Hi Although I am no expert on broadcast video but I think this is a problem of compositing two video streams realtime. One is the broadcast stream and the another is the text or advertisement graphics that need to be overlaid on the broadcast.
Perhaps the search query linked below might help somehow get some initial direction. http://www.google.com/search?q=video+broadcast+mixing However, I doubt there is a FOSS software package that would do this out of the box for a live broadcast stream considering FOSS is severely lagging behind on the video compositing scenario, or so I think. I would be glad to know if there is a FOSSy solution to this problem or for video compositing in general. Back to your problem, i think most cable tv operators do this (using proprietary software and/or hardware equipment), so perhaps consulting a few of them would be a good idea to get started.
