Telecom group approves bandwidth-saving H.265 standard

Stephen Lawson, InfoWorld:

An ITU group has approved a successor to the H.264 video encoding standard, opening the door to future video transmission using only half the bandwidth that’s now required.

H.265 is also known as High Efficiency Video Coding (HEVC). It improves video quality and doubles the data compression ratio compared to H.264 (the standard heavily leveraged in Apple’s QuickTime video technology). It scales up to 8192 x 4320 resolution, making it suitable for use with Ultra High Definition (UHD) signals.

  • Since we’re a ways away from any serious 4K impact in the market, the question is how is Apple going to play the h.265 advantage with delivery of video content?

    Reduce the size of downloads by keeping a relative quality to existing h.264 files OR…

    Keep file sizes the same as now, and basically double the picture quality… and narrowing the advantage of BluRay.

    I know a little about this business….the problem with h.265 is that while it dramatically reduces the transmitted bitrate (or file size) for a given resolution and QP , it ramps up the demands on encode. So you are very likely to see just h.265 decode in mobile devices and roku/apple tv boxes soon.

  • This is good news. It’ll be interesting to see how big the benefit of the new standard is in everyday media consumption. As @tylernol:disqus alluded to, this new standard will probably need a lot more processing power to be encoded and decoded. It’s up to hardware producers to add dedicated routines to their devices as fast as possible.
