## Abstract

There is provided a terminal device including a detection unit configured to detect a relay device, a reproduction unit configured to reproduce content, a transmission unit configured to transmit the reproduced content to the detected relay device, and an acquisition unit configured to acquire a response returned from one of identification server devices to the relay device according to a query, the response corresponding to an identification result of the content in such a way that the relay device extracts signature data representing a characteristic of the content from the content, generates the query including at least the extracted signature data, and transmits the generated query to the identification server device to request identification of the content.

## Claims

### Claim 1

A terminal device comprising:
a detection unit configured to detect a relay device;
a reproduction unit configured to reproduce content;
a transmission unit configured to transmit the reproduced content to the detected relay device; and
an acquisition unit configured to acquire a response returned from one of identification server devices to the relay device according to a query, the response corresponding to an identification result of the content in such a way that the relay device extracts signature data representing a characteristic of the content from the content, generates the query including at least the extracted signature data, and transmits the generated query to the identification server device to request identification of the content.
