摘要： A device includes a coder or a codec configured for interleaved image data utilizing diamond shaped blocks for motion estimation and/or motion compensation and utilizing square or orthogonal transforms of residual data. In various embodiments, the decoder may be configured, among others, to perform de-blocking on edges of the diamond shaped blocks and/or data padding at boundaries of the image data. Additionally a method is proposed in which at least one of a transform and quantization process to be applied to de-multiplexed data is modified. One application is to combine left and right stereoscopic images, interleaved in a checkerboard manner.

摘要： Improved video coding is described to encode video data within a sequence of video frames. To this end, at least a portion of a reference frame is encoded to include motion information associated with the portion of the reference frame. At least a portion of a predictable frame that includes video data predictively correlated to said portion of said reference frame is defined based on the motion information. At least said portion of the predictable frame is encoded without including corresponding motion information and including mode identifying data. The mode identifying data indicate that the encoded portion of the predictable frame can be directly derived using at least the motion information associated with the portion of the reference frame.

摘要： There are provided a method and apparatus for reusing available motion information as a motion estimation predictor for video encoding. The apparatus includes an encoder for encoding an image block by determining a motion estimation predictor for the image block using motion information previously generated from an element other than the encoder, and using the motion estimation predictor in a motion estimation process to generate a motion vector for the image block. The motion estimation predictor is used in place of at least one predictor otherwise used in the motion estimation process. The at least one predictor is any of a search window predictor, a temporal predictor, and a block type predictor.
