The circuit for superimposing a message input on a multi- image comprises a signal input unit (100) for processing a number of internal video signals and external video signal input, a multi- signal compressing unit (200) for compressing the input (100) signal to output a video signal, a message superimposing unit (300) for mixing and outputting the compressed signal to an external message signal, a signal output unit (400) for displaying the unit (300) output on a screen, and an audio signal processor (500) for selecting and outputting a desired audio signal from audio signals corresponding to a number of input image signals.
