Method for creating an adaptive block vector of the current block in internal block copy (IBC) mode and a computer-readable method storing the bit stream created by this method

Abstract

This proposal suggests a method for creating an adaptive block vector of the current block in Intra Block Copy (IBC) mode, and a readable and writeable computer-stored bit stream created by this method for video encoding using adaptive spatial resolution block vectors. The method of using the spatial resolution of a block vector (BV) indicates the position of the reference block or the sign of the block vector difference to improve encoding efficiency when an intra-block copy (IBC) is applied to the current block.
