摘要： A system includes a data storage configured to store a model human visual system, an input module configured to receive an original picture in a video sequence and to receive a reference picture, and a processor. The processor is configured to create a pixel map of the original picture using the model human visual system. A first layer is determined from the pixel map. A weighting map is determined from a motion compensated difference between the original picture and the reference picture. A processed picture is then determined from the original picture using the weighting map and the first layer.

摘要： Encoding a video signal including pictures includes generating perceptual representations based on the pictures. Reference pictures are selected and motion vectors are generated based on the perceptual representations and the reference pictures. The motion vectors and pointers for the reference pictures are provided in an encoded video signal. Decoding may include receiving pointers for reference pictures and motion vectors based on perceptual representations of the reference pictures. The decoding of the pictures in the encoded video signal may include selecting reference pictures using the pointers and determining predicted pictures, based on the motion vectors and the selected reference pictures. The decoding may include generating reconstructed pictures from the predicted pictures and the residual pictures.

摘要： In a system for processing and displaying a DVD-video data stream, a system for decoding and processing a subpicture data stream. The subpicture data stream comprises a subpicture pixel data stream and a subpicture display control data stream. The subpicture display control data stream preferably comprises one or more display control commands, one or more of which include subpicture display control information. The system comprises at least one processing unit for processing software programmed to perform at least some subpicture data stream decoding and subpicture display control command execution. In addition, the system further comprises a subpicture hardware unit configured to receive the subpicture pixel data stream, subpicture control information extracted from a subpicture display control command executed by said at least one processing unit, and subpicture display control commands not executed by said at least one processing unit. After receiving the information, the subpicture hardware unit generates subpicture display information, which is presented to a DVD video display unit. The subpicture-display information preferably comprises pixel color and contrast information.
