    I agree with Mike on this one. If it wasn't for government regulations on this one there wouldn't be a HD TiVo. The bottom line is that cable co's like STBs and if they had there way they'd control everything in our home.

    Time Warner Hilton Head SC has just gone to SDV and I am seriously considering recommending that my dad switch over to Directv and sell his S3, not just because of that, but because TW is horrible, only offers one broadcast network (CBS) in HD and charges extra for ESPN HD

    That's interesting. The whole TWCSC system is run out of Columbia. In Myrtle Beach we get the Columbia NBC station in HD, although the local NBC station is Wilmington. There's some wording in the CFR about using stations closest to the head end. IF TWCSC's head end is in Columbia, the entire state could end up receiving Columbia channels.

    I dug up this letter Albany TWC sent to Cable Card users in August 2006:
    I have verified the following channels are currently SDV on Albany TWC:
    001 TWC information
    746 Showtime West
    747 Showtime 2 West
    748 Showtime 3 West
    749 Showtime Extreme West
    750 Showtime Beyond West
    754 Showtime Next West
    755 Showtime Family Zone West
    756 Showtime Women West
    763 The Movie Channel West
    764 The Movie Channel 2 West

    I haven't checked the HBO, Cinemax, or Disney channels and I don't have Starz or Encore.

    That's a pretty considerate cable provider. Though they can be occasionally handy, you don't really need the other-time-zone feeds of those channels. Presenting those channels as SDV first is awfully nice of them.

    Comcast in my area dropped all the West Coast feeds. Their reasoning was that people can either watch the East Coast feeds or use OnDemand.

    assuming the tuning resolver shows up at some point. Would it also likely enable PPV and VOD? Or just SDV?

    I guess it's not likely as then cable would somehow need to get guide info to tivo for ppv and vod selections that tribune currently doesn't have? Would that be the only hangup or are their other technical issues?

    For PPV or VOD it would have to interact with the billing system to verify credit/ablity to charge for the service purchased.

    The tuning resolver / "dongle" wouldn't have to interact with the billing system; it would only have to be able to allow a request transaction to be sent back to the headend so that the proper decryption keys get sent to your cable cards to allow you to watch the show. If you are in arrears, your request would get denied and you wouldn't get the keys.

    Technically once you have 2-way communication anything is possible. I don't see why the resolver would have to interact directly with the billing system since the resolver could send info on what device it's plugged into, which presumably the cable provider knows is tied to a specific account (like how it knows your cable box is tied to your account).

    I'm assuming that they'd want the resolver to send the cableCARD pairing information since otherwise the user could tune to (though not receive) an unauthorized channel. I suppose the cable industry could just have the resolver send nothing but tuning requests and make it with no smarts at all, but that seems kind of stupid since it would send requests for channels the user isn't allowed to receive, which would be a waste of bandwidth.

    At that point all they'd need is some kind of standard PPV/VOD interface protocol that the TiVo could use to talk to the cable companies' servers and TiVo would have to code something up on their end to display to the end user. I highly doubt that will happen (knowing the industry), but there's nothing physically preventing it from working.

    Yes, lets add more complexity to the device so it would take even longer to get to market.

    Technically it could be added after the device is in the marketplace (though it will probably only be available for rent) since all the resolver does is allow upstream communication. It's up to TiVo (and other CE manufacturers) and the cable companies to decide how it is used.

    The data that runs over the resolver should be independent of the resolver itself (if it's designed correctly), the same way that you didn't need to buy a new network adapter for the TiVo when HME apps came out.

    I've thought about this and conceptually it wouldn't require much more for basic IPPV and VOD menu support.

    The original V1 CableCARD spec contained an API running in the CableCARD for fixed versions of Interactive Program Guide, Video On Demand and Impulse Pay-Per-View applications, based on HTML. The cable providers rejected it on the grounds that it was too inflexible, holding out for development of OCAP, which has taken an additional 5 years to come to fruition (a year or two of which was mostly politicking).

    Given that the resolver will be provided by the cable company, I am assuming that it will have the system-specific logic on how to talk to the SDV server, so the TiVo can talk to it over USB using a generic protocol. One of the issues with SDV is that there are several SDV protocols out there, and the question was where the system-specific logic would live (in the host device or in the "resolver"). So I suspect that the "resolver" is more than just a stripped-down cable modem.

    The Tivo would probably have an option like the Network Option (phone vs Ethernet) with selectable options concerning cable plant hardware and possibly the cable company itself. From a hardware standpoint I assume a cable box communicates upstream via its DOCSIS cable modem (just an assumption, I really don't know anything about this), so I'm not sure why a "resolver" would need more than that.
