To provide a moving image decoder, with which a plurality of programs are simultaneously decoded and sent to a plurality of viewing devices by one device and the same program can be simultaneously sent to a plurality of viewing devices.

This device is composed of a demultiplexing means 19 for demultiplexing one or a plurality of program data selected by a selecting means 17, a plurality of decoding means 20-1,..., 20-n for decoding one or a plurality of program data demultiplexed by this demultiplexing means 19 and a plurality of interface means 21-1,..., 21-n for outputting the program data decoded by the respective decoding means 20-1,..., 20-n to viewing devices 18-1,..., 18-n and program data are demultiplexed from a received multiplexed signal 10, simultaneously and parallel decoded and outputted.
