VIDEO CODING USING MAPPED TRANSFORMS AND SCANNING MODES - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240129531 titled 'VIDEO CODING USING MAPPED TRANSFORMS AND SCANNING MODES
Simplified Explanation
A video encoder may transform residual data using a selected transform from a group of transforms, creating a two-dimensional array of transform coefficients. A scanning mode is then chosen to convert these coefficients into a one-dimensional array. The combination of transform and scanning mode is based on an intra-prediction mode, with the scanning mode potentially influenced by the transform used.
- The video encoder transforms residual data using a selected transform from a group of transforms.
- The transform creates a two-dimensional array of transform coefficients.
- A scanning mode is chosen to convert the coefficients into a one-dimensional array.
- The combination of transform and scanning mode is based on an intra-prediction mode.
- The scanning mode may also be influenced by the transform used.

Original Abstract Submitted
a video encoder may transform residual data by using a transform selected from a group of transforms. the transform is applied to the residual data to create a two-dimensional array of transform coefficients. a scanning mode is selected to scan the transform coefficients in the two-dimensional array into a one-dimensional array of transform coefficients. the combination of transform and scanning mode may be selected from a subset of combinations that is based on an intra-prediction mode. the scanning mode may also be selected based on the transform used to create the two-dimensional array. the transforms and/or scanning modes used may be signaled to a video decoder.
