CODE CONVERSION/TRANSMISSION METHOD AND APPARATUS FOR MOVING IMAGE DATA, AND CODE CONVERSION/RECEPTION METHOD AND APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for transmitting image data for suppressing, to a hardly noticeable level, a significant corruption of a decoded image at the recipient which includes been caused by a transmission error of encoded data.

SOLUTION: A code conversion/transmission apparatus being supplied with compressed encoded data and converting and outputting the data to a transmission path includes code converter/transmitters for outputting the encoded data input thereto and encoded data produced by re-encoding the encoded data input thereto, or outputting a plurality of encoded data comprising encoded data produced by separately re-encoding the encoded data input thereto, respectively, and transmitting the plurality of encoded data to at least one transmission path. At least a portion of the input encoded data input thereto and at least a portion of the re-encoded encoded data are transmitted to the transmission path.
