VIDEO ENCODING/DECODING METHOD AND APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18431245 titled 'VIDEO ENCODING/DECODING METHOD AND APPARATUS
Simplified Explanation
The present disclosure provides a method and a device for encoding/decoding a video. The method for decoding a video includes deriving a most probable mode (MPM) list based on intra prediction modes of neighboring blocks adjacent to a current block. The method also includes generating prediction pixels using candidate modes in the MPM list or the intra prediction modes of the neighboring blocks, calculating the sum of absolute transformed difference (SATD) between the prediction pixels and reconstructed pixels, deriving a first intra prediction mode based on the SATD, deriving an intra prediction mode of the current block based on the first intra prediction mode, and generating a prediction block of the current block based on the intra prediction mode.
- Derive a most probable mode (MPM) list based on intra prediction modes of neighboring blocks.
- Generate prediction pixels using candidate modes in the MPM list or intra prediction modes of neighboring blocks.
- Calculate the sum of absolute transformed difference (SATD) between prediction pixels and reconstructed pixels.
- Derive a first intra prediction mode based on the SATD.
- Derive an intra prediction mode of the current block based on the first intra prediction mode.
- Generate a prediction block of the current block based on the intra prediction mode.
