Chroma Transform Type Determination - A simplified explanation of the abstract
This abstract first appeared for US patent application 18273666 titled 'Chroma Transform Type Determination
Simplified Explanation
The patent application describes a method for encoding image blocks by generating luma and chroma prediction blocks, generating luma and chroma residual blocks, transforming the residual blocks, quantizing the transformed blocks, and entropy encoding the quantized blocks.
- Luma prediction block is generated.
- Luma residual block is generated.
- Luma residual block is transformed using a luma transform type.
- Quantized luma block is generated.
- Chroma prediction block is generated.
- Chroma residual block is generated.
- Initial chroma transform type is determined as the luma transform type.
- Quantized chroma block is generated using the chroma residual block transformed by a final chroma transform type.
- Quantized chroma block is entropy encoded.
- Final chroma transform type is determined based on the initial chroma transform type or the default transform type.
- Quantized coefficients of the quantized chroma block depend on quantized coefficients of the quantized luma block.

Original Abstract Submitted
For a coding block of an image, a luma prediction block is generated, a luma residual block is generated, a quantized luma block is generated after transforming the luma residual block using a luma transform type, and the quantized luma block is entropy encoded. A chroma prediction block is generated, a chroma residual block is generated, an initial chroma transform type for the chroma residual block is determined as the luma transform type, a quantized chroma block is generated using the chroma residual block transformed by a final chroma transform type, and the quantized chroma block is entropy encoded. When the initial chroma transform type is other than a default transform type, the final chroma transform type is the initial chroma transform type or the default transform type, and quantized coefficients of the quantized chroma block depend upon quantized coefficients of the quantized luma block.
