ITU agrees on HEVC h.265 codec

h-265-logo,Q-D-349573-3The ITU announced today that it’s members have agreed upon a new high efficiency video codec. Dubbed HEVC H.265, the new format is designed to improve on and ultimately replace the current king of all codecs, H.264/MPEG-4 AVC which covers 80% of internet video today.

So far, a lot of attention has been given to the codec’s ability to deliver the same quality video as 264 with only half the bandwidth. That kind of efficiency improvement is a big deal– it could reduce strain on networks and bring high-resolution 4K content delivery over the internet closer to reality.

This paves the way for fantastic looking color as wide gamut-capable hardware starts to become more widely available.
