Abstract
Various kinds of digital broadcast recording and playback are supported even when PSI (Program Specific Information) or SI (Service Information) is unknown.

The management information of the type that does not specify any broadcast station includes information indicating invalidity of information (PSI, SI) associated with broadcast contents.
