TV through PC with multi media overlay

[Jeff12518]

I wish to set up a PC based media server in our legion. I would like to run the cable feed through a TV card & then overlay service announcements onto the screen at scheduled times. I will buy a desktop box and add a tuner card. Ubuntu 10.04 is my OS of choice.

I am not sure which software will allow me to place our text as an overlay, or subtitle, onto the existing broadcast feed. We would also like to place multi-media content onto the screen. This would also run at scheduled intervals. This would allow our daily special events to overlay whatever we have on our TV sets in the lounge.
