摘要

A network system includes a first communication device, a second communication device and a server. The communication device includes a storage unit storing first device information indicating a function of the communication device, and a communication unit for receiving second device information indicating a function of another communication device from the other communication device, transmitting the first and second device information to the server, and receiving first control information used by the first device from the server.

主权项

1. A network system comprising a first device, a plurality of second devices, and a server,
said first device including:
a first storage unit configured to store first device information indicating at least one of a function of said first device and a type of said first device; and a first communication unit configured to receive, from a plurality of said second devices that are arranged nearby the first device, second device information indicating at least one of a function of said second device and a type of said second device, to transmit said second device information received from the plurality of second devices that are arranged nearby the first device and first device information to said server, and to receive first control information used by said first device from said server, said second device including:
a second storage unit configured to store said second device information; anda second communication unit configured to transmit said second device information to said first device, and to receive second control information used by said second device from said server, said server including:
a server storage unit configured to store a plurality of functions, each of said plurality of functions being associated with said control information for using the function;a control unit configured to extract said first control information for implementing a user interface via which said first device accepts a command from a user and second control information for remotely controlling said first device based on said first and second device information, by referring to said server storage unit; anda server communication unit configured to transmit said first control information to said first device, and to transmit said second control information to each of said second devices that are arranged near the first device, wherein said server storage unit stores the information indicating the function, the first control information, and the second control information, and wherein said control unit is configured
to extract said first device information and said first control information being associated with the content transmitted from said server to said first device to display the content based on the control information associated with the content, andto extract said second device information and said second control information being associated with the content transmitted from said server to said second device to display the content based on the control information associated with the content.
