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.
