摘要： The coding device of the present invention includes: a decoder for decoding a first stream signal in which a first video stream including a first video stream information generated by coding a first video signal and a first audio stream including a first audio stream information generated by coding a first audio signal are multiplexed; and a re-encoder for generating, based on the decoded first stream signal, a second video stream including a second video stream information having a bit rate lower than the first video stream information and a second audio stream including a second audio stream information having a bit rate lower than the first audio stream information, and multiplexing the second video stream and the second audio stream to generate a second stream signal.

摘要： A signal transmission apparatus is provided for transmitting a plurality of pieces of encoded audio information encoded by the same encoding method via a digital interface to a signal reception apparatus, in which each of the plurality of pieces of encoded audio information has a sampling frequency of F or 1/2 x F. The apparatus comprises a data generating section for, based on one-frame data obtained by dividing the encoded audio information into frames, generating at least one block, and a data output section for outputting the at least one block generated by the data generating section to the digital interface. Each of the at least one block includes a body portion, and a header portion storing management information for managing data stored in the body portion.
