摘要： The present invention relates to a simplified pipeline for Sample Adaptive Offset (SAO) and Adaptive Loop Filtering (ALF) in the in-loop decoding of a video encoder and a video decoder. According to the present invention, filter parameter setting regions and filtering processing windows are aligned, to reduce the required amount of memory for parameter sets necessary for delayed filtering. This is preferably achieved by a displacement of the filter parameter setting regions with respect to LCU boundaries in at least one (preferably: vertical) or both vertical and horizontal directions.

摘要： The present invention relates to filtering of image data at first with a deblocking and then with an adaptive loop filter, suitable for the purpose of video coding and decoding. In order to reduce requirements to a memory on chip, used to buffer image lines necessary for filtering, the input signal for the adaptive loop filter is determined from among deblocked pixels, non-deblocked pixels and partially (horizontally only or vertically only) deblocked pixels. The adaptive loop filtering of a deblocked pixel may then apply the filter taps to already deblocked pixels and/or undeblocked pixels and/or partially deblocked pixels in accordance with the determination of the input signal. An advantage of the invention is reduction of the line memory necessary especially at the decoder for processing with both filters.

摘要： The present invention relates to coding of an image of a video sequence block wisely and, in particular, to coding of a block of samples, which may be chrominace or luminance samples, or samples of any colour space, by a pulse code modulation (PCM). After PCM coding, deblocking filtering may be applied. The deblocking filter may be selected for the present PCM coded block based on its noise and/or the noise of its adjacent block. The noise of the PCM coded block is indicated by a so-called PCM quantization parameter, which is also encoded in the bitstream.

摘要： The present invention relates to deblocking filtering, which may be advantageously applied for block-wise encoding and decoding of image or video signal. In particular, the present invention relates to automated decision on whether to apply or skip deblocking filtering for a block and to selection of the deblocking filter. The decision and/or selection is performed for predefined individual pixels based on the amount of quantization of the block the boundary of which is to be deblocked and on the amount of quantization of its neighboring block adjacent to the boundary, as well as on the position of the individual pixels.
