Re: [AVTCORE] New Version Notification for draft-westerlund-avtcore-rtp-payload-registry-00.txt

Hi Roni,

I agree there are some uncertainty if the Media Type registy structure at IANA will be updated as we are relying on future actions.

As you note independently if one start from RFC 8088, RFC 4588, or RFC 6838 if one has an RTP payload format one will arrive at sufficient instructions for the registration requirements for a framed type over RTP in the media type registry. One will however not do that for the RTP payload type registry in all those cases as only RFC 8088 really talks about this. .

Cheers

Magnus

Hi Magnus,
I agree that it make sense to close the RTP Payload Type registry. The media type registry has in the notes the following sentence “additional  procedures for registering media types for transfer via RTP can be found in [RFC4855]” . This sentence still applies except for the registration in the RTP payload type registry, for example the need for SDP procedure. This is for the case when registering RTP payload not via the IETF.
The comment is if the media type registry will be updated based on work in the Mediaman WG

Hi AVTCORE,

I have now submitted my very short draft that tries to clean up the situation around the RTP Payload Type registry. Please review and I think if people agree to this adminstrative action we should go on an adopt this as a WG item.

Cheers

Abstract:

   It has been observed that specifications of new RTP payload formats
   often forget to register themselves in the IANA regsitry "RTP Payload
   Formats Media Types".  In practice this has no real impact.  One
   reason is that the Media Types registry is the crucial regsistry to
   register any Media Type to establish the media type used to
   identified the format in various signalling usage.

   To resolve this sitaution this document performs the following.
   First it updates the registry to include known RTP payload formats at
   the time of writing.  Then it closes the IANA Registry for RTP
   Payload formats Media Types for future registration.  Beyond
   instructing IANA to close this registry the instructions to authors
   in RFC 8088 are updated that registration is no longer required in
   the closed registry.
