Abstract: A method and apparatus for video encoding or decoding used by a video encoder or decoder respectively. In one method, input data associated with a video sequence are received. A current sequence header for a current picture is determined. Whether the current sequence header corresponds to a first sequence header or a second sequence header is determined. If the current sequence header corresponds to the second sequence header, one or more syntax values of a syntax set associated with the first sequence header are assigned to corresponding one or more syntax values of the syntax set associated with the current sequence header. The current picture is then encoded or decoded according to the current sequence header.

Abstract: A data processing system includes a buffer, a design under checking (DUC), and a self-checking circuit. The buffer is used to buffer data generated from a source device. The DUC is used to perform a designated function upon data read from the buffer when operating under a normal mode. The self-checking circuit is used to apply logic functional checking to the DUC when the DUC operates under a self-checking mode. When the DUC operates under the self-checking mode, the buffer keeps buffering data generated from the source device.

Abstract: A method and apparatus for loop filter processing of reconstructed video data for a video coding system are disclosed. The system receives reconstructed video data for an image unit. The loop filter processing is applied to reconstructed pixels above a deblocking boundary of the current CTU. In order to reduce line buffer requirement and/or to reduce loop filter switching for image units, the sample adaptive offset (SAO) parameter boundary and spatial-loop-filter restricted boundary for the luma and chroma components are determined by global consideration. In one embodiment, the SAO parameter boundary and the spatial-loop-filter restricted boundary are aligned for the luma and chroma components respectively. In another embodiment, the SAO parameter boundary and the spatial-loop-filter restricted boundary for the luma and chroma components are all aligned.

Abstract: A video decoding method is used for decoding a multi-plane video bitstream. The multi-plane video bitstream includes a first video subset bitstream corresponding to a fundamental plane (FP) and at least one second video subset bitstream corresponding to at least one augmented plane (AP). The video decoding method includes decoding the first video subset bitstream, decoding the at least one second video subset bitstream, and performing resampling of one decoded FP frame to generate one resampled frame. Decoding the first video subset bitstream includes performing decoding of a first FP frame to generate a first decoded FP frame. Decoding the at least one second video subset bitstream includes performing decoding of a first AP frame to generate a first decoded AP frame. A processing time of performing decoding of the first FP frame overlaps a processing time of performing resampling of said one decoded FP frame.

Abstract: A decoding apparatus has an arithmetic decoder and a controller. A counter logic of the controller generates a first statistics result according to a first syntax element decoding result. A control logic of the controller instructs the arithmetic decoder to perform a first scan procedure at least once to generate the first syntax element decoding result of transform coefficients of a transform coefficient block, controls a repetition number of a second scan procedure based at least partly on the first statistics result, and instructs the arithmetic decoder to perform the second scan procedure at least once to generate a second syntax element decoding result of the transform coefficients. The first scan procedure decodes a first coded syntax element of one transform coefficient when performed by the arithmetic decoder once. The second scan procedure decodes a second coded syntax element of one transform coefficient when performed by the arithmetic decoder once.
