    I truly do NOT want them introducing the dongle until it works and works reliably.

    Wow. The BigBandNetworks SDV system on SA networks is a wildly popular combo. Of course, TWC has the largest SDV deployment by far and they're primarily SA-based. In that chart, 15 TWC systems, 3 Cox, 2 Comcast, 1 Charter, 1 Cablevision and 1 Videotron.

    So far, we've heard about development of the Motorola dongle though there are only 2 Moto networks out there using SDV.

    It also says that TWC San Diego is using SDV (SA Network, SA SDV system--I, luckily so far, am on Cox). There've been some complaints about a few channels not being tunable via CableCARD lately, but people thought that they were actually there on the wire, just not included in the CC map. People have been told that there would be no new HD channels for CableCARD users by CSRs.
    When has cable ever waited until a piece of equipment worked reliably before rolling it out? :rolleyes: (at cable, not you, bicker)

    I don't think that the deployment of SDV has been very rapid at all. Comcast, the largest MSO in the nation by nearly a factor of two, has only two systems using SDV, both labelled "Technology Trial". TWC (the second largest) is being pretty aggressive, but at this rate it'll take them more than a year to cover their entire system. In the two months since the last snapshot taken by that site only 3 systems were added. Looking at that list, it could take a couple of years before we see ubiquitous use of SDV. Of course, if D*'s copious addition of HD channels is effective, the pace could quicken.

    Of course, none of this is any consolation to people in the TWC Austin and TWC Oceanic systems, where massive numbers of channels are being presented in SDV, including many that they had access to via CableCARD previously. Tuning Resolver development and deployment should proceed with all deliberate speed (before Cox San Diego can add the Sci Fi channel as SDV, which will cheese me off massively :D).

    Looks to be a fairly complete list which jives with the informal list being kept here. One clarification is even though some markets are not yet deploying SDV, they are already denying channels to CableCard users in anticipation of SDV deployment (the premise being don't give the customer some newer HD channels and then yank them away in a few months). That is the case for Cox Orange County and I believe a few other Cox markets not already on the list.

    Well, let's put it this way.... surely they should wait AT LEAST until it is reliable to their standards, if not ours. Surely, they shouldn't release it earlier than their standards would dictate! :eek:

    Eh? :)

    Cox San Diego County has announced a roll-out of 13 new HD channels to a couple of southern areas in mid-December and to most of the rest of the county in mid-January; we'll see whether they fail to add them to the CableCARD mapping. What's keeping them most busy right now is an upgrade from 750MHz to 1GHz bandwidth, so they don't really need to add those channels as SDV, since they only eat up a minor fraction of their added capacity.

    At the bottom of that announcement that say:
    It doesn't matter much to me either way. I could give a lesser damn about any of those 13 channels. There are a good five or six HD channels that I already have that I rarely watch: A&E HD, National Geophraphic HD, TBS HD, MOJO, HD Theater, etc, etc--they could take any of them away and I wouldn't notice. Bring on Sci Fi HD!

    The 750MHz->1GHz upgrades here are about half way complete in Orange County and there are already new HD channels broadcasting on RF channels > 750MHz that are only available to cities where the upgrades have been completed - they actually have a web page detailing which cities are expected to be completed when. So even though theoretically with the bandwidth upgrades SDV is not necessary to accommodate these new HD channels, looks like they have aggressive plans for SDV anyway. As I mentioned before, the entire digital simulcast channels are slated for SDV and CableCard customers will thus revert back to analog versions once deployment begins. That plus any digital channel additions from here on out will be under SDV umbrella supposedly. Perhaps they are saving the bandwidth for many more future HD channels (to keep pace with D*) as well as for much higher broadband speeds.

    Sound like even without switched video, CableCard users on Cox will be screwed because any new stuff above 870Mhz will be inaccessible.

    That and Discovery HD and I'd be happy. It's kind of sad when I go to find HD stuff to watch and there's nothing good on so I end up watching SD.

    Has Cox publicly defined what channels have been placed into the switched tier in Northern Virginia and are any of them HD? I've read they were going to use SDV to "free up space for more high-definition content," so of course it would suck if said HD content were itself switched--at least until we get the dongle.

    I'm in the same market as you and there was a lag between the first expansion in the HD channel lineup several months ago between where I'm at in Coto de Caza and some friends in Ladera Ranch. Ladera had the channels at first release, so I chalked it up to them being a new(er) community. I ended up getting those channels right about the time they expanded the HD lineup again; when I called both Cox sales and tech support about this, they couldn't even spell SDV, but they assured me that it was due to a "re-provisioning" effort going on and that I would ultimately receive those HD channels. We'll see.

    No nothing official AFAIK. 2nd tier CSRs seem to know about it - the one I talked to even knew about SDV and claimed to have an internal email about it. From what I hear in local forums CableCard customers are supposed to be getting an email sometime soon about it but I haven't got anything. Note that with my PC QAM tuner I can see which frequencies the newer channels are on but they are not mapped in my Tivo channel map so I can't tune them - I think this is intentional by Cox. No channels that I care about yet fortunately... However channels < 100 switching back to analog will be a bummer: even for those only USA & SciFi are the ones I watch.

    I don't think that they need to put television programming above 870MHz; they need quite a bit of bandwidth for telephone and telecomm.

    This article mentions some possible future plans of dedicating 870MHz-1GHz to mpeg4:
    http://www.onetrak.com/ShowArticle.aspx?ID=2870
    Article also sums up future long term plans (from now to 2010):
    # scale back the analog channel count from 74 to 68
    # increase standard definition channels from 110 to 200-plus
    # raise HD channels from just 8 in 2006 to 100-plus
    # boost data bandwidth to 25 Megabits per second downstream, 4 Mbps upstream.

    4 Mbps upstream would be nice for my Slingbox...

    I was somewhat heartened by the fact that AT&T used its uverse service to show the Dallas - Green Bay NFL network game on television. They showed it to state legislature members. However, it's still not available in my area, nor is Verizon or any other cable company.

    The S2 is still going (barely) and it's a huge relief to have MRV back, but if I need to replace the S2, I have no idea what I'd do. I honestly can't see buying a TiVo HD given the massive use of SDV in TW's Austin market. I think I'd just get the TW DVR and live with it until the SDV issue is sorted -- if ever.

    Not really, IMHO. The upstream would become the limiting factor before you came close to using that much downstream bandwidth for data.

    There are other uses that they can make of it if CableCARD devices aren't required to tune that high.

    On a related note, according to this Engadget blurb, they're also increasing standard data bandwidth up and down, continuing to trim the analog channel allocation and adding equipment to reduce the local node size from 650 to 250 customers average (apparently 250 is some kind of magic number for SDV).

    With the tuner resolver apparently dealing with the SDV issue, do you think they will pass up another opportunity to mess up cable card users?:) I realize that that there are legitimate reasons for SDV and putting new content on MP4 in the above-870MHz range, but the side-benefit of pushing people to their proprietary set-top boxes must be irresistible.

    Sure, they can deploy set top boxes with 1Ghz tuners. And the CableCard spec can be revised, but that won't help existing devices.

    It gives them room to add another tier of HD channels, when and if they need to, without having to dump analog.
