The video compression improvements could help with everything from network-constrained mobile video to ordinary broadband streaming video. That's a potential boon for the industry, which is struggling to improve image quality and meet video-streaming demand without taxing bandwidth too much. The High Efficiency Video Coding technology, now in the final stages of standardization, is expected to be twice as good as H.264, meaning that it can match its image quality using only half as many bits per second. The test subjects compared videos compressed with each codec to high-quality 3840x2160 video - quad full HD, or QFHD, one of a few resolutions generally given the 4K label. HEVC has been tested with mathematical measurements, but this study tested 30 actual people, an important factor since technical measurements such as signal-to-noise ratio don't necessarily match up perfectly with actual human perception of quality. 'As ultra-high definition television has recently been demonstrated to be the future of television, the upcoming HEVC video compression standard seems to be one of the key elements towards a wide deployment of 4K and 8K resolutions.' 'The test results clearly exhibited a substantial improvement in compression performance, as compared to AVC,' the researchers said. The new compression technology, called HEVC or H.265, is significantly better than today's prevailing standard video codec, called AVC or H.264, researchers from the Ecole Polytechnique Federale de Lausanne in Lausanne, Switzerland, concluded.

The result could help pave the way for video with at least four times the pixels of today's 1080p standard. MOS represents the average quality rating of 30 testers a higher score is better.įrancesca De Simone,Philippe Hanhart, Martin Rerabek, and Touradj Ebrahimi/EPFLĪ new compression technology represents a significant improvement over today's standard, a new study found.

With one challenging video, HEVC outdid H.264 at four out of five bitrates.
