In the method, reconstructed samples of a reconstructed block of a picture are stored in a first reference sample memory. The first reference sample memory is configured to store at least one set of a number of luma samples and corresponding chroma samples of the reconstructed block. Further, reconstructed samples of a current block of the picture are stored in a second reference sample memory. The second reference sample memory is configured to store only one set of the number of luma samples and corresponding chroma samples of the current block. A current sub-block in the current block is reconstructed using an intra block copy (IBC) mode based on the stored reconstructed samples of a reference sub-block of the reconstructed block or the stored reconstructed samples of a reference sub-block of the current block."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reference sample memory size restrictions for intra block copy","description":"A method for video decoding at a decoder is provided.
