ABSTRACT:
A compact disk player incorporated television receiver includes a television signal receiver, a compact disk player having a song accompaniment function, a video signal processor for selectively receiving and processing a video signal output by the television signal receiver or a video signal output by the compact disk player and displaying the processed signal on a monitor. The device also contains an audio signal processor and a power source for generating voltage signals to supply power to the television signal receiver, the monitor, and the compact disk player. Also, a television controller is provided for controlling the supply of the voltage signals by the power source depending on whether the device is operating in a television mode or compact disk mode. The device operates in a television mode or a compact disk mode based on control signals input via an instruction input unit. Accordingly, when an audio compact disk is being played by the compact disk player (i.e. the device is operating in the compact disk mode), a voltage signal is generated so that a monitor is turned on only when on-screen characters are being displayed and is turned off after the characters have been displayed for a predetermined period of time. Furthermore, the television controller controls whether the video signal processor and audio signal processor receive video and audio signals from the television receiver or the compact disk player.
