<p>PROBLEM TO BE SOLVED: To realize decoding with less image quality deterioration in the case of tandem connection of decoders. SOLUTION: Each decoder that decodes a coding stream is provided with a decoding circuit 103 (110) that extracts information (picture type) relating to a coding function in past coding processing applied to the coding stream among coding streams and that decodes the coding stream on the basis of the information relating to the coding function, and provided with a multiplexer circuit 105 (111) that multiplexes the decoded video data and the information relating to the coding function and that transmits the multiplexed data.</p> |
