ABSTRACT:
The digital broadcasting station describes the first unique information as identification information in addition to the event identification prescribed by ARIB standard as opposed to LIT describing the detailed information of local event. The first unique information is for example a date of amended Julian calendar. Therefore, the digital broadcasting receiver can identify the digital broadcasting program uniquely for a long term based on the event identification and the first unique information. Besides, the digital broadcasting station and the digital broadcasting receiver with the use of program extended information such as LIT are not yet put to practical use and so the existing digital broadcasting receiver had to be changed neither.
