Abstract: An encoding method includes applying a search range constraint on a search range of a block in a current frame, and encoding the block in the current frame with pixel information in a reference frame according to inter prediction performed based on the search range of the block in the current frame, wherein a resolution of the current frame is different from a resolution of the reference frame.

Abstract: A method or apparatus of configuring a multi-channel coding device for use as a single-channel coding device is provided. The multi-channel coding device reconfigured as a single-channel coding device performs encoding or decoding of the pixels for a first color channel while substituting the pixels of a second color channel with predetermined (e.g., fixed) values. The reconfigured coding device may output reconstructed pixels of the first color channel but not reconstructed pixels of the second color channel.

Abstract: A method and apparatus for processing transform coefficients for a video coder or encoder is disclosed in the present invention. Embodiments according to the present invention reduce the storage requirement for sign bit hiding (SBH), improve the parallelism of SBH processing or simplify parity checking. Partial quantized transform coefficients (QTCs) of a transform block may be processed before all QTCs of the transform block are received. Zero and non-zero QTCs of a scan block may be processed concurrently and the QTCs of multiple scan blocks in a transform block may also be processed concurrently when computing cost function for SBH compensation. The range for searching for a value-modification QTC may be less than the scan block to be processed. Parity checking on QTCs may be based on least significant bits (LSBs) of all QTCs or all non-zero QTCs of a scan block.

Abstract: A method of binarizing an input symbol using a hybrid Truncated Rice/k-th order exp-Golomb binarization scheme with a Rice Parameter includes: determining a threshold; comparing the input symbol with the threshold; constructing a codeword using a Truncated Rice (TR) binarization process for the input symbol when a comparison result belongs to a first type of comparison result; and constructing a codeword with an initial prefix and a suffix for the input symbol when the comparison result belongs to a second type of comparison result; wherein the suffix is constructed using an exp-Golomb binarization process.
