Abstract:

The Intra Block Copy (IntraBC) is a newly adopted tool in the HEVC extension for the screen content video coding. The IntraBC tool efficiently encodes repeating patterns in a picture. The current IntraBC scheme achieves about 1.0% bit-rate reduction on average and up to 4.3% bitrate reduction on natural content video for a database consisting of 2K, 4K, and 8K sequences. In this paper, we propose to improve the IntraBC with a template matching block vector and a fractional search IntraBC. With these two tools, the gain on natural content video coding can be further improved by 0.5% on average and up to 2.0%.
