Abstract
In a method of encoding a video sequence into a bitstream, an encoder determines, based on a value of a first encoded flag, whether to encode a second flag into the bitstream. The first flag indicates whether sign data hiding is turned off at a slice level for a video frame. The second flag indicates whether transform skip residual coding is turned off at the slice level for the video frame.
Claims23
A method of encoding a video sequence into a bitstream, the method comprising:
- receiving a video frame for residual coding;
- encoding a first flag into a bitstream, the first flag indicating whether sign data hiding is turned off at a slice level for the video frame;
- and
- determining, based on a value of the first flag, whether to skip encoding a second flag indicating whether transform skip residual coding is turned off at the slice level for the video frame.
A method of decoding a bitstream to output one or more pictures for a video stream, the method comprising:
- receiving a bitstream encoded based on residual coding, the bitstream comprising a first flag indicating whether sign data hiding is turned off at a slice level;
- decoding the first flag;
- and
- determining, based on a value of the first flag, whether to decode a second flag indicating whether transform skip residual coding is turned off at the slice level.
A non-transitory computer readable storage medium storing a bitstream of a video, the bitstream comprising:
- a first flag indicating whether sign data hiding is turned off at a slice level,
- wherein when the first flag has a first value, the bitstream further comprises a second flag indicating whether transform skip residual coding is turned off at the slice level, and
- wherein when the first flag has a second value, the bitstream further does not comprise the second flag.
