    Check the Detroit forum of AVS. They've started analog reclamation there.

    I'm a Comcast subscriber in the Seattle area, currently receiving analog cable via a series 2 single tuner. As I understand DTA's will be required for people like me. Does anyone know how this will affect my Series 2 functionality? Thanks.

    Here is a link to a recent article in the Seattle Times about the pending DTA rollout.

    You'll need to use an IR blaster and the DT will become a ST.

    Also Comcast isn't going to use encryption on the DTA's yet so you could use a clearqam capable device. That doesn't stop them from trying to get a waiver to enable the privacy mode.

    Why would they want to deploy an all digital box that's not capable of 2-way services? (ppv, on demand,...) Aren't they cutting themselves out of possible revenue streams? This thing can't even tune switched digital channels, right? (not 2-way)

    The DCT700 is pretty damn cheap to produce in itself. Is this new box that much cheaper to produce? Pace has a reputation for ultra low end stb's, but are they THAT cheap?
    :confused:

    Then again, I may just be missing something.....

    Numbers that I've seen are that the DCT700 costs $50 - $60 and the Pace box is less than $50. Ten dollar savings on 12 million boxes equals $120 million.

    I though it was Digital To Analog (DTA).

    On the 6:30p news last night KING announced that Comcast channels above 29 (Limited Basic) will go digital in April. As the Times article states, Comcast will supply two DTA's for free and additional DTA's on the same account will cost $1.99 mo. each.

    If a demodulator is used to convert DTA's Ch.3 to composite an S2DT could continue to record two programs at the same time.

    The DTAs are SD clear-QAM tuners using an RF connection. They are similar to the integrated clear-QAM HD/SD tuners in TVs (w/o the HD), in that they only provide clear Digital channels with station IDs; no interactive features. Therefore, those that have clear-QAM TVs won't need these boxes for SD Expd.

    They will be using the filtering system for blocking non-Expd. customers from getting Expd. It has been speculated that they will using the same frequencies, so as not to have to re-install filters. There will be extra bandwith in those frequencies, but, so far there have been no reports of HD Expd. channels being in the clear.

    So, having a clear-QAM TV only helps if your TV size to viewing distance ratio is such that PQ is unimportant, and SD will suffice. HD will need a box or CC. I am waiting for tru2way to become common.

    I have heard that DCT700 were $70, and the DTAs were $35. However, other quotes may be more accurate. Based on what I had read, I had speculated that the rental fee instead of ~$4, would be ~$2, and that is what it turned out to be.

    The problem is the DCT700 has integrated security, something basically prohibited by the FCC which requires separable security. The DTA box in question has no security at all.

    The DTA can support security if you enable the privacy mode.

    I am guessing that the DCT700 must use its security in order to function, while the DTAs don't have to use it. Also, the DTA uses a lesser security protocal, but it still would require an FCC waiver to be able to use.

    I don't Tivo so my question may be moot, except this is one of the only places I've seen any discussion on the Comcast DTA's. I have the expanded basic service with Comcast. Apparently we can get two DTA's free and then they'll charge a rental fee for anything after that. We have more than two tv's in our home and I don't like the idea of extra rental fees. Does anyone know if buying the likes of the Motorola DCT700 will work for our extra tv's that we won't have Comcast DTA's for?

    Thanks.

    Comcast is currently providing digital simulcasts of Extended Basic channels (analog channels above Ch. 29) unencrypted. If their pitch on digital conversion is to be believed they'll continue to do so:

    http://seattletimes.nwsource.com/html/brierdudley/2008480563_brier08.html
    "What we're trying to do here really amounts to a free upgrade," Comcast's regional spokesman, Steve Kipp, said.

    HDTiVo cannot map these digital standard-def channels manually so must be used with a CableCARD. If HDTiVo is a Comcast sub's only digital outlet, fine; even an S3 user would have to pay only $1.79 extra for a second CC. However, when a Comcast sub employs a standard-def digital STB in addition to HDTiVo, Comcast's $5.20 'Additional Outlet Fee' applies.

    Therefore the cheapest alternative, when a TiVo customer already has one, is to use a Lifetimed S2 and Comcast's free DTA along with HDTiVo. Using an S2DT with a demodulator (like an old VCR) will enable recording two programs at the same time and allow S2DT's tuner to access analog channels 2 through 28 directly.

    If a user doesn't have a Lifetimed S2, an option which costs more but offers Comcast's Limited Basic OTA channels in hi-def as well as digital Extended Basic channels with no 'Additional Outlet Fee' is to get Sony's HDR-HDD250 DVR, available from eBay and other sources for around $400. Sony's discontinued but impressive DVR has 250GB of storage and the ability to manually map unencrypted digital channels without a CC (although it can use a CC as well.)

    If your provider sells the DTA box, or a DCT 700, sure you can buy one. You cannot buy one from eBay or any other unauthorized outside source and expect it to work, or your provider to authorize it (required to make it work).

    That FAQ about expanded basic channels being encrypted directly contradicts what the Comcast Chief Ops Officer said for the Portland migration. They're providing the channels in the clear, at least initially. If they're planning on implementing security in the DTAs, they will need a waiver from the FCC that they do not currently have, because these are new devices which would fall under the FCC's separable security mandate (i.e., Cablecard). I smell a court fight if they don't leave it off.
