SiBEAM founder says WirelessHD is best for "in-room" applications
by Darren Murph posted Dec 10th 2008 at 8:40AM
While AMIMON is busy gloating about its 100,000th chipset shipment, WirelessHD is quietly lurking in the background waiting to exploit a niche of its own. In a rather telling interview, SiBEAM founder John Marshall (pictured) confessed that it was going after a different market rather than taking on the WHDI (and similar) format directly. He stated that its milliwave'-based WirelessHD technology -- which just received a cash infusion from Panasonic and Samsung -- "targets in-room use, whereas the others target whole-home use." He continued by noting that it "limit its use to inside a room to make the most of milliwave's properties, without assuming content transmissions through walls." Finally, we're led to believe that certain partners will be making product-based announcements at CES 2009, though judging by the history of cord-free HD, we wouldn't expect anything to start shipping right away. Or ever, even.Researchers develop world's smallest ultra-wideband antenna

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.US patent office supports Tzero, rejects Pulse~LINK patent

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.Hitachi's Ultra Thin LCD lineup to boast Tzero's UWB technology

Taiyo Yuden and Sigma Designs showcase WiMedia-based UWB HD streaming
by Darren Murph posted Jan 9th 2007 at 4:47AM
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.Asus launches its own wireless HDMI over UWB offerings
by Darren Murph posted Jan 8th 2007 at 7:25PM
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 intros Wireless HDMI
by Richard Lawler posted Jan 8th 2007 at 6:39AM 
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.
