This means that the voice recognition processing for the voice signal, such as A / D conversion to generate a digital signal of the input voice signal. In this example, a digital signal of the actual voice 'ABC' (for example, an ASCII code of ABC can be an example).

The macro function execution unit 303 selects a macro function mapped (set) to the voice 'ABC', for example, 'TV mode setting + button 1 selection + button 1 selection' mapped to the word 'ABC'. It executes a macro function that presses a series of button combinations such as 'Select OK button' to bring the same effect as an input effect by a button (S32). As a result of executing a macro function, a series of button combinations is executed. This is the key value generated by the actual press. In order to execute the macro function, the macro function mentioned above is set in advance as a premise, and the functions are stored in the macro function DB, the DB is searched before the macro function is executed, and it is first determined whether the function is stored. The result of executing the macro function is an input item that the user wants to realize by voice. According to this example, the broadcast screen of ABC station will be presented through the DTV screen. The speech recognition function provided by the present invention has an effect of facilitating an input for performing various functions of the DTV, such as volume up / down, application selection, and control buttons, as well as the channel searched by the user. to provide.
