A great way to do this live is with a video mixer.
Video mixers support 2 or more channels, and include a chroma key effect. Chroma key one channel, and have the other channel beneath it.

These machine can run pretty expensive though, and the older ones only deal with analog video, so anything complex (and importing) would be a little more difficult.
Nonetheless, just having a video playing in the background and having your subject chroma keyed, a video mixer would do the job well and relatively easily.
