Intra Block Copy for Next Generation Video Coding

Intra block copy, or IBC for short, has shown its effectiveness in coding computer-generated contents such as texts and graphics. Therefore, it has been adopted into the HEVC standard version 4, extensions for screen content coding. It is also desirable that intra block copy is considered as a part of the next generation video coding standard, as screen contents have become one of the mainstream video applications. In this paper, an IBC implementation is incorporated into the video coding research software platform hosted by JVET for developing the next generation video coding standard. Simulation results show that with all the advanced coding tools enabled beyond the HEVC in the most-up-to-date JVET, the IBC mode can still achieve a significant coding efficiency improvement on screen content test materials.
