Abstract
A multimedia coding and decoding system and method is presented that uses the specific prediction mode to signal supplemental information, e.g., metadata, while considering and providing trade offs between coding performance and metadata capacity. The prediction mode can be encoded according to a mode table that relates mode to bits and by considering coding impact. Start and stop codes can be used to signal the message, while various techniques of how to properly design the mode to bits tables are presented.
