Abstract

According to one embodiment, an information processing apparatus having a decoder to decode encoded streaming data to be displayed to form a picture including a plurality of blocks comprises a filtering unit (213) for filtering the decoded streaming data to reduce distortion of the block with respect to each picture, a detecting unit (211) for detecting a size of the picture to be displayed, and a simplifying unit (212) for simplifying the filtering by the filtering unit in response to the size of the picture detected by the detecting unit.

Description

technical field [0001] One embodiment of the present invention relates to an information processing apparatus, such as a personal computer, having a decoder that decodes encoded stream data to be displayed to form a picture including a plurality of blocks. Background technique [0002] In recent years, personal computers equipped with audio and visual (also called "AV") functions have become common, similar to AV equipment such as digital versatile disc (also called "DVD") players or televisions. [0003] This type of personal computer includes a software decoder that decodes compressed and encoded moving picture stream data by software. Using this software decoder enables decoding of compressed and encoded stream data by a central processing unit (also referred to as "CPU") without additionally providing dedicated hardware. [0004] Recently, attention has been paid to the H.264 / AVC standard, which is an acronym for Advanced Video Coding, as a next-generation technology fo...
