Cross-component prediction for bandwidth compression

A method of graphics processing, comprising:

• obtaining an indication of source data associated with a plurality of source components, wherein the plurality of source components includes a first source component and a second source component;
• coding the first source component based on a first prediction algorithm and the second source component based on the first prediction algorithm and a second prediction algorithm;
• determining a first rate of the first prediction algorithm and a second rate of the second prediction algorithm based on the coding of the first source component and the second source component;
• and
• selecting the first prediction algorithm or the second prediction algorithm for a portion of a coding unit based on the first rate of the first prediction algorithm and the second rate of the second prediction algorithm.

A computer-readable medium storing computer executable code for graphics processing, the code when executed by a processor causes the processor to:

• obtain an indication of source data associated with a plurality of source components, wherein the plurality of source components includes a first source component and a second source component;
• code the first source component based on a first prediction algorithm and the second source component based on the first prediction algorithm and a second prediction algorithm;
• determine a first rate of the first prediction algorithm and a second rate of the second prediction algorithm based on the coding of the first source component and the second source component;
• and
• select the first prediction algorithm or the second prediction algorithm for a portion of a coding unit based on the first rate of the first prediction algorithm and the second rate of the second prediction algorithm.
