Abstract
A method performed by at least one processor of a video decoder including receiving a video bitstream comprising an encoded video sequence and quality enhancement signaling information; decoding the encoded video sequence to generate a decoded video sequence; and performing a quality enhancement process in accordance with the quality enhancement signaling information and a bit-depth condition.
Claims20
A method performed by at least one processor of a video decoder, the method comprising:
- receiving a video bitstream comprising an encoded video sequence and quality enhancement signaling information;
- decoding the encoded video sequence to generate a decoded video sequence;
- and
- performing a quality enhancement process in accordance with the quality enhancement signaling information and a bit-depth condition.
A method performed by at least one processor in an encoder, the method comprising:
- receiving a video sequence;
- performing, based on a bit-depth condition, a quality enhancement process on the video sequence to generate a transformed video sequence;
- encoding the transformed video sequence to generate an encoded video sequence;
- and
- generating a video bitstream comprising the encoded video sequence and quality enhancement signaling information corresponding to the quality enhancement process.
A non-transitory computer readable medium storing a video bitstream that is decoded by a method comprising:
- receiving a video bitstream comprising an encoded video sequence and quality enhancement signaling information;
- decoding the encoded video sequence to generate a decoded video sequence;
- and
- performing a quality enhancement process in accordance with the quality enhancement signaling information and a bit-depth condition.
