ITU approves the H.265 video format, takes us closer to high-quality mobile video
Any smartphone owner who's ever watched a streaming HD video buffer... and buffer... and buffer on even LTE connections will appreciate the ITU's speediness today. Just months after MPEG proposed the extra-miserly H.265 video codec, the ITU has approved it as an official standard. As it's greenlit so far, the format (also known as High Efficiency Video Coding) includes 8-bit, 10-bit and photo-oriented profiles that should cover most 2D capture and playback. Pros are promised 12-bit and chroma profiles in the future, while there's work on 3D for all of us. We'll have to wait for both software support and hardware acceleration to reap the rewards, but there should be many: the halved bandwidth requirements have obvious benefits for cellular devices as well as 4K media delivery for that rash of giant TVs about to hit the market. Let's hope that camera and mobile device makers are just as impatient as we are.
MPEG drafts twice-as-efficient H.265 video standard, sees use in phones as soon as 2013
All of that squabbling over H.264 may be rendered moot in the near future. The Motion Picture Experts Group (better known as MPEG) has just let us know that it was quietly drafting a new video standard while everyone was on summer vacation last month: H.265, also called High Efficiency Video Coding, promises to squeeze video sizes with double the efficiency of H.264. As you might imagine, this could lead either to a much smaller video footprint for bandwidth-starved mobile users or a hike to image quality with the same size as before. Imagine fast-loading HD streaming on 4G, or cable TV without all the excess compression, and you've got the idea. Ericsson Research visual technology lead Per Fröjdh anticipates H.265 coming as soon as 2013, when our smartphones and tablets are most likely to play it first. TV and other areas might have to wait, although Fröjdh is offering a consolation prize -- he's teasing a separate MPEG project that could give us glasses-free, compressed 3D video as a standard by 2014.
