<P>PROBLEM TO BE SOLVED: To prevent increase of hardware and increase of the time required for processing. <P>SOLUTION: The decoder 1 comprises a reception time management function unit 6 which manages the scheduled reception start time of a signal received from each transmission side device, based on the transmission start time information and the length information of transmission time being notified to each transmission side device, a decoding system determination function unit 7 which determines a decoding system from the identification information of a transmission side device of a signal received at the scheduled reception start time, and a decoding function unit 8 which decodes a signal on the basis of the decoding system information. The reception time management function unit 6 completes the preparation of decoding of the decoding function unit 8 before the scheduled processing start time, by outputting the identification information of a transmission side device of a signal received at the scheduled reception start time to the decoding system determination function unit 7 prior to the scheduled processing start time of the decoding function unit 8. <P>COPYRIGHT: (C)2013,JPO&INPIT |
