I have a question about a new field in H.245: SessionDependency INTEGER (1..255) OPTIONAL
What is it used for? Does it hold a SessionId value? Does anybody have (or remember the # of ) the related TD about it?
Thank you, Orit Levin Orit,
I believe this field is used for the layered codec model with H.263+. This is from AVC-1125: "The sessionDependency field is set by the MC to indicate when a session is dependent on another session for meaningful decoding of the its data." I believe sessionDependency identifies the session which has the base layer or enhancement layer for the video (if this is a video session). Hope this helps.
