Abstract:
Disclosed is a method of decoding a luma transform and plurality of chroma transforms from a video bitstream. The chroma transforms contain chroma data for a single colour channel. The method determines a value of a luma transform skip flag for the luma transform indicating whether data of the luma transform is encoded in the video bitstream as a spatial domain representation. A value of a chroma transform skip flag is determined for a first chroma transform of the plurality of chroma transforms indicating whether the data of the chroma transform is encoded in the video bitstream as a spatial domain representation. The method decodes the luma transform according to the determined luma transform skip flag and the plurality of chroma transforms according to the determined chroma transform skip flag for the first chroma transform.

Claim (Index 1):
A method of inverse transforming a plurality of residual coefficient arrays from a video bitstream configured for a 4:2:2 format, the method comprising:\n decoding up to four luma residual coefficient arrays, wherein each luma residual coefficient array corresponds to one respective 4\u00d74 luma block of our 4\u00d74 luma blocks, of the four 4\u00d74 luma blocks collectively occupying an 8\u00d78 luma region; decoding, after the up to four luma residual coefficient arrays are decoded, up to two chroma residual coefficient arrays for a first chroma channel, wherein a first one of the chroma residual coefficient arrays for the first chroma channel corresponds to a 4\u00d74 chroma block associated with an upper portion of the 8\u00d78 luma region and a second one of the chroma residual coefficient arrays for the first chroma channel corresponds to a 4\u00d74 chroma block associated with a lower portion of the 8\u00d78 luma region and the second one of the chroma residual coefficient arrays for the first chroma channel is decoded consecutively after the first one of the chroma residual coefficient arrays for the first chroma channel is decoded and wherein the first one of the chroma residual coefficient arrays for the first chroma channel and the second one of the chroma residual coefficient arrays for the first chroma channel are decoded dependent on respective coded block flag values; decoding, after the up to two chroma residual coefficient arrays for the first chroma channel are decoded, up to two chroma residual coefficient arrays for a second chroma channel, wherein a first one of the chroma residual coefficient arrays for the second chroma channel corresponds to a 4\u00d74 chroma block associated with the upper portion of the 8\u00d78 luma region, and a second one of the chroma residual coefficient arrays for the second chroma channel corresponds to a 4\u00d74 chroma block associated with the lower portion of the 8\u00d78 luma region, and the second one of the chroma residual coefficient arrays for the second chroma channel is decoded consecutively after the first one of the chroma residual coefficient arrays for the second chroma channel is decoded wherein the first one of the chroma residual coefficient arrays for the second chroma channel and the second one of the chroma residual coefficient arrays for the second chroma channel are decoded dependent on respective coded block flag values; and applying a 4\u00d74 inverse transform to each of the decoded up to four luma residual coefficient arrays, each of the decoded up to two chroma residual coefficient arrays for the first chroma channel, and each of the decoded up to two chroma residual coefficient arrays for the second chroma channel.
