    Abstract: A data processing apparatus has a compressor and an output interface. The compressor generates a compressed display data by compressing a display data according to a compression algorithm. The output interface records indication information in an output bitstream, and outputs the output bitstream via a display interface, wherein the output bitstream is derived from the compressed display data, and the indication information is set in response to the compression algorithm employed by the compressor. Another data processing apparatus has a de-compressor and an input interface. The de-compressor de-compresses a compressed display data derived from an input bitstream. The input interface receives the input bitstream via a display interface, parses indication information included in the input bitstream, and configures the de-compressor to employ a de-compression algorithm as indicated by the indication information.

    Abstract: Methods and apparatus of compression for pre-stitched pictures captured by multiple cameras of a panoramic video capture device are disclosed. At the encoder side, stitching information associated with a stitching process to form the pre-stitched pictures is used to encode a current block according to embodiments of the present invention, where the stitching information comprises calibration data, matching results, seam position, blending level, sensor data, or a combination thereof. In one embodiment, the stitching information corresponds to matching results associated with a projection process, and projection-based Inter prediction is used to encode the current block by projecting a reference block in a reference pre-stitched picture to coordinates of the current block. In another embodiment, the stitching information corresponds to seam information associated with seam detection, and seam-based Inter prediction is used to encode the current block by utilizing the seam information.

    Abstract: A method for storing data of an image frame into a frame buffer includes at least the following steps: dividing the image frame into a plurality of access units, each having at least one encoding unit, wherein each encoding unit is a unit for data compression; and performing the data compression upon each encoding unit of the image frame, and generating an output bitstream to the frame buffer based on a data compression result of the encoding unit. A processing result of each access unit includes each output bitstream of the at least one encoding unit included in the access unit; a plurality of processing results of the access units are stored in a plurality of storage spaces allocated in the frame buffer, respectively; and a size of each of the storage spaces is equal to a size of a corresponding access unit.

    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.
