[LINUX] Question for TV cards

[atbiz]

Hi,
I'm working to build a videocasting solution based on XBMC.
I explain first what I'm doing then I'm gonna ask you to help me to go in the right direction.
1 - The Server will be with Linux (Ubuntu 9.04), running XBMC and maybe MythTV.
2 - It will be connected to a satellite free to air reciever with TV tune card, to recieve the video and audio signal.
3 - A channel will be recieved in XBMC then streamed directly to the Internet.
4 - An Internet user will be able to watch it live from my web site. The web site has a protected page getting the streaming from my XBMC/Ubuntu Box
Here is a textual schema:
[Satellite Reciever]---composite cable---[TV card with Ubuntu & XBMC & ]---RG45 cable---[Router+Modem DSL High Speed]----(Internet)---[Internet Web Server]---(Internet)---[User with Web Browser]

Now my questions are:
1 - Is there a list of TV Cards that support composite cable and support Linux+XBMC?
2 - Is there any other alternative or a different architecture to realise what I'm trying to do?
Thanks in advance.

Notice: I'm new.
I mean by TV tune card: a TV card to recieve a full video/audio signal from a a cable or a reciever or a video player. So I think its correct name is DVB card... is it correct?

Hmm XBMC is basically frontend, you don't have to worry about that. What you need is to look at this wiki http://www.linuxtv.org/wiki/index.php/Main_Page and see which card is supported by Linux and buy one.

Then you need to decide which backend you wanna use (mythtv, vdr...).

I have 1 DVB-T and 1 DVB-S2 connected to my server using vdr as backend and it works great, i use vdr-streamdev plugin for streaming http://streamdev.vdr-developer.org/

vdr -> xbmc is new but they are working on it, check out this thread http://xbmc.org/forum/showthread.php?t=45314

To clarify; XBMC has no native support for TV cards, you need to use a backend like MythTV or VDR.

So XBMC is only a frontend in that regards.
