Upon switching operation of a remote control device, CPU 11 in a karaoke system judges whether an entered singer's name or song title consists of a single character or the entered singer's name or song title consists of two and more characters. When the entered singer's name or song title consists of a single character, a prefix search process is executed to search for information starting with the entered character. When the entered singer's name or song title consists of two and more characters, a partial match search process is executed to search for information including a character string of the entered characters. Therefore, a user is not required to set whether to execute the prefix search or to execute the partial match search, and is allowed to search for his or her desired information, only by entering a single character.
