The New H.265 Video Format Will Help Chew Up Video So Your Network Can Swallow It

Streaming video is the future. Well, it’s the present, but the future too. And as resolutions increase, it’s going to be a tougher and tougher proposition to pipe all that data to your screen of choice in a timely fashion. Fortunately, the new H.265 standard has been approved by the ITU and it’s here to help.

Also known as High Efficiency Video Coding (HEVC), the H.265 standard should make HD video streaming easier and could make even UHD (formerly known as 4K) streaming feasible whenever that becomes a thing that people actually might want to do. Ideally, new compression techniques that come along with the H.265 standard should make 1080p streaming possible while only requiring about half as much of the data that’s required today.
On top of making it easier to stream increasingly high definition content, the new standard should also make it easier to stream stuff on less-than-zippy networks, bringing higher quality video content to mobile devices with less of a wait on buffering.
But of course, the effects won’t be instant. Sure, software encoders are imminent, but we won’t really start reaping the benefits until the standard gets adopted down in the chips. H.265 won’t be able to shoulder the whole burden of increasingly mammoth streaming video loads, but it should be able to lend a hand, and that’s worth something at least. [ITU via Engadget]

I had a look at a HEVC sample (link) which is a 35MB file containing 4 minutes of 1080p video (Avatar trailer). It definitely looks impressive (appears as good as HD satellite broadcasts), but then again this is the only sample so I’m sure they optimised it. At this bitrate, a 2 hour 1080p film would fit in 1GB.

Based on what I’m reading, the current encoder is incredibly slow, with this post mentioning 7 to 9 hours to encode 200 frames of 1080p video, which works out at roughly 1 hour per 1 second of video. :eek:

Looks like it’ll finally put the upcoming flagship Haswell CPUs to good use. :iagree:

I am really looking forward to this new H-265 format. Its just amazing at what is happening in Tech these days. I was reading that the new 4770K is being OCd to 7.0GHZ without LN2.:wink:
