A reconstruction method comprising: obtaining () a region predictor for a current region of a picture based on a spatial prediction; obtaining () an information representative of a partitioning of the current region into sub-regions; reconstructing () at least one residual sub-region based on an intra prediction residual and an intra prediction mode and obtaining a reconstructed residual region from the at least one reconstructed residual sub-region, wherein all reference samples external to the current region used for reconstructing the at least one sub-region are set to zero before reconstructing the at least one residual sub-region; and, reconstructing () the current region based on the reconstructed residual region and on the region predictor by adding a final predictor obtained from the region predictor and the reconstructed residual region.

Spatial illumination compensation on large areas

A method comprising: obtaining () a syntax element associated with video data, wherein said syntax element specifies that a cross-color component transform process in which at least one second color component is transformed based on at least one first color component different from the second color component is to be applied to the video data as a post processing process following a decoding process to be applied to the video data.

Method and device for luma mapping with cross component scaling

Video content frequently seen in gaming content and having a higher probability of being coded in transform skip mode is coded separately from remaining portions of a video coding block before being combined with regular coded portions. This enables more efficient coding of video by reducing the switching between regular coding modes and transform skip modes. The regular coded portion and the transform skip coded portion are combined in an encoder. At a corresponding decoder, inverse operations occur, such that the transform skipped residual portions are decoded and the regularly coded portions are decoded before the portions are combined for a resultant decoded video block.
