PURPOSE: This invention provides a data transmitter, a data receiver, a medium capable of corresponding to a plurality of encoding methods by transmitting a decoding method together with encoded video data and audio data. CONSTITUTION: 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).
