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.

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.

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.

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.

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.
