Patent ID: 8625668

Claim:
An information processing apparatus which decodes a compressed and encoded video stream, comprising: means for selectively generating one of an intra prediction image and an inter prediction image based on an encoding mode of at least one decoding object from the video stream; means for generating a residual error decoded image based on a quantization parameter of the decoding object from the video stream; means for generating a decoded image by adding (1) the selected one of the intra prediction image and the inter prediction image and (2) the residual error decoded image generated by the means for generating the residual error decoding image; means for applying a deblocking filter process for reducing a block distortion onto the decoded image generated by the residual error adding means; means for extracting information, the information being at least one of (i) information on a quantization parameter and (ii) information on the encoding mode of the decoding object from the video stream; means for determining whether or not the filter process is skipped based on the extracted information; and means for selectively skipping the filter process on the basis of a result provided by the means for determining; wherein the means for determining whether or not the filter process is skipped is based on a power supply being used by the information processing apparatus, where the filter process is performed when a commercial power supply driving is used, and the filter process is skipped based on a remaining battery level when power is supplied by a battery.
