<P>PROBLEM TO BE SOLVED: To manage a reproduction-side processing time when a multichannel voice signal is encoded with variable compression ratio. <P>SOLUTION: Predicting circuits 13D1, 13D2, and 15D1 to 15D4 and buffer selectors 14D1, 14D2, and 16D1 to 16D4 perform predictive encoding of a 6-channel voice signal. A DTS generator 17 generates decoding time stamp information showing the read timing of compressed data from a decoding-side input buffer 22a according to the amounts of predictively encoded data by channels and a formatting circuit 19 formats the data into a packet having a packet header including the decoding time stamp information and user data including the compressed data. <P>COPYRIGHT: (C)2004,JPO |
