摘要

A transmitter (201) transmits a decoding method (107) generated by means of a decoding method generating means (203) together with encoded video data and audio data at the time of transmitting the video and audio data and, in a receiver (202), a decoding control means (111) decodes video data and audio data (115) by controlling a decoding means (208) based on a decoding method (113) received from a transmitter (201). Therefore, it is not required for the receiver (202) to hold all of a plurality of decoding methods in advance and for the transmitter (201) to encode video data and audio data in accordance with one of the decoding methods held by the receiver (202).
