Patent ID: 8724708

Claim:
An image decoding device, comprising: a plurality of image decoding units connected in parallel and operable to perform decoding processing on an encoded first video signal which is segmented into a plurality of segments; and an allocation control unit operable to, using different methods in accordance with whether an error is detected, determine which of the image decoding units to allocate each of the segments, based on a data amount of each of the segments, so that periods of time required for processing by the image decoding units are substantially equal, and allocate one or more of the segments to each of the image decoding units based on the allocation which is determined, wherein, if an error is detected, the allocation control unit determines which of the image decoding units to allocate each of the segments to compensate for a reduced processing load of an image decoding unit to which a segment including the error is allocated occurring due to skipping of the segment including the error.
