Abstract: Method and system of video decoding incorporating frame compression to reduce frame buffer size are disclosed. The method adjusts parameters of the frame compression according to decoder system information or syntax element in the video bitstream. The decoder system information may be selected from a group consisting of system status, system parameter and a combination of system status and system parameter. The decoder system information may include system bandwidth, frame buffer size, frame buffer status, system power consumption, and system processing load. The syntax element comprises reference frame indicator, initial picture QP (quantization parameter), picture type, and picture size. The adaptive frame compression may be applied to adjust compression ratio. Furthermore, the adaptive frame compression may be applied to a decoder for a scalable video coding system or a multi-layer video coding system.

Abstract: A data processing apparatus has a first compressor, a second compressor, a first output interface, and a second output interface. The first compressor performs compression upon a first portion of an input display data of a frame to generate a first compressed display data, wherein the compression performed upon the first portion of the input display data has a first compression configuration. The second compressor performs compression upon a second portion of the input display data of the frame to generate a second compressed display data, wherein the compression performed upon the second portion of the input display data has a second compression configuration. The first output interface transmits the first compressed display data over a first display port of a display interface. The second output interface transmits the second compressed display data over a second display port of the display inter face.

Abstract: A path planning method applied to a navigation device includes acquiring a two-dimensional depth map, transforming the two-dimensional depth map into a gray distribution map via statistics of pixel values on the two-dimensional depth map, computing a space matching map by arranging pixel counts on the gray distribution map, and computing a weighting value about each angle range of the space matching map in accordance with a distance from location of a pixel count to a reference point of the space matching map. The weighting value represents existential probability of an obstacle within the said angle range and a probable distance between the navigation device and the obstacle.

Abstract: A data processing apparatus includes a compressor and an output interface. The compressor generates a plurality of compressed pixel data groups by compressing pixel data of a plurality of pixels of a picture based on a pixel data grouping setting of the picture. The output interface packs the compressed pixel data groups into an output bitstream, records indication information in the output bitstream, and outputs the output bitstream via a display interface. The indication information is indicative of at least one boundary between consecutive compressed pixel data groups packed.
