    "Digital Video Recorder supplier TiVo said it will introduce next year an external adapter that will enable TiVo digital video recorders that use CableCARDs to access switched digital cable channels without a set top box."

    --

    "Cable operators will make the new adapters available for TiVo customers in the second quarter of 2008, TiVo said. "

    No doubt it is big news. I'm not holding my breath yet though. When was the last time one of its members actually met a scheduled time frame without asking for an extension? I'll look for it to actually be available very late 2008 for an additional monthly fee.

    Great news indeed!
    I foresee many calls to my local cable company and clueless CSRs asking about availability.
    The other problem I foresee is that currently my cable company already intentionally leaves channels slated for SDV deployment out of the channel map for cablecard customers, so they will have to come up with an alternate channel map for cablecard customers with the tuning resolver, or make it the same map as the digital set top boxes if possible.

    However, these issues probably can be overcome and I'm really pleased to see Tivo & NCTA being so pro-active on this issue.

    There is elegance to such a design on the engineering side but business-wise it sucks. Any proprietary protocols should be encapsulated in the dongle--just as they are in the CableCARDs--allowing TiVo and any other interested OEMs with unidirectional CableCARD devices with USB connections and field-upgradeable firmware to implement their part of this without obtaining and maintaining licensing from Motorola, S-A and/or BigBand Networks and C-COR, which the cable providers already have to do for SDV as implemented in their headends and leased STBs. Placing the protocols in the dongles also minimizes the impact on memory in the UDCP devices which would use them, making more of them eligible.

    There are pluses and minuses on both sides but to my mind it comes down heavily in favor of the encapsulate-the-protocols-in-cable-provider-distributed-device solution, which is where they appear to be going. Even the opportunity to charge additional monthly fees for the lease of these things provides incentive to the cable industry to comply; they have the least to gain, since they only stand to lose some fraction of a very small TiVo-owner market, which won't get any bigger without some solution to this SDV thing.

    Hopefully that's because they won't (nor SHOULDN'T) charge any extra for this!

    He did add a little to the discussion for me, since the previous PRs that I read were from TiVo and the NCTA, who'd already announced that they were working on this and that we should expect a solution from them. This CableLabs announcement makes it seem like they're going to be issuing the spec, which is interesting in and of itself.

    Expect pricing to be local.

    Hopefully there won't need to be 1 dongle per CableCard??

    So I'm guessing this dongle is going to just be for SDV? Is there any reason this couldn't also be built to use it for pay per view or OnDemand type of channels?

    Sometimes I wonder just how ludicrous ideas like this ever even get started.

    Why is it so ludicrous? The functionality is very closely tied to the cablecards for authentication purposes and right now S3s require a separate card for each tuner for authentication reasons (whether they are M-cards or S-cards). Without knowing the details of the "tuning resolver" I don't see how you can rule out the possibility of needing 1 per card.

    part of me thinks the dongle only needs to tell upstream what channel is needed and get back a channel to tune to for it and they could certainly do that for both tuners with a single dongle. but then doesn't the dongle also need to keep the channel open so it appears in use and that might require more work to do both in the same dongle. if i'm the cable company having to design and build these things to keep a hand full of people happy and they want it quick then why bother building support for more than a single tuner in it? the more of them I lease the more monthly cash I take in.

    Obviously not many engineering minds involved here.

    Not necessarily... they could design it like DHCP leases. The dongle transmits that it wants a certain channel for a certain period of time. The magic server then approves the request and returns the assigned frequency and tells the dongle how long the frequency would be valid for. At some point during this lease, the dongle could send another request to continue accessing that channel on that frequency to maintain access to a switched channel.
