SessionDependency was added when the layered video codec support was added. Check the annex on layered video in H.323. (Or AVC's from Intel on the subject)

Hello all!

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?
