SECONDARY TRANSFORM DESIGNS FOR PARTITIONED TRANSFORM UNITS IN VIDEO CODING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18162962 titled 'SECONDARY TRANSFORM DESIGNS FOR PARTITIONED TRANSFORM UNITS IN VIDEO CODING
Simplified Explanation
The patent application describes a device that applies a primary transform to video data and determines whether intra sub-partitioning is applied to the data. If intra sub-partitioning is applied and the primary transform size is at least a predetermined size, the device applies a secondary transform to the primary transform coefficients and codes the video data based on the secondary transform.
- The device applies a primary transform to video data.
- It determines whether intra sub-partitioning is applied to the video data.
- If intra sub-partitioning is applied and the primary transform size is at least a predetermined size, the device applies a secondary transform to the primary transform coefficients.
- The device codes the video data based on the secondary transform.
Potential Applications
- Video compression and encoding systems
- Video streaming platforms
- Video editing software
Problems Solved
- Efficient video compression and coding
- Improved video quality and resolution
- Reduced bandwidth requirements for video streaming
Benefits
- Higher video compression ratios
- Enhanced video quality and resolution
- Reduced bandwidth usage for video streaming
Original Abstract Submitted
An example device applies a primary transform to a current block of video data to create primary transform coefficients. The device determines whether intra sub-partitioning is applied to the current block of video data. The device applies a primary transform to the current block. The device also determines whether a primary transform size for the current block of video data is at least a predetermined size. Based on intra sub-partitioning being applied and the primary transform size being at least the predetermined size, the device applies a secondary transform to primary transform coefficients and codes the current block of video data based on the secondary transform.
