AFFINE PREDICTION IN VIDEO CODING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240137556 titled 'AFFINE PREDICTION IN VIDEO CODING
Simplified Explanation
The patent application describes a device for video decoding that utilizes 6-parameter affine prediction to generate predictive blocks for video data reconstruction.
- The device obtains a syntax element from a bitstream indicating whether 6-parameter affine prediction is enabled for certain blocks.
- If the prediction is enabled, the device uses the 6-parameter affine prediction to generate a predictive block for the corresponding block.
- The device then reconstructs the block using the predictive block and residual data.

Original Abstract Submitted
a device for video decoding can be configured to obtain, from a syntax structure in a bitstream comprising an encoded representation of the video data, a syntax element indicating whether 6-parameter affine prediction is enabled for blocks corresponding to the syntax structure, wherein the blocks corresponding to the syntax structure comprise a first block; based on the syntax element indicating that the 6-parameter affine prediction is enabled for the blocks corresponding to the syntax structure, use the 6-parameter affine prediction to generate a predictive block for the first block; and use the predictive block and residual data to reconstruct the first block.
