摘要： PROBLEM TO BE SOLVED: To provide a dynamic image decoding apparatus having actualized reduction of load required for digital process of the dynamic image under the condition that deterioration in image quality is suppressed in the side of receiving and decoding the dynamic image.
SOLUTION: A video decoder application program 300 for reproducing a dynamic image stream encoded with the compression-encoding method by the system conforming to the specification MPEG-2 checks, in unit of slice, the number of skip macro-blocks in the B frame as the non-reference frame to determine whether it is equal to or larger than the predetermined number. When it is detected that the number of skip macro-blocks is equal to or larger than the predetermined number, reduction of load can be actualized by setting all macro-blocks other than the starting and ending macro-blocks within the slice to the skip macro-block.

摘要： PROBLEM TO BE SOLVED: To effectively simplify the processing of inter-prediction, to reduce a load and power consumption, and to satisfactorily perform decoding processing in real time. SOLUTION: In the case of decoding a compression-encoded moving image stream in a moving image decoding device, whether or not the processing of an inter-prediction part 106 should be simplified is decided based on encoding mode information in an inter-prediction saving decision part 110.

摘要： PROBLEM TO BE SOLVED: To provide an information processing apparatus capable of smoothly performing decoding of a moving picture stream without incurring remarkable image quality deterioration.
SOLUTION: A video reproduction application program 201 detects a present load amount of a computer 10. When the computer 10 is not in a high load state, the video reproduction application program 201 decodes a moving picture stream in an ordinary procedure. When the computer 10 reaches the high load state, the video reproduction application program 201 detects a block whose predicted error component is smaller than a prescribed value on the basis of a value of an orthogonal transform coefficient (DCT coefficient) included in each block. Then the video reproduction application program 201 skips performance of inverse orthogonal transform processing (inverse DCT processing) with respect to a detected block and performs processing of zeroing a prediction error signal of the detected block.
