Abstract
A method, computer program, and computer system is provided for coding video data. Video data is received and entropy-parsed into one or more components. The one or more entropy-parsed components are de-quantized. A joint component secondary transformation (JCST) is performed on the one or more components. The video data is decoded based on one or more residual components corresponding to the joint component secondary transformed components.
Claims20
A method for coding video data, executable by a processor, comprising:
- receiving video data;
- entropy-parsing the received video data into one or more components;
- de-quantizing the one or more entropy-parsed components;
- performing a joint component secondary transformation (JCST) on the one or more components;
- and
- decoding the video data based on one or more residual components corresponding to the joint component secondary transformed components.
A computer system for coding 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:
- receiving code configured to cause the one or more computer processors to receive video data;
- entropy-parsing code configured to cause the one or more computer processors to entropy-parse the received video data into one or more components;
- de-quantizing code configured to cause the one or more computer processors to de-quantize the one or more entropy-parsed components;
- performing code configured to cause the one or more computer processors to perform a joint component secondary transformation (JCST) on the one or more components;
- and
- decoding code configured to cause the one or more computer processors to decode the video data based on one or more residual components corresponding to the joint component secondary transformed components.
A non-transitory computer readable medium having stored thereon a computer program for coding video data, the computer program configured to cause one or more computer processors to:
- receive video data;
- entropy-parse the received video data into one or more components;
- de-quantize the one or more entropy-parsed components;
- perform a joint component secondary transformation (JCST) on the one or more components;
- and
- decode the video data based on one or more residual components corresponding to the joint component secondary transformed components.
