摘要:
The present invention relates to a reproduction device, a reproduction method, and a program that enable the maintenance of real-time production of encoded video signals while suppressing a visually bad impression. As shown in FIG. 3, load reduction processes executed by a decoder include the following six types of processes: that is, a deblocking filter off process, a B picture simple motion compensation (MC) process, a P picture simple motion compensation (MC) process, a non-store picture frame skip process, a store picture frame skip process, and an only I picture reduction process. These six types of load reduction processes gradually reduce loads (that is, computation amounts) required for decoding by being added one at a time for execution in the described order. The present invention can apply to a decoder of an H.264/AVC, for example.
