EMOS-based spatio-temporal rate control technique for 4K60P videos

The authors have proposed a spatio-temporal rate control technique based on a maximization of the estimated Mean Opnion Score(EMOS), and applied it to video coding. This paper extends the technique to 4k60P videos. To evaluate the effectiveness of the apporach, the technique is applied to a 4K60P sequence comprising four scenes with different spatio-temporal activity. The results suggest that the maximum frame rate 60fps is insufficient for some videos, and that 120 fps or higher is desireble in order to make the best of the 4K resolution.
