Abstract
The claimed subject matter provides systems and/or methods that facilitate describing, communicating, utilizing, etc. a frame dependency structure in connection with real time video communication. For example, a protocol can be employed to communicate the dependency structure from a sender to a receiver. Moreover, a mechanism on a receiver side can detect frame(s) that will be rendered with artifacts if displayed due to previous frame loss; this mechanism can leverage receiver side knowledge concerning the dependency structure of the frames.
