In a first embodiment, if a collocated luminance block is not coded in current picture reference mode, a luma vector from a left chroma subblock is used. When the left chroma subblock is not coded in current picture reference mode, a luma vector from the above chroma subblock is used, and if that is not available, a default vector is used. In a second embodiment, a collocated luma block partition is used to derive a chroma block vector."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Current picture referencing block vector initialization with dual tree","description":"A chroma component block vector is initialized using one of a neighboring or collocated luma block vector when current picture referencing mode is used and when dual tree is enabled.
