In the method, the device determines, for a current luma transform block in a coding unit, whether an intra subpartition (ISP) split type is an ISP mode. In response to determining that the intra subpartition split type is not the ISP mode, the device determines a first context index for a Coded Block Flag (CBF) flag of the current luma transform block as being equal to zero or one, where the CBF flag specifies whether the current luma transform block comprises one or more transform coefficient levels not equal to zero. In response to determining that the intra subpartition split type is the ISP mode, the device determines the first context index based on a CBF variable of a previous luma transform unit in the coding unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Coding of transform coefficients in video coding","description":"Methods and devices for video coding are provided.
