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.

Microsoft clarifies codec position for Windows 7

Graphedit graph
Last week it was uncovered that the way 3rd party codecs will work in Windows 7 is going to be different. Microsoft wasn't exactly happy with our interpretation of the events and so we received a nice email today clarifying a few points; like the fact that Windows will "continue to use codecs and other format technologies from third-party companies." This is great and all, but doesn't exactly jive with what the developers of some third party companies are saying. The real point of contention seems to be that in Windows 7, if the video you want to watch is naively supported by Windows, there's no easy way choose a different codec, like the popular ffdshow. Now obviously you'll be able to add support for a codec not already supported by Windows, but that isn't going to be enough for some. That's not to say there isn't a way to override this out of the box behavior, but it isn't like it used to be. But honestly, a part of us understands what Microsoft is trying to do here. Anyone who has ever messed up their direct show filter priority with some hack codec pack knows the pain of re-installing Windows just to get a video to play again. So in a strange way this might actually be a decent compromise. Now if it was down right impossible to override the default codecs, it'd be a different story. But based on the current beta builds floating around the net, that doesn't seem to be the case. The full official response from Microsoft is after the break.

IDT brings 6-, 8-, and 10-channel HD audio codecs to the PC

While home theater enthusiasts don't typically have a hard time finding equipment to support nearly any multichannel audio arrangement they can envision, IDT is hoping to assist those PC users out there experience the same bliss with new multichannel HD audio codecs. The IDT92HD73C, IDT92HD73D and IDT92HD73E feature 6-, 8- and 10-channel stereo channels respectively "enabling simultaneous audio and VoIP capability," and while the 6-channel version should be found on high-end laptops, the 8-channel iteration was designed for use in "ultra-high-end" lappies while the 10-channel codec will likely be used in desktop applications. All three offer up stereo 24-bit resolution with sample rates of up to 192kHz and dual S/PDIF outputs for easy integration with multichannel equipment.

Xbox 360: now with H.264, MPEG-4, PlaysForSure

Color us tickled, but we totally missed some of the finest points of all in Microsoft's Xbox 360 spring Dashboard update: they're totally tricking out the video (finally!). No longer will we be confined to our very least favorite video codec, WMV -- the new update will enable Windows Media Connect or Media Center streaming MPEG-4 up to 8Mbps, H.264 up to 15Mbps, and PlaysForSure WMV videos (and, as we understand it, PlaysForSure audio as well). Wow, finally we can actually use the 360 to play video that wasn't recorded off our Media Center or converted by our Zune software (cough, hack). See, was that so hard, Microsoft? Now just hold on to your asses until the week of May 7th, Xbox fans, that's all you've gotta do.
