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?

Even though it's in nearly every phone available, only a few flat panels with integrated wireless networking have surfaced so far, and now LG's packing Bluetooth into its already highly anticipated "infinite black" PG7000 plasma and Scarlet LG7000 LCD models. Pricetags are still in the air, but LG says these flatscreens will hit worldwide starting with Europe in September.

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.

Details around the wireless edition of Sony's Bravia Internet Link kit -- most notably peeped during CES -- are coming into focus. Using that WHDI tech the kids are so into these days, this system is for Sony's Digital Media Extender-equipped HDTVs, and according to Sony Insider will debut for a price between $350 and $500 at the IFA conference in Berlin. Unfortunately, SI's info suggests we may only be spec'd for 1080i streaming of up to 5 feet, a bit less than the 200 foot range originally expected -- for only the fraction of the price of Monster Cables. Punch the read link for the rest of the details on the DMX-WL1T, while the rest of us hope Sony can turn the distance up enough to make it worthwhile.

Wireless HD is having a tough time catching on in the consumer market, but that doesn't mean that things are as dreary in the commercial realm. Fuji Television Network and NTT Corp. are testing out "non-compressed HDTV video transmission using a wireless technology based on the 120GHz milliwave band in live feeds from the Beijing Olympic Games." By utilizing the technology, the duo has demonstrated "simultaneous, wireless transmission of multiple HDTV video channels without delay," essentially enabling camera toting employees to capture footage from more places by being able to walk around untethered. Being able to record spontaneous outbursts from jubilant victors no matter where they are at the Games? Score.

Boy, that's a mouthful, is it not? Shortly after Motorola, Sony and a whole crew of others teamed up to support AMIMON's WHDI wireless standard, in limps Pulse~Link attempting to act like it still has a shot at gaining traction. The left-for-dead CWave wireless-for-HDMI platform -- which is based on UWB (ultra-wideband) -- just received certification by Digital Content Protection as an Approved Retransmission Technology. This, along with the FCC certification received in 2007, enables CWave to start shipping in commercial products. As expected, a couple CWave-equipped Westinghouse HDTVs are slated to hit stores this fall, but it remains to be seen if anything will actually be released to take advantage. Format wars never end pretty, do they?

It'll probably date us, but we remember when Hsu Research subs just made cylindrical subwoofers. Those different-looking reinforced paper tube enclosures were formidable back in the day. Hsu has moved beyond cyinders, but is still turning out the goods for those who crave true sub-woofer tones. The company's latest ULS-15 features a 15-inch driver in a sealed box, and can reach a jaw-dropping (and molar-rattling) 10-Hz in most rooms. The 1,000-Watt amplifier comes in handy for supplying the kind of power necessary for reaching those depths with a sealed enclosure, for sure. The ULS-15 is literally unleashed, as well -- Hsu has added a convenient wireless connection to the unit. Hsu has definitely kept pace with the times, but its pricing is still very attractive -- prices start at $1,299 for a satin black and head northward for more luxurious finishes.

A couple of months back, we asked about options for hooking up rear surround speakers without running wires. For those still on the hunt (and located in the UK), here are two more options. Crystal Audio's TR-100 frees a pair of speakers from wires by providing two transmitters and two receivers, each which pack 100-watts of power. The more affordable TR-60 powers a pair of speakers from one receiver, giving each driver a touch less power. We're told that the units can handle uncompressed wireless transmission of audio and that delay latency is "inaudible to the human ear," but unless you can find these in a local shop to demo, you'll be shelling out £399 ($791) / £249 ($493) in order to see hear for yourself.

There's not much explaining to do once the name of this product is read aloud, but we'll humor you anyway. The recently announced VUDU Wireless Kit is something we dreamed of having when testing the thing out in our own labs, but we suppose late is better than never. The package contains a pair of 802.11g adapters -- one for your VUDU set-top-box and one for your WLAN router -- that creates a "secure, self-contained wireless network" for transferring material from VUDU's servers to your device. The going rate for this bundle is $79, but you can knock $29 from that if you purchase it directly from VUDU with a $299 STB. Now, the real question here is this: will this thing function reliably (wireless HD has been shoved under the rug for a reason, you know), and will it function reliably with HD content. Any guinea pigs out there willing to check?

Shortly after hearing TiVo's top dog speak of a "whole home model" to reduce the amount of STBs required for entertaining individuals in various rooms, along comes Time Warner Cable's chief executive talking up some innovation of its own. We'll be frank -- we're not entirely sure what Glenn Britt is getting at here, but through a broken series of quotes, we're led to believe that the carrier is prepping some "equipment" that will easily bring internet content to TVs. Not like there isn't a perfect solution for this quandary already, but we digress. Specifically, he mentions a " new wireless cable modem that will allow you to network everything in your house," which is about as broad / vague as you can get. Nevertheless, it's enough to keep us watchin', though we can't say our expectations are extraordinarily high. [Disclosure: Engadget is part of the Time Warner family]

Monster Cable -- the firm famous for grossly overcharging for its wares and suing nearly every company on Earth with "monster" in its title -- is going wireless. Yep, rather than gouging customers for Unicorn-like wiring, it'll now be promising to transmit signals through the purest air -- the kind only a Monster box could attract, most likely. Over at Hometech 2008 in Dubai, CEO Noel Lee affirmed that it would soon be "coming out with wireless," also noting that the elusive product(s) would be based on ultra-wideband (UWB) technology and support 1080p. Beyond that, it looks like we'll be waiting for specifics, as an official announcement of the device won't come until the "second week of June." Lee also stated that it "[wouldn't] be inexpensive," and threw out a $600 estimation for "a pair of boxes," while each additional room would cost $200 to connect. Color us absolutely unimpressed.

No sooner do we ask about just how many readers actually give a hoot about multi-channel audio, in comes this. Considering the plethora of folks in the exact same situation, we knew right away it'd made a beautiful Ask Engadget HD question. Without further adieu:

"I recently splurged on a hot new plasma, but now I am looking for a surround sound system to complete the joy. My issue is that I currently live in a rental property, and don't have the luxury of poking holes in walls to set up my system. I know there are a few options out there for people in my position (sound bars, wireless rear speakers, PowerLine?) but I have no idea which gives the best surround sound result. I was looking to spend no more than $2,000."

We'll be honest -- almost anything is possible at $2,000, unless that includes the price of a few (very) nice drivers. We've seen solutions from Rocketfish and a slew of other companies that essentially enable users to add two rear surrounds sans wires when running cabling towards the back proves problematic, but often these are underpowered and flaky at best in actual use. Let us know what you've found to be superior in comments below.

Got a burning question that you'd love to toss out for Engadget HD (or its readers) to take a look at? Tired of Google's blank stares when you ask for real-world experiences? Hit us up at ask at engadgethd dawt com and keep an eye on this space -- your inquiry could be next.

Typically, IDX sticks to making battery systems and portable chargers, but recently, it decided to broaden its portfolio with the CAM-WAVE HD. Essentially, this device is meant to piggyback on cameras (think news crews, sporting events, etc.) and can transmit uncompressed HD signals up to 150-feet (line-of-sight) / 100-feet (through walls). What separates this man from the boys is its ability to beam out full-bandwidth uncompressed HD-SDI and SD-SDI images over short distances with practically no latency, as there's no internal compression slowing things down. Also of note, it's designed to operate in the 5.1 - 5.8GHz frequencies (meaning no unique FCC license is required) and it'll even send those high-def transmissions with encryption to keep snoopers at bay. 'Course, such a swank setup demands a stiff premium, and you'll be looking at a $6,000 bill should you pick up the system in Q3.

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.

Getting HD highlights out of our favorite sports may be getting just a bit easier, now that AOptix has successfully tested a Free Space Optical (FSO) laser communications link to replace traditional fiber runs for an unspecified sports network. With demos from the GM Building in New York and over 3.2Km in San Jose, the company says it can handle up to 10 Gbps,more than enough for uncompressed 1080i or 720p transmissions. Like every other new broadcast tech, it plans for a display at NAB 2008, so just keep in mind the next time the local public access station says they can't broadcast your little snowflake's field hockey game in HD because "there are no HD feeds at the park" they're just not trying hard enough.
