View Full Version : TWC won't give me HD via Cablecard

I have Oceanic TWC (OTWC) and get HD via their leased (POS) DVR S-A 8300HD.
I also watch most SDTV on 1-st gen TiVo, though having 2 DVRs is a PITA. When new TiVoHD player came out for reasonable price, I thought it would be the answer to my problem, as I didn't want to give up HD but can't stand the S-A 8300. It is absolutely awful.

Last week I ordered a new TiVo HD, which arrived Friday. Last Thursday, I stopped by TWC office to p/u Cablecards so I'd be ready to go. I was told it required a service call ($30) and the 1st available date was 3+ weeks. That bummed me out, since install is so easy...

Then, today I rec'd call from OTWC (a f/u of a call I made re getting Cablecard to install myself) to let me know that the customer service rep I spoke to last Thursday failed to inform me that they are switching to SDV bi-directional digital feed in 2 weeks and that it was incompatible with Cablecard. In other words, my new TiVo HD could receive SDTV but would be unable to access any HD channels. I had a small eruption, mostly maintained my cool and went to work with some online research.

What I discovered is that the cable industry has been pushing the SDV delivery b/c it will free up bandwidth for VOIP, ISP and even more HD channels. They also want to free up more bandwidth for PPV and interactive features which can generate more income.

I then got on the phone with TiVo tech and learned a little more:

The Cablecard problem has 2 issues, both solvable, but as yet unsolved. #1 Cablecards come in 2 flavors S (single channel) and M (multifeed). The S cards are unidirectional and will simply not work with SDV (which is why they wouldn't support PPV and interactive features, as well, which require two-way communication). Easy sol'n is get an M card. In fact, they are no longer making S cards, I was told. Problem is, CTV operators want to use up their inventory of S cards. There was talk of a hardware sol'n using a "tuning resolver" outboard device that could give an S card two-way (needed for SDV) functionality. But it evidently has not materialized. If you can get an M card, though, it's a moot point.

Assuming you could get an M card, there is still a problem. The frequency decoding algorithms are proprietary to the CTV companies. THE REAL ISSUE HERE, according to the TiVo tech, is that CTV companies don't want to give up the income stream for "leasing" you a set-top box (STB) or DVR. Cablecards obviate the need for a STB. So, the cable companies will not give the information to properly decode their signal to the card manufacturers or TiVo. According to the same TiVo tech, the whole problem could be resolved with an M card and a firmware upgrade that allowed the TiVo to receive/decode the HD signals. Basically, TiVo's stance is "we're waiting on them and they don't want to give up control of interactive revenue stream and box-lease fees.

On the other hand, I was told by engineer for OTWC that it's "TiVo's fault" because they just don't want to make the firmware changes. Of course, that explanation makes no sense whatsoever to me, as it would only hurt TiVo. He also shyed away from the "only S card availability" issue, as they can charge twice as much per month for 2 S cards vs. 1 M card (I was quoted $6/mo/Cablecard lease fee- in other words $120/yr to "lease" 2 PCMCIA cards).

What's really going on here??? How many other people have HDTVs that require Cablecards? Are other people, unaware of this problem, just going to "lose" their HD channels when their cable companies make the switch to SDV? I scoured the OTWC website and it said nothing about the SDV change. In an FAQ section on Cablecards, in the same paragraph, one sentence read (exact quote) "Please note that most HD channels are not accessible with a CableCARD. Please note that while most channels are available with a CableCARD, some are not accessible." Each link re this issue was directed to the PPV/interactive issues with S cards. No mention was made of the SDV/M-card issue.

One other issue is that the TiVo player keeps everything in digital (which is a good thing) and that STBs output only analog via composite, S-video or RF and digital over component or HDMI. Is it possible that TiVo was just not willing/able to include an HDMI or component input on their DVRs? Would that have solved the problem (though still required a STB?) Actually, it would NOT. The problem, here, is that with te SDV system, the DVR (be it TiVo, S-A, Motorola, whatever) has to be able to "tell" the cable company to "send" it a specific feed, much like entering an HTTP address in a web browser and hit "enter" to send your request to your ISP's server. With SDV, only the requested streams are delivered, as opposed to present UDCP system in which ALL feeds are sent to all subscribers, filling up the broadband "pipe" with a lot of unnecessary traffic. The SDV system is bi-directional, so it's not just that the DVR has to have the right connections for passive reception, but that the DVR/STB has to be able to "communicate" with the cable provider, which means they must speak the same proprietary language!!!!

All I can say is that, fortunately, I bought the TiVo 1 week ago and they have a 30-day no questions return policy. I'm just stuck with tthe $35 shipping it back to them and all the time/frustration this adventure has taken. And, that I'll still have to put up with this POS S-A DVR if I want to continue to watch HDTV. It's not even a problem that could be solved with more money. There is no sol'n for HDTV and a device that requires a Cablecard.

Dr. Norm, it sounds like you're doing your homework; kudos to you for that.

Allow me to disspell a long standing myth about CableCards -

Every single CableCard ever manufactured is capable of operating in two-way mode. What makes a device one-way or two-way isn't the card - it's the host device. In order to operate in two-way mode, the host device must have a return path RF transmitter inside in order to send your remote control button presses back to the cable company's headend.

When you plug a CableCard into a host device, the card queries the host for the presence of a return path transmitter. If the host doesn't have one, the card kicks into one-way mode. This has been true since day one, and is described in a CableCard tutorial from CableLabs (http://www.opencable.com/primer/cablecard_primer.html), the inventor of the Cablecard standards.

Having said that, this doesn't speak to the issue of Switched Digital Video. The industry is looking at developing an external sidecar device which will have two-way SDV capability facing the network and a unidirectional connection to the CE device. This will enable legacy devices to play in the SDV sandbox.

ck-
thank you for that excellent tutorial. I had already added another paragraph about that issue while you were replying!

As you stated (much better than I did): the issue is not so much the CableCARD, but that the TiVo has no ability to "talk back" to the cable company to communicate its requests.

I was unaware of the hardware difference btwn S and M cards. If I understand correctly, the S card was single channel, but had the ability to be bi-directional (two different issues). The M card can both stream (M)ultiple data feeds AND it is delivered as a bi-directional card, which is also what is required for SDV.

Great info, but still leaves me sitting in my own ****. I figure I'll just have to return the TiVoHD and perhaps by the time this issue is resolved, I can then buy the same model at 1/2 the price.

Also- I bought this thing "brand new" 1 week ago and it has only been available for a few weeks. It's kinda hard to think of it as a "legacy device"! I know things change fast in this industry, but a 3 week lifecycle is really pushing it. Sucks...

aloha,
norm

this is a partial copy of an email that was just received from a very senior OTWC Field Tech regarding the issue of receiving HD channels via CableCARD:

Okay, found out that the problem is NOT with OTWC but with TiVo. Evidently they need to write code to accept our Cable cards for HD offerring.

Once that happens, we will be able to offer our HD product to TiVo Series 3 users.

Does that sound correct to you?????
TiVo tech said it was OTWC that wouldn't provide those codes to incorporate into TiVo device. He also said that if they DID have that info, they could perform a firmware upgrade with it, though, you would still need external sidecar device to interface for cablecard .

TWC in Hawaii is moving all HD channels to SDV on Sept 24. I think the confusion may be coming from this. So after this date, no current cablecard devices would be able to tune HD channels.

yes. I understand that. now what??? I have a brand new series 3 paperweight.


It would have been nice if they had "disclosed" this info their customers.
I had to do some intensive searching today to learn this- a few hours of my time. thank god for AVS (and you all out there)

I know this is new and a major change, BUT even their website is extremely vague and misleading and that's not very fair for us customers that get stuck by it.

I would return the TiVo HD until there is a fix for SDV. The current rumor is there is a usb dongle in the works. However, I wouldn't count on that happening anytime soon. In the meantime, there is nothing TWC or TiVo can do for you to get HD channels over cable through cablecard. Also, I would definitely write the FCC and your local franchise authority about TWC basically making CableCards obsolete.
