FLEXIBLE ACTIVATION OF MULTIPLE TRANSFORM SELECTION FOR INTER-CODING IN VIDEO CODING - A simplified explanation of the abstract

• This abstract for appeared for patent application number 18297463 Titled 'FLEXIBLE ACTIVATION OF MULTIPLE TRANSFORM SELECTION FOR INTER-CODING IN VIDEO CODING'

Simplified Explanation

The abstract describes a method used by a video coder to determine whether to apply an inter-MTS mode to video data. The video coder can adjust the block size for applying the inter-MTS mode based on certain criteria. The video decoder then determines whether the inter-MTS mode is enabled for a block of video data by comparing the block size to the specified criteria. If the inter-MTS mode is enabled, the block is coded using this mode by applying various transforms to the video data.

Original Abstract Submitted

A video coder may adaptively determine whether to apply an inter-MTS (multiple transform set) mode to video data. The video coder may adaptively determine one or more of a maximum block size or a minimum block size for applying an inter-MTS mode. The video decoder may determine whether the inter-MTS mode is enabled for a block of video data based on a size of the block compared to one or more of the minimum block size or the maximum block size. and code the block using the inter-MTS mode based on the inter-MTS mode being enabled. Coding the block using the inter-MTS mode includes applying one or more transforms of a plurality of transforms to transform coefficients associated with the block of video data.
