摘要： In a block-based motion compensated system, coding noises may arise due to lossy operations. Adaptive loop filter (ALF) is a technique used to improve the quality. A pixel adaptive (PA) ALF method was developed that uses the Sum-modified Laplacian Measure (SLM) to classify pixels and applies a respective ALF filter to each pixel according to the SLM. While the PA ALF achieves better performance over a conventional single filter (SF) based ALF, the PA ALF causes higher complexity and consumes more power due to the high complexity and per-pixel filter switching. Accordingly region based ALF scheme is disclosed which allows adaptive filter selection on a region by region basis and does not require per-pixel filter switching. In one embodiment according to the present invention, a picture is divided into M×N regions. The region based ALF also allows region merging for the M×N regions to improve performance. In another aspect of the present invention, the optimal ALF design also takes into consideration of the system complexity by using rate-distortion-complexity optimization (RDCO). The RDCO technique is also applied to sample adaptive offset (SAO) design.

摘要： In one embodiment, there is provided a moving image decoder for decoding a compression-coded moving image stream. The decoder includes: a deblocking filter configured to perform deblocking filter processing on each of frames to be decoded; a load detector configured to detect a magnitude of internal processing loads occurring inside a video player, including a processing load for decoding; a determination module configured to determine whether to bypass the deblocking filter processing, depending on the magnitude of the internal processing loads. The deblocking filter is configured to bypass the deblocking filter processing, if the magnitude of the internal processing loads is bigger than a threshold value and a processing subject block of the frame is decoded using inter-view prediction.

摘要： A multi-core video decoder system has a syntax parser, a storage device, a plurality of video decoder cores and a control unit. The syntax parser performs syntax parsing upon an incoming encoded video bitstream to derive required information of each picture to be decoded. The storage device buffers the required information of each picture. The control unit controls the video decoder cores to load required information of a plurality of coding rows in a picture from the storage device and then decode the coding rows in the picture, respectively.
