Abstract
A method of processing media data received at a receiver over a bitstream having a standardized format that supports descriptors includes receiving at the receiver an extension descriptor that specifies a descriptor tag having a value within a prescribed tag value range, a descriptor length having a value within a prescribed length value range, at least one extension descriptor tag value that identifies a descriptor, and extension descriptor data associated with the identified descriptor. Responsive to the extension descriptor tag value, the identified descriptor and the extension descriptor data associated with the identified descriptor are employed to process the media data at the receiver.
