Abstract:
1. An information signal transmission system, comprising: a network interface connected to a first presentation device and to a second presentation device through a network, a control component connected to said network interface, including a microcomputer to control the information signal transmission system; an information signal component connected to said control component and to said network interface, including a reproduction block to reproduce an information signal received from said control component and an output block to code an information signal reproduced by said reproduction block and output the information signal to said network interface; and an identification component connected to said control component; wherein while said information signal component outputs an information signal to said first presentation device through said network interface, said identification component stores identification data indicating an identification code identifying a user, when said control component receives a control request from said second presentation device through said network interface and said control request includes identification data indicating said identification code identifying said user, said identification component determines that the identification code of said identification data in said control request matches the identification code of said identification data stored by said identification component and sends a change device request to said control component, said change device request indicating said second presentation device, and when said control component receives said change device request indicating said second presentation device, said control component causes said information sign al component to begin to output said information signal to said second presentation device through said network interface.
