Hi all, This is an updated version of the RTSP 2.0 ANNOUNCE draft. The draft has been discussed during the last IETF meeting, but the WG didn't find a conclusion yet. The draft argues for introducing semantics for two explicit RTSP server to client asynchronous notifications: - one for end-of-stream and - one for end-of-session. There is already some embedded end-of-session in RFC 2326bis but it is a bit hidden in REDIRECT. I'm still in favour of adding a new method to RTSP 2.0 (ANNOUNCE or any other name) that is used to convey these two asynchronous notifications. Any comment?
