Docomo demos HEVC (H.265) new video coding standard

NTT Docomo has demonstrated HEVC, also known as H.265, a new international video compression standard.

HEVC, is the next generation after H.264/MPEG-4 AVC, which is currently in widespread use. Compared with that specification, it can double the data compression ratio.

“The system called HEVC was approved by ITU and ISO on January 25. Here, you can see how good the picture quality is. On the left is the video format called H.264 AVC, which is currently the norm. On the right is the new HEVC. You can see the difference in picture quality achieved with the same data volume. Compared with the previous system, HEVC gives a considerably better picture.”

Docomo has been a big proponent for the standardization of HEVC since it was proposed in 2007. Consequently, Docomo’s own specification, to enable use for mobile applications, has been adopted. Docomo has also suggested ways to improve aspects such as compression performance. From now on, Docomo will consider incorporating HEVC into its video services, such as their video and anime store.

“This is codec software developed by Docomo. It uses a PC to play video four times the size of Full HD at 60 fps in real time. We think 60 fps video with a 4K display size like this is a world first.”

“The data volume is about 10 Mbps, so as long as the environment’s in place, in the future, we think using HEVC will enable video this good to be sent over the mobile network.”

In March, Docomo will start licensing HEVC codec software for Full HD on smartphones. Because this software decodes HEVC video efficiently, it eliminates delays and drop-outs due to lack of processing speed, enabling smooth, real-time video.

“We’d like to distribute this software to service providers so they can move ahead with development. By enabling this system to be used worldwide, we’d like to reduce mobile traffic substantially.”
