Document Type and Number:
WIPO Patent Application WO/2019/137008
Kind Code:
A1
Abstract:
Embodiments of the present application provide a method and a device for group identification of uniform transform unit modes, and an electronic device. The method comprises: identifying respective group units according to uniform transform unit modes of code units in the group units, wherein, if the uniform transform unit modes of the code units in a group unit all have the same first value, a first flag is set to a second value and said group unit is identified using the first flag; and identifying the code units in each group unit according to the uniform transform unit modes of the code units in the group unit. According to the present application, if uniform transform unit modes of code units in a group unit are the same, the uniform transform unit modes of the code units in the group unit are not identified, thereby reducing required storage capacity, transmission capacity, and processing capacity.
