DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving and recording apparatus and a receiving and recording method for recording program data and program guide data.

[0002]

2. Description of the Related Art In recent years, digitalization of television broadcasting has been rapidly progressing. Perfect TV (SkyPerfecTV)
Digital broadcasting using communication satellites (CS) such as TV and DirecTV has already started.
From 0 years, digital broadcasting by broadcasting satellite (BS)
Digital broadcasting by terrestrial broadcasting is planned from the year 2003.

In digital broadcasting, program accompanying information such as program guide data (EPG) is transmitted in addition to program data as program contents. The program guide data includes data such as broadcast time, channel, characters, genre, etc. of the program, and by using the program guide data, it is possible to search for a favorite program from a multi-channel program or to make a recording reservation. It can be done easily.

[0004] Program guide data is sequentially transmitted at predetermined time intervals. For example, even when a program is extended or the broadcast time of a program is changed, recording is performed using newly transmitted program guide data. It is also possible to change the reservation time.

ISD proposed by NHK (Japan Broadcasting Corporation)
In B (Integrated Services Digital Broadcasting), program guide data is composed of a program index and a program index. The program index describes information on the entire program, whereas the in-program index describes information on each scene in the program. By using the in-program index, you can search for each program scene,
Part of the program can also be recorded.

When program data is recorded on a portable recording medium such as a DVD-RAM, program table data can be recorded together with the program data. Thereby, DV
It is also easy to search what program is recorded in the D-RAM.

[0007] The program table data may be transmitted simultaneously with the corresponding program data, or may be transmitted before and after the corresponding program data. For example, the in-program index may be generated after the broadcast of a program such as a live broadcast, and may be transmitted after a predetermined time has elapsed after the end of the broadcast of the program data.

[0008] When the corresponding program guide data is transmitted after a relatively long time has elapsed since the recording of the program data on the portable recording medium, the portable recording medium may have already been removed from the recording device. In this case, the program guide data cannot be recorded on the portable recording medium.
