AMIMON's second-gen WHDI spec does full uncompressed 1080p

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.
Sony's taken the crown in the race for thinnest LCD HDTV. At just 9.9mm thick the KDL-40ZX1 nearly halves the depth of Hitachi's former champ (likely throwing up in the bathroom right now) and comes within a whisper of Pioneer's ultra thin concept. Featuring a LED backlighting, a 3,000:1 contrast ratio, 120Hz MotionFlow tech, x.v.Color and BRAVIA Engine 2 image processing this is about as close to a 40-inch window on your wall as is likely to arrive soon. Only one HDMI in is directly on the screen itself, all unnecessary HDMI / USB / component inputs are relegated to a base station, with the option for wired or -- possibly WHDI based? -- 5Ghz wireless (unfortunately limited to 1080i max resolution for now). We'd mention the XMB GUI, AcTVila video on-demand and DLNA support, but at some point it's just piling on. A mere 490,000 yen ($4,474 U.S.) puts the ZX1 on your wall, due at your local Japanese retailer November 10. See you there?

The past few years have seen a wide range of wireless technologies proposed to substitute for the now nearly ubiquitous (at least in terms of new HDTVs) HDMI connectors, but the dust is just starting to settle. Some proposals involve squeezing more juice out of 802.11n. Others rely on ultrawideband technology. Yet another that has many in the industry excited is from SiBeam, which intends to use the 60GHz band to deliver uncompressed 1080p video at 4Gbps. That technology, embraced by a group called WirelessHD, had received the most public support among major consumer electronics companies, with Panasonic, Sony, Samsung, Toshiba and LG listed on its site as promoters (and others listed as adopters).
But WirelessHD is still a ways from consumer availability and recently another wireless high-definition technology has attracted some heavy hitters of its own, including Sony, Samsung, Sharp and the cable set-top division of Motorola. Amimon's WHDI (Wireless Home Digital Interface) is different from many of its emerging competitors because it is designed, like WiFi, to be a technology that blankets the home, whereas most competitors focus on an in-room solution. WHDI even operates in the 5GHz band (like 802.11a and 802.11n), but sheds the costly bandwidth overhead WiFi utilizes to correct transmission errors. In contrast, WHDI is a "video modem" technology that attaches to a device's video output to send uncompressed 1080p video. After that, it's survival of the fittest for the bits.


To help clean up that rat's nest of cables behind your AV rack, semiconductor company AMIMON is now shipping its Wireless High-definition Interface (WHDI) chips to manufacturers. Loewe and Funai will be demoing WHDI products such as wireless HDTVs and high-def DVD players at IFA in Germany next week, following up on the WHDI-equipped projector prototype Sanyo showed off at CES. The chipset supports streaming uncompressed 1080p over the unlicensed 5GHz spectrum -- with worldwide compliance up to 1080p / 30fps -- at ranges up to 100 feet (30 meters) and a latency of less than 1ms. Let's hope you can handle the dust bunny apocalypse you'll release from behind the stereo.
