Title:
ENCODING METHOD FOR VIDEO DATA, DECODING METHOD FOR VIDEO DATA, COMPUTING DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/274044
Kind Code:
A1
Abstract:
The present disclosure provides an encoding method for video data, a decoding method for video data, a computing device, and a medium. The encoding method comprises: performing bit-depth transformation on an image to generate a transformed image and generate bit-depth transformation information, wherein the bit-depth transformation information indicates information associated with the bit-depth transformation performed on the image, and the image is one image frame of video data; and encoding the transformed image to generate encoding information corresponding to the transformed image, wherein the bit-depth transformation information and the encoding information are used for forming a bit stream. The decoding method comprises: parsing, from a received bit stream, bit-depth transformation information and encoding information that correspond to an image, wherein the bit-depth transformation information indicates information associated with bit-depth transformation performed in the process of encoding the image; and performing decoding and transformation according to the bit-depth transformation information and the encoding information to generate a display image.
