UltraViolet movie format to use Dolby Digital Plus encoding, keep sound thumping across platforms
Movies 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.
Microsoft reportedly preparing Silverlight-like app framework ahead of Xbox Live update
Earlier this month, Microsoft announced a new slate of Xbox Live partnerships with Verizon, Comcast, and a host of other content providers. Now, the company has unveiled new details about the code upon which these new apps will run. Sources close to the situation tell GigaOM that the new framework, code-named "Lakeview," will be based on Silverlight, but will also bring a few new features from Xbox Kinect, including voice recognition and gesture-based controls. More intriguing, perhaps, are insider claims that Microsoft's new content partners stream video using Apple's HTTP Live Streaming, rather than Redmond's Smooth Streaming. GigaOM's sources went on to say that Microsoft has been introducing major changes to the platform over the past few weeks, in the hopes of having it ready for third-party developers once the Xbox Live update rolls out. Spokespersons for Xbox and Silverlight said they have "nothing to announce" about the new framework, though GigaOM reports that Redmond is aiming to release the update on Black Friday.
Zune HD specs fill in the blanks on video format support, battery life and more
Now that everything Zune HD is official and available for pre-order, Microsoft has seen fit to loose official specs, putting to rest -- at least until we can do a full hands on -- questions about what to expect from the OLED touchscreen packing device. From dimensions (52.7 mm x 102.1 mm x 8.9 mm, 2.6 oz) to battery life (24 hours for music with wireless off, up to 4 hours of video) and charge time (3 hours, 2 hours to 90%.) While the official site (incorrectly) currently lists max video res at barely-better-than-DVD 720 x 480, we contacted Microsoft and received the official specs on video support, and if for some reason you needed to hear it again: the Tegra chip is a beast. Ready for HDTV playback when it's plugged into the AV dock, the Zune software supports up to 1280 x 720, 30 frames per second at a max 14 Mbps bitrate for WMV HD and h.264 sources. Confirmed still a bummer? No wireless video streaming from the Zune Video Marketplace, though the specs do indicate that purchases and rentals will work across all three screens, PC, Zune and Xbox 360. Check the corrected specs after the break, now all that's left is getting some alone time with one.Update: Microsoft has hit us with the corrected & updated spec list with a slight change to battery and charge specs: 33 hours of life playing music with no wireless, up to 8.5 hours of video. 3 hours to charge from PC, 2 hours via AC adapter. Hopefully that's long enough to cover your one man rave in the woods far away from A/C outlets. Check the PDF for yourself, but beware, as Microsoft has informed us one typo remains, as the Zune HD can hold up to 22 / 48 hours (16GB / 32GB) of video optimized for the device, no matter what the official sheet says.
Zune HD specs fill in the blanks on video format support, battery life and more - Update: now with more, better!

Akamai sees more publishers switching to HD video online
Sure Akamai sponsored a new IDC whitepaper finding smooth video and high resolution is important to most online audiences -- services it is conveniently positioned to help provide -- but that doesn't mean the results are wrong. Last year a similarly self promotional survey found 75% or broadcasters planning HD online and in the last twelve months we've had an explosion of HD on the net, from the Olympics and NCAA Championships to Netflix, Amazon, MLB and YouTube to 1080p from DirecTV, DISH and VUDU. Key results of the 2009 analysis? Publishers need HD streaming to keep up with the competition, video quality is important, and high definition means users will stick around longer. Notable in its absence is the complaint many have about downloads and streams, no high quality / surround audio. Just an idea for the 2010 survey guys.
NBCOlympics.com using Silverlight 3, Smooth Streaming for Winter Olympics video
The Beijing Olympics broadcast benefited greatly from high quality streams available on the NBCOlympics.com website, and it looks like the 2010 Games in Vancouver will be no different. To that end, Microsoft's released server side enhancements like Smooth Streaming technology for adaptive streaming with Silverlight to keep the video streams moving smoothly, and even enable DVR-like features in a live stream without requiring dedicated video servers, all so viewers can get smooth 720p throughout the event. By then Silverlight 3 should be out of beta, which promises support for up to 1080p resolution, native playback of MP4 formats like h.264 and hardware graphics acceleration. Honestly we'd expect nothing less, and while word is CTV, HSN and others will be among the first to take advantage, we're waiting for Netflix to pick up the baton and deliver browser based PQ that rises to the level of Xbox 360 and other players, plus more HD.
