Coding efficiency of HEVC/H.265 and VP9 compression standards for high resolutions

Abstract

In the last years the interest of multimedia services has markedly increased. This leads to requirements of quality assessment, especially in video domain. Compression together with transmission link imperfection can be considered as two main factors that influence the quality. This paper deals with assessment of impact of HEVC/H.265 and VP9 compression standards on the video quality for high resolutions using objective metrics and defining theirs efficiency. The evaluation is done for four types of sequences with Full HD and Ultra HD resolutions depending on content. The results showed that there is no big difference between the tested codecs - both reach similar efficiency. The average BD-rate saving of VP9 codec relative to H.265 is only 2,24%.
