The memory unit is configured to store a hash table that includes at least one hash index corresponding to reference blocks in the picture, the reference blocks being a subset of available blocks in the picture. The processor is configured to map a current block to a hash index in the hash table based on the application of a hash function to the current block, identify, from the hash table, reference blocks that correspond to the hash index, select a prediction block from among the reference blocks based on a comparison of the current block to the reference blocks, and encode the video information using the selected prediction block."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hash-based encoder search for intra block copy","description":"An apparatus configured to encode video information of a picture includes a memory unit and a processor in communication with the memory unit.
