It depends on the
camcorder. Generally, when you connect the AV-out - specifically to the Yellow RCA connector that sends the analog, composite video signal - to a TV's AV-in, that works. It does not matter if the camcorder is HD or not. I do that with my high definition camcorders when I use a camera crane - the camcorder's viewfinder or LCD panel is too far away to see/use. A shielded extension cable can be used if the camcorder's cable is not long enough.
