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.

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.

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.

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,
NGC


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.
