    Anyone else bothered by this footnote on p.34 of the FCC pdf document referenced in mega's post:
    http://fjallfoss.fcc.gov/prod/ecfs/retrieve.cgi?native_or_pdf=pdf&id_document=6519612942
    That sure seems to complicate things for Tivo since they have to be sure that if there is a recording on a switched channel that it won't be negotiated away during the recording. Not sure what the timeout period is but it better at least be longer that the 30 minute Tivo buffer.

    I dunno, how about the incentive retaining customers with such "legacy" hardware who would switch to FiOS because they don't need to use SDV? Given the high-pressure marketing push companies like CableVision are making for their VOIP phone service, it seems clear to me that they're pretty scared of FiOS.

    It's not very different for the UI than the current screen that pops up to tell you when it needs to change the channel for a scheduled recording. I don't actually know what happens to the 30-minute buffer in that case, but I vaguely remember the buffer being kept as long as you don't hit the 'live' button or go to another program.

    If this thing works, I say bring it (and SDV) on, along with a few more HD channels!

    Also both Comcast and Cox have a relationship with Tivo to provide Tivo software on their DVRs so if nothing else you would think those 2 cable providers would have some obligation to work with Tivo on this issue.

    I don't think it is terribly complicated to implement given there is already an event queue that can interrupt LiveTV, but depending on the timeout it could get annoying for end-users that watch the same channel for long periods in the background like news and CNBC junkies, assuming of course those channels are moved to SDV. If it is too short, it'll be like the dialup Internet connection timeout people used to hate about dialup Internet, before always-on broadband became popular.

    Supposedly the SDV timeout on Time Warner boxes is currently up around 4 hours, and any activity (ie volume up/down, whatever on the IR) is enough to tell the box you're still watching. If this is an acceptable implementation, any TV that has somebody actually watching it should be fine. I wouldn't recommend this for a sports bar, but every one I've been to lately is on satellite anyway.

    ...I would think you'd want it for longer than 4 hours (a movie like LotR or Gladiator could run that on cable with commercials), but I'd think the odds of you running into this problem too often are pretty slim. If it became a big issue, couldn't TiVo just add a "Always say yes on this channel" option? The "Always say yes" choice would have to be narrow (by channel or time slot) to not nullify the raison d’être for SDV, though...

    My big issue with this solution is that cable makes it seem like this is a surprise: once we were told that SDV wouldn't work with cablecard + TiVo, we jumped to action. Action should have been taken, tested and rolled out before SDV was ever put into place.

    For the purposes of Tivo, "recording"=watching. When a recording is complete, it will go into "not-watched" mode, unless the user is actually watching the LiveTV buffer.

    Yeah, I can't imagine sitting and watching a 4 hour movie without recording it or pausing it at least once. I guess the worst-case scenario is a house guest so unfamiliar with technology and uncomfortable with your TV that they're scared to push a button so they can keep watching something.

    I am thinking it would be an accessory you get along with your cablecards.

    Unlikely. It has no authentication in it, so you'd still need cablecards from the cableco, but the widget would be sold by TiVo or a 3rd party. It's just a cable transmitter, perhaps with a built in splitter that goes between the widget and the cable-in RF connector on your TiVo. The fun of this is that if you have a marginal signal now, expect it to be at least 2dB more marginal after installing it. It might even have trouble operating through some cable amps or splitters you might have. Still, it beats having a separate cableco box just to watch one or two SDV channels I care about.

    Let's face it, if it wasn't for satellite, there would be no HD cable channels and probably not even digital cable channels. The only thing that motivates cable companies to enhance anything is competition. The only reason SDV even exists is because DirecTV has been launching tons of new HD channels. If it weren't for this and FiOS breathing down their necks cable would still be stuck in the 1980's technology wise.

    It's completely ridiculous that cable can't offer PPV, On Demand and SDV via a software solution. If I can securely order movies from my Amazon account I should be able to do the same (ie. order PPV) from my cable company. It should be easy enough to link a TiVo with a cable provider for PPV, SDV and anything else that requires 2-way communication. Specifically, this solution would only be available to broadband users (as is Amazon Unbox, etc) but it has no limitation on broadband service provider since TCP/IP is provider independent.

    I laugh everytime I see one of those Cable Labs commercials about how they are so innovative. They just makes me want FiOS even more.

    The funny thing about this whole thread is that the solution is already there ... the dongle (USB or E-NET) IS a CABLEMODEM that is already avaliable.

    Just a splitter on the cable end, a registerd CABLEMODEM, either USB or E-NET and viola. They can verify that the request comes from THAT registered CABLEMODEM if the concern is w/ security.

    This way every system is common (since DOCSIS from CableLabs sets CABLEMODEM standards) and all needed is the s/w on the TiVo/CE device to send the channel request and corresponding piece on the HEADEND.

    Problem solved ... why can't it be this easy????

    Not to nit-pick but the channel request is processed at the hub level, not headend.

    I think it is actually propogated up to the headend and processed in the headend then switched at the hub. They will not be putting SDV management servers in each hub.

    The system that I am pretty familiar with is done at the HUB level.

    MegaZone has posted about this.

    He found the FCC filing. Relevant language:
    Makes it sound like this is well under way already.

    Informal poll: # of months before we see this device in the wild?

    I'm going in for 20. I'm a glass-half-full kind of guy.
