Abstract

In this paper, an multi-mini-partition intra block copying (MMPIBC) coding technique for screen contents is presented. In MMPIBC coder, a Coding Unit(CU) with size 8x8 is firstly broken into multiple mini-partitions. Each mini-partition of CU separately select the displacement vector(DV) with the same search range. To further decrease the RD-cost of MMPIBC mode, DV predictor and pseudo three planar search techniques are applied to get more coding gain. Experiments show that for some types of screen contents, the average Bit-rate saving of MMPIBC achieves up to 14.9%.
