in the store-and-forward voice processing industry as a good quality, low computation algorithm. draft-ema-vpim-00.txt is the hopefully proposed standard replacement for RFC 1911 and clarifies several byte-orderings, nibble packing ambiguities in the G.726 standard, and re-registers the audio/32kbadpcm mime content-type as G.726. (VPIM also refined the definition of Image/Tiff to better conform existing practice of the FAX board vendors) Are you suggesting that VPIM should use GSM, LD-CELP (G.728), or some other telco-grade algorithm rather than ADPCM? I have not been following the AVT work closely. (Please retain my address in the CClist) What encodings are being used in AVT that would be a suitable alternative? Greg V. ______________________________ Reply Separator _________________________________ Subject: Voice mail MIME type Author: "Henning G. Schulzrinne" at P_Internet_mail Date: 9/17/96 12:06 PM I note with some disappointment that RFC 1911 specifies the deprecated G.721 32 kb/s data type as the default type of voice mail storage. (It's even a registered MIME type, the only other audio MIME type beyond audio/basic.) ITU specifically no longer considers this recommendation "in force". In terms of complexity and performance for this particular task, there seem to be encodings which are superior in terms of complexity, performance and availability of source code. I realize that RFC 1911 is experimental; I'd hope that should this move to the standards track, some coordination with AVT might help. -- Henning Schulzrinne email: schulzrinne@cs.columbia.edu Dept. of Computer Science phone: +1 212 939-7042 Columbia University fax: +1 212 666-0140 New York, NY 10027 URL: http://www.cs.columbia.edu/~hgs From rem-conf-request@es.net Wed Sep 18 12:39:19 1996 Received: from dirty.research.bell-labs.com by osi-west.es.net with ESnet SMTP (PP); Wed, 18 Sep 1996 09:38:38 -0700 Received: from research.research.bell-labs.com by dirty; Wed Sep 18 12:36:34 EDT 1996 Received: from allegra.tempo.att.com by research; Wed Sep 18 12:30:47 EDT 1996 Received: from phero (phero.tempo.att.com) by allegra.tempo.att.com; id AA05669; Wed, 18 Sep 96 12:30:46 EDT Received: by phero; id AA08253; Wed, 18 Sep 96 12:30:43 EDT Date: Wed, 18 Sep 96 12:30:43 EDT From: slo@research.bell-labs.com (W.

Steven Lo I ran into this when trying to compile the RTPtools. It looks like there is a problem with the system header file "netinet/in.h". The build procedure I ended up using for the RTPtools was to use a version of the header file that was supplied with the RTPtools for SunOS 4.x machines, and the standard header file for Solaris 2.5 machines. I suggest you get the RTPtools and have a look at that header file.

Anecdote employs the concept of surrogate media (such as sketches), and surrogate scene (such as a design sketch of a screen). Both can be used to simulate the execution of the scenario and can serve as the specification of the data to be created. Anecdote allows authors to choose >from different authoring styles to construct the framework and helps them to create the final application seamlessly. We will show these functional capabilities by demonstrating some actual applications. --------------------------------------- This seminar will be broadcast on the Internet MBONE.

Regards, Kathy Westergaard Connectix Technical Support Frequently Asked Questions and Answers: Why is Connectix doing an Open Beta with the Grayscale QuickCam Driver for Windows NT? Many customers have requested a driver for the Grayscale QuickCam under Windows NT. In fact, we promised to have the driver available in July. Our QA department is very confident that this driver is stable. However, we would like to get it to a wider audience to insure this stability. Since Windows NT is a new operating system for us to support, we want to start slowly. The Technical Support staff is in training and will be ready to support Windows NT fully in the coming weeks. When will the Grayscale QuickCam Driver be released? We hope to release it officially in September. What does the Installer include? The installer includes all files necessary to use the Grayscale QuickCam with a Video for Windows compatible application under the Windows NT operating system. We do not include a Windows NT version of QuickPICT or QuickMovie, they are still in development. Users will need to have an application that runs under Windows NT (such as Premiere, CUSEEME, VIDCAP, etc.) Will this driver work with the Color QuickCam? No, this driver is designed for the grayscale QuickCam only! It will not support the Color QuickCam. We are investigating development of a Color QuickCam driver for Windows NT but do not have a schedule or a release date at this time. What Technical Support is available for the Open beta? Connectix will not support this Open Beta release through our standard telephone, electronic mail or online service support systems. Connectix will support the final release of the Windows NT Driver for the Grayscale QuickCam when it is released. If the user would like to report a problem with the installer or the driver, please send mail to: thunder@connectix.com. Again, this email address can not be used for support issues. Can I use VideoPhone with this driver under Windows NT? No, the current version of VideoPhone, 1.1.2 , does not work under Windows NT. Connectix is working on the problem and a future release of VideoPhone will support Windows NT. At 09:23 AM 9/26/96 -0700, you wrote: > > >---------- >From: Michael R.

Although we have many projects on the go, I am currently concentrating on one concerned with practical strategies for deploying ATM. I am in the process of collecting case studies on ATM - do you have any that I could have? Is there anyone else who has any ATM case studies and would like to be featured in our publication? It is from a global perspective so any country would be of interest. If you can fax me some, my fax no. is (UK) 01727 868848. I am also particularly interested in Telemedicine and would be grateful if you know of anyone I could contact about information on this. NB Please see attached. I look forward to hearing from you.

The initiative is the brainchild of Judy Estrin, co-founder of startup Precept Software Inc., a company that develops corporate-focused products using the multicast technology, where data, audio, video and multimedia are broadcast across the network to several addresses at once rather than a single address, thus conserving network bandwidth. The industry recently received a big boost when Microsoft recently announced its NetShow IP multicasting product. Multicasting, while just starting to attract the attention of corporate users, is still "a niche market," according to Tim Sloane, an analyst at the Aberdeen Group, a technology consulting firm in Boston. "Because the infrastructure doesn't support multicasting, applications aren't written to support it," he said. However, as the infrastructure becomes more ubiquitous, companies will increasingly seek out multicasting solutions for things like training videos and any application where data must be transmitted to a number of different points simultaneously. Estrin, who was also a co-founder of Network Computing Devices, said the group is not set up to create standards or establish technical directives for the IP multicast market. The architecture has already been created with the Internet Engineering Task Force's M-BONE multicasting backbone. Rather, she said, "We're really looking at those places where we can solve real business problems." The group will also be a place where customers can give the vendors feedback. The initiative will be managed by Stardust Technologies Inc., another startup, and will have its first meeting on Oct. 3, at which it will establish specific priorities for action. Other charter members, all of whom paid $25,000 to be part of the initiative, include Bay Networks, Cabletron, FTP Software, Intel, Silicon Graphics, StarBurst Communications, Sun Microsystems, 3Com, Vivo Software, White Pine Software and Xerox Parc. --Jeff Sweat InformationWeek http://techweb.cmp.com/iw [a search of these pages revealed no restrictions on duplication] all the best, Don -- Don Brutzman Naval Postgraduate School, Code UW/Br Root 200 work 408.656.2149 Monterey California 93943-5000 USA fax 408.656.3679 Virtual worlds/underwater robots/Internet http://www.stl.nps.navy.mil/~brutzman From rem-conf-request@es.net Mon Sep 30 15:10:08 1996 Received: from nobozo.CS.Berkeley.EDU by osi-west.es.net with ESnet SMTP (PP); Mon, 30 Sep 1996 12:09:32 -0700 Received: from sockeye (sockeye.CS.Berkeley.EDU [128.32.36.74]) by nobozo.CS.Berkeley.EDU (8.6.10/8.6.3) with SMTP id MAA18440 for ; Mon, 30 Sep 1996 12:09:32 -0700 Date: Mon, 30 Sep 1996 12:09:32 -0700 Message-Id: <199609301909.MAA18440@nobozo.CS.Berkeley.EDU> X-Sender: jerrlyn@nobozo.CS.Berkeley.EDU X-Mailer: Windows Eudora Version 2.1.1 Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" To: rem-conf@es.net From: Jerrlyn Iwata Subject: [Reminder] U.C.
