Abstract:
1. An image decoding apparatus for decoding at least a first coded bit stream into which header information of the H.263 coding scheme and image coded data encoded in the H.263 coding scheme are multiplexed, or for decoding a second coded bit stream into which header information of the MPEG-4 coding scheme and image coded data encoded in the MPEG-4 coding scheme are multiplexed, the image decoding apparatus comprising: a setter for setting image coded information to be used for decoding the received first coded bit stream according to a syntax of the second coded bit stream based on the image coded information included in the header information of the H.263 coding scheme; and a decoder for decoding image coded information included in the header information of the MPEG-4 coding scheme from the received second coded bit stream, wherein when the first coded bit stream is received, the received first coded bit stream is decoded according to the syntax of the second coded bit stream based on the image coded information set by the setter, and when the second coded bit stream is received, the received second coded bit stream is decoded according to the image coded information decoded by the decoder.
