Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reservation system in a recording / recording apparatus having a timer function for counting time and having a reservation function capable of making a recording / recording reservation at this time.

[0002]

2. Description of the Related Art A conventional example will be described by taking a video tape recorder (hereinafter simply referred to as a VTR device) as an image recording / sound recording device.

Generally, a VTR device is a TV as a function.
It has a recording function, a VTR tape reproducing function, and a clock function, thereby having a reservation function for a plurality of recordings.

FIG. 5 is a block diagram showing an example of a VTR device. Conventionally, as shown in FIG. 5, a VTR device receives a timer synthesizer 34 for receiving a reservation signal from a remote controller 30 and receiving a channel selection instruction signal from the timer microcomputer 34 by receiving the reservation signal from the remote controller 30, and a frequency synthesizer.

And a controller 39. Further, the timer microcomputer 34 is a head /
The fact that the mechanical section is in the recording state (hereinafter, such mechanical state change is referred to as function change) is input from the system control microcomputer 35 and displayed on the screen display 36.

FIG. 6 is a block diagram showing the configuration of the timer microcomputer shown in FIG. As shown in FIG. 6, the timer microcomputer 34 includes a CPU 41, which is a central processing unit, and a CPU 41.
RO that stores a program that performs processing centered on PU1
An M42, a RAM 43 for storing the recording reservation contents and the VTR function state, an I / O port 45 for inputting / outputting remote control signals and peripheral devices, a clock timer 44 for counting time, a system controller, A serial interface 46 for inputting / outputting data to / from the tuner is provided.

The recording reservation function of the conventional VTR device has a reservation number of 8 reservations, a reservation range of 1 year, and a reservation source of TV / CA.
It is complicated with TV / BS. Here, in order to simplify the description, the description will be given using a recording reservation function in which the number of reservations is 2, the reservation range is 24 hours, and the reservation source is limited to the TV. The information for reservation includes a start time, an end time, and a recording channel, and these pieces of information are set by the operator using the remote controller and then transmitted to the timer microcomputer by the reservation key of the remote controller. Also, the keys that can be operated by the remote control are limited to the above-mentioned reservation keys, channel keys for direct channel selection, and function keys for recording, playing, and stopping.

FIG. 7 is a flow chart for explaining an example of a conventional recording process. Next, the recording process of the VTR device will be described. The current time is now 9:50
Consider a case in which it is already set to AM, there is no recording reservation, and no recording is performed. First, in step A of FIG.
That is, the timepiece is moved by counting the timepiece timer 44 shown in FIG. Next, in step K in step B, the current time is compared with the reservation time. Here, as described above, since there is no reservation, the process proceeds to step C and remote control transmission is input. Here, when the reservation information is transmitted from the remote controller to which the reservation information has been set by the operator, the reservation key is judged in step D, and step J
Go to reservation process. When the TV channel key is transmitted, the channel selection processing is performed in step E, and when the function key is transmitted, the output processing to the syscon is performed in step I. After each processing, in step F, input processing from the syscon is performed and the state of the function is input. In step G, if there is a change from the previous function state, the process proceeds to step H and the function state is displayed.

When the current time and the start time of the reservation coincide with each other in step K of step B, the recording execution process is performed in step L of step B, and similarly, the current time and the end of the reservation are completed in step K. When the times match, a recording stop process is performed in step M.

FIG. 8 is a flow chart for explaining an example of a conventional reservation system, and FIG. 9 is a view showing a display for explanation. Next, the content of the conventional reservation system in step J will be further described with reference to FIG. 8 using a specific example. First, the recording reservation information transmitted by the remote controller is stored in the RAM 43 shown in FIG. Next, it is confirmed in step A whether or not there is a free reserved area to be saved.
Since there is no reservation now, there is space and step B
Go to and store the start time, end time, and recording channel in the reserved area. Next, the reservation content stored in step C is displayed on the screen to notify the operator. FIG. 9A shows a display example when the start time is 10:00 AM, the end time is 11:00 AM, and the recording channel 6 is reserved.

Next, when the current time becomes 10:00 AM, the start time of reservation 1 coincides with the current time in step A of FIG. 5, and recording of channel 6 is started. However,
At 10:30 AM, the start time of reservation 2 matches the current time, so reservation 2 is executed and recording on channel 10 is started. Next time the current time is 11:00 AM,
Since the current time and the end time in step A match, recording is stopped in step M. In this example, 10: 0
6 channels from 0AM to 10:30 AM, 10: 3
10 channels are recorded from 0AM to 11:00 AM, and are not recorded from 11:00 AM to 11:30 AM.

FIG. 10 is a flow chart for explaining another example of the conventional reservation system. If step B, which is the reservation execution process of FIG. 7, is the processing procedure of FIG. 9, first, when the current time becomes 10:00 AM, the start time of reservation 1 and the current time match, and recording of channel 6 is started. It Next, at step A, recording proceeds at 10:30 A.
Even if M is set, the recording of the reservation 2 is suspended, and the recording of the 6th channel of the reservation 1 is continued. The current time is 11:00 AM
Then, in step C, the end times match, and the process proceeds to step D. In step D, it is checked whether or not there is a reservation during the execution time. Since the reservation 2 is during the execution time, the execution of the reservation 2 is started in step E. The current time is 11:30 AM
, The current time matches in step C, and step D
In step F, recording is stopped because there are no more reservations during the execution time.

In this example, from 10:00 AM to 11:00
Reservation 1 is executed until 0 AM and 6 channels are recorded,
From 11:00 AM to 11:30 AM, reservation 2 is executed and 10 channels are recorded. Thus, the conventional V
In the TR device, when the recording reservations are duplicated, the priority order and the recording execution status depend on the processing of the system, and differ depending on the manufacturer and the model. The operator has no choice but to understand these rules from the manual or the execution state, and it is expected that the recording will fail due to an operation error or lack of understanding.

[0013]

As described above, in the recording and recording in the conventional recording / recording device, when there are duplicate recording reservations, the priority order and the execution status depend on the processing of the system. It is difficult for the operator to understand,
It often fails and has the drawback of not knowing at the time of booking. For this reason, recording or a recording error is likely to occur, and since the execution status is unknown, the tape remaining amount may be incorrect and the tape may be broken during the execution.

An object of the present invention is to provide a reservation system for a recording / recording apparatus in which recording / recording is surely executed without failing to record / record due to an operation error or failure of recording / recording due to insufficient remaining tape. Is to provide.

[0015]

According to a first aspect of the present invention, there is provided a reservation system in a recording / recording apparatus, comprising a step of making a plurality of recordings or recording reservations by using a time counted by a clock timer, and the reservation is made. A step of determining whether or not the contents overlap, a step of determining the priority of the reserved contents that overlap, a step of calculating a time for recording / recording the reserved contents, and a remaining tape amount according to the calculated time. And a step of outputting and displaying the time schedule of the reservation contents and the remaining tape amount when the reservation execution state is reserved.

Further, in addition to the reservation system in the first recording / recording device, the reservation system in the second recording / recording device is used when a tape shortage occurs in the staple for calculating the remaining tape amount according to the recording time. The step of varying the speed of the tape is included.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a flow chart for explaining an embodiment of a reservation system in a recording / sound recording device of the present invention. This reservation system is a modification of the reservation processing steps described with reference to FIG. 5, that is, the flowchart of FIG.

That is, first, in step A, it is confirmed whether or not there is a free reserved area to be saved. Since there is no reservation now, there is a vacancy and the process proceeds to step B. In step B, the start time, end time, and recording channel are stored in the reserved area. Next, it is checked whether the reservation stored in step C overlaps with other reservations. Now, since the reservation is only reservation 1, there is no overlap and the process proceeds to step J. In step J, the recording time is calculated.

For example, when a reservation is made for the start time 10:00 AM, the end time 11:00 AM, and the recording channel 6,
It is calculated that it is one hour from 10:00 AM to 11:00 AM and is stored in the RAM 43 of FIG. Then, in step F, the remaining amount of the tape currently set is input from the system controller 35 in FIG. Next, the reservation execution content is displayed in step G, and the remaining amount is displayed in step H.

FIG. 2 is a diagram showing a time chart for explaining the recording reservation. The point of the present invention here is to clearly indicate whether or not there is a remaining amount necessary to execute the reservation. For example, as an example, when the remaining amount input in step F is 1 hour and 15 minutes, there is a sufficient remaining amount for reservation of the recording time of 1 hour calculated in step J, and therefore, FIG.
It becomes a solid line display like. If the remaining amount input in step F is 45 minutes, there is no remaining 15 minutes, and the tape lacks as shown in FIG. 2B.
In this way, the execution time is pre-calculated at the time of reservation, and the state of the remaining tape amount is indicated to the operator by using the display means or the like.

Next, the second reservation (start time 10:30
AM, end time 11:30 AM, recording channel 10)
I will explain the procedure when I reserved. First, in step B, the reservation content is stored in the reservation 2. Next, in step C, when checking for reservation duplication, 10:30 AM to 11:00 AM
It can be seen that the reservations for 30 minutes overlap until. Therefore, the process proceeds to step D, and the priority order of reservation is determined. If the reservation execution process is execution of reservation 1 from 10:00 AM to 10:30 AM and reservation 2 from 10:30 AM to 11:00 AM, the continuous recording time is calculated as 1 hour in step E. Next, in step F, the remaining amount of the tape currently set is input from Syscon. Then, the execution contents of the reservation are displayed in step G, and the remaining amount is displayed in step H.

As a second point of the present invention, when there is such a duplication of reservations, the priority order at the time of execution and the total recording time are clearly shown to the operator using a display means or the like. FIG. 2C shows a display example when the remaining tape amount is 1 hour and 15 minutes. Here, the portion where the reservation is executed is shown by a solid line, and the portion where the reservation is not executed is shown by a dotted line.

In the case where the reservation execution process is as shown in FIG. 2D, reservation execution is executed from 10:00 AM to 11:00 AM and 11:00 AM to 11:30 A.
Reservation 2 is executed up to M. However, the remaining amount of tape is 1 hour and 15 minutes, and it is from 10:00 AM to 11:15 AM, and it is clear from the display that there is no tape for the remaining 15 minutes. Further, if a reservation confirmation key is provided as an effective key, and when the tape is exchanged and the reservation confirmation key is pressed, the processing after step C of FIG. 1 is performed so that the remaining amount can be confirmed after the tape exchange.

FIG. 3 is a flow chart for explaining another recording process in the recording / recording apparatus of the present invention. Next, another embodiment in which the present invention is applied to a VTR device having a function of setting a tape speed at the time of reservation will be described. With a conventional VTR timer that can set the tape speed, standard speed, triple speed, and auto speed can be selected. In the standard case, the recording speed is set to 3 times, and the recording is executed at the reserved recording speed. In the case of auto, the tape speed is adjusted according to the remaining tape amount. For example, if you reserve a recording time of 1 hour and 5 minutes for a tape with a standard remaining capacity of 1 hour, it will record 57 minutes at standard speed, 3 minutes remaining at triple speed, and run out. Is to prevent.

In the reservation system in this embodiment, it is checked in step A whether or not recording is in progress. If not in recording, the current time is compared with the reserved time in step. When it coincides with the recording start time, the process proceeds to step C to execute the recording execution process including the setting of the recording speed. Also, step B
If recording is in progress, the process proceeds to step D to check whether the current recording speed is standard. If it is not standard, it can be removed as it is. If standard recording is in progress, in step E it is checked whether the speed reservation setting is auto. If it's not automatic, you can go through without doing anything.

Next, in the auto mode, the tape remaining amount and the remaining recording time are calculated in step F. If the result of the calculation of step F is insufficient in step G, step H
Outputs an instruction to switch the speed to 3 times to the syscon.

As described in the related art, the processes of steps C to F in FIG. 8 and steps I to K are performed as described below.

FIG. 4 is a flow chart for explaining the reservation system in the recording process in FIG.
The reservation system in the VTR device having the recording process as described above is performed after step F of FIG.
Then, the remaining amount comparison processing when the reservation speed is adjusted is performed. The calculation method in step K is the same as the calculation procedure in execution in FIG. 3, which is calculated in advance at the time of reservation and displayed in step H as the remaining amount display.

[0030]

As described above, according to the present invention, there is a step of calculating and clarifying at the time of reservation setting whether or not there is a tape remaining amount necessary for executing recording / recording reservation, and whether or not there is a duplication of reservation. By making a judgment step and a step of calculating and displaying the total recording time according to the determined priority, it is possible to easily grasp the reservation status of the priority order and execution status of the duplicate reservation depending on the processing of the system. This is effective in preventing a tape recording error during recording or a tape break during execution due to an error in the remaining tape amount.
