In the present invention, the recording reservation, which is also called voice mail, is set as follows. The present invention is selected by the tuner 3 for viewing or the tuner 5 for recording,
This is for easily setting a reservation for the next broadcast portion of the program currently being viewed, which is displayed on the display unit 12. In the present embodiment, when the same program of the next week is reserved for the next broadcast portion, The operation will be described.

When the key input unit 8 is a remote control transmitter, the key input unit 8 is constructed as shown in FIG. The key input unit 8, which is a remote control transmitter, includes a matrix of numeric keys 81,
A reservation key 82 and a standard / three times changeover key 83 are provided.

The key input controller 9 operates in step S1 of FIG.
At, it is determined whether the reservation key 82 in the key input unit 8 has been pressed. When the reservation key 82 is pressed, the output of the key input control unit 9 is input to the clock control unit 16 and the recording time frame selection unit 19. The recording time frame selection unit 19 is shown in FIG.
In step S2, the current time and day of the week (or date) are read from the clock control unit 16. The recording time frame selection unit 19 sets the recording time frame in accordance with the read current time in step S3 of FIG.

Here, the recording time frame set by the recording time frame selecting unit 19 will be described. Recording time frame selection section 19
Has a recording time frame setting table as shown in FIG. 4 as an example. In the recording time frame setting table shown in FIG. 4, recording time frames of recording time 1 to recording time 4 are set according to the current time. Regarding each recording time frame, that is, the recording start time and the recording end time, the recording start time is before the current time and the recording end time is after the current time. The current time in the recording time frame setting table is
It is the time excluding the minutes, and it is assumed that the current time is 20 o'clock at 20:10, 20:30, or 20:45.

For example, if the current time read from the clock control unit 16 is 20:30, the recording time frame selection unit 19 has the highest priority in the column of the current time 20:00 in the recording time frame setting table. Recording time 1 is selected, which is recording time 20:00 to 21:00.
As can be seen from FIG. 4, the recording time frames set in the recording time frame setting table are 1 hour frame, 30 minutes frame in the first half,
The latter half 30 minutes and 2 hours are basically used, and optimization is performed according to the time zone. For example, since there are few programs every 30 minutes at 20:00, recording time 1 with the highest priority is from 20:00 to 21:00, and with recording time 2 having the second highest priority. The recording time frame is from 19:00 to 21:00.

The channel to be recorded is the program currently being viewed on the display unit 12, the channel information is also input to the recording time frame selection unit 19 from the key input control unit 9, and the standard / preset channel is set. Since the information of the triple recording mode is also input from the key input control unit 9, the recording time frame selection unit 1
9 inputs the information of the channel and the recording mode and the recording time frame set as described above to the timer setting section 17. The timer setting unit 17 inputs these pieces of information to the on-screen display control unit 20. In step S4 of FIG. 2, the on-screen display control unit 20 inputs an on-screen signal to the video signal processing circuit 11 to display the reservation setting screen on-screen. An example of the on-screen display is shown in FIG.

Next, in step S5 of FIG. 2, the key input control section 9 determines whether the change key (here, the numeral key 2) for changing the recording time frame in the key input section 8 is pressed. Determine whether When the change key “2” is pressed, in step S6 of FIG. 2, the recording time frame selection unit 19 selects the recording time 2 having the next highest priority,
It returns to step S4. Therefore, when the recording time frame is changed, the recording start time and recording time surrounded by the broken line in the on-screen display shown in FIG. 5 are changed. Although not shown in FIG. 2, when the standard / three times recording mode is changed by the switching key 83 of the key input unit 8, the recording mode (recording speed) surrounded by a broken line is changed.

On the other hand, if there is no problem in the contents of the reservation setting screen that was first displayed on-screen and the change key "2" is not pressed in step S5 of FIG. 2, the key input control unit 9 proceeds to step S7 of FIG. , It is determined whether or not the registration key (here, the numeral key 1) is pressed. When the registration key "1" is pressed, the setting contents of the recording reservation are input from the timer setting unit 17 to the timer control unit 18 and the reservation is set in step S8 of FIG. Note that FIG. 5 also shows an example of the on-screen display after the registration key “1” is pressed. Then, the on-screen display control unit 20 erases the reservation setting screen in step S9 of FIG. 2, and returns to step S1.

If the registration key "1" has not been pressed in step S7 of FIG. 2, the timer setting section 17 displays the reservation setting screen for a predetermined time in step S10 of FIG.
For example, after waiting for 5 seconds, the reservation setting screen is erased in step S9 of FIG. 2 without performing reservation setting, and the process returns to step S1. As a result, the recording reservation mode is released, and the CPU waits for a new reservation key 82 to be pressed.

Then, as in the conventional case, the timer control unit 18
Compares the day of the week (or date) from the clock control unit 16 and the current time with the recording reservation information input from the timer setting unit 17. Then, the timer setting unit 17 controls to switch the recording-dedicated tuner 5 to a channel for recording a predetermined time before they match, for example, 20 seconds before, and also controls the VTR unit 10 to switch to a recording start preparation state. The timer setting unit 17 controls the VTR unit 10 so that the recording starts at the recording start time and ends at the recording end time.

In the above-described embodiment, the operation when the same program of the next week is reserved and set as the next broadcast of the program currently being viewed has been explained, but it is also possible to set it for the next day or every week. The daily settings can be set arbitrarily. Further, the key input control unit 9 and the clock control unit 1 in FIG.
6, the timer setting unit 17, the timer control unit 18, and the on-screen display control unit 20 can be configured by a microcomputer. Furthermore, in the present embodiment, a television receiver having a double tuner equipped with two tuners, that is, a tuner 3 for viewing and a tuner 5 for recording, has been described. .
