CODING VIDEO DATA USING ADAPTIVE AFFINE BLOCK PREDICTION - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240129525 titled 'CODING VIDEO DATA USING ADAPTIVE AFFINE BLOCK PREDICTION

Simplified Explanation

The example device described in the abstract is a video decoding device that can determine whether motion information of a block of video data is for sub-blocks of the block larger than individual pixels or for the individual pixels themselves. Depending on this determination, the device will perform either sub-block-based affine motion compensation or pixel-based affine motion compensation to form a prediction block for the block, and then decode the block using this prediction block.

• Memory to store video data
• Processing system with one or more processors to determine motion information and perform motion compensation
• Ability to differentiate between motion information for sub-blocks or individual pixels
• Perform sub-block-based or pixel-based affine motion compensation accordingly
• Decode the block using the prediction block

Potential Applications

This technology can be applied in various video decoding systems, such as streaming services, video conferencing platforms, and digital television.

Problems Solved

This technology helps improve the quality of decoded video by accurately predicting motion information for blocks of video data, leading to smoother playback and reduced artifacts.

Benefits

The benefits of this technology include enhanced video quality, improved compression efficiency, and better overall viewing experience for users.

Potential Commercial Applications

Original Abstract Submitted

an example device for decoding video data includes: a memory configured to store video data; and a processing system comprising one or more processors implemented in circuitry, the processing system being configured to: determine whether motion information of a block of video data is for sub-blocks of the block larger than individual pixels of the block or for the individual pixels, the block being associated with data indicating that the block is to be predicted using affine motion compensation; in response to determining that the motion information of the block is for the sub-blocks, perform sub-block-based affine motion compensation to form a prediction block for the block; in response to determining that the motion information is for the individual pixels, perform pixel-based affine motion compensation to form the prediction block for the block; and decode the block using the prediction block.
