Hi
Although I am no expert on broadcast video but I think this is a problem of compositing two video streams realtime.
No. It is about composting rendered text and a stream.
One is the broadcast stream and the another is the text
or advertisement graphics that need to be overlaid on the broadcast.
This is about composting pixmaps and stream.
(haha i love spell check).
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,
Rubbish. Take a look at gstreamer.
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.
