TZero closes up shop, UWB all but dead
It's been a slow, painful death, but it's about time to just pull the white sheet over ultra-wideband and let the wireless standard rest in peace. After Intel pulled its support for UWB and proponent WiQuest shut down late last year, all that the format really had left was TZero. After successfully surviving some legal issues, we thought the company was good to go in fighting a hopeless battle against wireless HD upstart AMIMON. Now, it seems that WHDI (that's AMIMON's magic) is free to take the market by storm, but only time will tell if wireless HD is even remotely close to mainstream. In one sense, we're sad to see competition die, but on the other hand, it's always good to see fruitless format wars fade away. Don't be too down on yourself, TZero -- it's not like anyone really had high expectations for you or anything.
CNET tests out Gefen's EXT-WHDMI wireless HDMI extender
CNET took the Gefen EXT-WHDMI out for a spin, and came back with an overall good impression of the $800, Tzero-based solution for breaking free of HDMI cable runs (at least within a 30-foot radius). Once the automatic input switching was mastered and video sources were set to conform to the unit's 1080p/24 upper limit -- 1080p/60 is not supported -- the unit generally turned in respectable performance. Of course, comparisons to Sony's similarly priced DMX-WL1 were warranted, but neither unit scored a knockout blow. We'll let you hit the read link for the gory details, but rest assured that the Gefen unit didn't drop any frames or otherwise wreck the image quality. For the asking price, you'd expect nothing less, but there were some caveats -- we agree with CNET's bottom line of picking one up from a dealer with a good return policy in case it doesn't all work out for you; that $800 will buy extenders and a lot of cable, after all.
ZeroWire 2.0: Wireless 1080p for less than $50 per device
Apparently through with its legal issues, Tzero's decided now is the time to show its second generation UWB-based wireless HDMI technology. ZeroWire 2.0 is sending out 1080p (24/56/30/60fps) video with 16ms or less "sub-frame latency" suitable for lag-free high definition gaming, 7.1 audio support, and 480Mbps transfer rate with ranges of greater than 20 meters. The most important number is a $50 per unit price, with all that wireless magic performed via UltraMIMO signal technology and h.264 compression (replacing the old JPEG2000 system seen in Hitachi's Wooo HDTVs and Gefen wireless extenders) in the TZC7200 chipset. Impress Watch caught one of the demos currently going on in Japan and were told this is well below the price of other technologies like Wireless HD and WHDI, while enjoying wirelessly connected gaming on conveniently located PlayStation 3 consoles. With the previous generation's external antennas also getting the ax, we'll see if a leaner, cheaper technology can stand up to the competition (and convince us there's a reason to play Rock Band from way across the room) next year.

Gefen's UWB / WHDI-based wireless HD solutions face off at CEDIA
After last night's discovery that Gefen was proudly supporting both Tzero's UWB technology and AMIMON's WHDI alternative, we just had to stop by and see if it was true. After chatting it up with a company representative, we discovered that Gefen is indeed introducing two new wireless HD products, each of which uses a separate technology. The Wireless for HDMI Extender (UWB) was seen sporting a black outfit, and we were told that it'll ship in about a fortnight for $800; the WHDI-based GefenTV (that's the pair in silver) will begin shipping "later this year" for around a grand. When directly asked if Gefen had any plans to choose one protocol over the other, the rep simply stated that Gefen would be riding things out and supporting both until one took over. %Gallery-31290%
Gefen hedges its bets, announces UWB and WHDI-based wireless HD solutions
For awhile now, ultra-wideband (UWB) has been on the way down in terms of popularity, and all the while, AMIMON's WHDI technology has been racking up an unprecedented amount of support. At this year's CEDIA conference, we've got adapter manufacturer Gefen backing both sides by introducing separate wireless HD solutions built around Tzero's UWB tech and the aforesaid WHDI. It's hard to say if both of these formats will continue to be supported (though if we had to guess, we'd say WHDI has the upper hand), but at least for now, Gefen's playing it safe rather than casting a vote. We've a term in Washington for your kind, Gefen, and that term is fencesitter.Read - Gefen supports WHDI!Read - But wait, Gefen supports UWB!
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.
Federal court ratifies Pulse~LINK UWB patents in Tzero case
At long last, it seems the legal spat between Pulse~LINK and Tzero has come to an end. Federal courts have ratified the former company's patents in a UWB-over-coax patent infringement case against Tzero, affirming that Tzero will now have to pay licensing fees to use Pulse~LINK's technology. In the settlement, it was noted that Tzero had "suspended development of products that were the subject of the legal action," and if it chose to re-introduce any of those wares, it would first cut a check to Pulse~LINK. Time to hug it out? Nah, we thought not.
Hitachi's Ultra Thin LCD lineup to boast Tzero's UWB technology
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.
Tzero's WiMedia-based ZeroWire uses UWB for HD streaming
While Tzero has been at the forefront of ultra wideband technology for some time, the firm is upping the stakes even higher with its WiMedia-based TZC7200 ZeroWire chipset. The UWB semiconductor solution was designed to deliver "real-time high-definition video" either wirelessly or over cabling, and can even open new doors for "distributing entertainment content throughout the entire home using existing coax." Reportedly, this device can pipe multiple streams of HD video through your average cable network at the tune of 480Mbps, and it boasts application integration including IP, UDP, TCP/IP, multicast, and unicast. Notably, ZeroWire is "comprised of both a Radio Frequency IC (RFIC) as well as a baseband and media access control system-on-chip," and while the chipset is listed is being available immediately, you'll need to contact Tzero yourself to fetch the pricing details.
Asus launches its own wireless HDMI over UWB offerings
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.
Wireless HDMI over UWB? Heck yes!
Some buzzwords just sound good together. Like robots and flamethrowers -- those two just hit it off right from the start. Now Tzero Technologies and Analog Devices are teaming up for a new standards-based wireless HDMI tech that marries UWB with everybody's favorite home theater plug. Tzero is bringing the UWB to the table, while Analog Devices' is sharing their JPEG2000 video codec. A UWB transmitter compresses all the HDMI data on the way out of a video device and a receiver converts it back to HDMI on the way back into your display. With a range of 30 meters, and no line of sight requirements, all sorts of diabolical home theater configurations become possible. For instance, we can envision a ceiling mounted projector without all the wiring, or a noisy HTPC hidden away without similar hassles. According to Tzero, the first adapters should be out in a couple of weeks, and the price should be "similar to other WiFi devices." We'll be sure to test out the performance before we jump in with two feet, but if the price is right we're liking where this wireless HDMI thing is headed.[Via Cnet]
