Abstract
When transmitting encoded video data and audio data, a transmitter 201 also transmits a decoding method 107 generated by decoding-method generation means 203. In the case of a receiver 202, decoding control means 111 controls decoding means 208 in accordance with a received decoding method 113 and thereby, decodes video data and audio data 115. Thus, it is unnecessary for the receiver 202 to previously prepare all of a plurality of decoding methods and the transmitter 201 does not need to encode video data or audio data in accordance with the decoding method owned by the receiver 202.
