Its also partly also addressing the discussion we had on "switched" and "composed" by listing the interaction between the MaxCaptures value and the number of captures in the MCC. Hopefully that gives a framework for further discussions. 7.2.1.1. Maximum Number of Captures within a MCC The Maximum Number of Captures MCC attribute indicates the maximum number of individual captures that may appear in a Capture Encoding at a time. It may be used to derive how the Single Media Captures within the MCC are composed / switched with regards to space and time. <<>> Max Captures MAY be set to one so that only content related to one of the sources are shown in the MCC Capture Encoding at a time or it may be set to any value up to the total number of Source Media Captures in the MCC. << Thread-Topic: IETF#89: CLUE Data Channel - Next Step Thread-Index: Ac84stqWg0jHh/1aTnG2LUuaAasKJw== Date: Wed, 5 Mar 2014 20:38:24 +0000 Message-ID: <7594FB04B1934943A5C02806D1A2204B1D1CFD69@ESESSMB209.ericsson.se> Accept-Language: en-US Content-Language: en-GB X-MS-Has-Attach: X-MS-TNEF-Correlator: Content-Type: multipart/alternative;

Hi data channel lovers,

Today we agreed to adopt DECP for the CLUE Data Channel (CDC).

(Note that we did NOT prevent usage of draft-eyzak, if the mechanism g= ets done in MMUSIC).

(We also agreed that there needs to be A way to identity that a call c= an use CLUE, but that is NOT the topic of this e-mail - please start a sepa= rate thread if you want to discuss that).

As time has been allocated for the CDC also on Friday, I intend to use= that time to discuss the issue regarding who is responsible for sending DA= TA_CHANNEL_OPEN.


First we need to decide if we want to specify who is responsible, or w= hether we’ll specify procedures when both endpoints send DCO.

My suggestion is that we do specify that one of the endpoints is respo= nsible.

Second, if we agree to the suggestion above, we need to decide which e= ndpoint is responsible for sending DCO. Alternatives are e.g. offerer, answ= erer, DTLS client and DTLS server. Note that this is separate from which en= dpoint establishes the SCTP association, and how the DTLS roles are determined - those procedures are defined in th= e sctp-sdp draft.

Also, we do need to describe what happens if both endpoint still sends= DCO. It would be considered an error case, and we could e.g. say that the = endpoint responsible for sending DCO would have to reset the stream/channel= created by the other endpoint.

Regards,

Christer

Here's a first stab at some text to stimulate some discussions. "The participant info attribute allows a provider to associate participant information with the capture source. When used in an individual capture it indicates that the captured content (e.g. video/audio/text etc.) as opposed to the actual media streams is generated from the entity described. How the generated content relates to the entity described in the participant info is dependent on media type and and the presentation attribute. For example: - a video capture with participant info would indicate that the video contains a picture of the entity associated with the information provided. - a video capture with participant info and the presentation attribute would indicate that the presentation video is associated with the participant but could contain any video content. - a text capture with participant info would indicate that the text is generated from the actual participant. - a text capture with participant info and the presentation attribute would indicate that the text is associated with the participant but could contain any text content."

[Duckworth, Mark] I suggest modifying these first two bullets: o When MaxCaptures is set to <=3D 1 and the number of captures in the MCC i= s greater than 1 (or not specified) this is a switched case. Zero or 1 capt= ure may be switched into the capture encoding.

[Duckworth, Mark] It sounds like these two paragraphs above apply not only = for the value 2, but more generally to any value >=3D2. Is that your inten= t? Also I suggest including in the above two bullets the case where the number= of captures in the MCC is not specified. Or we could write it as separate= bullets like this: o When MaxCaptures is set to <=3D 2 (or any number greater than 2) and the = number of captures in the MCC is not specified this is a switched and compo= sed case. The capture encoding may contain purely switched sources (i.e. <= =3D2 allows for 1 source on its own), or may contain composed and switched = sources (i.e. a composition of 2 sources switched between the sources). o When MaxCaptures is set to =3D 2 (or any number greater than 2) and the n= umber of captures in the MCC is not specified this is a composed case, and = may also be switched. =20 > o When MaxCaptures is set to <=3D to the number of captures in the MCC th= is > is a switched and composed case.

The text says the relationship is dependent on the presentation attribute, but not how. AFAICT I could make a new definition where the a participant attached to a presentation capture means that the participant is shown in the presentation, and that would be equally compatible with the text. ISTM that more text is required to actually specify the relationships.

Some (maybe all) of these algorithms for determining which end does the open may be difficult for applications to apply. In particular I'm thinking about an RTCWEB browser app. It *may* have access to info about whether it is the "even" or "odd" end, but maybe not.

Then it will use that channel to send advertisements and receive configurations. In the normal case, each will then receive an open. It would use that channel to receive advertisements and send configure messages. Or, we could just let each side send an open. If one side receives and open before sending one, then it won't send its own - both will use that one. If an endpoint receives an open after sending its own, it will ack that. At that point it has two CLUE channels. Both sides agree that if they have two clue channels, then they only use the one with the smaller stream ID, and send a reset on the one with the larger stream id. This does mean that any messages sent on the stream that is reset will be ignored. (That can happen if messages are sent immediately after the open, before the ack is received.)

Hi Paul,

Perhaps it would be tricky for an rtcweb app to figure out its DTLS ro= le, but it WOULD know whether it is offerer or answerer.

Some (maybe all) of these algorithms for determining which end does the open may be difficult for applications to apply. In particular I'm

It could figure that out by doing an experiment - opening a channel and then discovering its stream id. But that is silly.

I doubt it will have access to whether it is DTLS client or server. It
*might* be able to determine if it is offerer or answerer (of the first O/A in which the SCTP m-line appears. But this also seems tricky to
figure out. (It will likely have to scan every SDP sent or received,
looking for the SCTP m-line.)

Another alternative I'll try again is for each end to send an open *if* it wants to be an advertiser. Then it will use that channel to send
advertisements and receive configurations. In the normal case, each will then receive an open. It would use that channel to receive
advertisements and send configure messages.

Or, we could just let each side send an open. If one side receives and

they have two clue channels, then they only use the one with the smaller stream ID, and send a reset on the one with the larger stream id. This
does mean that any messages sent on the stream that is reset will be
ignored. (That can happen if messages are sent immediately after the
open, before the ack is received.)

Either of these symmetric ones are easy to implement in any environment.

Hi,

 

Based on the discussions in London, I’ve submi= tted a new version (-04) of draft-holmberg-clue-data-channel.

 

The draft now assumes that we will use the WebRTC Da= ta Channel (that’s what it’s called at the moment…), and = DCEP. There is a note regarding the usage of Richard’s draft, dependi= ng on the progress of the draft in MMUSIC.

 

In London we also agreed to WG adopt the draft, so t= his is the version I intend to submit as draft-ietf-clue-00, as soon as the= chairs give me a go ahead :)

 

Thanks to everyone that have given input and comment= s so far – both on the list and in the meetings! J

 

Regards,

 

Christer

I do have comments on this version, but IMO they don't impact adoption - they can be addressed either before or after. I want to talk to mary before initiating adoption. Section 3.2: I think this section could be weakened, to make DCEP the mechanism of last resort to establish the CLUE data channel, while *allowing* some other (currently unspecified) mechanism to preempt that. For instance: In the absence of some other mechanism, a CLUE entity MUST use the Data Channel Establishment Protocol (DCEP) [I-D.ietf-rtcweb- data-channel], in order to open a CLUE Data Channel. (This document does not define any other mechanism for establishing the CLUE channel, but one may be defined in the future.) Section 3.3.2: The usage of SCTP for the CLUE Data Channel ensures reliable transport of CLUE protocol [I-D.presta-clue-protocol] messages. NOTE: [I-D.ietf-rtcweb-data-channel] requires the support of the partial reliability extension defined in [RFC3758]. This is not needed for a CLUE Data Channel, as messages are required to always be sent reliably. [I-D.ietf-rtcweb-data-channel] also mandates support of the limited retransmission policy defined in [I-D.tuexen-tsvwg-sctp-prpolicies]. I think you need to be stronger here, and say that the parital reliability and limited retransmission policies MUST NOT be used. And when using DCEP, this is governed by the DCEP OPEN message parameters. I when opening the CLUE channel the Channel Type MUST be DATA_CHANNEL_RELIABLE. But this probably belongs in section 4.1. Section 4.1: I wonder if we want to include a version number in the protool name, just as another level of future-proofing. Section 4.2: This is a little vague about which of the pair of streams is reset. Section 7.2 of draft-jesup-rtcweb-data-protocol-04 says more about this. (Though it has some editorial issues.) ISTM that should either be referenced or copied here. Section 4.3: This section (and maybe others) refers to "the offerer". I don't think this is very clear. I think it would be helpful to define a new term (role) (e.g. Master) that identifies which end of the session is responsible for maintaining the association. It could be the end that sends the first offer that mentions the SCTP m-line in the clue group, or it could be more complicated. But regardless, it is defined in one place, and other places just reference that term, rather than something confusing like "offerer". Section 5.2: Where did you get this proto value??? According to draft-ietf-mmusic-sctp-sdp-06 it should be DTLS/SCTP. Section 5.4: In an offer, the offerer MUST NOT insert more than one "m=" line describing an SCTPoDTLS association to be used to realize a CLUE Data Channel. I think this is a little strong. I think we can say that the clue group must contain exactly one DTLS/SCTP m-line. Potentially there could be others that aren't in the clue group - they aren't our concern. I think it would be helpful to discuss the use of a=setup and a=connection here. (and in 5.5.) These may also provide a basis for defining which end takes future responsibility for maintaining the association. (BUT, these also apply to DTLS. draft-ietf-mmusic-sdp-mux-attributes-01 says that these attributes must be the same across a bundle. This constrains things.)

Well, comedia also talks about the offer and the answerer, for TCP. HAVING SAID THAT, I actually think this section belongs in the sctp-sdp dra= ft.

What do you mean by "clue group"? Do you mean BUNDLE group? Note that I am NOT saying one can only use one DTLS/SCTP m- line.

Does it do so when referring to some past o/a? I know it talks about the *current* offerer and answerer. That is fine.

Section 6 of the sctp-sdp draft does talk about the setup and connection at= tributes (it basically referes to TCP), so we can reference that. 6. The Setup and Connection Attributes and Association Management The use of the 'setup' and 'connection' attributes in the context of an SCTP association is identical to the use of these attributes in the context of a TCP connection. That is, SCTP endpoints MUST follow the rules in Sections 4 and 5 of RFC 4145 [RFC4145] when it comes to the use of the 'setup' and 'connection' attributes in offer/answer [RFC3264] exchanges. The management of an SCTP association is identical to the management of a TCP connection. That is, SCTP endpoints MUST follow the rules in Section 6 of RFC 4145 [RFC4145] to manage SCTP associations. Whether to use the SCTP ordered or unordered delivery service is up to the applications using the SCTP association.

It may not be very clear in the spec, though. I don't know, though that seems plausible. But my understanding was that what you were talking about is the sender of the offer that first introduced the sctp m-line. And that this role wouldn't be changed by future offers coming in the other direction. Maybe that isn't what you meant. But if so then again it seems unclear to me. > ----------------- > >>>> I think it would be helpful to discuss the use of a=setup and >>>> a=connection here. (and in 5.5.)

ISTM the implications need to be thought through, and then there *might* be a need to write something somewhere - not sure where. Here are a couple of issues that come to mind: - a bundle is created with some DTLS/RTP m-lines. Later, there is desire to add the DTLS/SCTP to the bundle. This will be a *new* SCTP association, but using the *existing* DTLS connection. So what is the a=connection attribute set to? And must it be the same for all the m-lines in the bundle? (That currently seems to be required.) If set to 'new', won't that force renegotiation of the DTLS, including possibly a new IP address? - if an error occurs on the SCTP association, but not on the DTLS connection, what does one do to recover? One might want to reinitialize the association, but how does one signal that? Offering a=connection:new would be one way, but it has all the same problems in the previous case. I realize these don't belong in CLUE docs. Where do they belong? I guess in the mmusic wg, but wrt what draft?

DTLS is only used for the RTP key exchange, isn't it? I checked 5763, and see that a=connection MUST NOT be used for DTLS/SRTP, though a=setup is used. I'm no expert, but I don't think there is any difference. The DTLS setup still needs to be done. It would simplify things if that isn't so. > In general, the SDP attribute considerations for BUNDLE shall be described in Suhas' draft. OK.

It isn't evident to me that the issues with bundle belong in that draft. Maybe in Suhas' draft, though this seems to be of a different character from the other things it deals with.

If > you want something more normative we could remove the "For example". Yeah, I don't believe in specification by example. :-) IMO it is a bit dicey to base this distinction on the type of capture. I'm more comfortable with an explicit syntactic indication of the distinction, such as proposed by Roberta.

You only know what it is for when an endpoint tries to do a DCEP open. All that the SDP offer/answer says with m= DTLS/SCTP and SCTPMAP=WebRTC datachannel is that the device wants to establish a DTLS/SCTP association with DCEP. It could use DCEP to establish protocol: "foo", "bar" or "CLUE". The association could be used for anything.

I think ultimately that the use of CLUE will depend on: 1. Usage of the session attribute GROUP indicating CLUE. 2. Specification of m-line for DTLS/SCTP association 3. Specification of a=mid indicating that the above m-line is part of the CLUE group 4. Specification of a=sctpmap indication "WebRTC datachannel" 5. Establishment of the DTLS/SCTP association 6. A successful DCEP open indicating the use of CLUE. So unless your draft specifies the use of the CLUE group then I don't think it is enough. If an endpoint wants to signal its intention to use CLUE via an SDP Offer then it has to do steps 1 to 4. You only have a "CLUE data channel" after steps 1-6.

Title : CLUE Protocol Data Channel Author : Christer Holmberg Filename : draft-ietf-clue-datachannel-00.txt Pages : 12 Date : 2014-03-20 Abstract: This document defines how to use the WebRTC Data Channel mechanism, together with the Data Channel Establishment Protocol (DCEP) in order to establish a data channel, referred to as CLUE Data Channel, for transporting CLUE protocol messages between two CLUE entities. The document defines the SCTP considerations specific to a CLUE Data Channel, the SDP offer/answer procedures for negotiating the establishment of, and the DCEP procedures for opening, a CLUE Data Channel. Details and procedures associated with the CLUE protocol are outside the scope of this document.

IIUC it is legal to have an a=group attribute without any identification-tags (mids), so we can use that to indicate *support* for CLUE even when not *using* CLUE. Based on that, here is a proposal: - SIP UAs that *support* CLUE MUST include one a=group:clue attribute in all SDP offers. - when a SIP UA that *supports* CLUE receives an offer containing an a=group:clue attribute, it MUST include a=group:clue in the answer. - SIP UAs that want to *use* CLUE SHOULD include a DTLS/SCTP m-line in offers, and reference it in the a=group:clue line. - if a SIP UA that wants to *use* CLUE receives an offer with a DTLS/SCTP m-line referenced from an a=group:clue attribute, it SHOULD accept the DTLS/SCTP m-line. - (more rules for using DCEP to set up the channel once the association is available) I'm leaving a little wiggle room above with the SHOULDs. For instance, it would be possible to do the first O/A with DTLS/SCTP, or one could wait for an indication that the other side supports CLUE before offering the DTLS/SCTP. A more interesting case: suppose the initial offer contained the clue group and offered the DTLS/SCTP, but the answer failed to indicate support for clue. Then subsequent offers could indicate clue support via the group, but not take the expense of offering the DTLS/SCTP. If, at some later time, a change occurs (e.g., a transfer) and a subsequent answer indicates support for clue, then another offer with the DTLS/SCTP can be made.

I need to think a little more about this.

I think in Londo= n we agreed that a single item in the new Global CSE List would consist of = a set of one or more CSEs.  We don’t want to include direct refe= rences to Media Captures.  If I’m remembering correctly, then in= section 18 we should remove this part:

<xs:element name=3D"captureIDREF" type=3D"xs:IDRE= F"

minOccurs=3D"0" maxOccurs=3D"unb= ounded"/>

 

I think there is a typo in the first sentence:

“<globalCaptureEntry> represe= nts a set of captures of the same media time...”

should be:

“<glo= balCaptureEntry> represents a set of captures of the same media *type*..= .”

and then I suggest change to cl= arify it is built from CSEs:

“<= globalCaptureEntry> represents a set of Capture Scene Entries of the sam= e media *type*...”

 

I’m in process of adding “Global CSE= List” to the framework document.

The current specification of the data model is compatible with the following statement: "If the point of capture is not specified, it means the consumer should not assume anything about the spatial location of the capturing device." Indeed, when describing a media capture, you have two possibilities (for the "choice" implementation): - if a capture is not spatially definable, it will not have any within its description and it will have a tag set to true. - otherwise (spatially definable capture), at least the capture point should be provided within the tag. Other information, like the line of capture point and the captured area, are optional. I think that John shares my view. Does it sound to you (all)?

In my presentation in London I tried to highlight commonalities when dealing with "content lists" in simultaneous sets, multiple content captures and global capture entries. I proposed to use for global capture entries the same content format of simultaneous sets and multiple content captures: "The content can be specified in terms of: 1.A list of (homogeneous) media capture identifiers 2.A list of (homogeneous) capture Scene Entry identifiers (used as shortcuts)" As far as I remember, there were no objections to that. It does not seem to be in contrast with discussion on the mailing list. Is there any reason why we should not include references to media captures within GCEs?

Hi Mark,

there is of course a typo in the definition, sorry.
In my presentation in London I tried to highlight commonalities when dealing with "content lists" in simultaneous sets, multiple content captures and global capture entries.
I proposed to use for global capture entries the same content format of simultaneous sets and multiple content captures:

"The content can be specified in terms of:
1.A list of (homogeneous) media capture identifiers
2.A list of (homogeneous) capture Scene Entry identifiers (used as shortcuts)"

As far as I remember, there were no objections to that.
It does not seem to be in contrast with discussion on the mailing list.
Is there any reason why we should not include references to media captures within GCEs?

Roberta

I think in London we agreed that a single item in the new Global CSE List would consist of a set of one or more CSEs.  We don’t want to include direct references to Media Captures.  If I’m remembering correctly, then in section 18 we should remove this part:

<xs:element name="captureIDREF" type="xs:IDREF"

minOccurs="0" maxOccurs="unbounded"/>

 

I think there is a typo in the first sentence:

“<globalCaptureEntry> represents a set of captures of the same media time...”

should be:

“<globalCaptureEntry> represents a set of captures of the same media *type*...”

and then I suggest change to clarify it is built from CSEs:

“<globalCaptureEntry> represents a set of Capture Scene Entries of the same media *type*...”

 

I’m in process of adding “Global CSE List” to the framework document.

 

Regards,

Mark

I think Christian shares this view. I also disagree with this from section 10.4: "Captures are spatially definible when it is possible to provide at least the coordinates of the device position within the telepresence room of origin." I suggest changing it to: "Captures are spatially definable when it is possible to provide the coordinates of either the device position or the area of capture within= the telepresence room of origin." The intent (in the framework, at least) was to allow a provider to specify = "area of capture" but not specify "point of capture" for any particular med= ia capture. I think we unintentionally lost this possibility when we moved= some attribute details from the framework to the data model several revisi= ons ago. One example scenario where this makes sense is in an advertisement from an = MCU that is constructing MCCs for its own scene, and will fill it by compos= ing and/or switching captures from other endpoints. The MCU can specify "a= rea of capture" using "no scale" coordinates (e.g. to maintain consistent l= eft-to-right relationship), but in this case a "point of capture" is not us= eful, not meaningful, and should not be required.

I will change the definitions provided in the data model accordingly. For the case you have proposed, the ADV could be the following: capture scene A: captures coming from room A capture scene B: captures coming from room B capture scene C: captures coming from room C capture scene D: MCC A (from room A's captures) - to be rendered on the left, MCC B (from room B's captures) - to be rendered on the centre, MCC C (from room C's capture) - to be rendered on the right where the "to be rendered" information are represented by means of the within the tag associated to the MCCs.

I have a little trouble with this too, though it may be that I don't conceptualize this correctly. We have area of capture, but that is a planar region. I keep wanting to think of that as an "area of display" that is ideal to render the capture. But to use that, I need to know which side of the display should be the front. Without a capture point, I don't know that. I suspect that there is an implicit assumption that the "front" of the area of capture will always be the side that puts the smallest X coordinate to the left of the larger X coordinate. I don't think we should assume such things.

Hi Mark,

there is of course a typo in the definition, sorry.
In my presentati= on in London I tried to highlight commonalities when dealing with "con= tent lists" in simultaneous sets, multiple content captures and global= capture entries.
I proposed to use for global capture entries the same = content format of simultaneous sets and multiple content captures:

&= quot;The content can be specified in terms of:
1.A list of (homogeneous)= media capture identifiers
2.A list of (homogeneous) capture Scene Entry= identifiers (used as shortcuts)"

As far as I remember, there w= ere no objections to that.
It does not seem to be in contrast with discu= ssion on the mailing list.
Is there any reason why we should not include= references to media captures within GCEs?

[Duckworth, Mark] It means the captures within the scene have some spatial = relation, and the capturePoint is either not known or not applicable. For = composed video captures I think the capturePoint would be not applicable, b= ecause there is no single capture point. >=20 > I have a little trouble with this too, though it may be that I don't > conceptualize this correctly. >=20 > We have area of capture, but that is a planar region.

Witho= ut a > capture point, I don't know that. [Duckworth, Mark] Yes, I think you do know that because the capture area ha= s named coordinates bottomLeft, bottomRight, etc. If the camera was locate= d at the back of the room, then the left X coordinate would be greater than= the right X coordinate. Maybe this is an assumption that the left and rig= ht here are from the point of view of the camera, but I think that is easy = to make explicit in the data model. This is a little odd, given the statem= ent "X increases from Camera-Left to Camera-Right", but if you have cameras= pointing in opposite directions within the same scene then one of them has= to be reversed with respect to the coordinate system. >=20 > I suspect that there is an implicit assumption that the "front" of the ar= ea of > capture will always be the side that puts the smallest X coordinate to th= e left > of the larger X coordinate. I don't think we should assume such things. [Duckworth, Mark] Don't have to assume it if we understand the named coord= inates of capture area as I suggest. The front is the side where the viewe= r would see the named left coordinates to the left of the named right coord= inates, regardless of the X values. >=20 > Thanks, > Paul >=20 > > Duckworth, Mark wrote: > >> From: Roberta Presta [mailto:roberta.presta@unina.it] > >>> > >>> For the case you have proposed, the ADV could be the following: > >>> > >>> capture scene A: captures coming from room A capture scene B: > >>> captures coming from room B capture scene C: captures coming from > >>> room C > > > > Three quite independent captures...

Maybe this is an assumption that the left and right here are from the point of view of the camera, but I think that is easy to make explicit in the data model. This is a little odd, given the statement "X increases from Camera-Left to Camera-Right", but if you have cameras pointing in opposite directions within the same scene then one of them has to be reversed with respect to the coordinate system. OK, I accept that. (I didn't have in my head that the corners were named that way.) >> I suspect that there is an implicit assumption that the "front" of the area of >> capture will always be the side that puts the smallest X coordinate to the left >> of the larger X coordinate.

The front is the side where the viewer would see the named left coordinates to the left of the named right coordinates, regardless of the X values. OK.

Here is a new se= ction I’m adding to the framework.  Please send any comments or = suggestions.

7.3.3. Gl= obal Capture Scene Entry List

 = ;

An Advertisement can include an optional gl= obal Capture Scene Entry list, for each media type.  Each item in this= list is a set of one or more Capture Scene Entries.  Each set of CSEs= in the list is a suggestion from the Provider to the Consumer for which CS= Es represent the entire advertisement, across multiple scenes.  The Pr= ovider can include multiple sets, to accommodate different Consumers with v= arying capability to receive multiple encodings.  This is very similar= to how each CSE represents a particular scene.

 

As an example, suppose an= advertisement has three scenes, and each scene has three CSEs, ranging fro= m one to three video captures in each CSE.  The provider is advertisin= g a total of nine video captures across three scenes.  The provider ca= n use the Global CSE list to suggest alternatives for consumers that can't = receive all nine video captures.  For accommodating a consumer that wa= nts to receive three video captures, a provider might suggest a single CSE = with three captures and nothing from the other two scenes.  Or a provi= der might suggest three different CSEs, one from each scene, with a single = video capture in each.  The choice of how to make these suggestions in= the Global CSE list for what represents the entire advertisement is up to = the provider.

 

Some additional rules:

&= #8226;           &nb= sp; The ordering of items (sets of CSEs) in the global CSE list is not impo= rtant.

•    &n= bsp;        The ordering of CSEs within = each set is not important.

• =             The Prov= ider must be capable of encoding and sending all Captures within the CSEs o= f a given set simultaneously.

I also added a statement in 7.3 saying a CSE has an advertisement = unique identity.

 

I also plan to add an example in 12.3 for Global CSE Lis= t, taken from my IETF89 slides.

We are now in the end game - working to *finish* all of these documents. Based on the London meeting there is work for everybody to do. The interim should be for addressing issues that have arisen while doing that. IMO we should target to have new revisions of at least the signaling, data model, and protocol well in advance of the interim. And for people to have reviewed those. Then the meeting time can be spent on thrashing out remaining issues.

Hi,

I drafted an initial definition for a g.sip.clue media feature tag.

I didn’t write a draft, because I assume I’d end up in an= existing draft.

I am not sure whether we want to use “clue” in the media = feature tag name, or whether e.g. “telepresence” would be more = appropriate.

Regards,

Christer

I agree we are using to convey information that are not related to any physical space coordinates. They are instead purely "rendering suggestions" - coordinates in a virtual space, the typical case where to use the "no scale" scale value, as Mark said. They are two slightly different concepts ("real" spatial information and rendering information) that we express by means of the same element. Due to the maybe misleading name, I am wondering if we need to make more explicit such a "multiple" use of the element or if it is better to separate the two aspects. What is your feeling about it?

ISTM that one describes physical space (three-dimensional) and the other describes a mathematical concept, instantiated on a visual display. Mixing them is inherently confusing. (Arguments that the mathematical concept is a "space" do not move me -- everything in math is sometimes described as a "space".) I seriously fear that we've only scratched the surface of the confusion we've uncovered. I do understand that bikeshedding can prevent progress until it's too late to consider the important issues. But keeping physical space distinct from mathematical "space" strikes me as an important issue. > They are distinguished by the "scale" attribute of . I doubt this. I remember only "millimeters", "unknown", and "noscale". I can imagine folks using "noscale" for three-dimensional space. Also, I find "scale" a rather strange way to disambiguate physical from mathematical space... -- John Leslie From nobody Fri Mar 28 11:32:12 2014 Return-Path: X-Original-To: clue@ietfa.amsl.com Delivered-To: clue@ietfa.amsl.com Received: from localhost (ietfa.amsl.com [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 1F2481A0959 for ; Fri, 28 Mar 2014 11:32:09 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -1.219 X-Spam-Level: X-Spam-Status: No, score=-1.219 tagged_above=-999 required=5 tests=[BAYES_00=-1.9, HTML_MESSAGE=0.001, J_CHICKENPOX_34=0.6, RCVD_IN_DNSWL_LOW=-0.7, SPF_NEUTRAL=0.779, UNPARSEABLE_RELAY=0.001] autolearn=no Received: from mail.ietf.org ([4.31.198.44]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id ESv16GfilSbw for ; Fri, 28 Mar 2014 11:32:06 -0700 (PDT) Received: from mail1.bemta7.messagelabs.com (mail1.bemta7.messagelabs.com [216.82.254.112]) by ietfa.amsl.com (Postfix) with ESMTP id 6DB2D1A095D for ; Fri, 28 Mar 2014 11:32:05 -0700 (PDT) Received: from [216.82.254.20:52296] by server-16.bemta-7.messagelabs.com id 68/6A-27701-320C5335; Fri, 28 Mar 2014 18:32:03 +0000 X-Env-Sender: Mark.Duckworth@polycom.com X-Msg-Ref: server-15.tower-47.messagelabs.com!1396031521!3713789!2 X-Originating-IP: [140.242.64.158] X-StarScan-Received: X-StarScan-Version: 6.11.1; banners=-,-,- X-VirusChecked: Checked Received: (qmail 998 invoked from network); 28 Mar 2014 18:32:02 -0000 Received: from crpehubprd01.polycom.com (HELO crpehubprd02.polycom.com) (140.242.64.158) by server-15.tower-47.messagelabs.com with AES128-SHA encrypted SMTP; 28 Mar 2014 18:32:02 -0000 Received: from CRPMBOXPRD07.polycom.com ([fe80::91fc:8a0f:5258:aff0]) by crpehubprd02.polycom.com ([fe80::5efe:10.236.0.154%12]) with mapi; Fri, 28 Mar 2014 11:31:23 -0700 From: "Duckworth, Mark" To: Christer Holmberg , "clue@ietf.org" Date: Fri, 28 Mar 2014 11:31:21 -0700 Thread-Topic: [clue] Initial proposal for definition of media feature tag g.sip.clue Thread-Index: Ac9KiO0GuNdECbboR5q2VF3GWurWVQAKrnEw Message-ID: <49E45C59CA48264997FEBFB29B6BC2D617ACF1B662@CRPMBOXPRD07.polycom.com> References: <7594FB04B1934943A5C02806D1A2204B1D267240@ESESSMB209.ericsson.se> In-Reply-To: <7594FB04B1934943A5C02806D1A2204B1D267240@ESESSMB209.ericsson.se> Accept-Language: en-US Content-Language: en-US X-MS-Has-Attach: X-MS-TNEF-Correlator: acceptlanguage: en-US Content-Type: multipart/alternative; boundary="_000_49E45C59CA48264997FEBFB29B6BC2D617ACF1B662CRPMBOXPRD07p_" MIME-Version: 1.0 Archived-At: http://mailarchive.ietf.org/arch/msg/clue/XEcUChuwF2tPb0-7dZKTQr2PEAg Subject: Re: [clue] Initial proposal for definition of media feature tag g.sip.clue X-BeenThere: clue@ietf.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: CLUE - ControLling mUltiple streams for TElepresence List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 28 Mar 2014 18:32:09 -0000 --_000_49E45C59CA48264997FEBFB29B6BC2D617ACF1B662CRPMBOXPRD07p_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable I think sip.clue is more appropriate than sip.telepresence. sip.clue is sp= ecific to the CLUE protocol, which is what we want, right?

As we are using uni-directional streams, one could even use separate BUNDLE= groups per direction. But, that should not cause any problems either. But, I don't think we shall mandate support of BUNDLE by CLUE entities. It = sould be optional to support, and optional to use.

The discussions around the use of spatial information for audio captures just seemed to die out without any real conclusion. As John has alluded to the use of the spatial attributes for audio is problematic. We don't seem to have any text in the framework discussing this or forbidding the use of the spatial information for audio. With regards to the video related spatial information I didn't realize that there was deep seated confusion over the use of the attributes. From a previous email: where the "to be rendered" information are represented by means of the within the tag associated to the MCCs. has always bothered me, because it is a two-dimensional quantity, while we interact in three-dimensional space. I suppose I should have objected to including it at all in ; but until now I thought we understood it to be defining space in a plane within our three-dimensional interaction space (and therefore a three-dimensional space from to the ). I thought of the being a quadrilateral on a plane in 3D space, i.e. a 2D area. The and were points in this 3D space giving the relationship between the capture device and the . This was in order to allow the Renderer to perform what ever geometric corrections it needed to do in order to provide an optimal rendering of the image on a screen i.e. quadrilateral on a plane. In the case where the image has been through a device that performs the geometric corrections etc. (e.g. an MCU) the resultant image still represents an quadrilateral on a plane (albeit with Y=0). In terms of the and there would be "virtual" values for these as a result of any transformations applied to the image. I guess the assumption is that is would be meaningless to send these as no further transformation requiring these points would be required.

For me the "advertisement" is the CLUE message. So it seems strange to talk about CSEs representing the advertisement. Perhaps something like "... for which CSEs provide a complete representation of the simultaneous captures provided by the provider, across multiple scenes."? > > The Provider can include multiple sets, to accommodate different > Consumers with varying capability to receive multiple encodings. This > is very similar to how each CSE represents a particular scene. > [CNG] Is the GCSE about providing sets for multiple "encodings"? You can provide multiple encodings without GSEs. Isn't it about providing different sets of captures so that a receiver can best determine what the set of captures it wants based on the service it wants to provide. I.e. a consumer may only support three media streams (3 encodings) but these may be used in a number of ways. > As an example, suppose an advertisement has three scenes, and each > scene has three CSEs, ranging from one to three video captures in each > CSE.

"A CSE may be used in multiple sets." Otherwise its not clear whether this is allowed or not. Also I take it there's at most one CSE instance per SET. > > • The ordering of items (sets of CSEs) in the global CSE list is not > important. > > • The ordering of CSEs within each set is not important. > > • The Provider must be capable of encoding and sending all Captures > within the CSEs of a given set simultaneously. > [CNG] Do we need to add some text to the simultaneous set section of the framework indicating this? We should probably say something about the interaction. i.e. If a GCSE set is included should the provider actually need to provide a STS? Sendings CSEs in a STS indicates the those CSE/captures may be used simultaneously. There appears to be alot of overlap with the GCSE in this respect. > ============================== > > I also added a statement in 7.3 saying a CSE has an advertisement > unique identity. > > I also plan to add an example in 12.3 for Global CSE List, taken from > my IETF89 slides. > [CNG] OK > > Mark > > > > _______________________________________________ > clue mailing list > clue@ietf.org > https://www.ietf.org/mailman/listinfo/clue From nobody Mon Mar 31 18:30:52 2014 Return-Path: X-Original-To: clue@ietfa.amsl.com Delivered-To: clue@ietfa.amsl.com Received: from localhost (ietfa.amsl.com [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 6D2C81A6FC0 for ; Mon, 31 Mar 2014 18:30:48 -0700 (PDT) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -0.001 X-Spam-Level: X-Spam-Status: No, score=-0.001 tagged_above=-999 required=5 tests=[BAYES_20=-0.001] autolearn=ham Received: from mail.ietf.org ([4.31.198.44]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 0ntUUld9-2KW for ; Mon, 31 Mar 2014 18:30:46 -0700 (PDT) Received: from cserver5.myshophosting.com (cserver5.myshophosting.com [175.107.161.1]) by ietfa.amsl.com (Postfix) with ESMTP id C16051A6FBE for ; Mon, 31 Mar 2014 18:30:45 -0700 (PDT) Received: from ppp118-209-197-202.lns20.mel6.internode.on.net ([118.209.197.202]:53188 helo=[127.0.0.1]) by cserver5.myshophosting.com with esmtpsa (TLSv1:DHE-RSA-AES128-SHA:128) (Exim 4.82) (envelope-from ) id 1WUnX8-0003B1-Vd; Tue, 01 Apr 2014 12:30:35 +1100 Message-ID: <533A16BA.40707@nteczone.com> Date: Tue, 01 Apr 2014 12:30:34 +1100 From: Christian Groves User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:24.0) Gecko/20100101 Thunderbird/24.4.0 MIME-Version: 1.0 To: Paul Kyzivat , "clue@ietf.org" References: <5318809E.2030204@nteczone.com> <5318AE5E.4050404@alum.mit.edu> <5318B0C9.1050603@nteczone.com> <5318B48E.3090300@alum.mit.edu> <53290C9B.6090106@nteczone.com> <5329F3FF.7090606@alum.mit.edu> In-Reply-To: <5329F3FF.7090606@alum.mit.edu> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit X-AntiAbuse: This header was added to track abuse, please include it with any abuse report X-AntiAbuse: Primary Hostname - cserver5.myshophosting.com X-AntiAbuse: Original Domain - ietf.org X-AntiAbuse: Originator/Caller UID/GID - [47 12] / [47 12] X-AntiAbuse: Sender Address Domain - nteczone.com X-Get-Message-Sender-Via: cserver5.myshophosting.com: authenticated_id: christian.groves@nteczone.com X-Source: X-Source-Args: X-Source-Dir: Archived-At: http://mailarchive.ietf.org/arch/msg/clue/qjNYaTGJTm7QdLbe1WEtXhl7Mpo Subject: Re: [clue] Participant info/type followup X-BeenThere: clue@ietf.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: CLUE - ControLling mUltiple streams for TElepresence List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 01 Apr 2014 01:30:48 -0000 Hello Paul, all, If we follow the approach that there is a specific indicating of whether the participant information is based on an explicit indication then I would suggest the following text for the framework: Clause 7.1.11 Participant information (Under the 1st paragraph) The participant information contains an explicit indication of whether it relates to a participant contained in the capture, from a participants capture device or both. For example a video camera may capture an image containing the participant, or a participant may send a video capture with a presentation that does not depict the participant. Something similar would be needed under participant type. Thoughts?

I think the more "interesting" issue is one of the ones raised at the London meeting, that is using CLUE in an RTCWeb environment that uses bi-directional streams. BTW for future design team meeting I don't know if it could be made at 7.00am CDT? That is 11pm for me. 8.30amCDT means we would finish at 1.30am for me.
