Abstract
A method for decoding of a video bitstream including receiving coded data for a 2N×2N coding unit (CU) from the video bitstream, selecting one or more first codewords according to whether asymmetric motion partition is disabled or enabled, selecting one or more second codewords when a size of the 2N×2N CU is equal to a smallest CU size, wherein none of the second codewords corresponds to INTER N×N partition when N is 4, determining a CU structure for the 2N×2N CU from the video bitstream using the first codewords or the second codewords, and decoding the video bitstream using the CU structure. A corresponding method for encoding a 2N×2N coding unit of video data is also disclosed.
