Abstract

PURPOSE:To improve the handling further by storing reservation commands in turn in a storage device whenever a reservation command is inputted, reading the reservation commands in turn in inputted order and performing a driving control on the information recording and reproducing device. CONSTITUTION:Whenever a reservation command is specifically inputted by operators 5A (command key), 5B (reservation command specifying key) and/or 5C (reservation command selecting key), such reservation commands are stored in turn to the storage device 12 by a control data processing CPU 7. Then, whenever an operation mode based on a reservation command is finished, the reservation commands from the storage device 12 are taken out in inputted order, and a changeover control is performed on the operation mode based on the reservation command. By this method, reproducing processing procedures are inputted more easily.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Use The present invention relates to an information recording and reproducing device, and is suitable for application to, for example, a video tape recorder.

B. Summary of the Invention The present invention provides an information recording/reproducing device in which a reservation command is stored in a storage device each time a reservation command is specified based on an operator, and when canceling an input reservation command, the reservation command is stored at the time of input of the reservation command. By canceling the reservation commands in the reverse order and reading out the reservation commands stored in the storage device in the order in which they were input each time a predetermined operation mode ends and specifying the next operation mode, the input of reservation commands can be made even easier. By displaying the reservation status of the reservation command, management of the reservation status can be made easier.

C. Prior art In conventional consumer video tape recorders, commands are sequentially input in the order of, for example, "playback → rewind → stop" by operating a remote controller or control keys on the video tape recorder body, and the input commands are Even when it is desired to drive and control the operation of a video tape recorder based on the following commands, the video tape recorder can only be driven and controlled based on the last command among the sequentially input commands.

Problems to be Solved by the Invention In order to solve this problem, conventionally, as shown in FIG. Move the cursor K based on the desired processing procedure (
For example, REW-4EJECT) is specified, but in order to specify and input such a playback processing procedure, display the automatic playback order list (AUTOMENU) on the monitor and enter the desired processing procedure from the screen. There is a problem in that it takes time and effort to input the playback processing procedure because it has to be searched and specified.

In addition, in order to simplify such input operations, rPLA is installed on the video tape recorder body or remote control controller.
It is conceivable to arrange operation keys such as Y-+REW→5TOPJ, but in this case there is a problem that the number of operation keys increases and the operation of the remote controller etc. by the user becomes even more complicated.

The present invention has been made in consideration of the above points, and an object thereof is to propose an information recording/reproducing apparatus in which a reproduction processing procedure can be input more easily.

Means for Solving Elia In order to solve this problem, in a first invention, in an information recording and reproducing apparatus that controls switching of operation modes in response to operations of operators 5A, 5B and/or 5C,
, 5B and/or 50 sequentially store the reservation commands in the storage device 12 each time a reservation command is designated and input, and retrieve the reservation commands from the storage device 12 in the order in which they were input each time the operation mode based on the reservation command ends. ,
The operation mode is switched and controlled based on the reservation command.

Further, in the second invention, when canceling the reservation commands stored in the storage device 12, the information recording/reproducing device 1 cancels the reservation commands in the reverse order from when they were input.

Furthermore, in the third invention, the information recording/reproducing device 1 displays the reservation status based on the reservation command stored in the storage device 12.

F action In the first and second inventions, each time a reservation command is input based on the operators 5A, 5B, and/or 5C, the reservation command corresponding to the operators 5A, 5B, and/or 5C is stored in the storage device 12. However, when the contents of the input reservation commands are desired to be changed, the reservation commands are canceled in the reverse order of input, thereby making it possible to obtain an information recording and reproducing device that makes it easier to input and change the reservation commands than before.

Furthermore, in the third invention, the reservation status based on the reservation commands stored in the storage device 12 can be visually confirmed on the display screen 4A, thereby making it possible to further facilitate the management of reservation commands.

G example An embodiment of the present invention will be described in detail below with reference to the drawings.

In FIG. 1, a video tape recorder 1 has a control data processing section 2 and a video tape recorder main body 3, and drives and controls the video tape recorder main body 3 and a monitor 4 based on device signals constituted by the control data processing section 2. It is done like this.

Here, the control data processing unit 2 receives input information S1 from the remote control controller 5 via the remote control receiver 6 (a central processing unit for processing control data).
When the data is taken into the CPU 7, it is sent to the bus 8 as control information S2, thereby controlling the circuit elements constituting the video tape recorder main body 3 and the monitor 4.

As shown in FIG. 2, the remote control device 5 has a
Command keys 5A for "play", "fast forward", "rewind", etc., reserved command designation key (STORE) 5
B and a reserved command erase key (CANCf!L) 5C.

Reserved command designation key 5B is for control data processing CPU 7
In contrast, the command information of the command key 5A operated after the reserved command designation key 5B is controlled to be stored in the memory 12 in a first-in first-out (FIFO) manner, and the reserved command deletion key 5C is designed to cancel the last command among the commands recorded in the memory 12 for the control data processing CPU 7.

Further, the control data processing CPU 7 communicates control information S3 with the mechanism control central processing unit (CPU) 10 of the video tape recorder main body 3 via the bus 9, thereby controlling the mechanism elements constituting the video tape recorder main body 3. It is adapted to generate a control signal S4.

The keyboard 11 is configured to input an input information signal S5 to the control data processing CPU 7.
The PU 7 is configured to store the commands input as the input information signal S5 or the input information S1 in the memory 12 via the bus 8 in the designated order.

When it is necessary to inform the user of the processing results obtained by processing data in the control data processing CPU 7 in this way, the control data processing CPU 7 uses the display control unit 13 as part of the control information S2.
a superimpose output signal S that supplies an image display information signal S6 to the image display information signal S6 and superimposes a video based on the image display information signal S6 on the display screen 4A of the monitor 4;
7 is supplied to the monitor 4, and images showing the operating status and reservation status of currently executed commands and reserved commands are displayed on the display screen 4A, so that the user can confirm the reservation status. .

In the above configuration, when the user wants to continuously drive and control the video tape recorder 1 by specifying a plurality of commands in advance, for example, after rewinding the video tape currently stored in the video tape recorder main body 3, When the tape is to be played back from the beginning, and once it has been played to the end, it is to be rewound again and ejected to the outside, a reservation command is input based on the command key 5A and reservation command designation key 5B of the remote controller 5.

That is, as shown in FIG. 3, when the user presses the rewind key "Kuku" as the command key 5A of the remote control controller 5, the remote control receiver 6 receives such information as input information S1, and controls this information. The data is supplied to the data processing CPU 7.

The control data processing CPU 7 supplies control information S3 to the mechanism control CPU 10 via the bus 9 to instruct rewinding of the videotape, and also displays the current status of the video tape recorder main body 3 to the display control unit 13 via the bus 8. The operation mode of is specified by the image display information signal S6.

Based on the control information S3 and the image display information signal S6, the mechanism control CPU 10 sends a control signal S4 to drive and control the video tape recorder main body 3 to the rewinding state, and the display control unit 13 controls the display screen of the monitor 4. The current operating mode "<<" is superimposed on the lower left corner of 4A (Fig. 3 (A)).

Incidentally, no command is input to the FIFO memory 12 at this time.

Next, when the user inputs an operation command after rewinding the videotape by pressing the reservation command designation key 5B, that is, the rSTORE J key, and then specifying the playback key ">", the control data processing CPU 7 inputs the reservation command. is stored at the top of the memory via the bus 8, and the reservation command is displayed via the display signal processing section 13 in the lower left corner of the display screen 4A of the monitor 4, followed by the current operating mode. do.

Furthermore, the user sequentially presses the rsTORE J key 5 in the same manner.
After pressing B, press rewind key r<I<IJ 5A,
When the rsTORE J key 5B is subsequently pressed and the ejection key rEJEcT J 5A is pressed, the control data processing CPU 7 converts the input information S1 input from the remote control controller 5 into the output data shown in FIGS. 3(C) and (D). As shown in FIG. (D)) is displayed.

After inputting the reserved command, the control data processing C
When the PU 7 detects the completion of rewinding the videotape as control information S3 from the mechanism control CPU 10 via the bus 9, it retrieves the reservation commands stored in the memory 12 via the bus 8 in the order in which they were input ( Fourth
Figure (A)).

When the control data processing CPU 7 reads out that a playback command is stored as a reserved command after the end of rewinding, it sends a playback operation instruction as control information S3 to the mechanism control CPU10, and also sends an image to the display control unit 13. The current operating mode and reserved command information are indicated as the display information signal S6.

At this time, when the mechanism control CPU 10 inputs a reproduction command based on the control information S3, it sends out a control signal S4.
The video tape recorder main body 3 is driven and controlled to a video tape playback operation state. At this time, the display control unit 13 displays the current operating mode and reserved command information on the display screen 4A of the monitor 4 as shown in FIG. 4(A).
〈→EJECT Superimpose display of J.

Eventually, when the mechanism control CPU I O detects that the video tape has finished playing back and entered the finished state, it sends control information S3 to the control data processing CPU 7.

After that, the control data processing CPU 7 reads out the video tape rewind command as a reservation command stored in the memory 12, and controls the video tape recorder main body 3 to rewind via the mechanism control CPU 10, and also controls the monitor 4. The current operating mode and reserved command information "Kuku→EJECT J" are displayed on the display screen 4A (FIG. 4(B)).

Similarly, when the control data processing CPU 7 detects the stop of the rewinding operation from the mechanism control CPU 10, it reads out the "r EJECT" command (FIG. 4(C)) stored in the memory 12, and
The videotape is ejected from the videotape recorder main body via
Displays ICT J and ends the reserved command execution operation.

During the execution of control operations based on such reservation commands, for example, if you wish to cancel or change the reservation command to perform rEJEcT J after rewinding the videotape, write the reservation command "re<" in the memory 12 as shown in FIG. 5(A). →EJEC
With TJ memorized, press the reserved command deletion key (
CANCEL) 5 When C is operated, the last command rEJECT J among the reserved commands stored in the memory 12 is canceled, and only the rewind command "<<" is reserved. control the state in which it is.

This allows the reservation command to be easily changed.

According to the above configuration, by providing the reservation command designation key 5B and the reservation command deletion key 5C, the reservation command can be input more easily than before, and the reservation command can also be changed freely. A video tape recorder that is much easier to use can be obtained.

In the above-mentioned embodiment, the case where the reservation command is rewound, then played, and after the playback is finished, rewound again and is ejected is described, but the present invention is not limited to this. Can be applied.

Further, in the above-described embodiment, a case was described in which a first-in, first-out system memory 12 was used, but instead of this, the present invention may use a normal memory and operate in a manner similar to a first-in, first-out system. .

Further, in the above-described embodiment, a case has been described in which the reservation command is input using the remote controller 5, but in the present invention, the reservation command may be input using the keyboard 11 instead.

Furthermore, in the above embodiment, the display screen 4 of the monitor 4
Although the case has been described in which the current operating state and reserved command are superimposed and displayed on A, the present invention is not limited to this, and may be displayed only when the user wants to check the operating state as specified. .

Further, in the above-described embodiments, a case has been described in which the present invention is applied to a video tape recorder, but the present invention is not limited to this, but can be widely applied to so-called tape cassette recorders with radios.

Furthermore, in the above-described embodiment, when canceling reserved commands, the r CANCEL J key is used to cancel the reserved commands sequentially from the end, but in the present invention, instead of this, the reserved commands are canceled all at once using the stop key. You may also cancel it.

H Effects of the Invention As described above, according to the present invention, each time a user inputs a desired reservation command, the reservation commands are sequentially stored in the storage device, and the reservation commands are sequentially stored in the storage device in the order in which they are input. By controlling the reading and driving of the information recording and reproducing device, it is possible to obtain an information recording and reproducing device that is much more convenient to use.

In addition, the reservation status of the reservation commands stored in the storage device is displayed on the display screen, and when canceling a reservation command, the reservation commands are deleted in the reverse order in which they were entered, allowing the user to easily make reservations.
