APPARATUS AND METHOD FOR IMAGE DATA CODING WITH ADDITIONAL DATA EMBEDDING

摘要

By taking advantage of the time delay arising from the buffer in an MPEG encoder, information concerning future bit rate is inserted at regular locations in the bit-stream. In consequence, a multiplexer or data inserter receives advance notice of opportunities to insert data into the bit-stream. Advance notice enables data to be drawn from secondary storage and to be formatted optimally. In both cases, the effective data-carrying capacity of the stream is increased.
