1. An apparatus for remotely controlling a remote computer system installed at a remote location using a local master apparatus, wherein:

  • (a) said master apparatus comprises,a master input device for producing an operation signal,master transmission means, connected to said master input device, for encoding the operation signal from the master input device, and transmitting the encoded operation signal to said remote computer system via a first communication line,a master computer which can perform a test operation corresponding to said encoded operation signal transmitted to said remote computer,decoding means, connected to said master transmission means, for decoding an encoded operation signal from said master transmission means,means, connected to said decoding means, for supplying a decoded operation signal from said decoding means to said master computer, said master computer performing said test operation in response to said decoded operation signal and producing a data processing result, anda first display device for displaying the data processing result of said master computer; and

    (b) said remote computer system comprises,a remote computer for receiving the encoded operation signal transmitted from said master apparatus through said first communication line, for decoding the encoded operation signal into the operation signal, and for performing a data processing operation corresponding to the test operation performed by the master computer in response to the operation signal and outputting a video signal as a product of said processing;

    wherein said apparatus for remotely controlling further comprises;

    remote transmission means, connected to said remote computer, for encoding the video signal output from said remote computer, and transmitting the encoded video signal to said master apparatus through a second communication line;

    master reproduction means for receiving the encoded video signal transmitted from said remote transmission means through said second communication lines, and decoding the encoded video signal to the original video signal; and

    a second display device, connected to said master reproduction means, for displaying an image in response to the video signal decoded by said master reproduction means so that an operator can compare the data processing result displayed by said first display device with said image displayed by said second display device to confirm a correspondence therebetween.
