    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.

    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: An entropy decoding apparatus includes an entropy decoding circuit, a pre-fetch circuit, and a context pre-load buffer. The pre-fetch circuit pre-fetches at least one candidate context for entropy decoding of a part of an encoded bitstream of a frame before the entropy decoding circuit starts entropy decoding of the part of the encoded bitstream of the frame. The context pre-load buffer buffers the at least one candidate context. When a target context actually needed by entropy decoding of the part of the encoded bitstream of the frame is not available in the context pre-load buffer, the context pre-load buffer instructs the pre-fetch circuit to re-fetch the target context, and the entropy decoding circuit stalls entropy decoding of the part of the encoded bitstream of the frame.
