WHDI specification hits 1.0 -- is this what wireless HD has been waiting for?
We've been waiting for what feels like an eternity for wireless HD to really have a place in the world (outside of the elite home cinema world, that is), and while the dream definitely took a hit with the FlyWire's death, it sounds as if things may be rounding the ever-present corner. Amimon, a company responsible for bringing wireless high-def capabilities to all manners of pricey wares through WHDI, has just announced the 1.0 specification of its protocol. Mind you, there are already quite a few big players onboard with the outfit, so hitting the one dot oh could very well kick start a new round of devices (set-top boxes, HDTVs, media streamers, etc.) designed to handle wireless transfers of 1080p material. You can catch the relatively calm press release after the break, and rest assured we'll be keeping our eyes peeled at CES for new gear based on the spec.
802.11n finalization just a formality, interoperability to be preserved
C'mon, say it with us: "phew!" Considering that just about everyone has been shipping "802.11n" wireless kit since draft 2.0 was put into play two summers ago, we couldn't be more relieved to see the Wi-Fi Alliance confirm that it won't change the baseline requirements of its 802.11n certification program when the format gets certified this September. Just as we'd heard, the WiFi standard will leave its stagnant draft status and sashay into the wondrous realm of officialdom in merely two months, with the updated test program to "preserve interoperability with more than 600 Wi-Fi certified 802.11n draft 2.0 products released since June 2007, while adding testing for some optional features now included in the standard." Good thing, too -- can you imagine the uproar if your forthcoming 802.11n dongle wouldn't play nice with that draft-N router you snagged last June?[Via Electronista]
802.11n should go final by September, just when it's starting to feel slow
It's been a long, long... long time coming, folks. Since 2004, the world at large has been waiting for 802.11n to finally go legit, and while we've been getting along just fine with Draft-N devices, the IEEE is inching closer to completion of the final specification. According to Bob Heile, the chairman of the IEEE 802.15 working group on Personal Area Networks, "802.11 [has been] granted unconditional approval to forward 11n to RevCom," which is currently scheduled to take place on September 11th in New Jersey. He continued by uttering the understatement of the year with "this was an extremely complex project." We won't even bother retracing all the time line slips that we've seen over the years, but we can't help but chuckle at the notion of an ever faster 802.11 protocol to be discussed at the very same meeting. So, let's see here -- 802.11n finally gets its certificate of authenticity after parading around for half a decade as an unfinished draft, and CES 2010 brings about devices based on the even faster 802.11ac. Marvelous.[Via Digg]
SATA Revision 3.0 specification completed and released
Well, it sure took 'em long enough. In August of last year, the Serial ATA International Organization (SATA-IO) got us all hot and bothered when it introduced the SATA Revision 3.0 specification to double transfer speeds to 6Gbps. It's taken until today, however, for that very specification to be completed and released. Thankfully for those who love to relish in the past, the new spec is backward compatible with earlier SATA implementations, and for those looking forward to new innovations, you'll appreciate the new streaming commands for isochronous data transfers between audio and video applications and the Low Insertion Force (LIF) connector for more compact 1.8-inch storage devices. We're told to expect SATA Revision 3.0 demonstrations next month at Computex, but who knows how long it'll be before this stuff seeps into shipping products.
USB 3.0 specification to be formally unveiled this month
We've already got the controller specs, now we just need the full-on protocol specs. Speaking at the Windows Hardware Engineering Conference in Los Angeles, USB-IF president Jeff Ravencraft reportedly stated that he expects the "final specifications to be made public on November 17," and given that said day will mark the opening of the SuperSpeed USB Developers Conference in San Jose, we'd say it all jibes pretty well. Now, how many months will we have to wait before manufacturers can actually get the hasty new ports into machines?
USB 3.0 gets seriously detailed
Just last week, Intel gave AMD, NVIDIA and a whole host of friends what they had been clamoring for: 90% complete USB 3.0 controller specifications. Now, the cool cats over at MaximumPC have churned out an encyclopedic writeup that details USB SuperSpeed remarkably well. The highlights include assurance that USB 3.0 will be backwards-compatible with USB 2.0 and that it'll provide transfer rates up to ten times more than USB 2.0's 480Mbps limit (that's 4.8Gbps). Furthermore, we're told that uploads and downloads are kept on separate lanes, the cables are thicker, it will charge more devices more quickly, and it will be much more mindful of energy waste. Go on and get yourself completely schooled in the read link below.
Intel appeases haters, reveals USB 3.0 controller specification
What's with all the hate, guys? For months now, AMD, NVIDIA and a host of other caps-locked companies have been harshing on the chip maker for withholding critical information in relation to the USB 3.0 controller specification. At long last, Intel can finally throw up its left hand and ask those pundits to talk to it, as the outfit has finally unveiled the Extensible Host Controller Interface (xHCI) draft specification revision 0.9 in support of the USB 3.0 (SuperSpeed USB) architecture. The spec hopes to provide a "standardized method for USB 3.0 host controllers to communicate with the USB 3.0 software stack," and it's being made available under RAND-Z (royalty free) licensing terms "to all USB 3.0 Promoter Group and contributor companies that sign an xHCI contributor agreement." So, are we all happy now?
USB-IF unveils new charging protocol to shorten your wait
While you may be a tad more interested in concepts such as wireless USB or micro-USB implementations, the USB Implementers Forum is kicking out yet another (low key) improvement to the universal serial bus. The crew has now announced the availability of the Battery Charging Revision 1.0 specification, which defines "a standard way for portable devices to draw current from wall chargers or PCs," and furthermore, "allows PCs and hubs to provide increased levels of current in order to shorten the charging time of connected devices." Of course, the task force made sure safety concerns were adequately addressed, as the protocol also defines a mechanism for connected peripherals to detect what type of power source it's mated with and draw an appropriate amount of energy from said host. No word on when nor how the new spec plans on hitting the market, but there's plenty of emergency powering alternatives to snap up in the meantime.[Via TGDaily]
USB-IF announces USB specification for medical field
The competition in the oh-so-lucrative medical field is most certainly heating up as a plethora of physicians are moving from paper charting to electronic documentation, but now we're seeing a battle brewing solely in the connectivity realm. Following Bluetooth SIG's Medical Device Profile, the USB-IF is concocting a working group to "improve healthcare technology" and make the adoption of USB more widespread in the wellness arena. Essentially, the team's initial goal "is to define a USB Personal Healthcare Device Class specification," after which it hopes to implement USB onto devices such as "blood pressure cuffs and exercise watches." Aside from allowing doctors to more easily track and archive changes in a patients history, the added USB connectivity in the hospital ward will purportedly "facilitate the communication between patient and doctor," as home-based clients could easily send their readings directly to a doctor's inbox thanks to the digital interface. Notably, the USB-IF is claiming that the new Personal Healthcare Device Class "should be available for use in devices near the end of 2007," so you better get to training granny on the ways USB -- STAT![Via EverythingUSB]
Linksys touts draft 802.11n gear interoperability
Despite earlier concerns voiced by chipset manufacturer Airgo that draft 802.11n gear will "degrade" or "disable," current 802.11b/g networks, Linksys claims that it has tested and approved its upcoming suite of draft-n routers and adapters for interoperability with current products on the market. Since 802.11n relies on the multiple channel MIMO technology to deliver higher bandwidths, there has been some speculation that pre-N networks would dominate the spectrum designated for 802.11 communications, even though the draft specification specifically requires so-called mixed mode operation. While it's certainly reassuring to know that Linksys has been working with multiple vendors to ensure that current WiFi gear will perform at "peak levels" in the presence of 802.11n signals, the real test will come when we start seeing actual real-world deployment of these speedy new networks.
CES: Blu-ray specification is done, full list of supporters and titles
Well, Blu-ray is done, which I'd hope it would be, what with them announcing players and content and all. If you're interested in licensing the Blu-ray technology you can get in touch with your local Blu-ray licensing agent and execute the secret handshake licensing agreement. Also we've got the complete list of player manufacturers, computer software, and launch titles from Buena Vista Home Entertainment, Lionsgate Home Entertainment Eagle Rock Entertainment, as well as the Japan only content announced so far.
