Abstract: A system and method of decoding a sub-block of residual coefficients of a transform block from a video bitstream. The method comprises determining whether sign bit hiding is used for the sub-block, the determination based on a value of a transform skip flag determined for the sub-block and a value of a sign bit hiding flag associated with the sub-block; if sign bit hiding is not used, decoding a number of sign bits equal to a number of significant coefficients in the subblock; and decoding the sub-block by reconstructing the residual coefficients of the sub-block using the decoded sign bits.

Abstract: A method of de-blocking an edge of a block of samples of video data is disclosed. A first prediction mode is decoded for a first block of two adjacent blocks of video data, each of the blocks of video data including a primary color channel and at least one secondary color channel. A second prediction mode is decoded for a second block of the two adjacent blocks of video data. A boundary strength value is determined for a block of samples along an edge corresponding to a boundary between said first block of video data and said second block of video data. A weak de-blocking filter is applied to the block of data along said edge if the determined boundary strength value indicates that the first prediction mode is intra prediction and the second prediction mode is intra-block copy prediction. The weak de-blocking filter is different to a filter applied to a block determined to have two, adjacently located, intra prediction mode blocks.

Abstract: A method of encoding a portion of a video frame into a video bitstream, in which the portion of the video frame contains samples, take account the samples representing luminance levels according to an EOTF. The method determines a luminance of the portion of the video frame, and a desired (environment) luminance step size. The desired luminance step size represents a just noticeable difference (JND) determined according to the determined luminance and a predetermined ambient luminance, the desired luminance step size being greater than a luminance (transfer function) step size from the EOTF. The method then determines a quantisation parameter from the desired luminance step size and the luminance step size from the EOTF, the quantisation parameter being used for encoding the portion of the video frame, and then encodes encoding the portion of the video frame into the video bitstream according to the determined quantisation parameter.

Abstract: A plurality of display device profiles is decoded from a bitstream containing video data. A display device profile is selected by comparing at least a portion of the device information of the display device profiles with corresponding device information of the first display device. An image modification parameter set is selected from a plurality of image modification parameter sets according to the selected display device profile, the plurality of image modification parameter sets being decoded from the bitstream and each of the plurality of image modification parameter sets providing information regarding luminance mapping to be applied to one or more portions of the video data. At least a portion of the video data is displayed on the first display device from the bitstream of video data by applying the selected image modification parameter set to the portion of video data from the bitstream of video data.
