Comcast moving most analog to digital

[DJ Rob]

I'm not sure if this has been mentioned but I figured I'd pass it along...

I've been told by a Comcast tech that in most areas they serve, Comcast will be moving most of their analog stuff to digital tiers by around February 2009. The only channels left in analog will be locals and public access channels because of agreements with certain municipalities.

Sounds like the OTA situation has been mutated into meaning Comcast will be moving their analog signals to digital. I think it's doubtful that Comcast will be moving a large amount of analog channels to digital anytime in the next few years (though I wish they would do it all NOW).

It would be a great opportunity for them though to do it at the same time.

Think there are two big reasons for them to do this:

1) the more analog stations that are moved to digital directly corresponds with opening of more bandwidth for HD channels. I think the ratio is something like 1 analog station = 4 digital ones (or something like that)

2) easier gatekeeping by requiring the digital box. Their restrictions on analog cable seem to be quite laxed. With cable internet only or cable internet with limited basic - I don't think they have a way to filter out the extended channels. (ie I have limited basic with their internet service and get most of exteneded basic as well; then add in the QAM tuner and it expands even more - all the digital music stations as well as the neigborhood's OnDemand streams). Once all the extended channels are encrypted digital, it will solve that problem.

In Baltimore ION, CMT, and G4 will be digital only as of April 9, leaving us with 68 analogs. We're getting 3 HD channels that day. I imagine they will be doing this throughout the year.

Chigago got rid of 38 analogs last year.

With QAM 256: 1 analog = ~20 SD digitals or ~3-4 HD channels

It would be an easy bandwidth fix for Comcast to go almost completely digital, but I think they're worried about losing a lot of the grannies and luddites out there who think that all Comcast wants to do is charge them more by giving them a box (that's just a nice side-benefit for Comcast ;-)).

In my area there are roughly 60-something analog channels still. That's a LOT of bandwidth.

If they bit starve them (or switch to MPEG4) they can, but I haven't seen cable do that yet. Typical numbers are 7-12 SD channels and 2 HD channels. Each 256 QAM channel can handle 38.4 Mbps. Typical HDTV is 19.39Mbps

Four technologies Comcast needs to implement to really compete with Dish, DirecTV & FiOS in no particular order:

1) 1024 QAM
2) MPEG 4
3) SDV - Switched Digital Video
4) DOCSIS 3.0

I work at an electronics store. Back around Valentines day, they moved GSN and CMT from analog to digital. Our service department was inundated with "my tv isn't working right, there are two channels that won't come in" phone calls. Some of the residents of a nearby retirement village came in wanting to buy 40" Sony LCD panels so they could get GSN. Very rough trying to explain to them, "You can buy this $1699 television, but it still won't get your channel without a cable box." The newspaper ran three news stories on it, and one of the local tv stations ran a week long "explanation" of the DTV conversion during their 6 o'clock newscast.

2 would be the quickest and easiest method to boost their bandwidth. 1024QAM I don't think will happen for a while. Too many issues to resolve to make it work. It requires a much higher signal to noise ratio to pull it off than what is spec'd for cable. They'd probably have to require everything to the house to get rewired to get it to work.

Switched Digital Video is a band aid solution, but it will potentially provide some needed bandwidth.

I believe DOCSIS 3.0 is on its way.

Here in Chattanooga the Digital Sample pack is the same price as the Standard cable (64 analog channels I think), with some digital channels added, wile switching more and more analog channels to digital to encourage more people to get digital STB's. As more and more people have digital STB's it allows them to increase the number of analog channels converting to digital only.
