INTRA PREDICTION MODE DERIVATION FOR CODING BLOCKS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18407090 titled 'INTRA PREDICTION MODE DERIVATION FOR CODING BLOCKS
The patent application discusses methods and an apparatus for video coding, specifically focusing on intra prediction modes in block coding.
- The apparatus includes processing circuitry that receives coded information of a current block in a current picture.
- The current block is coded with a first intra prediction mode that is different from a plurality of intra prediction modes, including DC mode, Planar mode, and angular intra prediction modes.
- A candidate block in the current picture coded by a different intra prediction mode is selected.
- If the candidate block is within a pre-defined region, a second intra prediction mode is derived from the plurality of intra prediction modes for the candidate block.
- The second intra prediction mode is associated with the current block and is used to select a transform for the current block and/or to construct a most probable mode (MPM) list for another block.

Original Abstract Submitted
Aspects of the disclosure include methods and an apparatus for video coding. The apparatus includes processing circuitry that receives coded information of a current block in a current picture. The current block is coded with a first intra prediction mode that is different from a plurality of intra prediction modes including a DC mode, a Planar mode, and angular intra prediction modes. A candidate block in the current picture coded by an intra prediction mode different from the plurality of intra prediction modes is selected. If the candidate block is located within a pre-defined region, a second intra prediction mode is derived from the plurality of intra prediction modes for the candidate block. The second intra prediction mode is associated with the current block and is used to select a transform for the current block and/or to construct a most probable mode (MPM) list for another block.
