Abstract: A system and method for conveying information that is helpful for a network middlebox or a media player to decided which coded data units to forward or process within an RTP payload or a file format data unit in an easy-to-access manner. This mechanism can be used to provide indications of items such as redundant coded pictures, temporal level switching points, gradual decoding refresh access points, view identifiers, and view random access points. A middlebox and/or receiver can then use this information to determine whether certain coded data units need to be processed and/or transmitted.
