This is a question which affects the design of the Media gateway control protocol. What information must be passed to the MG so it knows which media streams have to be synchronized? Is it sufficient that the MG knows which streams are flowing over the same user connection, or does the relationship have to be specified on a per-stream basis. I know that H.245 allows the latter, but I am considering the possibility of a Termination in a multimedia context, which binds together multiple H.245 Logical Channels. Under that circumstance, can the MG use rules to know that, for instance, audio and video are synchronized but data flows independently?
