[0002]

2. Description of the Related Art In a conventional program receiving device (broadcast receiving device including digital broadcasting, etc.), a broadcast program is received, and the received program is recorded in a storage medium and reproduced.

However, the conventional program receiving apparatus is not supposed to update the contents of a part or all of the recorded program, and when the program is updated, this is automatically detected. Recording updated programs was not considered.

Further, in recent years, a program receiving apparatus having a large-capacity storage medium and a storage function has been studied. this is,
The broadcast program is stored and stored in a large-capacity storage medium.

However, in this case, if the user wants to know the update of the program contents, the user has to watch the accumulated programs before and after the update and confirm the contents of these programs. . When the program structure is complicated or the number of programs to be recorded increases, it takes a lot of time and effort for the user to actually know the update of the program.

Further, in the program receiving apparatus, the programs to be stored and stored are digital data and are generally composed of a plurality of program configuration data (modules). Then, since a plurality of pieces of program configuration data are acquired and the display screen, sound, etc. of the program are configured by combining these, even if the user knows the name of the updated program configuration data, etc. Since the user did not know which part of the program was updated, there was a problem that the user did not notice the update of the program.

[0007]

As described above, in the conventional program receiving apparatus, the user views the programs before the update and the programs after the update, which are sequentially accumulated, and confirms the contents of these programs. Until then I could not know the update. Then, there is a problem that it takes a lot of time and effort for the user to actually know the update of the program.

Further, in the conventional program receiving apparatus, even if the user knew the updated program, there was a problem that it was not known which part of the program was updated.

As a technique related to the above problem, Japanese Unexamined Patent Publication No. 20
No. 01-197381 has been proposed. This proposal is to store various television programs as well as advertisement information in the storage means of the television apparatus, and the content of the advertisement information is a technology that can be automatically rewritten as appropriate.

However, in this proposal, although the advertisement time limit of the advertisement information is set, the user is not notified that the program that has been stored and accumulated has been updated.

As another technique, Japanese Patent Laid-Open No. 2001-24
No. 5244 has been proposed. The purpose of this proposal is to eliminate recording mistakes in series programs and to enable continuous automatic recording.

However, even in this proposal, the user is not notified that the program already stored and accumulated has been updated.

An object of the present invention is to notify a user that a program that has been stored and accumulated has been updated. Further, if there is further hope, the purpose is to notify the user of which part of the program that has already been stored and accumulated has been updated.
