It's hard to say if ultra-wideband (UWB) will catch on (or get squashed by WHDI) in the wireless HD realm, but the applications for UWB outside of your living room are still many. Researchers at Virginia Tech have reportedly "developed an efficient compact ultra-wideband antenna (CUA) for a range of home, automotive, medical, and military applications," and according to inventory Taeyoung Yang, it has "achieved a near optimal performance for size and bandwidth." Better still, the design is said to be "cheap and simple to produce," which makes us hopeful for embedded wireless devices (receivers, STBs, Blu-ray players, etc.) sooner rather than later. We can't say for sure if this stuff is any closer to taking off in the mainstream, but at least we're making progress somewhere.

While it was Pulse~LINK winning the last (but obviously not final) round of this multi-year tiff, the tables have turned once more. Tzero Technologies has just announced that the US Patent Office "issued an office action rejecting all claims of US patent number 6,970,448 asserted in a lawsuit brought by Pulse~LINK against Tzero in June 2007." This decision, coupled with a stay issued by the district court, will evidently bring the lawsuit to a close "for the foreseeable future." We're told that the legal struggles between the two are now officially over, but we're admittedly hesitant to believe it.

We knew Hitachi's Ultra Thin HDTV family would boast ultra-wideband technology, and while little was said about this aspect during CES, we've now learned that Tzero will be responsible for handling the aforementioned UWB duties. As expected, the UT HDTVs will "be able to receive high-definition video wirelessly from any HDMI equipped audio / video component," as Tzero promises that users will see transmission speeds of up to 480Mbps. Interestingly, we're told that the UWB-equipped sets are available in Japan right now, but only time will tell if those luscious wireless abilities will make the trip stateside in Q2.

If you're looking to pick up any UWB device to stream high definition video / audio around your crib anytime soon, chances are it might have a little Taiyo Yuden and Sigma Designs beneath the shell. The two firms are showcasing a WiMedia Alliance-based UWB wireless HD streaming solution here at CES, which highlights "Taiyo Yuden's antenna array on its mini-PCI reference design module with Sigma Designs' Windeo chipset." The unique three-antenna array offered on Yuden's solution supposedly offers up extended range possibilities, and fully supports Sigma's "Intelligent Array Radio" technology. Unfortunately there's no word on any end product uses just yet, nor any expected dates for this newfangled system to hit the mainstream, but with the ginormous pressures being felt around here to get wireless HD streaming out to consumer, we're sure it's pretty high up there on each company's priority list.

Looks like CES 2007 is the place to be for wireless HDMI, as now we've seen offerings from AMIMON, Philips, and Tzero showcasing the ability to stream beautiful 1080p HD sans wires, and now Asus is joining the fold. Apparently basing its self-branded product line on technologies from Tzero and Analog Devices, the admittedly vague press release simply informs us that the company will be fighting tooth and nail in the wireless HDMI over UWB arena, and notes that we'll be seeing "accessory devices and embedded designs that dramatically simplify connections between home audio and video electronic components." Per usual, Asus' box will accept component, composite, S-Video, and HDMI (HDCP-compliant) signals, and the video is then compressed using Analog Devices' ADV202 JPEG2000 video codec, where it's then combined with audio, packetized and encrypted, and transmitted via the Tzero MAC and PHY chip. So until we can mosey on over to see some of this stuff in action, we'll just have to take Asus' word for it, as the company withheld information regarding model numbers, prices, and release dates for the time being.

Philips has announced its showing off a wireless HDMI product, based on Ultra Wideband at this year's CES. With enough bandwidth to send an uncompressed HD stream of up to 1080p resolution, the company claims its solution solves the problem of arranging components and display devices without affecting the A/V experience. The ultra wideband frequency range should keep it free from interference caused by cell phones, WiFi or microwaves. Oddly, the press release continually refers to the SWW1800 as a "wireless cable", which would likely explain the dearth of available pictures as they try to find a way to photograph it. We'll have to see if we can get a look at it on the CES show floor, but the company expects to debut it in May with an MSRP of $299.

Update: We've got a picture of the wireless adapters from Philips' press conference yesterday, where they were pretty tight lipped about availability, pricing or specifics on the technology, but later issued a press release with two of the three.
