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.
