Moving-picture coding device employing intra-frame coding and inter-frame coding

摘要

A device for coding moving pictures includes a coding unit for applying intra-frame coding or inter-frame coding to the of blocks dividing each frame of the moving pictures. The device further includes a refresh-operation-control unit for controlling the coding unit to carry out the intra-frame coding as a refresh operation at predetermined intervals. The refresh-operation-control unit reschedules the predetermined intervals when the coding unit applies the intra-frame coding during one of the predetermined intervals, such that a timing of the intra-frame coding during the one of the predetermined intervals marks a start of a next one of the predetermined intervals.
