Patent ID: 7653128

Claim:
An information processing apparatus for decoding compression-coded video data, comprising: at least one decode means for decoding the compression-coded video data; supply control means for controlling the supply of the compression-coded video data to the decode means; and control means for controlling processing executed by the supply control means and the decode means, wherein the control means determines the order of decoding processing performed by the decode means so that, among pictures contained in a decoding processing unit for the decoding processing performed by the decode means, I-pictures and P-pictures are decoded before B-pictures, the control means selects pictures to be output from the decode means from among the pictures contained in the decoding processing unit on the basis of a playback speed instruction provided by playback speed instruction means, and when the picture at the head of the decoding processing unit is a B-picture among decoded pictures output from the decode means, the control means controls the decode means so that a decode start timing at which the decode means starts decoding and a display output timing at which the decode means starts outputting the decoded pictures are displaced from each other by a first predetermined number of pictures.
