<p>The invention relates to an encoding system for encoding input video data and to a decoding system for decoding encoded streams. Specifically, an encoded stream is accompanied in transmission so that ancillary data and information characteristic of the video data may not be lost after a number of repetitions of MPEG encoding and MPEG decoding. An MPEG encoder extracts the ancillary data attached to input video data, and transmits the extracted ancillary data together with the encoded stream by inserting the ancillary data as Ancillary_data() in the encoded stream. An MPEG decoder extracts the ancillary data from the encoded stream, and attaches the extracted ancillary data to baseband video data generated by MPEG decoding.</p> |
