cable-card ready tv card
 
hay guys anyone know of a decent cable-card ready pci tv card that does hardware encoding?

Hardware encoding isn't necessary with cablecard devices. It just decrypts the video stream and stores it verbatim, which is good because your cable company has encoding hardware that is far more efficient (better quality while having a reduced file size) than any consumer product could ever be, and thus by extension you gain the same benefit since you don't have to encode it again.

Unless you're talking about when you tune to analog channels.

Cablecard is still mostly a bust, you can't buy the cards retail, and they require your cable company to send someone in to slide the card into your machine. Even then, you'll have a hard time getting the decoder cards from your cable company.

ps: IPTV is worse when trying to do the same things.

ok here is what im trying todo. ive been using an orb server now for a few years and have been using it with a mutli-tuner hardware tv card on comcast tv. comcast has its first 90 channels in the clear on its analog system so no box requered. with my current setup i can stream about three live tv programes at a single time because the decoder cards are hardware based, if this was a software based car i would be lucky to get one stream at a time. well now i switched to verizon fios tv and the first 49 channels are in the clear on verizons analog system. most of these channels are nothing more then local broadcast crap. so in order to get above channel 49 i need a QAM compatible set-top box or a cable-card ready tv card in order to get the channels on the new system. i hope that conveys what it is im looking todo...

i cant deny that cablecards suck but when the new TV companies are forced to use encrypted QAM by the broadcasters you sort of have no choice but to use it and the thing about the decoder cards they are pretty much none existance.

i dont know about that, ive been doing it now for several years and i have found it to be indispensible with my work schedule and the quality is very good depending on what your watching.

I think the same thing would still apply, with the exception being the analog channels. The reason you'd need that hardware encoding with another card is because it needs to do mpeg-2 compression before it can send it over the network (otherwise there wouldn't be enough bandwidth.) But the CPU isn't going to be able to easily compress 3 simultaneous streams into mpeg-2 at once.

With cablecard it doesn't have to; the stream is already compressed anyways. It can just buffer it to the hard disk and then send it over the network to the clients on the fly as requested.

The trouble is finding a cablecard tuner that supports M-Cards so that you can have mutiple tuners at once. I don't know if any support that.

There are both actually. As for digital cable, I know ATI makes one cablecard PCI receiver which is HD capable. As for satellite, you can use just about any dvb-s compliant PCI card to illegally decrypt dishnet (and receive all channels, including ppv, porn channels, etc) I don't know much about cablecard, but the later setup would cost you roughly $150 (for the dish and card) and take about a week or so for you to figure it all out (At least as far as setting up the dish, operating the emulator, rotating the keys, etc. Will take even longer if you want to figure out how the emulator actually works, which can be useful.)

I've never done either setup before, but I used to get directv for free a while back, and I am well aware of the concepts and other whatnots for getting dishnet free, but lost interest in that a long time ago.

theres a lot of problems with cable card. (Mostly due to a lot of corporate resistance and lack of investment.)

The primary one: It does not support any client->host interactive functions:
particularly: video on demand. Zero support by design.

The cable companies hate CC it as it cuts into their 'monthly box rental' fee and adds another hardware to support.

its based upon the (nearly) obsolete passive viewer model. An advanced channel selector (decoder) it you will.

the companies "COULD" go beyond the specs, but why should they spend the development money to get lower revenues.

It was a crippled spec from the beginning.

True vidiots (myself included) are already on HD-DVRs. cable cards would be going backwards 5-10 years for us.

What I would love to see is just one box that can decrypt the signal from your tv provider and give you the channels you need. Then that box would send out an unencypted signal which can be split and run to anything you want in your house. It would be so much easier than having a box for each device that you want to connect.

Actually there is a common misconception about cablecard in this regard. Two way communication is quite possible with the existing cablecard hardware, just nobody has agreed on a standard yet as to how this communications will be handled. When a standard is agreed upon, and devices start supporting that standard, the existing s-cards and m-cards will work just fine with it.

I would differ there. Cable company provided DVR's suck balls compared to some DVR's out there. Using one of those motorola or scientific atlanta cable boxes is going back 5-10 years in DVR technology.
