  • Residual transformation and inverse transformation in video coding systems and methods
    Patent number: 10735729
    Abstract: A transform block processing procedure wherein a maximum coding-block size and a maximum transform-block size for an unencoded video frame is determined. The unencoded video frame is divided into a plurality of coding-blocks including a first coding-block and the first coding block is divided into at least one prediction block and a plurality of transform blocks. The size of the transform blocks depend at least in part on the size of the coding block and the corresponding prediction blocks. The transform blocks are then encoded, thereby generating a video data payload of an encoded bit-stream. A frame header of the encoded bit-stream, including a maximum coding-block size flag and a maximum-transform-block-size flag, is generated.
