Outline of Final Research Achievements |
4K60P video transmission requires an efficient video encoder as well as a spatio-temporal rate control technique that maximizes resulting video qualities. This research has aimed at an extention of such a rate control technique, previously proposed by the author, into 4K60P videos, i.e., the rate control tecnique based on a maxmization of an estimated subjective video quality (EMOS). A spatio-temporal EMOS estimation technique for 4K60P videos was first established, and then it was applied to H.265/HEVC encoder to realize an EMOS-maximization-based video encoder. It was also applied to a constant-EMOS coding and a video quality equalization technique to verify the validity of our approach. These experiments have suggeested that a frame rate of 60Hz is often insufficient to make the best of the 4K video resolution.
