Next, the EPG module 370 determines whether a rebroadcast schedule of the program selected by the user exists in the EPG information (S420).

At this time, the service provided from the EPG module 370 is provided with the plot of the program, the broadcast time, the remaining time, the next program, other program information.

If there is a schedule of rebroadcast program in the EPG information (S430), the user selects a portion to record the program (S440).

That is, when the user is currently watching the program, and if the front part or the rear part of the program cannot be viewed, only the part which the user did not watch can be recorded.

This may be set at the time of re-broadcast program recording for the part which the user did not watch after the end of the broadcast by remembering which part the user watched or did not watch.

Subsequently, when the user selects the entire recording of the re-broadcast program (S450), the entire re-broadcast program is set, and the processing unit notifies whether to start the re-broadcast, and starts recording (S460).

At this time, if the user does not select the entire recording of the re-broadcast program, the partial recording of the re-broadcast program is set for the part not watched, and when the re-broadcast is broadcast, the processing unit notifies the part that the user did not watch and record. It is made (S451).

On the other hand, if it is determined whether there is a rebroadcast schedule of the program selected by the user (S420), if a rebroadcast program does not exist in the EPG information (430), a rebroadcast recording attempt period is set by the user (S470).

In more detail, since the EPG information is provided at regular intervals, if the EPG information is provided again later when the re-broadcast program is not in the period, the re-broadcast program recording attempt cannot be made by the user. have.

At this time, the recording attempt period is set to a week or a month or the like according to the user's setting, or set a fixed date.

Then, if the EPG information is updated within the trial period set by the user, it is again determined whether the rebroadcast program selected by the user exists (S471).

Subsequently, if there is a rebroadcast program in the updated EPG information (S472), the portion to be recorded of the rebroadcast program already selected by the user is recorded (S450).

That is, the user records according to the full or partial recording selected in the step of setting the rebroadcast program recording in advance, and informs the user of the start of the rebroadcast.

After the EPG information is updated within the attempt period set by the user, if there is no rebroadcast program (S472), it is determined whether the rebroadcast recording attempt period has expired (S473).

In this case, it is determined whether the trial period set by the user has expired.

Subsequently, when the rebroadcast recording attempt period expires (S474), the user is notified of the attempt period expiration (S475).

Therefore, according to the above method, when the program currently being watched is re-broadcasted, recording can be easily performed and the user can be notified that the re-broadcast is broadcasted.
