UltraViolet movie format to use Dolby Digital Plus encoding, keep sound thumping across platforms

UltraViolet movie format to use Dolby Digital Plus encoding, keep sound thumping across platformsMovies encoded in UltraViolet's Common File Format represent just one of multiple takes on paid internet video -- what's to make them stand out? The answer might just be Dolby Digital Plus audio encoding, which should be a staple feature of CFF from now on. A newly ready development kit lets producers feed the multichannel sound to hardware and apps that can recognize it, including web-based avenues like Apple's HTTP Live Streaming, Microsoft's Smooth Streaming and MPEG's DASH. Just in case a few devices fall through the cracks, Dolby is talking directly with digital production firms like castLabs, Digital Rapids and Elemental Technologies to make sure the audio codec's implementation truly spans platforms. We don't know how soon movies will take advantage of the upgrade, but the Dolby addition lends weight to a fledgling format that might have as fierce a battle in home theaters as it does on PCs and tablets.

MPEG drafts twice-as-efficient H.265 video standard, sees use in phones as soon as 2013

MPEG drafts twiceasefficient H265 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.
