In addition, a broadcasting channel or a language constituting the broadcasting content may be defined in a separately provided field (hereinafter referred to as a 'language field') ('ContentLanguageSpecial') for defining the language information in relation to the broadcasting contents.

For example, broadcast-related information may include a plurality of language fields, and each language field may define a different language.

In particular, according to FIG. 6B, the keyword data defined in the keyword field can be expressed in a language defined in the language field. Further, when there are a plurality of languages defined in the language field, keyword data can be defined in each language.

Therefore, the control unit 180 can extract the keyword data defined in the keyword field of the broadcast-related information.

The extracting step (S503) is performed in the case of receiving the broadcast-related information, entering the broadcast search mode using the keyword data, updating the broadcast-related information, or inputting a command signal for keyword data extraction from the user .

The mobile terminal 100 may store at least one of the broadcast related information received in the receiving step S501 and the keyword data extracted in the extracting step S503 in the memory 160 under the control of the controller 180 (S505).

The mobile terminal 100 may store the broadcast related information received in the receiving step S501 in the memory 160 and then extract the keyword data (s) from the stored broadcast related information.

In storing keyword data, the mobile terminal 100 may store keyword data in a plurality of storage languages including a language defined in a language field. At this time, the storage language can be set by the user or the mobile terminal 100.

For example, when the language defined in the language field is 'English' and the storage languages are 'English', 'Korean', 'Japanese', and 'Chinese' And the extracted keyword data can be stored in Chinese.

Meanwhile, the broadcast-related information or keyword data may be stored in the identification device 310 detachably attached to the mobile terminal 100. Therefore, when the identification device 310 mounted on the mobile terminal 100 is mounted on another terminal, the broadcast-related information and keyword data stored in the identification device 310 can be used by other terminals. On the other hand, when another identification device installed in another terminal is mounted on the mobile terminal 100, the broadcast-related information and keyword data stored in the other identification device can be used by the mobile terminal 100.

The mobile terminal 100 receives search information composed of at least one character from the outside through the user input unit 130 (S507).

For example, the user can input search information using a keypad composed of a plurality of buttons to which respective characters are assigned, or a virtual keypad provided on the touch screen. Alternatively, the user can input a character as voice through the microphone 122.

In the input step (S507), the search information may be input directly by the user or input using a keyword list. Here, the keyword list may mean a list composed of at least one keyword data included in the broadcast-related information.
