An example of the recording reservation setting processing method in the case where the start date and time and the end date and time of the program to be reserved for recording are set as the start time and the end time such as every day or every Monday is described below.

FIG. 3 shows an example of a recording reservation setting processing routine performed by the system controller 80 in this case, and FIG. 4 is for explanation thereof.

Here, for simplicity of description, a recording reservation of a program such as a serial drama broadcasted over a plurality of broadcasts is made by one setting, and the start of the program to be reserved and recorded among the reservation setting items is started. The reservation setting in which the date and time and the end date and time are set as the start time and the end time such as every day or every Monday is referred to as weekly recording reservation every day.

In this recording reservation setting processing routine, the recording reservation setting processing is started by the user performing the recording reservation operation on the operation input unit 110. First, in step S1, the system controller 80 sets the operation input unit 11
From 0, the channel of the program to be reserved for recording, the start date and time,
The end date and time and the recording quality are set as R
Import to AM84.

At this time, the setting of the start date and time and the end date and time is
When “daily” or “every Monday” is set, the system controller 80 knows that the reservation setting is a recording reservation every week.

Next, in step S2, the system controller 80 calculates the recordable recording capacity of the hard disks 61 to 63. At this time, if the program reservation has already been made and it is known that the recording medium is to be used, the estimated use amount of the recording medium is calculated from the recording time and the video / audio compression rate, and the recording time is calculated after the scheduled recording date and time. Subtract from the free space of the hard disks 61-63. If there is a record that is known to be erased, such as when the old program is set to be erased in advance, it is added to the hard disk capacity after the scheduled erasure date.

Next, in step S3, the system controller 80 calculates a recording capacity required for recording one broadcast every day every week.

Next, in step S4, the system controller 80 compares the free space of the hard disks 61 to 63 calculated in step S2 with the space for one broadcast calculated in step S3.
The number of broadcasts that can be recorded in 63 is calculated. The last recorded broadcast date and time is specified from the number of recordable broadcasts, the reserved broadcast date and time, and the calendar stored in the ROM 83.

Next, in step S5, the system controller 80 displays the date and time of the last scheduled recording of the program recorded every week specified in step S4.

As described above, the recording reservation of a program such as a serial drama broadcasted over a plurality of broadcasts is made by one setting, and the start date and time and the end date and time of the program to be reserved and recorded among the reservation setting items are set. When setting the start time and the end time such as every day and every Monday, the broadcast date and time recorded last on the recording medium can be specified and displayed.

In the above-described example, the reservation setting process is realized by software. When the reservation setting process is realized by software, the program constituting the software is executed by the recording / reproducing apparatus 10 using a dedicated hardware. When configuring hardware, a system controller 80 which is a computer incorporated therein is used.
