Although QuantumPhonic's QR technology is emerging a touch late to make a difference at the Beijing Olympics, it certainly has its sights set on zapping excess noise at the 2012 Summer Games in London. In a rather excited and somewhat unprofessional release, the aforementioned company has announced a technology that can seemingly kill the echo and reverberation that almost always sour the audio experience in large arenas and stadiums. Of course, it also claims that the tech "defies all feasible common sense and design," so believe at your own risk. If you're terribly interested in learning more, there's an immensely entertaining video waiting just after the break.

Light control is probably the biggest challenge to a good projection setup. The subterranean nature of London's subway is pretty much ideal in that regard, and now CBS Outdoor has brought its cross-track projection (XTP) system to the Tube. The Piccadilly Circus, Euston, Bank, Liverpool Street and Bond Street stations have been outfitted with a total of 23 14-foot screens that are getting HD video ads beamed onto them, sans audio (thankfully). There are plans to build out to 150 XTP screens and compliment them with 2,000 digital screens Tube-wide, which all fits in with CBS Outdoors' plans to bathe subway riders in advertisement. If ad-targeting tech is brought into the equation, we see some potential for really embarrassing hilarity. Meanwhile, London readers are encouraged to let us all know how the picture XTP quality is holding up!

For the attentive in attendance, you likely noticed that none of Toshiba's newly announced laptops (yes, even the absurdly powerful Qosmio rigs) have built-in Blu-ray drives. Like, there's not even an option. When questioned about the obvious oversight (ahem), Tosh's Europe CEO Alan Thompson noted that "Blu-ray was just one of the many ways that you can get HD content and is not required for accessing HD content." Furthermore, it seems as if the outfit is continuing on in its pursuit to develop the best DVD upconverting technology in the whole wide world, as it explained to the press in London that its forthcoming technology would "fill in the gaps" and "add resolution." Company representatives even remarked that "Blu-ray was only a storage medium," and reiterated that BD "wasn't the only way to view high-def content." It's one thing to bow out gracefully, pick up the pieces and get on with life. It's another thing to douse yourself in ignorance and pretend that Blu-ray (let alone HD DVD) never happened.

It's official: HD aficionados in the UK will soon be able to get their fix via Freeview. If you'll recall, the Freeview HD trial that took place in 2006 went over quite well, and according to Ofcom, up to four free HD channels will be broadcast. Unfortunately, users looking forward to such niceties will be forced to wait until analog is switched off in their neck of the woods, and of course they'll also need an HD-ready TV and a new set-top-box. We've already heard that BBC will be one of the four channels, and ITV, Channel 4, Five and Welsh network S4C have all been "invited to bid for [the other] three slots in which they can broadcast high-definition TV or other new services." On the upside, the whole of the country should be digital by 2012, just in time for the London Olympics -- and for those lucky souls in and around Whitehaven, you'll get the spoils first.

Remember those absurdly expensive (and extraordinarily desirable) Artcoustic speakers we peeked last month? If you're a few bucks short of being able to acquire your own, you may still be able to get a taste of what they offer. For guests checking into the 5-star Radisson Edwardian Hampshire Hotel on London's Leicester Square, you can take a listen to the various Diablo monitors and DFS100-75 / DFS75-55 subwoofers that are placed throughout the hotel's reception area, lobby and hallways. Sadly, there's no word on whether or not suites have been equipped with any Artcoustic kit, but c'mon, you know you'll be spending your free time in the main foyer just hoping to see Baby Spice prance through.

BBC is smack-dab in the middle of the HDTV trails over in London but that isn't stopping them from adding to their high-def lineup. The plan is to simulcast recently launched programs such as Robin Hood, The Amazing Mrs. Pritchard, and Torchwood along with the SD broadcast. The station is adding additional HD programming later in the year as well but we won't run down the entire long list which should suffice to say there is a bunch of new HD shows coming. Apparently the trial is going well otherwise we don't think the BBC would be dropping more cash for additional programming.

Hotels are suppose to feel like home away from home but sometime those non-detachable coat hangers just make the place seem so, um, staged, but if need to get your high-def fix when travel abroad, check out London's Four Seasons on Canary Whalf. NXTV has outfitted 142 rooms with high-def VOD along with high speed Internet, and a customized guest interface. We are wondering what kind and size HDTVs these rooms are outfitted with...wonder if Weblogs INC will foot the bill to fly the four of us over there to check out the rooms HDTVs?

Remember a few weeks ago when we talked about the BBC trials? Well, the network is taking applications for the trial that will take place in London. So, not to state the obvious, but you have to live in London and the not so obvious is that you have to have Freeview. The network will then provide a select couple hundred households with set top boxes to receive the signal.

Not sold yet London residents, this trial would allow you to watch the coveted World Cup games...
