If there is no program reservation by the user, the broadcast contents are classified as they are.

At step SP5, if the category area is selected and the broadcasting station is designated, the category code is detected and stored. In step SP6, a FIFO operation is performed in which old broadcast contents are sequentially erased and new broadcast contents are recorded. At step SP7, the remaining capacity of the memory capacity assigned to the category area is checked.

If the recording capacity of the category area has a margin, the process proceeds to step SP8. If the recording capacity does not have a margin, the process returns to step SP6 to repeat the FIFO operation to update the broadcast content. In step SP8, the ID code such as the broadcast time is checked, and if the ID codes match, the process proceeds to step SP9 to continue recording, and if they do not match, the process returns to step SP8 again to operate to match the broadcast times. . At step SP10, the series of recording mode operations ends.

Next, the operation in the reproduction mode will be described with reference to FIG. When the user selects and starts the reproduction mode (step SP11), in step SP12, the menu screen showing each category area shown as an example in FIG. 2B is displayed based on the control program in the ROM / RAM. In step SP13, a desired category is selected (recorded broadcast content) from the menu screen, and if NO, the process returns to step SP12 and Y
If ES, proceed to step SP14. Step SP1
