Abstract
The various implementations described herein include methods and systems for encoding and decoding video. In one aspect, a method of video decoding includes receiving video data comprising a plurality of blocks, including a first block, from a video bitstream, where the first block is encoded in one of a plurality of smooth modes. The method also includes identifying a set of reference samples for the first block and deriving a first prediction value for the first block, where the first prediction value is derived from a second prediction value, the second prediction value is derived without a division or shift operation, and a final step in deriving the first prediction value comprises a division or shift operation. The method further includes decoding the first block using the first prediction value.
