Abstract: Aspects of the disclosure provide a method for merging compressed access units according to compression rates and/or positions of the respective compressed access units. The method can include receiving a sequence of compressed access units corresponding to a sequence of raw access units partitioned from an image or a video frame and corresponding to a sequence of memory spaces in a frame buffer, determining a merged access unit including at least two consecutive compressed access units based on compression rates and/or positions of the sequence of compressed access units. The merged access unit is to be stored in the frame buffer with a reduced gap between the at least two consecutive compressed access units compared with storing the at least two consecutive compressed access units in corresponding memory spaces in the sequence of memory spaces.

Abstract: A method and apparatus for video encoding to generate a partitioned bitstream without buffering transform coefficient and/or prediction data for subsequent coding units are disclosed. An encoder incorporating an embodiment according to the present invention receives first video parameters associated with a current coding unit, wherein no first video parameters associated with subsequent coding units are buffered. The encoder then encodes the first video parameters to generate a current first compressed data corresponding to the current coding unit. A first memory address in the first logic unit is determined and the encoder provides the current first compressed data at the first memory address in the first logic 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.

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.

Abstract: A data processing apparatus has a compressor and an output interface. The compressor receives an input multimedia data, and generates an output multimedia data according to the input multimedia data. The output interface packs the output multimedia data into an output bitstream, and outputs the output bitstream via a camera interface. The compressor adaptively adjusts a compression algorithm applied to the input multimedia data according to visibility of compression artifacts. By way of example, the camera interface may be a camera serial interface (CSI) standardized by a Mobile Industry Processor Interface (MIPI).
