Abstract
Various kinds of digital broadcast recording and playback are supported even when PSI (Program Specific Information) or SI (Service Information) is unknown. A management area of an information storage medium used in digital broadcast recording has management information for each broadcast station, and also management information of a type that does not specify any broadcast station. 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.
Claims20
An information storage medium configured to record a given digital stream signal, wherein
- the information storage medium has a management area and a data area,
- the data area is configured to separately record data of the digital stream signal as a plurality of objects,
- the management area is configured to have management information for each output source of the digital broadcast signal or for each broadcast scheme of the digital stream signal, and to have time map information for each output source of the digital broadcast signal or for each broadcast scheme of the digital stream signal, and
- the management information for each output source of the digital broadcast signal or for each broadcast scheme of the digital stream signal is configured to include information indicating a size of the time map information.
An information storage medium configured to record a digital stream signal which is encoded by MPEG and is output from a broadcast station, wherein
- the information storage medium has a management area and a data area,
- the data area is configured to separately record data of the digital stream signal as a plurality of objects,
- the management area is configured to have management information for each broadcast station or for each broadcast scheme of the digital stream signal, and to have management information of a type that does not specify the broadcast station or the broadcast scheme, and
- the management information of the type that does not specify the broadcast station or the broadcast scheme is configured to include information indicating invalidity of information associated with broadcast contents.
An information storage medium configured to record MPEG transport stream data and MPEG program stream data as given digital stream signals, wherein
- the information storage medium has a management area and a data area,
- the data area is configured to separately record the MPEG transport stream data and the MPEG program stream data in independent files as a plurality of objects,
- the management area is configured to record management information that manages the entire digital stream signal, management information for the MPEG transport stream data, and management information for the MPEG program stream data, and
- the management information is configured to describe at least one of information indicating whether or not the digital stream signal of interest is a progressive mode signal and information indicating whether or not the digital stream signal of interest is a high-definition video signal.
