Abstract
Karaoke is provided more easily and flexibly by recording video signals from multiple video sources on a disk; selecting one of those sources as desired; and reproducing the signals from that source along with either the output of a video camera or graphics data. The graphics data is recorded on the disk with the video source signals in multiplexed fashion, along with selection signals. When the multiplexed signals are demultiplexed, chroma-key composite circuitry effects desired superimposition of a video camera output on the source video signals.
