Paper Abstract

In high efficiency video coding (HEVC) scheme, the split structure of the largest coding-unit (LCU) is highly variable and laborious due to its recursive quad-tree representation. Thus, the computational complexity of the HEVC encoder increases dramatically. A fast HEVC encoding method is proposed to predict the split structure of the current LCU by using the same structure of the co-located LCU in the reference or temporally-previous frame, in order to reduce the encoding computational complexity. Simulation results show that the proposed method can achieve a reduction in encoding time of 21.3% on average, with a negligible average PSNR loss and a negligible bit rate increase compared with the original HEVC encoding scheme.
