Abstract:
A method, computer program, and computer system is provided for video coding. Video data having one or more coding coefficients is received. A flipping or rotation operation is performed on the received video data based on selecting a scan region based coefficient coding definition to concentrate the coding coefficients in a scan region. The video data is decoded based on the selected scan region based coefficient coding definition.
