Intra Block Copy Vector Difference Wrap Around - A simplified explanation of the abstract
This abstract first appeared for US patent application 18399369 titled 'Intra Block Copy Vector Difference Wrap Around
The abstract of the patent application describes a decoder that processes a bitstream to reconstruct a current block based on a block vector predictor and block vector differences.
- The decoder determines a second block vector difference based on the first difference and the displacement of a location from the current block.
- It calculates a block vector using the second difference and the predictor.
- The current block is reconstructed using a reference block indicated by the block vector.

Original Abstract Submitted
A decoder receives, from a bitstream, an indication of a block vector predictor (BVP) and a first block vector difference (BVD) for a current block. The decoder determines a second BVD based on: the first BVD and whether a location displaced from the current block by a sum of the BVP and the first BVD is outside a reference region. The decoder calculates a block vector (BV) based on a sum of the second BVD and the BVP. The decoder reconstructs the current block based on a reference block indicated by the BV.
