Application: Systems and methods for coding transform data (Patent ID: US20240114139A1)

The patent filed by Sharp Corp. pertains to a video coding device that performs transform data coding using specific techniques. The method involves encoding and decoding transform data for video coding based on intra prediction techniques. The process includes determining conditions associated with a coding unit, signaling a coding unit level index syntax element to indicate the application of a secondary transform and the matrix used, and inferring the element to be 0 when the secondary transform is not applied. The conditions for this determination include the size of the coding unit being greater than or equal to 16x16 and the absence of an intra prediction technique generating a predictive video block using a weighted combination of reference samples.

The device described in the patent comprises processors configured to determine conditions associated with a coding unit, parse a coding unit level index syntax element to indicate the application of a secondary transform and the matrix used, and infer the element to be 0 when the secondary transform is not applied. The conditions for this determination align with those mentioned in the method claims, including the size of the coding unit and the absence of a specific intra prediction technique. Additionally, the device is specified to include a video decoder, emphasizing its application in video processing and coding technologies.
