Are You Being Cheated by Digital Cable?
Lauren Weinstein writes "Even though your cable company may claim that a channel is in a digital tier that you're paying for, they may be sending it to you in analog form, with associated negative effects. Surprise! Are You Being Cheated by Digital Cable? 'You're paying for digital, you should get digital. Outside of the lower video and audio quality that can be present on many analog feeds, third-party devices (like cableCARD TiVos) which could otherwise record a digital signal directly, will be forced to re-digitize an analog signal, with inevitable quality loss in the process. But how to know for sure if a channel is digital or analog as received?'"
I agree, that comment did little more than restate part of the summary and didn't add anything to the discussion.
We definitely don't want comments like that on Slashdot.
Why does everyone assume digital means better? In my experience "fuzziness" with cable is usually cause by horrible wiring (no grounding, split many times, etc.) within a house/apartment, not an inherently bad signal. Cable companies still have a significant portion of their customers using the analog signals because they either don't have digital cable or have more than one TV but don't want to have multiple cable boxes. Thus, the analog signals tend to be relatively clean. The purely digital channels, on the other hand, look to be encoded at such a low bitrate that one can easily see macroblocks continuously.
Disclaimer: As mentioned before, I do work for a cable company.
Americans can get their traditional TV through a number of different providers, but it boils down to just a few methods of delivery: direct from the broadcasters over the air, from a satellite, via fiber owned by a telephone company, or via a hybrid fiber/coax network owned by a cable company. Of these options, cable providers are caught in the crossfire of regulatory demands and consumers who don't know enough about the technology itself to know what they really want. You never hear these complaints about satellite/FTTH (FiOS), only because the nature of their medium requires all digital transmission. But is 100% digital always "better" for the consumer? The answer is clearly no, not always.
As I'll explain later, much of the FCC's time is spent regulating the coax providers to help the "smaller players". Really, now...AT&T and Verizon are small players? When will the FCC step in to help the smaller players in the landline voice business, such as Vonage and VOIP? (Hint: they won't.)
Cable has been the incumbent for so long that they have become the Microsoft of TV. If there is any complaining to be done, lets complain about the cable company. But as I said, most consumers don't know what they are complaining about. Let's look at the ramifications if every cable company switched to 100% digital tomorrow...which seems to be to be what people want. Let's do a step by step breakdown:
The infrastructure in most cable systems does not need a rebuild for digital, just a little headend work and some maintenence in the field to fix issues that will visibly affect digital but not analog (CPD, microreflections, etc...). So, BAM! Cable is all digital. What happens the next day?
Firstly, ALL TV's without a digital tuner go dark. Great-aunt Maryrose and Gramma Clara turn on their perfectly good 1988 Zenith, and get static. They now have to go buy new TV's to use cable service, because consumers demanded digital transmission. In fact, this WILL happen when the OTA conversion happens in 2009, but OTA viewers may get subsidized boxes. (It will be interesting to see the FCC enforce the separable security statute with that one.) Cable companies get to eat the cost. In fact, this week the FCC guaranteed that cable companies eat the cost for an additional 3 years. They mandated that all cable providers (coax based only) provide a viewable analog OR digital signal to all subscribers until 2012. Linkage (pdf warning) It would be easier to comply by sticking with analog signals for the mandate, but customers (and the FCC) are demanding digital broadcast.
"But wait," you say, "they can get a digital cable box and keep the older TV!" Well, sure, but then we get to hear about how the cable company is bleeding it's customers dry by charging for equipment. I call horseshit on this one. Cable companies charge an average $7.50 monthly lease fee for the box that costs them $300 upfront, plus maintenance and repair. In "only" 40 months of maintenance free operation of that box, the cable company breaks even. Yeah...that's certainly not what I would call milking the customer.
"Why can't they use a third-party box, like a TiVO?" you might ask. They certainly can but to access encrypted channels, the box will need CableCards, the abomination of technology that they are. I work in the billing department and since they are authorized through our billing software, I support and troubleshoot CableCARDs on a daily basis. They have potential, and would work SO much better if manufacturers would standardize on a set of firmware...but I'm diverging from the point. Besides, the bigger question is "WHY DOESN'T ANYONE ELSE MAKE A 3RD PARTY BOX?!" Personally, I think there is not currently a market for cable boxes. How much money did TiVO lose last quarter? Ah...only $17 million.

I second that.
