Early determination of mode decision for HEVC

In this paper, we propose a fast decision method scheme to reduce encoder complexity of high efficiency video coding. It is an early detection of SKIP mode in one CU-level based on the differential motion vector (DMV) and coded block flag (CBF). Experimental results show that the encoding complexity can be reduced by up to 34.55% in random access (RA) configuration and 36.48% in low delay (LD) configuration with only a little bit of rate increment compared to the high efficiency video coding test model (HM) 4.0 reference software.
