INTRA-FRAME PREDICTION-BASED DECODING METHOD AND DECODING DEVICE

摘要

The embodiments of the present invention provide an intra-frame prediction-based decoding method and decoding device. The decoding method comprises: acquiring for a current prediction unit one or multiple split flags, a split shape flag, and a split direction flag from a compressed video image stream; splitting the current prediction unit ultimately into multiple square transform units or multiple rectangular transform units according to the acquired one or multiple split flags, split shape flag, and split direction flag; executing decoding process on each square transform unit of the ultimately split multiple square transform units or on each rectangular transform unit of the ultimately split multiple rectangular transform units.
