Method and apparatus for storing broadcast program

A method of storing a broadcast program, the method comprising:

• generating an audio/video (A/V) file, an application file, and an electronic program guide (EPG) file by processing A/V signals, application information, and EPG information, respectively, which are included in an broadcast program transport stream;
• generating a synchronization file comprising storage information for the A/V file, storage information for the application file, and storage information for the EPG file, and that is used to synchronize the A/V file, the application file, and the EPG file;
• and
• storing the A/V file, the application file, the EPG file, and the synchronization file, in a storage unit, in non-volatile storage,
• wherein at least one of the generating an A/V file, an application file and an EPG file, and the generating of a synchronization file, is performed by a processor,
• wherein the storage information for the A/V file, the storage information for the application file, and the storage information for the EPG file comprise directory location information specifying directories where the A/V file, the application file and the EPG file, respectively, are to be stored, and
• wherein the storage information for the A/V file and the storage information for the application file are information not corresponding to any information provided in the first EPG file.

A non-transitory computer-readable storage medium storing a computer program for executing a method comprising:

• generating an audio/video (A/V) file, an application file, and an electronic program guide (EPG) file by processing A/V signals, application information, and EPG information, respectively, which are included in an broadcast program transport stream;
• generating a synchronization file comprising storage information for the A/V file, storage information for the application file, and storage information for the EPG file, and that is used to synchronize the A/V file, the application file, and the EPG file;
• and
• storing the A/V file, the application file, the EPG file, and the synchronization file, in non-volatile storage,
• wherein the storage information for the A/V file, the storage information for the application file, and the storage information for the EPG file comprise directory location information specifying directories where the A/V file, the application file and the EPG file, respectively, are to be stored, and
• wherein the storage information for the A/V file and the storage information for the application file are information not corresponding to any information provided in the EPG file.

An apparatus for storing a broadcast program, the apparatus comprising:

• a synchronization unit which generates a synchronization file comprising storage information for an audio/video (ATV) file, storage information for an application file, and storage information for an electronic program guide (EPG) file, and that is used to synchronize the A/V file, the application file, and the EPG file;
• and
• a storage unit which stores the A/V file, the application file, the EPG file, and the synchronization file, in non-volatile storage,
• wherein the storage information for the A/V file, the storage information for the application file, and the storage information for the EPG file comprise directory location information specifying directories where the A/V file, the application file and the EPG file, respectively, are to be stored, and
• wherein the storage information for the A/V file and the storage information for the application file are information not corresponding to any information provided in the first EPG file.
