HEVC is video compression method has been standardized by ISO / IEC and ITU-T. The new standard will need only half the bit rate of its predecessor, ITU-T H.264 / MPEG-4 Part 10 - Advanced Video Coding - (AVC). For instance, a 800 x 480, 30 fps HEVC video can be delivered with about 800kbps, while the same video requires 1.6Mbps in the MPEG-4 AVC format.
DoCoMo's new decoder will support playback of 1,920 x 1,080 / 30fps video on smartphones, and up to 4K (3,840 x 2,160 / 60fps) video on PCs.
The company will showcase the new decoder later this month at its booth at the "Mobile World Congress 2013" in Barcelona.
