[0022]
In the present invention, the setting of a recording reservation, also referred to as an answering machine, is performed as follows. The present invention is intended to easily set a reservation for the next broadcast of the currently viewed program which is selected by the viewing-only tuner 3 or the recording-only tuner 5 and displayed on the display unit 12. .
[0023]
When the key input unit 8 is a remote control transmitter, the key input unit 8 is configured as shown in FIG. The key input unit 8, which is a remote control transmitter, includes numeric keys 81, a reservation key 82, and a standard / 3 times switching key 83 in a matrix.
[0024]
The key input control unit 9 determines whether or not the reservation key 82 of the key input unit 8 has been pressed in step S1 of FIG. 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 reads the current time and the day of the week from the clock control unit 16 in step S2 in FIG. The recording time frame selection unit 19 sets the recording time frame according to the read current time in step S3 in FIG.
[0025]
Here, the recording time frame set by the recording time frame selection unit 19 will be described. The recording time frame selection unit 19 has a recording time frame setting table as shown in FIG. 5 as an example. In the recording time frame setting table shown in FIG. 5, recording time frames of recording time 1 to recording time 4 are respectively set according to the current time. In 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. Note that the current time in the recording time frame setting table is a time excluding minutes, and it is assumed that the current time is 20:00 at 20:10, 20:30, or 20:45.
[0026]
For example, assuming that the current time read from the clock control unit 16 is 20:30, the recording time frame selection unit 19 sets the highest priority recording time 1 in the current time 20:00 column in the recording time frame setting table. Is selected from 20:00 to 21:00.
As shown in FIG. 5, the recording time frame set in the recording time frame setting table is based on one time frame, first half 30 minute frame, second half 30 minute frame, and two time frame. Become For example, in the 20:00 hours, since there are few programs in 30-minute intervals, 20: 00-21: 00 is the highest priority recording time 1, and the second highest priority recording time 2 is , 19:00 to 21:00 is a recording time frame.
[0027]
The channel to be recorded is the program currently being viewed on the display unit 12. The information of the channel is also input to the recording time frame selection unit 19 from the key input control unit 9, and the preset standard / 3 times Since the recording mode information is also input from the key input control unit 9, the recording time frame selection unit 19 inputs the information of the channel and the recording mode and the recording time frame set as described above to the timer setting unit 17. The timer setting unit 17 inputs these pieces of information to the on-screen display control unit 20. 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 in step S4 of FIG. FIG. 6 shows an example of the on-screen display.
[0028]
Next, in step S5 of FIG. 2, the key input control unit 9 determines whether or not a time change key (here, the number key 2) for changing the recording time frame in the key input unit 8 has been pressed. to decide. When the time 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, and returns to step S4. Therefore, when the recording time frame is changed, the recording start time and the recording time surrounded by the broken line indicated by (1) in the on-screen display shown in FIG. 6 are changed. Although not shown in FIG. 2, when the standard / 3x 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 indicated by (2) is set. Be changed.
[0029]
Further, the key input control section 9 determines whether or not the recording day change key (here, the numeral key 3) for changing the recording day in the key input section 8 has been pressed in step S7 of FIG. I do. When the recording day change key “3” is pressed, the output of the key input control section 9 is input to the recording day selection section 21. The recording day selection section 21 is for selecting a recording day on which a recording reservation is set. The recording day selection unit 21 changes the recording day of the program to be recorded in step S8 of FIG. 2 and inputs the recording day selected by the change to the timer setting unit 17. Note that the recording day is, for example, "once a week", "every week", "every day", "every Monday to Saturday", "every Monday to Friday", "every Monday to Thursday", and the like.
[0030]
The timer setting unit 17 inputs the information of the recording day change to the on-screen display control unit 20. Therefore, the on-screen display control unit 20 changes and displays the reservation setting screen in step S9 in FIG. Alternatively, another new reservation setting screen may be displayed. In the present embodiment, when the reservation setting screen is displayed on-screen in step S4 of FIG. 2, first, as shown by the dashed line indicated by (3) in FIG. Is displayed as Therefore, when the recording day is changed, the part of the recording day is changed to another recording day. Incidentally, (1), (2), and (3) shown in FIG. 6 are not displayed on the screen but are added for convenience.
[0031]
Here, the operation of the recording day selection unit 21 in FIG. 1 and a more desirable configuration when shifting from step S7 surrounded by a broken line in FIG. 2 to step S8 will be described with reference to FIGS.
[0032]
The recording day selection unit 21 includes a recording day selection table as shown in FIG. In the recording day selection table, as shown in FIG. 7, the recording day selection mode includes “once (for the next week)”, “every week”, “Monday to Saturday”, “Monday to Friday”, and “Monday to Thursday”. , "And" every day ", and codes 0 to 5 are assigned to each. Further, corresponding thereto, the day-of-the-week selection information is set for each current day of the week for which a reservation has been set, as to whether or not the recording day can be selected. In FIG. 7, "“ "means selectable (no skip), and"-"means not selectable (skip).
[0033]
As shown in FIG. 3, when the recording day selection key "3" is pressed in step S7, the recording day selection unit 21 increments the day selection code in step S71 and switches the day selection code. At this time, it is determined whether or not the day of the week selection code is 6 or more in step S72. If the day of the week selection code is 6 or more, the day of the week selection code is set to 0 in step S73. As a result, if the recording day change key "3" is pressed when the day selection code is "5", which is "every day", it returns to "0" of "once". If the day of the week selection code is not 6 or more, the process proceeds to step S74.
[0034]
Since the current day of the week from the clock control unit 16 is input to the recording day of the week selection unit 21, in step S74 of FIG. 3, the day of the week is selected from the recording day of the week selection table shown in FIG. Read information. Then, in a step S75, it is determined whether or not the day of the week selection code selected in the step S74 can be selected on the current day of the week (whether or not to skip).
[0035]
For example, in FIG. 7, if the current day of the week is Saturday and the day of the week selection mode is "Monday to Saturday" (day of the week selection code is 2), skipping is not possible and selection is possible. If the current day of the week is Saturday and the day of the week selection mode is "Monday to Friday" (day of the week selection code is 3) or "Monday to Thursday" (day of the week selection code is 4), these recording days of the week cannot be selected. It becomes possible.
As described above, if the skip is not performed in step S75, the process directly proceeds to step S8 to change the recording day. If skipping, the process returns to step S71 to switch to the next recording day.
[0036]
As described above, in the present embodiment, the selectable recording day is set according to the current day, so that, for example, the current day is Saturday and it is originally desired to select “Monday to Saturday”. Regardless, it is possible to avoid a problem that “Monday to Friday” or “Monday to Thursday” is selected by mistake. Therefore, the viewer can reliably set the desired recording reservation, and does not set an incorrect recording reservation.
[0037]
On the other hand, returning to FIG. 2 again, there is no problem with the contents of the reservation setting screen initially displayed on-screen, and the time change key “2” is not pressed in step S5 of FIG. If 3 "has not been pressed, the key input control unit 9 determines whether or not the registration key (here, the numeral key 1) has been pressed in step S10 of FIG. 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 in step S11 in FIG. FIG. 6 also shows an example of the on-screen display after the registration key “1” is pressed. Then, in step S12 of FIG. 2, the on-screen display control unit 20 deletes the reservation setting screen, and returns to step S1.
[0038]
If the registration key "1" is not pressed in step S10 of FIG. 2, the timer setting unit 17 waits for a predetermined time, for example, 5 seconds, from the display of the reservation setting screen in step S13 of FIG. In step S12 of FIG. 2, the reservation setting screen is deleted, and the process returns to step S1.
As a result, the recording reservation mode is released, and the apparatus waits for the reservation key 82 to be newly pressed.
[0039]
Then, similarly to the related art, the timer control unit 18 compares the day of the week and the current time from the clock control unit 16 with the recording reservation information input from the timer setting unit 17. Then, the timer control unit 18 controls to switch the recording dedicated tuner 5 to the channel for recording before a predetermined time, for example, 20 seconds before they match, and also controls to switch the VTR unit 10 to the recording start preparation state. The timer control unit 18 controls the VTR unit 10 to start recording at the recording start time and end recording at the recording end time.
[0040]
The key input control unit 9, clock control unit 16, timer setting unit 17, timer control unit 18, recording time frame selection unit 19, on-screen display control unit 20, and recording day selection unit 21 in FIG. It can be constituted by a microcomputer.
Furthermore, in the present embodiment, a double tuner television receiver equipped with two tuners, ie, a viewing-only tuner 3 and a recording-only tuner 5, has been described. However, a television receiver with one tuner may be used. .
