VIDEO CODING USING MAPPED TRANSFORMS AND SCANNING MODES - A simplified explanation of the abstract

This abstract first appeared for US patent application 18496152 titled 'VIDEO CODING USING MAPPED TRANSFORMS AND SCANNING MODES

Simplified Explanation

The abstract of the patent application describes a method for transforming residual data using a selected transform and scanning mode, based on an intra-prediction mode. The transformed data is then scanned into a one-dimensional array for encoding.

  • Transform selected from a group of transforms
  • Transform applied to residual data to create a two-dimensional array of coefficients
  • Scanning mode selected to scan coefficients into a one-dimensional array
  • Combinations of transform and scanning mode based on intra-prediction mode
  • Scanning mode may also be selected based on the transform used
  • Transforms and scanning modes signaled to video decoder

Potential Applications

This technology can be applied in video encoding and compression systems to improve the efficiency and quality of video transmission.

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.
