Description

[Detailed description of the invention] [Industrial application field] This invention applies to audio and
The present invention relates to a timer reservation device suitable for application to a video device, and more particularly to a timer reservation device which can be effectively used for reservation recording of a TV broadcast program and the like, and can effectively prevent forgetting of reservation.

2. Description of the Related Art Conventionally, a timer reservation device for controlling reservation recording of a television broadcast program or the like is built in a video tape recorder or the like. FIG. 4 is a schematic configuration diagram of a video tape recorder VTR incorporating a timer reservation device.

The timer reservation device T includes a timer control unit 3, a display unit 4, and an alarm unit 5. Timer reservation data such as a start time, an end time, and a broadcast channel of a program to be reserved are controlled by the system control computer 1. Is input from the keyboard 2 to the timer control unit 3 and is displayed on the display unit 4.

If an error or omission in timer reservation data is input from the keyboard 2, an incorrect operation such as forgetting to attach the magnetic tape 20 or attaching the magnetic tape 20 with the erroneous erasure prevention claw broken will occur on the keyboard 2. When the provided reservation standby key is turned on, it is notified by an alarm sound or blinking display, respectively.

When you turn on the reservation standby key and enter the reservation standby mode,
The start time of the reserved program is monitored by the timer control unit 3.

At the start time of the reserved program, the apparatus power is turned on under the control of the system control computer 1, and the capstan motor 10, the reel motor 11 and the drum motor 12 are turned on.
Are controlled via the servo circuit 6. At the same time, the video signal and the audio signal supplied from the tuner unit 8 are supplied to a video head (four-head configuration in this example) 13 and an audio head 14 via the video / audio circuit 7. Further, an erasing signal is supplied from the video / audio circuit to the erasing head 15, and recording is started.

Next, at the end time of the reserved program, the recording on the magnetic tape 20 is terminated, the power is turned off, and the mode returns to the reservation standby mode.

FIG. 5 shows the video tape recorder VT shown in FIG.
FIG. 9 is a diagram showing transition of an operation mode of R.

The video tape recorder VTR shifts from a power-off state M0 to a power-on state M1 by turning on a power key. Subsequently, after setting of a magnetic tape, a broadcast channel, etc., if the recording / playback key is turned on, the mode shifts to a manual recording / reproducing mode M5.

On the other hand, in order to perform the scheduled recording from the power-on mode M1, the user first turns on the reservation key and shifts to the program reservation mode M2.
Then, timer reservation data such as a broadcast start time (year, month, day, day of the week, time), a broadcast end time, and a broadcast channel are input using the keyboard 2. An error or omission in timer reservation data is notified by an alarm sound or blinking display of the input data.

After the input of the timer reservation data is completed, the reservation key is turned off to return to the power-on mode M1, the magnetic tape 20 is mounted, and the reservation standby key is turned on to shift to the reservation standby mode M3. Here, when the magnetic tape 20 is not mounted, or when the magnetic tape 20 with the erroneous erasure preventing claw is broken is mounted, a warning is issued by an alarm sound or the like.

Reservation data is set correctly, and reservation standby mode M3
When the scheduled program's start time arrives during standby at, the scheduled recording mode M4 is entered, recording of the reserved program is started automatically, and when the scheduled program end time is reached, recording ends and the program enters the reserved standby mode M3. Return automatically.

The transition from the reservation standby mode M3 to the power-on mode M1, the transition from the manual recording / reproducing mode M5 to the power-on mode M1, and the transition from the power-on mode M1 to the power-off mode M0 can be performed by reversing the above operation. The description thereof is omitted.

[Problems to be Solved by the Invention] With the recent diversification of lifestyles and the start of 24-hour broadcasting, the above-mentioned reserved recording mode M4 has been frequently used. In addition, the function of the timer reservation device T as described above has also been enhanced, and it has become possible to reserve programs even several months to one year in advance.

For this reason, in spite of the fact that a program reservation is set, there is a case where it is desired to record another program on the way. In such a case, it is necessary to temporarily cancel the reservation standby mode M3. Then, after recording the desired program, the reservation standby key must be turned on again to return to the reservation standby mode M3.

After setting a program reservation, a recorded program may be reproduced. In such a case, reservation standby mode
It is necessary to temporarily release M3, and after reproducing a desired program, the reservation standby key must be turned on again to return to the reservation standby mode M3.

However, the conventional reservation timer does not have an alarm for such a case.
In many cases, the scheduled recording fails because the M1 remains or the power-off mode is set to M0.

Therefore, an object of the present invention is to provide a timer reservation device that can effectively prevent the failure of scheduled recording frequently occurring when the above-described conventional timer is used.

[Means for Solving the Problems] In order to solve the above-mentioned problems, in the present invention, at least one of the current time and the start time of the reserved program is displayed, and a display indicating that the program is waiting for reservation is displayed. A timer reservation device comprising: a reservation program setting unit; a reservation program setting unit; and a reservation standby mode setting unit. A discriminating means for discriminating the presence or absence of the setting of the reserved program by the program setting means, and a mode discriminating means for discriminating whether or not the reservation standby mode is set by the reservation standby mode setting means, wherein the program setting is performed by the reserved program setting means. When the reservation standby mode is set by the reservation standby mode setting means, the reservation standby mode is canceled and the reservation is made by the discrimination means. When it is discriminated that a program has been set and when it is discriminated that the reservation standby mode has not been set by the mode discriminating means, the start time of the reserved program is blinked on the display unit. is there.

[Operation] According to the configuration of the timer reservation device T according to the present invention, the presence / absence of a reserved program is discriminated by the discrimination means provided in the timer control unit 3, and the reservation is made by the error detection means provided in the timer control unit 3. An error in the program reservation data is detected. Thereafter, when the reserved standby mode M3 is not set in spite of the presence of the reserved program, the start time of the reserved program is blinked and an alarm is sounded. The blinking display and the alarm prevent the user from forgetting to return to the reservation standby mode M3.

[Embodiment] Next, a case where the timer reservation device according to the present invention is applied to a video tape recorder will be described in detail with reference to the drawings.

Incidentally, the schematic configuration diagram and operation mode transition diagram of the video tape recorder VTR incorporating the timer reservation device T are as follows.
Since it is common to the conventional example shown in FIGS. 4 and 5,
A duplicate description thereof will be omitted.

The timer reservation device according to the present invention includes a display unit 4 for displaying one of a current time or a start time of a reserved program and a reservation standby state, an alarm unit 5 for generating an alarm sound to notify an abnormality of the program reservation, and a display unit. A timer reservation unit T including a timer control unit 3 for controlling the unit 4 and the alarm unit 5 includes a discriminating unit for discriminating the presence / absence of a reserved program, and detecting an error such as reservation data or a reservation operation to the alarm unit 5. The timer control unit 3 includes an error detection unit that generates an alarm sound and displays an error on the display unit 4, and a mode discrimination unit that discriminates whether or not the reservation standby mode is set.

As a result, when the reserved standby mode is not set even though there is a reserved program, the start time of the reserved program is blinked on the display unit 4 to prevent forgetting to set. .

Furthermore, the timer control unit 3 is provided with a reservation alarm time setting means for setting an arbitrary designated time prior to the start time of the reservation program as the reservation alarm time, whereby the timer is set to the reservation standby mode despite the presence of the reservation program. If not, the start time of the reserved program is blinked and displayed together with the alarm sound at the designated time, so that forgetting to set can be prevented more reliably.

The above-described operation is specifically executed by a microcomputer of the timer control unit 3 based on a program, for example, and therefore, the operation of the embodiment of the timer reservation device according to the present invention will be described below with reference to a flowchart.

 FIG. 1 is a flowchart showing an example.

The control program according to this flowchart is started (started) when the program reservation is performed and the reservation standby mode is set, and thereafter the reservation standby mode is released.

First, when this control program is started, step
In ST1, the presence or absence of a reserved program is discriminated. If there is no reserved program, the process ends and returns to the main control program.

If there is a reserved program, the timer reservation data such as the relationship between the start time and the end time of the program and the interrelation of the time between programs is checked, and the check on the magnetic tape 20 is performed (step ST2).

If there is an error, a message to that effect is displayed, and an error avoidance operation such as correction of necessary data or replacement of a tape is performed (step ST3).

If there is no error, that is, if there is a correctly reserved program, it is discriminated whether or not it is in the reservation standby mode M3 (step ST4). If the reservation is in the standby state, that is, if the reservation standby mode M3 is set, the program reservation has been correctly performed. In this example, “standby” and “current time” are displayed on the display unit 4 ( Step ST6).

On the other hand, if the user is not waiting for reservation, in other words, if he forgets to set the reservation standby mode M3,
“Standby” is displayed on the display unit 4 and “reserved program start time” is blinked (step ST5). This warns that a transition to the reservation standby mode M3 is necessary. The mode shifts to the reservation standby mode M3 by pressing the reservation standby key.

FIG. 2 is an example of a processing flow when the start time of a reserved program can be displayed simultaneously in addition to the current time.

Steps ST1 to ST4 are common to FIG.
As a result of the mode discrimination in ST4, when the program is in the reservation standby mode, that is, when the reservation standby mode M3 is set, the program has been correctly reserved, and the display section 4 displays “standby” and “current time”. "Start time of reserved program" is displayed (step ST12). On the other hand, when the user is not in the reservation standby mode, that is, when he / she forgets to set the reservation standby mode M3, the display unit 4 displays “standby” and “current time”,
“Reserved program start time” blinks (step ST1
1).

This allows you to make a scheduled recording mode M3
Is warned that it is necessary to press the reservation standby key.

FIG. 3 is a flowchart showing the operation of still another embodiment according to the present invention. Steps ST1 to ST4, ST11 and ST12 are common to FIG.

In steps ST21 and ST22, an arbitrary alarm time prior to the start time of the reserved program is set by the reserved alarm time setting means provided in the timer control unit 3, and the set alarm time is reached (step ST23). Not in reservation standby mode M3 (N in step ST4
In the case of O), an alarm is sounded (step ST24), and the start time of the reserved program is blinked (step ST11).

[Effects of the Invention] As described above, in the timer reservation device according to the invention, the timer control unit discriminates the presence or absence of a reserved program, the error detection unit detects an error in timer reservation data, and the like, and the reservation standby And mode discriminating means for discriminating modes.

According to this, if there is a reserved program when the reserved standby mode is temporarily released, a warning is issued on the display unit so that the operator can determine the reserved program, so that failure of the reserved recording can be prevented.

Further, if the reservation alarm time setting means is provided, a warning can be issued by an alarm sound, so that the failure of the reservation recording can be more reliably prevented.
