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.

Be still, our hearts! After watching the wireless HD / HDMI sector fumble along for years on end, a team of mega-corps have finally agreed to push their self-interests aside and collaborate on a standard. WHDI creator AMIMON has joined forces with Motorola, Samsung, Sony and Sharp in order to form "a special interest group to develop a comprehensive new industry standard for multi-room audio, video and control connectivity" utilizing the aforementioned Wireless Home Digital Interface technology. Reportedly, the group will have a standard completed before 2009 dawns, but we all know how easily these things can get pushed under the rug. Nevertheless, the overriding goal here is to "enhance the current WHDI technology to enable wireless streaming of uncompressed HD video and audio between CE devices such as LCD and plasma HDTVs, multimedia projectors, AV receivers, DVD and BD players, set-top-boxes, game consoles and PCs." A tall order, sure, but one we're elated to see taken on. Full release (and promo spot) after the break.

Remember those "world's thinnest" X-Series LCD HDTVs we spotted earlier this year? On their way over from Japan to the US, Sharp has whipped up a partnership with AMIMON in order to offer a wireless HDTV link based on the latter company's WHDI technology. Apparently the 37-, 42- and 46-inch displays will be sold in both nations with an optional wireless video transmitter (read: each set is "wireless ready"), giving users the ability to send uncompressed HD to their HDTV from up to 100-feet away. As for US pricing and availability, Sharp's not quite ready to dish out those points, and while we're not exactly sure if this is the launch that finally gets wireless HD headed in right direction, it certainly can't hurt matters. Full release posted after the jump.

As the war between wireless HD solutions heats up, AMIMON is looking to make a splash by partnering up with Belkin. Reportedly, the firm's Wireless High-definition Interface (WHDI) -- which was just recently HDCP certified -- will be the heart of the Belkin FlyWire aimed at streaming HD DVD / Blu-ray (among other uncompressed content) to television sets sans wires. Unfortunately, little more is known beyond that (aside from the price range, set at $499 to $599), but here's to hoping that we'll get a closer look in just a few days.

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.

Okay, so we had a sneaking suspicion that this whole "uncompressed streaming of high definition video sans wires" was a bit too good to come true at CES 2006, but once again AMIMON is promising to showcase its WHDI (wireless high definition interface) at next week's Vegas extravaganza. Providing a little backbone to the claim is Sanyo, which is slated to showcase the "world's first wireless HD projector" using AMIMON's technology. The demo will utilize a yet-to-be-named Sanyo PJ and will reportedly beam unadulterated imagery via an "802.11a/n RFIC chipset" from an HD DVD player without the help of wires, and the quality should look exactly the same as if you were using a DVI / HDMI cable. Current developer platforms allow connections from any device outputting in HDMI, component, S-Video, composite, or VGA, and WDHI operates in a "5GHz unlicensed band" which enables video streaming "of up to 3Gbps" from 100 feet away. Sure, even today this still sounds mildly unbelievable, but if both firms keep their word, we'll be seeing just how truthful these bold claims are in a matter of days.
