To reduce the computational complexity,a fast inter mode selection algorithm for screen conte nt coding (SCC) is proposed in this paper.First,the change of luminance values between current pi xel and its co-located pixel is utilized to detect static regions and Skip mode is applied. Next,given that a large number of horizontal and vertical edges occur in screen content,corresp onding prediction unit (PU) partition modes are selected according to coding unit (CU) activity,an d the number of PU modes for inter prediction can be reduced.Finally,depth range of current CU is predicted by utilizing the CU depths of adjacent CUs in both temporal and spatial domains, and unnecessary depths are skipped.Experimental results show that compared with SCM-8.0ancho r,the proposed algorithm can save 43.6% and 49.09% encoding time on average with 3.06% and 3.43% BD-rate loss for random access and low delay configurations,respectively,while the loss of v ideo quality can be negligible.Therefore,this study shows a certain reference value for the real-ti me application of SCC.
