    So you're saying those stations will transmit across my analog cable with no cable card/cable tuner? I guess the analog cable must have a way of carrying digital informaton on it, since I take it that an HD signal is digital in nature. By the way, I have extended basic as my lineup.

    QAM is Quadrature Amplitude Modulation. It is a modulation method used over RF (Analog) to represent digital information. Think of it as a method of modulating a sine wave both in amplitude and in phase. So the sine wave (analog) is modulated to represent all the "0's" and "1's" (digital).

    All the CableCARD does is decrypt encrypted QAM channels.

    So if you have a new TV or device like the TiVo with QAM tuners, you will be able to receive unencrypted QAM channels without a CableCARD. The best example of these unencrypted QAM channels are usually the local HD channels which are required by the FCC to be transmitted across the Cable Plant "in the clear", or "without encryption".

    That's why he was saying you should be able to receive local HDs...

    This is interesting. I take it then, that this modulated signal is superimposed on top of a normal analog signal, so that the same cable could be fed through a SD tuner or through a QAM tuner, and either way, the signal will still convert to a picture. So effectively both the analog SD and the digital HD signals are there coexisting together in the cable at the same time? (In other words, I don't have to call Time Warner and ask them to change the transmission they're giving me to a QAM signal - they're already doing that, I take it.)

    Ok...quick lesson...

    The Cable Company has control over the RF spectrum on their plant. Most Cable Plants today go to 800MHz (some to 1GHz). So from 0 to 800MHz is the whole range of frequencies available on the plant.

    Each "Channel" is segmented into a "slot" which is 6MHz wide. The reason it's 6MHz wide is because this is traditionally how wide Analog Channels are (or need) in North America. This 6MHz wide slot carries both Video and Audio Analog information for us to see, and these 6MHz wide slots are what we tune to as "Channels" on our old "Cable-Ready" Televisions.

    For example, if my "Slot" or "Channel" is at "650MHz", that would be the center of the 6MHz wide slot. So that Channel would actually be from 647MHz to 653MHz (6MHz wide...also known as Channel Width). This would then be assigned a number to represent the "Channel"...say CH125 or something...(I forget and can't remember the exact EIA channel representations...I have a book where I can reference them when needed...)

    Anyway, so that is how you get Analog channels. For Digitial Channels, each "QAM" takes up the same 6MHz slot (just like the Analogs), but instead of transmitting Analog it is a QAM signal. Also, we can have multiple "feeds" per QAM, so it is more space efficient for the Cable Plant Spectrum. The Cable Company can fit many more "channels" into a single 6MHz slot, AND usually at far BETTER quality than a single 6MHz wide Analog "channel". (well..."Better" depending on how many and what compression ratio...)

    So no, you don' have to call anyone as both Analog and QAM channels exist in their own separate 6MHz Wide slots across the Cable Plant spectrum from 0 to 800MHz (or 1GHz). Even the High Speed Data Cable modem uses it's own 6MHz slot too for the Downstream).

    (The actual downstream range is from 42MHz to 800MHz (or 1GHz) in North America.) (Upstream (for Set-top box returns or Cable Modems) is 5-42MHz)

    Hope this helps!

    Hey guys I figured I'd give my TWC Queens Cablecard install experience and provide background info.


    I heard about the bogus $2.50 digital duplication fee on top of the cablecard fee so I opted to have only one card installed and avoid paying an additional $19 fee for having a second card installed. However, when I checked my old bills I saw that for additional cableboxes, TWC charges $2.50 for DTV service as well which is included in the $10.15 fee for each additional box. So TW really should just update their website to show $4.25 as the fee for a cablecard but considering how little service reps know about CCs in general I doubt this will happen anytime soon.

    Anyway on to the install for my Tivo HD (10/13)

    The guy came by the house at 1:50 pm during the 10-2pm time frame. He only had two cards on him but lo and behold they are both Mcards dated 4/23/07. Sure enough he puts a card in sure enough the Tivo recognizes it as an Mcard after 10 seconds. He calls his supervisor and they talk on the phone about how much trouble these installs tend to give especially since this is a Tivo. Meanwhile I'm crossing my fingers to see if either card will work. The installer asked me why I did not want two cards installed and I tried to explain about Mcards but it seemed to confusing to him (and I don't blame him since I heard Mcards don't work with S3) so I just dropped the issue. Twenty minutes later the install worked flawlessly and I am currently enjoying dual tuners on my Tivo HD and this Mcard is working for now. I don't have any premium channels so I can't check on that but I'll see if any channels are missing or giving trouble once I am done watching football.

    I don't know if this is a sign that TWC is introducing Mcards in Queens or if they were low on cards and didn't realize the difference between M and S cards. Either way I lucked out with my install despite my initial fears about having a new installer or defective cards.

    You don't have to do anything to get the signal. Since both the Series 3 and the TiVo HD have ATSC tuners, all you need to do is to plug it into the cable.

    However without Cablecards (or a digital cable box), the cable companies can change the channel mappings at whim plus Time Warner does not does not supply guide information to Tribune for the unmapped channels.

    So, in order to record the HD feed of Las Vegas last night, I had to set a manual recording on channel 93-502 from 10-11 instead to TiVo knowing that HD version of Las Vegas was on channel 404 from 10-11.

    In Austin TWC provides guide data, so he is in luck in that aspect.

    Interesting, when they did mine back in december, I had a technician who knew all about the Tivos and know the exact person to contact at headquarters to get the cable cards setup. He started by running a line out to the street first and after a few minutes we couldn't figure out why the Tivo wasn't initializing the card (We started with card 1 first) and then found out that the cable wasn't connected outside (Ooops :rolleyes: ) anyway after the cable was connected card 1 authorized and then we tried card 2 but it had to be upgraded and took a couple of hours for it to upgrade then everything worked except for WTVD HD and a couple of other HD channels wouldn't work. Turned out that card 2 was not fully authorized but by the end of the night it was all working and has been working since then.

    Oh joy... It looks like one of the cable cards in our family room S3 has given up the ghost... Can't tune any non-analog channels when on that tunner..

    Did you reboot? 9.1 has a cablecard issue in S3 which causes the same problem you describ.

    Last week, I received a channel lineup change that removed channels 700-703. These carried HBO-HD, MAX-HD, SH-HD, and STARZ-HD programming. But these were also a mirror of the channels in the 600 range that carried the same content.

    Yesterday I checked all the channels. First, the east feeds were missing. Next I was not able to see a signal on 669 which is STARZHDP.

    So I call Customer Support {Start laughing here}. The first dweeb I talked to said that I should reset my TiVo and he would put me on hold while he got me directions on how to do that. Fifteen minutes later, I hung up.

    I called back and got another CSR who told me that I could NOT get eastern feeds with Cablecards. (HUH?). Then he said to tune 703 if I did not get 669 as it was a mirror. I tried to tell him that TW had reported those stations cancelled and I could not get a program guide on 703. That was like trying to explain how to make a souffle to a five year old.

    I reported this to TiVo. But I bet that I will never be able to record anything off of eastern feeds or STARZ HD. Well, I guess I can do a time and channel record. But certainly no Season Passes.

    Sign me "FRUSTRATED"

    Well, I just ran into this problem with cable card 2. I was running through some diagnostics on card 2 and testing some of the channels when the card stopped displaying the video. Diagnostics showed the card should be working. I could not see any reason for the video to stop showing up but figured I finally got hit by the 9.1 bug. I rebooted and everything is working again. Well, I hope they fix this bug soon because I can see this as a very bad bug that Tivo needs to fix ASAP (of course the way these things go, ASAP will probably be 2 to 3 months if we are lucky). I just hope they know where the problem is occuring in the software. It may take some time for them to figure out where the issue is. :(

    Didn't reboot but I pulled the card and re-inserted it went through guided setup again. It's recording something right now but I'll try it in the morning before I leave for work and see if it fixes it.

    And this likely shouldn't be in this thread any longer, but...

    Last night during playback of some recorded shows on one of the Tivos, I noticed that, randomly, there was a sort of dimming/flicker (very subtle) occurring. Maybe once every four minutes, if that, and not constant, but noticeable.

    Didn't even say anything for awhile, then asked the wife if she saw it. When even she said yes, I KNEW it had to be there. Again, very subtle. No clue what it could be. Only variables I can think of:

    Only noticed it so far on shows recorded pre-CC install.
    Recorded shows were set up to record on High (not Best) quality.
    Don't notice it on live watching.

    Yep, reboot brought it back... Odd. I'd have thought any transient data that or init sequence that might be needed to get the card working again would have been cleared/hit with a pull/insert + guided setup.

    Is this a bug that can hit you again (like the reboot loop bug that hit this same S3 during the NYE meet last year) or is it "generally a once you reboot it, it stays fixed" kind of thing?

    WAITING FOR SUPERVISOR CALLBACK


    Obviously I am not having any luck being able to enjoy my digital tier, nor HD channels on my S3 due to Comcast's inability to provide working cablecards. Not to mention the 4 different pricing schemes that various customer service reps have informed me of for using cablecards for Tivo.

    Anyone else in Atlanta having or have had the same issues? I need help, suggestions, phone numbers, customer complaint departments, etc.

    Wow. That's some supremely bad customer service you've got there, mx77m! On the fifth attempt, I'd make it perfectly clear that if there are no cablecards they BETTER tell you before you take off from work. If you were to give them as little notice as they've been giving you, that you can't meet them at your house, I'd bet they'd be pretty upset. Therefore, you have a right to be upset. In fact, I'd ask them how they'd feel if 4 times in a row, you decided to not meet them at your house, and also decided not to notify them until an hour or two after the appointment time.

    I am having a really really bad time trying to get both of my CableCARDs working properly. I have had my Series 3 for roughly 9 months now and I have had a recurring problem with my Cards which have now been switched out about six times. When they first get switched (Scientific Atlanta from Time Warner NYC) they work fine. After anywhere from a few days to a month or so Cable CARD 2 will stop working for non network channels. By stop working I mean that when the channel is switched from say NBC to ESPN, ESPN will come in for about three seconds, freeze then go to grey screen. If the problem goes unfixed for too long, the problem migrates to Card1.

    I just recently had them both replaced and CableCARD 2 has given out again. The CP screen reads as follows:

    Auth Status:CP Auth Received
    Prog number:467
    CCI byte:0x00
    ECM count:456
    EMM count:0
    Decryption status: No ECMs detected
    PowerKey status:Ready
    EID:0x0
    MKS period 100 seconds
    KSE:0

    Also worth noting is that on the HostID screen the CableCARD number has changed to
    0-000-000-000-000.

    I have talked to Tivo support and they insist that it is a CableCARD problem. They also mentioned that for it to work properly the signal strength under the channel menu needs to be around 95 (out of 100 it seems, not a dB reading). My signal strength has read from 77 - 88 but never 95. After I mentioned this to the last technician (who was one of the good ones) check the signal strength and said it should be fine. He also put an amplifier in line just to see what happens. Since then the signal strength has been holding steady at 82 (up from 77 when he first put it in).

    After so many tries with the exact same problem occurring I am getting very frustrated. TWNYC has actually been pretty helpful (mostly anyway) so I can't complain too much about them. My questions are: Am I screwed here? Is there anything TWNYC can do to get my signal strength up to 95? What does 95 translate to in dB? Is this really the problem? The technician hinted that a two way CableCARD may work better. Has anyone had problems with them? Does it ultimately come down to a crap shoot as to whether I get CableCARDS with longevity?

    I apologize if this has been covered earlier. I did try to search for a previously posted answer but there are quite a few posts here.

    Thank you very much for any help.

    Signal strength of 80 or above should be fine. The SNR number is more important and should be at least 32 preferabally 34. Look at the RS Uncorrected number... it should be 0 or low. EMM's dont come down this path anyway... you will see an OOB SNR value on down which should be in the mid to upper 20's IIRC.

    If you HostID went to all zeroes then there is definitely something wrong, I just cant say where (but I would bet its the Tivo if its happened multiple times on multiple cablecards). What happens if you reboot? With a zero host id, im surprised you have CP AUTH RECEIVED.

    FYI, the one card I had go bad had all zeros for the Host ID, I did the pull/insert + guided setup and it came back to a valid number but no (digital) channels. Did the reboot as suggested a few posts ago and it came back. YMMV.
