    Let me correct myself... you will never be able to tune them without the Tuning Resolver which may or may not ever appear.

    Even if there were a way to do this, you could not ensure that all of the channels that you use would always be available. One possibility in an SDV system is that all of the bandwidth allocated to the switched set is in use and you're out of luck; the use of switched tuning is predicated on this being unlikely to happen if they choose the channels in the set carefully. So, even with authorized equipment it's possible that you ask for a channel and it responds, "Sorry; I can't give you that channel now, try again later.".

    It doesn't "screw CableCard devices" at all. All SDV units employ CableCards. SDV is a 2-way service, and as such requires a 2-way host. It's that simple.

    The decryption key and channel map has to be passed to the unit requesting the stream, whether the stream happens to already be there or not. It's very little different than a premium non-SDV channel. The fact HBO is present on your CATV drop doesn't mean you can get HBO until your CATV provider gives your CableCard the information it needs to receive HBO. The only differences are, with SDV, the channel in question may appear on any carrier in the system, and your receiver must request the information from the headend as well as requesting that the headend send out the program. With a non-SDV encrypted channel, the program will always be found on the same carrier, and the information concerning the decryption is sent out once and stored permanently on the CableCard subsystem.

    S2 TiVos don't support CableCards. Neither the S2 nor the S3 / TiVo HD are two way. The fact the STB will make sure the stream is there is irrelevant. Unless the headend sends the channel map and the encryption key specifically for the CableCard that will be receiving the program to that CableCard, the CableCard will never know what to decrypt, how to decrypt it, or to which frequency to tell the host to tune.

    The whole point of SDV is to allow any any content to be served up on any carrier at any time. The odds a particular "channel" wil wind up on a given carrier or even stay there is small. Since the CableCard won't have the encryption key, the point is moot, however.

    Excuse me for not using the correct semantics: "does it screw unidirectional CableCard devices". But since we're being picky, I presume you meant "all current SDV units employ CableCards", because my >6-year-old old SA Explorer sure as hell doesn't have one, and it handles SDV just fine. :p

    I understand that. My question was whether the current lineup was pushed to a (one-way) card-enabled device when first provisioned, and it was able to cache that information locally, and thus be able to receive the same channel again at a later date if it happened to still be on the same carrier, rather than explicitly requesting it every time.

    Unless, as I was pondering, the channel was forced to "stay put". But of course if the information is never sent except in response to a request, then the caching aspect is indeed moot.

    ...unless the channel is being requested again every few minutes, and is thus never released back into the pool of channels eligible to be switched. By constantly requesting a channel, you could effectively lock it to a given carrier, in much the same way that constantly renewing a DHCP lease can result in an effectively-static IP address.

    I know exactly what you mean, and while that might get you SDV channels on some other QAM tuning device, it won't get you SDV channels on a TiVo since the TiVo relies on the cablecard channel map to decide what channels to tune, and that channel map has all SDV channels removed.

    As for the people beating you up over your choice of words, just ignore them...they have nothing new to argue over so they like to pounce on people that don't want to follow every nuance of this giant, nearly-worthless thread.

    First of all, I didn't beat him up, and secondly it wasn't his choice of words that is at issue. It is the fundammental problem which is at issue. The problem is not SDV, and SDV doesn't screw up anything, per se. The problem is that the FCC pointedly and deliberately excluded unidirectional devices from being able to handle 2-way services in it's specifications for all UDCP devices and then failed to provide a specification for bidirectional hosts. Then the proposed contemporary standard which does provide specifications for bidirectional hosts is produced with totally unacceptable reservation in it and is left unratified. This leavs the door wide open to what exactly has happened: the existence of more than one incompatible SDV format and a near inability to produce a reasonably priced universal consumer receiver which can take advantage of 2-way interactive sevice like SDV.

    Brighthouse in Birmingham, AL has implemented SDV. Just affecting two channels now but over time it will be all of them.

    Boo.

    That's unlikely, if their engineering department is any good. SDV only pays off if you choose the channels well--"switching" highly popular channels that will virtually be viewed by someone in every network segment 24/7/365 doesn't help.

    I don't know enough about it, but that's what the technical manager (who seemed to know his stuff as much as you can gather in a 3 minute conversation) told me. His words were approximately "eventually we'd like to go all SDV. That's the goal."

    He probably does, although "eventually" is a really big word. There are cost and management efficiencies involved in having a single platform for deployment. Add to that the fact that volume drives economies of scale, and at some point is not unlikely the cost to the MSO for delivering an SDV QAM is no higher than delivering a static QAM. At that point, it doesn't matter whether SDV is more efficient for all channels, or not.

    I also suspect the market share of every individual channel will continue to shrink until eventually there are very few, if any, channels whose market share will guarantee them a slot in any given node at any given time. Beyond that point, every channel will benefit from SDV. Somewhere below a 1% market share, a channel will no longer delivered to the majority of nodes in the system at any given time.

    Frankly,I hope that day comes very, very soon.

    Now it's official. Add Cox, Orange County, CA to the list of providers deploying SDV. The deployment goes live April 8 2008. See:

    In addition to the above, there are already 9 HD channels as well that cannot be viewed with UDCPs:
    CNNHD, DISCOVERY HD, GOLF/VS HD, NFLHD, TLCHD, FOODHD, HGTVHD, HISTORYHD, APLHD

    I know this was an old post, but I just now spotted it. This is false. The equipment which handles the switching is quite large - typically it occupies several 7' relay racks. The node is the size of a bread-box, and either hangs off a telephone pole or else sits in side a pedestal. Most CATV companies use a pedestal which is smaller than a doghouse to house a node, unless they collocate the power supply with the node. The node does nothing at all other than convert the signal from optical to RF.

    Just FYI Here's San Antonio's current lineup. 'Lots and lots of SDV, but only a few in which I'm really interested. Still, there are half a dozen or so HD SDV channels I'd like to get (Discover HD, A&E HD, Animal Planet, National Geographic, etc.)

    Has anyone heard of a class action to settle or at least speed up the resolution to these issues? It seems that both TiVo and cable providers, among others are to blame for selling devices that can not work together.
    Thoughts?

    I think you should consult a lawyer and let us know how it goes. People may be interested in joining if you provide some details.

    Considering it's expected in the second quarter of this year, do you honestly believe between lawyers, courts, appeals and foot dragging that anything could ever be accomplished in an adversarial manner in 3 months or less?

    I haven't heard of cable companies selling devices only renting cable cards.
