Abstract: A device for decoding video data determines, for a residual block of video data encoded using a transform skip mode, a value for a first neighboring coefficient of a coefficient currently being decoded; determines a value for a second neighboring coefficient of the coefficient currently being decoded; determines a context offset for the coefficient currently being decoded based on the value for the first neighboring coefficient and the value for the second neighboring coefficient; and decodes a value for the coefficient currently being decoded based on the determined context offset.

Abstract: A video encoder and video decoder may apply deblocking filtering to edges of chroma blocks that are encoded and/or decoded using an intra block copy mode. In one example, the video encoder and video decoder may code one or more chroma blocks of the video data using an intra block copy mode, and apply deblocking filtering to one or more edges of a basic processing unit for the one or more coded chroma blocks of the video data, wherein the basic processing unit has a size of M×N.
