Title:
A method and a device of coding block flag coding in efficient video coding
Document Type and Number:
Japanese Patent JP6223998
Kind Code:
B2
Abstract:
A method includes receiving the video bitstream from a media or a processor, recovering a first coded block flag (cbf) from the video bitstream based on a context-based adaptive binary arithmetic coding (CABAC) decoding process according to a first context formation, wherein the first cbf is associated with a first transform unit (TU) of a first color component, and the first cbf indicates whether the first TU of the first color component has at least one non-zero transform coefficient, and recovering a second cbf from the video bitstream based on the CABAC decoding process according to a second context formation, wherein the second cbf is associated with a second TU of a second color component, and the second cbf indicates whether the second TU of the second color component has at least one non-zero transform coefficient.
