Abstract
A display control unit causes a projector display unit to display host-specifying information based on a first host address of a first IP address allocated to a projector. A communication establishment unit specifies, when the host-specifying information is inputted via an input unit, a third IP address based on the inputted host-specifying information and a second network address of a second IP address allocated to a communication terminal. The communication establishment unit executes communication establishment processing to establish communication between the projector and the communication terminal, using the third IP address.
Claims9
A communication system comprising:
- a display device which has a display unit and a first communication unit communicating via a communication network and to which a first IP address including a first network address and a first host address is allocated;
- and
- a communication terminal which has an input unit and a second communication unit communicating via the communication network and to which a second IP address including a second network address and a second host address is allocated, wherein
- the display device includes a display control unit causing the display unit to display host-specifying information based on the first host address, and
- the communication terminal includes a communication establishment unit which executes, when the host-specifying information is inputted via the input unit, communication establishment processing to establish communication between the display device and the communication terminal, using a third IP address specified based on the inputted host-specifying information and the second network address.
A communication method executed by a display device which has a display unit and a first communication unit communicating via a communication network and to which a first IP address including a first network address and a first host address is allocated, and a communication terminal which has an input unit and a second communication unit communicating via the communication network and to which a second IP address including a second network address and a second host address is allocated, the method comprising:
- a display control step of displaying host-specifying information based on the first host address, on the display unit by the display device;
- and
- a communication establishment step of executing by the communication terminal, when the host-specifying information is inputted via the input unit, communication establishment processing to establish communication between the display device and the communication terminal, using a third IP address specified based on the inputted host-specifying information and the second network address.
A display device comprising:
- a display unit;
- and
- a first communication unit communicating via a communication network, wherein
- the display device includes a first IP address allocated thereto, the first IP address includes a first network address and a first host address,
- the display device includes a display control unit, the display control unit causes the display unit to omit displaying information about the first network address, of information about the first network address and the first host address included in the first IP address, and the display control unit causes the display unit to display only host-specifying information based on the first host address.
