  • Patent number: 8244052
    Abstract: The present invention discloses the video coding method using image data skipping. Said method detects whether the encoded macro-block has to be skipped and terminated by a likelihood ratio test prior to mode decision. Therefore, the computation burden such as motion estimating and compensating can be properly eliminated. In one embodiment, the skipping likelihood ratio is composed of the encoded block and its predictions associated with the skipping displacement. While the decision threshold adapts according to the mode decision and detection statistics, the false detection and rate-distortion are substantially preserved.
