METHOD AND APPARATUS FOR INTRA SUB-PARTITIONS CODING MODE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18497223 titled 'METHOD AND APPARATUS FOR INTRA SUB-PARTITIONS CODING MODE
Simplified Explanation
The abstract describes apparatuses and methods for Intra Sub-Partitions (ISP), focusing on determining the size of a chroma transform block based on certain conditions related to the chroma format of the picture.
- The method involves obtaining information about ISP and determining the size of a chroma transform block based on SubWidthC and SubHeightC when a specific condition is met.
- The condition includes using ISP to split the luma coding block, with SubWidthC and SubHeightC being variables dependent on the chroma format information.
- The chroma format information indicates the chroma format of the picture the coding unit belongs to, which can be 4:2:0, 4:2:2, or 4:4:4.
- This method is accurate and versatile in determining the size of the chroma transform block for ISP.

Original Abstract Submitted
Apparatuses and methods for Intra Sub-Partitions (ISP) are provided. The method includes: obtaining information of ISP, and determining a size of a chroma transform block (TB) of the coding unit based on SubWidthC and SubHeightC when at least a first condition is fulfilled. The first condition includes the information of ISP indicates that ISP is used for splitting the luma coding block. SubWidthC and SubHeightC are variables depending on chroma format information. The chroma format information indicates a chroma format of a picture the coding unit belongs to. The method can apply to all chroma format. The chroma format includes at least one of: 4:2:0, or 4:2:2, or 4:4:4. An accurate and versatile way to determine the size of the chroma transform block for the ISP is achieved.
