DECODING DEVICE, INFORMATION PROCESSING SYSTEM, AND DYNAMIC IMAGE RECORDING AND REPRODUCING SYSTEM

摘要

Disclosed is a decoding device comprising a plurality of decoding request units (10101,10112) which are provided to correspond to a plurality of bit streams and issue a frame decoding request in each frame period of the corresponding bit stream, a decoding unit (10103) which decodes the frame corresponding to the frame decoding request in a time-division cycle, an arbitration unit (10102) which arbitrates contention between frame decoding requests and notifies the decoding unit, and a selection unit (1010202) which selects one of the plurality of bit streams as the reference channel. The arbitration unit (10102) arbitrates so that a frame decoding request corresponding to the reference channel is allocated in a fixed manner to the reference cycle, which is the cycle corresponding to the frame period of the reference channel, and arbitrates so that a frame decoding request corresponding to the bit stream of a channel other than the reference channel is allocated to a cycle other than the reference cycle.
