A KVM system having a plurality of adapters and a KVM switch, comprising:
- each of the plurality of adapters including:
- an analog-to-digital converting portion that inputs an analog video signal output from one of a plurality of output terminals included in an information processing apparatus, and converts the analog video signal into a digital video signal;
- a serial data converting portion that converts the digital video signal into serial data;
- and
- an optical signal/differential signal converting portion that converts the serial data into an optical signal or a differential signal, and outputs the optical signal or the differential signal to the KVM switch;
- the KVM switch including:
- a storing portion that sequentially stores the optical signal or the differential signal output from each of the plurality of adapters as video data;
- a difference detecting portion that detects difference video data between present video data for one screen and previous video data for one screen with respect to the sequentially stored video data;
- a transmitting portion that adds identification information of a corresponding analog video signal to the detected difference video data, and transmits the difference video data to which the identification information of the corresponding analog video signal is added, to a remote terminal via a network;
- and
- a plurality of connecting portions that are connected to a plurality of displays, and an identification information displaying portion that displays pieces of identification information of respective corresponding connecting portions on the plurality of displays in response to a depression of a given switch or the input of a given key.
