Embodiment Construction

[0022] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0023] First, the configuration of an information processing apparatus according to an embodiment of the present invention is explained with reference to FIGS. 1 and 2 . This information processing device may be, for example, a notebook computer 10 .

[0024] FIG. 1 is a perspective view of a notebook computer 10, showing that the display unit of the notebook computer 10 is opened. The computer 10 includes a main body 11 and a display unit 12 . The display unit 12 includes a display device consisting of a liquid crystal display (LCD) 17 whose display screen is located substantially at the center of the display unit 12 .

[0025] The display unit 12 is provided on the main body 11 in such a manner as to be rotatable between its open position and closed position. The main body 11 includes a thin box-shaped case. On the upper surface of the main body 11 are provi...

Abstract

A video reproduction application program (201) monitors whether or not blend processing for superimposing one of two images on the other is executed, and executes all decode processings (normal decode processings), when the blend processing is not executed. On the other hand, when the blend processing is executed, a specific processing is executed in which decoding of a color component is omitted from decode processing for decoding the images to be subjected to the blend processing. As a result, the load on the system is reduced.

Description

technical field [0001] The present invention relates to a decoding technique of a moving image stream applicable to an information processing device such as a personal computer. Background technique [0002] In recent years, personal computers having audio / video (AV) functions similar to AV devices such as digital versatile disc players and televisions have spread. This type of personal computer employs a software decoder that decodes a compression-coded moving image stream with software. This software enables compression-encoded moving image streams to be decoded by a processor (CPU) without providing special hardware. [0003] Further, recently, H.264 / AVC (Advanced Video Coding) has attracted attention as a next-generation moving image compression coding technology. The H.264 / AVC standard can perform compression encoding more efficiently than conventional compression encoding techniques such as MPEG2 and MPEG4. Thus, the load on the proce...
