    Hi folks,

    I have a question that might be alrady answered but as I don't know
    even what to look for, here is my question.

    I want a TV card that is capable of presenting several channels at the
    same time in high resolution (the highest possible). Then I want to
    attach a streaming server to this card and configure it to multicast
    each channel found on TV card. Then I want to connect a client on
    another computer in my LAN to this server and choose a channel to
    watch. Each client that connects may choose a channel (stream) to watch
    independantly of others.

    I am aware that this may eat up server resources quickly but I would
    appreciate solution that says "this card may play nnn channels
    simulateously, each channel requires mmm MB of memory, this server may
    provide as many multicast streams as you want but each stream requires
    kkk MB of memory and bbb bandwidth..."

    I'd very much appreciate Linux solution.

    Thanks in adavnce,

    You don't seem to state what the source(s) of your video is(are), for
    example files on disk, OTA television transmissions, a cable
    television feed, etc., but VBrick Systems may offer a solution that
    fits your needs, although I'm sure that other products from other
    vendors might also be suitable.

    Thanks for the reply. I looked at VBrick and they indeed have what I
    want but on a large scale. I was having in mind a small LAN of 3-4
    computers at my home watching cable TV.

    The main component in my setup is a TV capture card that is capable of
    giving several channels at once. I think that software configuration is
    more or less solved already.

    I'm assuming that you are in the US because that is the locale in which I am
    familiar with the workings of the television system. In other parts of the
    world other solutions may be viable--when asking TV questions it is
    important to say where you are as there are several mutually incompatible
    TV broadcast systems in use around the world.

    If you want to capture high definition off of cable then you're going to
    need 4 cable boxes to record 4 channels unless you're willing to settle for
    the few that are not encrypted, and you will need to record from the cable
    boxes via the Firewire port. The unscrambled HD signals on cable can often
    be captured using a QAM-capable capture board, but they are generally
    restricted to the local channels and a few preview channels. All others
    have to come through the cable box and the only output on the cable box
    that gives a recordable signal (unless you want to spend for
    professional-grade capture equipment that costs thousands of dollars per
    board) is the Firewire port. Even then it may not be active--the cable
    providers are _supposed_ to provide HD subscribers a box with an active
    Firewire port but not all of them do unless you raise Hell about it.
