A CD player for reproducing signals stored on CD-OK and video compact disks (VCD) includes a first controller for controlling CD-OK reproduction; a second controller for outputting audio and video data for CD-OK reproduction and a control signal for VCD reproduction; a decoder for restoring compressed video and audio data; a first storage for storing control data for processing CD-OK signals during CD-OK reproduction and for storing control data for processing VCD during VCD reproduction; a second storage for storing data for a still screen and superposed data of the CD-OK disk during CD-OK reproduction and for storing video and audio data during VCD reproduction; a first digital-to-analog converter for converting the CD-OK video data output from the second controller into an analog image signal; a second digital-to-analog converter for converting image data output from the decoder into an analog image signal; a first switch for selecting one of the image signals output from one of the digital-to-analog converters; a video encoder for converting the image signal output from the first switch into a composite image signal; and a second switch for selecting an audio output, thus integrating CD-OK and VCD reproduction circuits to reduce manufacturing costs for an integrated system.
