SDV Keeps On Rollin’

Dave Zatz —  August 24, 2007

In the next month, Cox will deploy SDV in neighboring Fairfax (VA) county. Multichannel News writes:

In Northern Virginia, where Cox has about 240,000 subscribers, the SDV system will go live systemwide in about 30 days, according to Kelso. Later this year, Cox plans to roll out the system in its Phoenix and Orange County, Calif., systems. Cox is the third major cable operator to publicly acknowledge using BigBand’s SDV.

Obviously the concern for many TiVo customers, and others with commercially available CableCARD set-top boxes or televisions, is that switched channels can’t be viewed. Supposedly folks are at work on this issue, which will only become more prominent as both CableCARD  and SDV penetration increases. I hope a solution can be worked out in a timely manner without the FCC stepping in, but I’m not feeling optimistic…

Building the perfect DVR/video-entertainment device is hard, which is why cable or telco TV plus a Netflix or Blockbuster + Movielink service is probably your best bet right now. But lest ye be sitting in your living room bemoaning the state of your set-top set-up, let me offer up a bit of context on why building the perfect box is so hard.

There’s the leased set-top model used by cable operators. In an effort to make those set-tops as cheap and efficient as possible, a lot of constraints are applied. There can’t be too much storage or processing power, too many added features or too much open access for modification that could muck up the service for everyone. Not an ideal situation, but on the other hand, these operators bring DVR to the masses.

There’s the retail model, which is owned by TiVo. People who have TiVo tend to love TiVo, but relatively few people have it because of the price. Plus, there’s the issue of plugging TiVo into your cable or telco network. Either you need a separate set-top from your service provider or you need a CableCARD. CableCARD certification is a serious technical challenge (more than I think most people realize) and it still doesn’t provide access to two-way services like video-on-demand and switched digital video.

Finally there’s the Internet model. All those media extenders that made big news early in the year, and P2P services like Joost (the box here being your computer). Here the problem is both content and bandwidth. Not enough appealing, timely content to keep people happy, and/or not enough bandwidth to keep content flowing efficiently.

So what’s on the horizon? Continue Reading…

A periodic roundup of relevant news… from our other blogs.


It’s that time of year again. We’re more than halfway to the holiday shopping season and CES 2008, which means CE companies are starting to panic about what they can get on to store shelves or at least out of production in time to take advantage of the year’s biggest buying season and biggest PR event respectively. Without doing any in-depth research yet, here’s my list of what we might see around Black Friday time:

Retail Moxi DVR – Dave’s already covered this extensively, and I can’t wait to see how Digeo brings its two models to market. What are the price points? Who will sell them? Has Digeo had any problems with CableCARD certification?

Touchscreen iPod/Nano iPhone – The rumor is some iPod/Nano mash-up will come out later this year. I don’t think it will make my X’mas wish list. A touchscreen on a device smaller than the existing iPhone? I’d need tinier thumbs.

twc.jpgBen Drawbaugh over on EngadgetHD reports that Time Warner Cable will be deploying switched digital video (SDV) to 50% of its markets before the end of 2007. That’s great news in the sense that SDV should free up significant bandwidth. Like analog reclamation, SDV will make it possible to offer more HD content as well as new apps like Time Warner’s Start Over service.

Unfortunately, as Ben points out, SDV is not great news for TiVo Series3 (and potentially stand-alone Moxi) owners. Today’s CableCARDs only permit one-way communication (technically that’s not exactly true, but for all practical purposes it is), which means TiVo customers won’t be able to access switched content, including any new HD channels.

Two-way CableCARDs are coming, but not quickly enough. Despite the fact that cable operators may be getting two-way cards in time for the 7/07 deadline (they need them for VOD services as well as SDV), those cards haven’t been certified for retail devices. Sorry TiVo customers — you’ll have to wait for CableCARD 2.0 and refresh that hardware.
