Abstract
A method, computer program, and computer system is provided for encoding/decoding video data. Video data including (1) a chroma component having a first nominal angle and a first delta angle and (2) a luma component having a second nominal angle and a second delta angle is received. An index associated with the first delta angle is parsed by an encoder and parsed by a decoder. The video data is encoded and/or decoded using intra prediction based on the parsed index.
Claims20
A method of video decoding, executable by a processor, the method comprising:
- parsing an index associated with a first delta angle associated with a chroma component of video data;
- and
- decoding the video data using intra prediction based on the parsed index.
A computer system for decoding video data, the computer system comprising:
- one or more computer-readable non-transitory storage media configured to store computer program code;
- and
- one or more computer processors configured to access said computer program code and operate as instructed by said computer program code, said computer program code including:
- parsing code configured to cause the one or more computer processors to parse an index associated with a first delta angle associated with a chroma component of video data;
- and
- decoding code configured to cause the one or more computer processors to encode the video data using intra prediction based on the parsed index.
A non-transitory computer readable medium having stored thereon a computer program for encoding video data, the computer program configured to cause one or more computer processors to:
- parse an index associated with a first delta angle associated with a chroma component of video data;
- and
- decode the video data using intra prediction based on the parsed index.
