Abstract
This disclosure describes techniques useful in the encoding and/or decoding of video data of a video sequence. In general, this disclosure sets forth scanning techniques useful in the context of sub-band coding, which may improve the level of compression that can be achieved by entropy coding following sub-band coding. In one example, a method of encoding video data of a video sequence comprises sub-band encoding the video data to generate a plurality of sub-bands, scanning each of the sub-bands from two-dimensional blocks into one-dimensional vectors based on scan orders defined for each of the sub-bands, and entropy encoding each of the scanned sub-bands.
