Abstract

A communication system is disclosed that includes a first device that performs communication of information with the outside; a second device through which the information is input and output; and a relay device that performs wired communication with the first device and wireless communication with the second device to relay the information between the first device and the second device.

Claims

1. A communication system comprising:

a first device that performs communication of information with an outside;

a second device through which the information is input and output; and

a relay device that performs wired communication with the first device and wireless communication with the second device to relay the information between the first device and the second device.

2. The communication system according to claim 1, wherein

the first device receives a broadcast, and the relay device performs short-range wireless communication with the second device to transmit the broadcast received by the first device to the second device.

3. The communication system according to claim 1, wherein

the first device includes a broadcast reception section that receives a broadcast, a processing section that processes a signal received by the broadcast reception section, and a first interface section that transmits the signal processed by the processing section to the relay device.

4. The communication system according to claim 1, wherein

the relay device is capable of constituting a wireless communication network.

5. The communication system according to claim 1, wherein

the first device and the relay device are directly connected to each other through a connector.

6. The communication system according to claim 1, wherein

at least the relay device and the second device perform wireless communication through ultra-wide band wireless communication.

7. The communication system according to claim 1, wherein

at least the relay device and the second device have an ultra-wide band antenna.

8. The communication system according to claim 6, wherein

at least the relay device and the second device measure a position and a distance with a position and distance measuring function of the ultra-wide band wireless communication and form a network based on a result of measuring the position and the distance.

9. The communication system according to claim 1, wherein

the first device receives information transmitted from a device present in a specific area and transmits the information to the second device via the relay device.

10. A communication method comprising the steps of:

performing communication of information with an outside using a first device; and

performing communication of the information wirelessly between a relay device connected to the first device and a second device through which the information is input and output.
