For example, when it is decided that a television broadcast system is PAL, it is further decided whether the system is PAL-BG. When so, it is decided whether the television broadcast system has a CH characteristic of, for example, Italy in PAL-BG mode. When it is decided that a CH characteristic of Italy is available, a default language is set to Italian. When it is decided that a CH characteristic of Italy is not available, the default language is set to German. When it is decided that the television broadcast system is PAL-I, the default language is set to English. When it is decided that the television broadcast system is not PAL-I, the language set at the time of factory shipment is set.
