ABSTRACT:
A data output apparatus generates and transmits a data stream in which content data coded by a default coding method and a decoding program for content data coded by a changeable coding method are multiplexed together. The decoding program is multiplexed on the data stream plural times repeatedly at predetermined intervals. A decoding apparatus receives the data stream transmitted by the data output apparatus, and acquires and installs the multiplexed decoding program. Until the decoding program is completely installed to be executable, the decoding apparatus decodes the content data by a decoding process corresponding to the default coding method. When the decoding program is completely installed, the decoding apparatus executes the decoding program and decodes the content data by a decoding process corresponding to the changeable coding method.
