Title:
MODE INFORMATION ENCODING AND DECODING METHOD, DEVICE, AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/109264
Kind Code:
A1
Abstract:
A mode information encoding and decoding method, a device, and an electronic apparatus. The encoding method comprises: determining a uniform transform unit mode adopted for coding units of an image; determining a binary digit corresponding to the uniform transform unit mode according to the size of the coding units and/or a pre-determined number of uniform transform unit modes; and encoding the binary digit corresponding to the uniform transform unit mode into a bit stream of the image. The invention achieves encoding and decoding of uniform transform unit mode information, and reduces the bit cost of encoding.
