I'm interested to know if it is possible to add a ticker to a TV broadcast.
That is, receive the TV broadcast and add a ticker display to it before it hits the screen.
I've seen (via google search) a few companies that offer this type of thing: VideoTicker & WorldFlash TVTicker, but these appear to be aimed at commercial broadcasters rather than the home user.

Note that I'm after realtime solution, not a save and add subtitles later solution.

Anyone got any ideas, suggestions, alternatives ?

Thanks.
