Aw, now isn't this just the sweetest thing you've ever seen? Cox has found the generosity to not only send out information to let Phoenix, Arizona subscribers know about the forthcoming implementation of SDV (July 1st, if you're wondering), but to promise a free tuning adapter to CableCARD-using TiVo Series3 / HD owners to boot. In all seriousness, we only wish every other cable company out there would handle this situation in a similar manner, but things just can't be this easy everywhere, right?

This one probably goes without saying, but just in case you're inclined to waste a few gallons of precious regular unleaded searching for a tuning adapter, don't. The National Cable & Telecommunications Association (NCTA) and TiVo have jointly issued a release to inform the public that "several manufacturers of switched digital external tuning adapters have submitted products for formal testing at CableLabs." On the positive side, this means we're inching closer to seeing these devices hit store shelves, but sadly, it also means we're not done wading through red tape just yet. For those unfamiliar, these newfangled "tuning adapters" will enable TiVo Series3, TiVo HD and certain one-way set-top-boxes that utilize CableCARDs to "access digital cable channels delivered using switched digital (SDV) technology." Hit up the read link for all the details, and check out our hands-on galleries with a few of the boxes right here.

The highlight of The Cable Show for us was actually to be able to see the Motorola Tuning Adapter in action. Sure it isn't that exciting of a product, but just the idea that our beloved TiVo won't be useless because of the fact that all latest HD channels are being deployed with SDV (Switched Digital Video) is enough to get us going. The MTR700 was named before CableLabs renamed the class of product from Tuning Resolver to Tuning Adapter, and should be available to cable companies in July. Unfortunately there's really no way to tell how long it'll take before your provider makes it available to you, or for how much. For the most part, there's no change from a user's perspective, so much so that for the demo the channels were relabeled so we could tell which were SDV, and which weren't. In fact the only way you can even tell this thing is connected, is because the TiVo's Devices menu has a new option with a whole slew of troubleshooting options for the cable guy. Changing channels was just as fast -- or slow depending on your perspective -- as a TiVo HD tuning standard HD broadcast channels.

Despite the fact that Switched Digital Video will allow HD providers to bring us more HD goodness, it's been a bad word around here because it prevents TiVos in Vista Media Centers from access the new HD. But with the Cable Show and the first public display of the Tuning Adapter -- formerly known as the tuning resolver -- right around the corner, TiVo fans can see the light at the end of the tunnel. But at the same time, with no word from Microsoft or AMD, Vista Media Center users with ATI Digital Cable Tuners are on the edge of their seats. So we decided to hit up AMD and CableLabs for some answers, and while we didn't hear exactly what we wanted to, the response was promising. According to AMD it's "in discussions with all the relevant parties to address the issue of Switched Digital Video" and CableLabs was quick to respond by saying "the CableLabs specifications for the Tuning Adapter and the UDCP application extension do not technically prevent use with an OCUR." Of course all this really amounts to is a definite maybe, but we're optimistic we'll see this happen.

Earlier this year, we got word that switched digital support for CableCARD was still on track for Q2, and now we're feeling a tad more confident in said assertion thanks to a recent update from Motorola. According to the company's Mari Silbey, its own tuning resolver -- which is meant to allow any third-party CableCARD device to access channels delivered via SDV -- will officially be christened MTR700. Additionally, we're told that it'll likely look just like the DCT700 set-top-box (pictured), and that the unit has just passed through a CableLabs interop "with flying colors." Next, we're expecting the device to be submitted for CableLabs' Cert Wave 60, and best of all, Moto assures us that the STB will be on display (and "functional" enough for demos) at next month's Cable Show in New Orleans. Huzzah!

Cablevision is making the move to switched digital video, with its 15 Voom HD channels going SDV-only in April and May. Of course this means that CableCARD users won't be able to get them any more. There were around 14,000 such devices on Cablevision as of last December, most notably Tivos, so the company is offering a free HD set-top for a year. While not the most elegant of solutions, it should at least tide people over until the tuning resolver that fixes this gets sorted out. Of course, maybe the Voom HD channels aren't important to every viewer, but others will inevitably follow and the offer is set to expire June 30. Such is life on the way to 500 HD channels, we suppose.

Hi-def and DVRs go together like peanut butter and jelly, but even with all the great DVRs available today, none are perfect. TiVo offers the best overall user experience and features, but lacks a few fundamental features that most cable STBs have -- like VOD, for starters. Although this isn't TiVo's fault, when it comes down to figuring out what's right for your family, it really doesn't matter. During Tivo's earnings call yesterday, it was reaffirmed that TiVo is working one step closer to making the ultimate cable DVR by including two-way functionality using the latest CableLabs standard tru2way. For those who haven't been keeping track at home, tru2way has undergone an identity crisis, and if you go back long enough, you'll find that it was called CableCARD 2.0 -- by someone. The way this would work is that you'd have a way on a TiVo to access the cable company's UI, so good or bad, when you're accessing VOD content, you'd see the same thing as if you were using a Moto or SA Cisco box. What isn't known is if current HD TiVo owners, with the help of a tuning resolver and some software, would have access to the same features. We don't see why not, but this stuff is already way more complicated than it should be, and at this point we wouldn't put anything by CableLabs.

The biggest challenge content providers face today is bandwidth. Their customers are demanding more HD, but their network is tapped out. There's no silver bullet, but there are multiple small solutions that all add up. SDV or Switched Digital Video, is one of those and promises to free up to 50% of the utilized bandwidth by only sending the channels that're being watched rather than all the channels, all the time. Unfortunately there's a catch, not only is SDV currently incompatible with 3rd party CableCARD hosts, but to really see the benefits, cable has to reduce the number of subscribers per node. Current service groups are around 1000, but to really take advantage of SDV, the ratio between channels and subscribers needs to be closer to 1:1; so they'd have to deploy four times as many nodes to get there. Currently providers are just doing trials with SDV, but we can expect to see it widespread in 2008. Lets just hope they get that Tuning Resolver thingy ready by then.
