An HTPC Perspective on home theater PC technology
We conducted a reader survey a few weeks ago, and one of the tech topics that received a surprising amount of interest in was HTPC coverage. You, our awesome readers, wanted to know more about the hardware and software behind them. I’ll admit that I was ardent about the prospects of talking HTPCs with you. As a relatively new entrant to that area of tech myself, I was excited to cover it, and give you more coverage on a topic you wanted to see more of!
Today we won't be talking about home theater PCs in the sense of a computer in the living room AV rack (Ryan covered that earlier this week), but rather a related technology that makes the HTPC possible: the CableCARD-equipped TV tuner.
I will forewarn you that this article is quite a bit more informal than my usual writings, especially if you only follow my PC Perspective postings. In the future, it may not be that way, but I wanted to give some backstory and some personal thoughts on the matter to illustrate how I got into rolling my own DVR and why I’m excited about it (mainly: it saves money and is very flexible).
Despite my previous attempts to “cut the cord” and use only Internet-based services for television, me and my girlfriend slowly but surely made our way back to cable TV. For about a year we survived on Netflix, Hulu, and the various networks’ streaming videos on their respective websites but as the delays between a shows airing and web streaming availability increased and Netflix instant Streaming started losing content the price of cable started to look increasingly acceptable.
She was probably the first one to feel the effects of a lack of new content – especially with a newfound love for a rather odd show called True Blood. It was at some point thereafter, once she had caught up with as many seasons offered on Netflix of various shows as possible that she broke down and ordered U-Verse. U-Verse is an interesting setup of television delivery using internet protocol (IPTV). While we did have some issues at first with the Residential Gateway and signal levels, it was eventually sorted out and it was an okay setup. It offered a lot of channels – with many in HD. In the end though, after the promotional period was up, it got very expensive to stay subscribed to. Also, because it was IPTV, it was not as flexible as traditional cable as far as adding extra televisions and the DVR functionality. Further, the image quality for the HD streams, while much better than SD, was not up to par with the cable and satellite feeds I’ve seen.
Being with Comcast for Internet for about three years now, I’ve been fairly happy with it. One day I saw a promotion for currently subscribed customers for TV + Blast internet for $80, which was only about $20 more than I was paying each month for its Performance tier.
After a week of hell Therefore, I decided to sign up for it. Only, I did not want to rent a Comcast box, so I went searching for alternatives.
Enter the elusive and never advertised CableCARD
It was during this search that I learned a great deal about CableCARDs and the really cool things that they enabled. Thanks to the FCC, cable television providers in the United States have to give their customers an option other than renting a cable box for a monthly fee – customers have to be able to bring their own equipment if they wish (they can still charge you for the CableCARD but at a reduced rate, and not all cable companies charge a fee for them). But what is a CableCARD? In short, it is a small card that resembles a PCMIA expansion card – a connector that can commonly be found in older laptops (think Windows XP-era). It is to be paired with a CableCARD tuner and acts as the key to decrypt the encrypted television stations in your particular subscriber package. They are added much like a customer-owned modem is, by giving the cable company some numbers on the bottom of the card that act as a unique identifier. The cable company then connects that particular card to your account and sends it a profile of what channels you are allowed to tune into.
There are some drawbacks, however. Mainly that On Demand does not work with most CableCARDS. Do note that this is actually not a CableCARD hardware issue, but a support issue on the cable company side. You could, at least in theory, get a CableCARD and tuner that could tune in On Demand content, but right now that functionality seems to be limited to some Tivos and the rental cable boxes (paradoxically some of those are actually CableCARD-equipped). It’s an unfortunate situation, but here’s hoping that it is supported in the future. Also, if you do jump into the world of CableCARDs, it is likely that you will find yourself in a situation where you know more about them than the cable installer as cable companies do not advertise them, and only a small number of employees are trained on them. Don’t be too hard on the cable tech though, it's primarily because cable companies would rather rent you a (expensive) box, and a very small number of people actually know about and need a tech to support the technology. I was lucky enough to get one of the “CableCARD guys,” on my first install, but I’ve also gotten techs that have never seen one before and it made for an interesting conversation piece as they diagnosed signal levels for the cable modem (heh). Basically, patience is key when activating your CableCARD, and I highly recommend asking around forums like DSLReports for the specific number(s) to call to get to the tier 2 techs that are familiar with CableCARDs for your specific provider when calling to activate it if you opt to do a self-install. Even then, you may run into issues. For example, something went wrong with activation on the server side at Comcast so it took a couple of hours for them to essentially unlock all of my HD channels during my install.
