KR970050919A - Multi-screen Compact Disc Player - Google Patents

Abstract

The present invention provides a multi-video compact disc player that simultaneously plays back a plurality of video compact discs and implements the plurality of reproduced videos on a single video display device so that a plurality of videos can be simultaneously viewed using a single video display device. To provide a multi-screen playback device.

To this end, the present invention, the control function setting unit 10 that can set the multi-screen playback mode, and the overall control to control the entire device so that a plurality of images currently being reproduced in the live multi-screen playback mode simultaneously displayed on a single CRT A control unit 12, a plurality of recording information reproducing means 16, 18; 28, 30 for reproducing video / audio information recorded on a plurality of video compact discs, and processing MPEG video signals from the plurality of recording information reproducing means A plurality of MPEG video signal processing means (20, 23; 32, 34), a plurality of buffers (24; 36) for temporarily storing / outputting RGB color signals from the plurality of MPEG video signal processing means at a constant speed, and the plurality of An address generator 40 for determining the memory / output speed for the RGB color signals applied to the buffers 24 and 36, and a multiplexer for receiving and processing the RGB color signals outputted from the buffers 24 and 36; 42), the multiplex A selecting section 44 for alternately providing the multiprocessing buffer select signal in (42) to the multiplexer 42 at regular intervals, and on the CRT encoding the multiple signal from the multiplexer 42; It is configured to include an RGB encoder 46, there is an effect that can view a plurality of screens using a single CRT.
