ENCODING DEVICE, ENCODING METHOD, DECODING DEVICE, DECODING METHOD, CODING SYSTEM AND CODING METHOD

摘要

The present invention relates to an encoding system for encoding input video data and a decoding system for decoding the encoded streams. More particularly, it proposes a system and method for sending the ancillary data added to video data and the information inherent to the video data together with encoded streams in such a way that they will not be lost even if MPEG encoding and MPEG decoding are repeated. The MPEG encoder extracts the ancillary data from the video data, inserts the extracted ancillary data into encoded streams as Ancillary_data, and thereby sends the ancillary data together with the encoded streams. The MPEG decoder extracts ancillary data from the encoded streams and adds the extracted ancillary data to the base-band video data generated by MPEG decoding.
