I have a Samsung HDTV, model # LN32C350 Amazon.com: Samsung LN32C350 32-Inch 720p 60 Hz LCD HDTV (Black): Electronics . (It's connected to a Logitech Revue.) YouTube has a number of musical videos available for Karaoke. I was wondering whether I could just buy a wireless microphone, plug it into this Samsung TV and overlay the voice (karaoke) while a YouTube instrumental played in the background. Is this possible?
