N2 - In this paper, we propose a novel quantization parameter offset optimization scheme for screen content videos based on the high correlation among adjacent frames. Firstly, we define a measurement of inter-frame correlation for successive frames. Then, according to the defined correlation measurement, quantization parameter offset for different frames is appropriately adjusted. Experimental results demonstrate that the proposed optimization scheme brings coding performance improvement. The maximum BD-rate gain can be over 3.8% and the average performance gain is over 2% compared with the reference software.
