In step S101, the microprocessor 11 determines whether the user requests editing based on the channel mapping. If it is determined that there is a mapping editing request, the flow advances to step S102.

In step S102, the microprocessor 11 displays the day of the week through the OSD, and the user selects a specific day of the week through steps S103 and S104, And selects the channels that can be tuned in.

If the TV viewing time zone and the channel group of a specific day are selected through the above process, the selected data is stored in step S105, and it is determined in step S106 whether the user inputs a termination request.

If it is determined in step S106 that the user's end request has not been input, the process returns to step S102 to re-execute the above operation. If it is determined that the end request of the user is input, the process proceeds to step S107, As shown in FIG.
