Abstract:
Methods and devices for reconstructing coefficient levels from a bitstream of encoded video data for a coefficient group in a transform unit. Greater-than-one flags are encoded by grouping them into tuples and by encoding a tuple-based value that is a function of the greater-than-one flags within that tuple. The tuple-based value may permit the decoder to infer the greater-than-one flags in some cases, in which case they are not encoded in the bitstream.
