[Skunkworks] PC to TV video splitters

Hi people, I have an application installed on a PC which generates about 10 graphs of real time data, I would like to output these graphs to about 4 sony bravia TVs. My preliminary investigations indicate that a video splitter would do that. I have never used one before, any skunks with more details? Any local suppliers? What if I wanted to have the 10 graphs be like kawaida TV channels so that I can tell users something like; "Switch to channel 5 to see report X", any leads on I can do that? Thanks!
