Abstract:
1. A KVM switch connected between information processing apparatuses, and a remote terminal, the KVM switch comprising: a first input portion configured to input a plurality of video signals output from a first information processing apparatus, the plurality of videos signals output from the first information processing apparatus corresponding to different image data displayed on the remote terminal, respectively; a second input portion configured to input a plurality of video signals output from a second information processing apparatus, the plurality of videos signals output from the second information processing apparatus corresponding to different image data displayed on the remote terminal, respectively; a converting portion that converts each of the plurality of video signals input from the first input portion or the second input portion into image data different from each other which is configured to be displayed on a display of the remote terminal, the converting portion defining a screen on the display of the remote terminal for each of the plurality of video signals input from the first input portion or the second input portion such that a number of screens on the display is equal to a number of video signals input, dividing each of the plurality of video signals input from the first input portion or the second input portion into pieces of divided data for each of the defined screens, and adding information that decides a display position and a display size of an image related to the divided data for each screen of the display and type information of the video signal corresponding to the divided data to each divided data to generate the image data corresponding to the video signal; a transmitting and receiving portion that transmits each of the converted image data to the remote terminal, and receives various requests from the remote terminal; a switching portion that switches the plurality of video signals input from the first input portion to the plurality of video signals input from the second input portion when the transmitting and receiving portion receives a switching request for switching from the first information processing apparatus to the second information processing apparatus from the remote terminal; and a first output portion that outputs data which the transmitting and receiving portion receives from the remote terminal, to the first information processing apparatus, and a second output portion that outputs data which the transmitting and receiving portion receives from the remote terminal, to the second information processing apparatus, wherein when the transmitting and receiving portion receives the switching request, the switching portion switches an output source of the data received from the remote terminal from the first output portion to the second output portion.
