    I've been reading about the Tuning Adapter coming out, looking at the pictures from the cable show in New Orleans. Here's some questions to research or add to the FAQ once answered:

    1. How much will the tuning adapter cost? My cable provider (TWC) already charges me $1.75 per month per cable card. I read that Cox will be providing the box for free to customers, does anyone think this will be true for other cable providers?

    2. Will a truck roll be required in order to deploy the tuning adapter? I had to pay TWC around $22 for them to install the cable cards, don't want to have to pay another $22

    3. How much power will SDV tuning adapters draw? From the pictures, it looks like they will be powered by a AC/DC converter brick. Nice. One of the things that made a Series 3 Tivo appealing was not having decoder boxes all over the place. I live in a rural area where power is not cheap. Maybe the fabled Series 4 box will have the SDV tuning adapter built in (of course, then there's a charge to upgrade, swap lifetime, etc)

    1. It isn't clear. Most folks expect that in many cases it will either be included in some other fee or cost no more than a few extra dollars per month.

    2. It isn't clear. Some places will; some places won't; and there likely won't be any pattern to it.

    3. Good question. Unless someone has the tech specs available, I'd use the tech specs for the small STBs.

    The Series 4 might be tru2way, so SDV will be accomplished another (the more cable box-standard) way, I suspect.

    That's an overstatement. Actually, there are only about 6 or 8 SDV HD scheduled channels here in San Antonio in which I am significantly interested. All the main premium HD channels (HBO, Starz, Showtime, Movie Channel, Cinemax, etc) are on linear QAMs. So are all the local HD channels, as well as Discovery HD Theater, UHD, HDNET, HDNET Movies, MOJO HD and TNT HD. Certainly I would like to get the Discovery, A&E, Animal Planet, TBS, etc. HD offerings which are currently SDV. I'm not really interested in very much inthe way of SD video, although there are perhaps one or two SD channels on SDV which I would like to get, and no doubt there are some HD channels coming in which I would be interested, but your statement is quite an exaggeration in my estimation. A great deal of the "good stuff" is on linear QAMs here in San Antonio.

    It will no doubt vary from municipality to municipality, just as CableCard charges do now.

    I imagine some might. I suspect most won't.

    Policies of this sort do not fall under any mandate or federal regulation. Some municipalities may have some sort of regulation covering this sort of thing, but most don't. Some MSOs may implement nationwide policies for some of these situations, but most leave it up to the senior management team of the local franchise. If you raise enough of a stink with the CSR, they (or a supervisor) may be willing to waive any such fees, company policy notwithstanding. TWC locally not only waived fees in two cases at my insistence, they even refunded me several days' service in one case because of the installation troubles (including missed appointments and not having the correct equipment).

    It should be very small. I would be surprised if it's much more than 5 watts for either the SA or Motorola.

    I don't think the SA will. It's a bigger box, and I would expect it to have a transformer and primary supply inside.

    I tried to read previous posts to find this out but all I got was a headache.

    Will the SDV adapter make VOD work with the Tivo HD?

    My CATV currently does not use SDV for broadcast channels.

    That's not its intent or its first purpose, though it would technically be possible if the cable companies were to come up with a standard protocol for interrogating available programs and TiVo would support it. But don't expect it to happen, at least not when they first become available.

    No. While the adapter would provide the 2 way communications portion necessary for this to work there also has to be the VOD software interface - which is different for different headends. There have been some rumblings that Tivo is working on a new Tru2way box that would be capable of using the cable company VOD interface:

    Not a 100% Tivo related, but 100% SDV related:

    I posted this originally over at the Cablevision Optimum Online forum at dsl reports:

    That won't work in Austin. All SDV channels are encrypted.

    Seriously. I can intercept other people's porn in my head end.

    The best is, you see them fast forwarding and rewinding over the "boring" parts. LOL

    That stinks for you guys that the SDV broadcast is encrypted. I at least can watch LIVE, about 1/3 of the channels I lost at any given point.

    On a slightly more serious note, were they not encrypted at some point when SDV first was introduced? Back in '04-'05 or so when SDV was first introduced in Austin we started being able to receive the West coast Cinemax and some of the other less popular premium tiers (IFC, Encore Western, etc.) and the installer told me it was because someone in our node was watching them because the lease was for 12 hours or something. He didn't seem to be correct though becuase they never seemed to expire; we watched them for a year or two. Occasionally channels would disappear and I assumed it was just because someone altered their cable package. Then 18 months ago or so they all went away. I wasn't sure if TW just made it so the SA wouldn't attempt to tune channels you didn't subscribe to or if they encrypted them all.

    I wasn't aware there were any unencrypted digital cable channels (beyond the locals as offered or required by regulation). Isn't that the purpose of the CableCARD in the first place, to decrypt digital cable signals?

    No, I just mean someone in my neighborhood (I don't OWN the neighborhood of course) who's watching on-demand porn, I can intercept with the QAM tuner in my HDTV. And I can see all the ff, rew, and pausing they do.

    And in reply to the other poster: It appears that on demand and SDV in my neighborhood aren't encrypted. And typically its not worth it for others to "listen in" as it were with a QAM tuner, as the broadcast might stop, or the person doing the requesting might hit FF, etc.

    Most of the stuff that's been presented as Switched Broadcast by cable providers are things that are encrypted when they're linear channels and remain encrypted when transitioned to SBV. I'm particularly shocked that VOD porn on your system is in the clear--that'll end when somebody catches their little kid watching it. Almost certainly the fact that all switched video on your system is unencrypted is a mistake on the part of the people running it, which could be corrected at any time.

    That depends on the CATV system and perhaps the channel. The CATV provider can choose to encrypt any channels (excluding local channels) it wants. Some do not.

    Actually, that's backwards. On-demand is more sophisticated than SDV, because it employs what some people term a "trick play" mechanism which tells the server farm to start and stop (or fast forward or rewind...) playing a source rather than just enabling the stream for an additional destination. Depending on the channel, it also may employ a billing element. IF you will look back a few pages, you will see an extensive discussion on the nature of VOD and similar services. If a CATV company is deploying SDV, then their on-demand services will use the SDV platform as a carrier.

    Uh-uh. Nyet. Nein. Not even. The entire point of SDV is that the stream is *NOT* sent to every home served by a headend. The stream will only be sent to the node of the user who requests the content. Most CATV providers engineer their plant to serve between 400 and 1000 subscribers per node, and perhaps 40,000 - 50,000 subs per headend. Here in San Antonio, for example, there are some 500 or more nodes in 8 or 10 (I lost count) headends, so only 1 household out of every 500 would have the content available here, and since most chanels are encrypted, so is most on-demand content.

    No, it won't, as the existing stream has priority. If the sub who requested the content changes channels, however, then the content will evaporate.

    I'm really rather surprised that any systems wouldn't encrypt their SDV channels, or at least most of them. Certainly I can't imagine any CATV operator deliberately not encrypting pay channels, or most definitely porn channels. The former is asking for theft and the latter for trouble.
