Abstract

PROBLEM TO BE SOLVED: To easily and continuously record input information employing plural recording media. SOLUTION: When the recording of input signals against a first tape is started, a CPU 14 of a controller 11A monitors the remaining time of the tape and the recording of the input signals against a second tape by a device 11B is initiated. When the recording is completed in the controller 11A, a recording operator mounts a third tape on the controller 11A. If the remaining time of the tape in the device 11B becomes less than a prescribed time, the CPU 14 of the controller 11A starts the recording of the input signals against the third tape. Then, the similar operations are repeated. Thus, input signals are continuously recorded on plural tapes while the overlapped period, in which same input signals are recorded on plural tapes in an overlapped manner, is set.

When recording continuously using the device 1A and the device 11B, first, recording of an input signal to a tape is started using either the controller 11A or the device 11B. Here, a description will be given assuming that recording is started from the controller 11A. In this case, as shown in (a), when the CPU 14 of the controller 11A starts recording the input signal to the first tape A, it always monitors the remaining time (recordable time) of the tape A, and the remaining time is a predetermined time. When the time is equal to or less than the time (for example, 2 minutes), as shown in FIG.
Recording of the input signal on the second tape B is started. In the controller 11A, when the tape A reaches the end and the recording is completed, the recording operator takes out the tape A and mounts the third tape C on the controller 11A. When the CPU 14 of the device 11B starts recording the input signal to the tape B, it always monitors the remaining time of the tape B and sends the information to the controller 11A,
When the remaining time of the tape B in the device 11B becomes equal to or less than a predetermined time, the CPU 14 of the controller 11A
As shown in (a), recording of the input signal on the tape C is started. In the device 11B, when the tape B reaches the end and the recording is completed, the recording operator
Is taken out, and the fourth tape D is mounted on the device 11B. When the CPU 14 of the controller 11A starts recording the input signal to the tape C, it always monitors the remaining time of the tape C.
As shown in (b), the tape D by the device 11B
To start recording the input signal to the. Hereinafter, the same operation is automatically repeated.

With the above operation, the input signal recorded in the portion near the end of the tape (for example, the portion for two minutes before the end) is input while the duplication is also recorded in the beginning of the next tape. The signal is continuously recorded on a plurality of tapes. In FIG. 5, reference numeral 21 denotes two tapes A,
B represents the part of the same input signal that is duplicated and recorded in B,
Similarly, reference numeral 22 denotes a part of the same input signal that is recorded in duplicate on the two tapes B and C, and reference numeral 23 denotes 2
The same input signal is recorded on two tapes C and D in an overlapping manner. Hereinafter, the same input signal is 2
A period in which data is recorded on one tape in duplicate is called an overlap period.

In the present embodiment, the time codes are recorded on the tapes such that the same time code for the same input signal recorded on the two tapes in the overlapping period is the same. Therefore, in the present embodiment, the CPU 14 of the controller 11A controls its own time code generator so that each time code of the same input signal recorded on two tapes in the overlapping period is the same. The time code generated by the time code generator 13 of the device 11B is preset based on the time code generated by the time code 13.

[0027] With this, for the same input signal recorded in duplicate on two tapes, the time code is the same in the two tapes, so that the scene recorded over the two tapes can be easily edited. Become. FIG.
FIG. 8 shows an example of editing a scene recorded over two tapes. In the example shown in FIG.
As shown in (b), the input signal 25 at the joint between the temporally continuous scenes (1) and (2) is recorded in a portion near the end of the tape A, and as shown in (b), The same input signal 25 is also recorded at the beginning of the next tape B, and as shown in (c), the signal of scene (1) recorded on tape A and the scene (2) recorded on tape B Is re-recorded on one editing tape so as to be temporally continuous with the signal No. 1. in this case,
Scene overlapped on tape A and tape B (1)
And input signal 25 at the joint of scene (2)
With regard to (2), since the time codes are the same in the two tapes A and B, the editing as shown in (c) can be easily performed.

Next, the operation of the information recording system 10 according to the present embodiment will be described in detail with reference to the flowcharts of FIGS. In this embodiment, when the recording of the input signal to the tape is completed, the controller 11A and the device 11B operate in a manner that the next recording is not performed unless the operation of exchanging the tape is performed (hereinafter, the tape exchange is performed). Mode), and an operation mode (hereinafter, referred to as a repetitive recording mode) in which the input signal is repeatedly recorded on the same tape when the recording of the input signal on the tape is completed. I have. The selection of the two modes is performed by, for example, a predetermined button provided on the operation unit 17.

FIGS. 7 and 8 are flowcharts showing the operation of the information recording system 10 in the tape exchange mode.
In the tape exchange mode, in the controller 11A,
When recording of an input signal is started in response to an operation by the operation unit 17 (step S101), the CPU 14 of the controller 11A monitors the remaining time of the tape. That is, the CPU 14 of the controller 11A determines that the remaining time of the tape in the controller 11A is a predetermined time (eg,
Minutes) or not (step S102). Since the rotation speed of the two reels for winding the tape in the cassette storing the tape changes according to the remaining time of the tape (the remaining amount of the tape), the remaining time of the tape is, for example, 2 It can be obtained from the rotation speed of one reel. If the remaining time is not shorter than the predetermined time (N), the determination in step S102 is repeated. If the remaining time is equal to or less than the predetermined time (Y), the controller 1
The CPU 14 of 1A presets the time code of the device 11B (Step S103). The operation of this preset will be described later in detail with reference to FIG.

Next, the CPU 14 of the controller 11A
Sends a command to the device 11B,
B to start recording the input signal (step S1).
04). Next, the CPU 14 of the controller 11A determines whether the tape in the controller 11A has reached the end and recording has been completed (step S105). If the recording has not been completed (N), the determination in step S105 is repeated. When the recording is completed (Y), the controller 1
The CPU 14 of the 1A is the VTR unit 1 of the controller 11A.
After rewinding the tape by controlling the
The exchange of the tape in A is prompted (step S106).
This is performed by, for example, blinking a lamp associated with a tape eject (eject) button on the operation unit 17. In this case, when the tape eject button is pressed, the lamp is turned off. Next, the CPU 14 of the controller 11A determines whether or not an operation of exchanging a tape has been performed (step S10).
7). This determination can be made, for example, by determining whether the tape eject button on the operation unit 17 has been pressed. If the operation of exchanging the tape has not been performed (N), the determination in step S107 is repeated. When the operation of exchanging the tape is performed (Y), the CPU 14 of the controller 11A determines whether the remaining time of the tape in the device 11B is equal to or less than a predetermined time (step S108). This is, for example, the device 11
B CPU 14 detects the remaining time of the tape in the device 11B, and sends information on the remaining time to the CPU 14 of the controller 11A as needed.
This can be realized by the PU 14 making a determination based on the information on the remaining time. If the remaining time is not shorter than the predetermined time (N), the determination in step S108 is repeated. When the remaining time becomes equal to or shorter than the predetermined time (Y), the CPU 14 of the controller 11A starts recording the input signal in the controller 11A (step S109).

Next, the CPU 14 of the controller 11A
Determines whether the tape in the device 11B has reached the end and has finished recording (step S110). This means that the CPU 14 of the device 11B determines whether the tape in the device 11B has reached the end and the recording has been completed, and sends the information as needed to the CPU 1 of the controller 11A.
4 and the CPU 14 of the controller 11A can make the determination based on this information. If the recording has not been completed (N), the determination in step S110 is repeated. When the recording is completed (Y), the CPU 14 of the controller 11A sends a command to the device 11B, controls the VTR unit 12 of the device 11B to rewind the tape, and then prompts the device 11B to change the tape (step S111). ). This is because, for example, the CPU 14 of the controller 11A sends a command to prompt the device 11B to change the tape, and the CPU 14 of the device 11B sends the command to the device 11B based on the command.
This can be realized by blinking a lamp associated with the tape eject button on the operation unit 17 of B. Next, the CPU 14 of the controller 11A determines whether an operation of exchanging a tape has been performed in the device 11B (step S112). This determination is made, for example, by the CPU 14 of the device 11B
It is determined whether or not the tape eject button on the operation unit 17 of the controller 1B has been pressed.
1A to the CPU 14 of the controller 11A.
14 can be realized by making a determination based on this information. If the operation of exchanging the tape has not been performed (N), the determination in step S112 is repeated. When the operation of exchanging the tape is performed (Y), the CPU 14 of the controller 11A determines whether the remaining time of the tape in the controller 11A is equal to or less than a predetermined time (step S113). If the remaining time is not shorter than the predetermined time (N), the determination in step S113 is repeated. If the remaining time is equal to or less than the predetermined time (Y), the controller 1
The CPU 14 of 1A returns to step S104 and starts recording the input signal in the device 11B. Less than,
The above operation is repeated.

In such a tape exchange mode, when recording is completed in the controller 11A or the device 11B, unless a tape exchange operation is performed,
The next record is not made. Therefore, the information already recorded on the tape can be protected.

FIG. 9 is a flowchart showing the operation of the information recording system 10 in the repetitive recording mode. In the repetitive recording mode, when recording of an input signal is started in the controller 11A (step S121), the CPU 14 of the controller 11A monitors the remaining time of the tape. That is, the CPU 14 of the controller 11A determines whether the remaining time of the tape in the controller 11A is equal to or shorter than a predetermined time (step S122). If the remaining time is not shorter than the predetermined time (N), step S12
Repeat the judgment of 2. When the remaining time becomes equal to or shorter than the predetermined time (Y), the CPU 14 of the controller 11A presets the time code of the device 11B (step S).
123). The operation of this preset will be described later with reference to FIG.
This will be described in detail with reference to FIG.

Next, the CPU 14 of the controller 11A
Sends a command to the device 11B,
B to start recording the input signal (step S1).
24). Next, the CPU 14 of the controller 11A determines whether or not the remaining time of the tape in the device 11B is equal to or shorter than a predetermined time (Step S125). If the remaining time is not shorter than the predetermined time (N), the determination in step S125 is repeated. When the remaining time becomes equal to or shorter than the predetermined time (Y), the CPU 14 of the controller 11A starts recording the input signal in the controller 11A (step S126).

Next, the CPU 14 of the controller 11A
Determines whether the remaining time of the tape in the controller 11A is equal to or less than a predetermined time (step S127). If the remaining time is not shorter than the predetermined time (N), the determination in step S127 is repeated. When the remaining time becomes equal to or less than the predetermined time (Y), the CPU 14 of the controller 11A
Returning to step S124, recording of the input signal in the device 11B is started. Hereinafter, the above operation is repeated.

In the repetitive recording mode, when the recording is completed in the controller 11A or the device 11B, the tape is automatically rewound.

In the repetitive recording mode, when the recording is completed in the controller 11A or the device 11B, the next recording is performed without replacing the tape. Therefore, the controller 11A and the device 1
1B, the recording can be continued completely automatically, and unless the tape is exchanged in the controller 11A and the device 11B, the latest information of about two tapes can be transferred to the controller 11 from the time when the recording was completed. 11A and device 11B.

FIG. 10 is a flowchart showing step S103 in FIG.
And the device 11B of step S123 in FIG.
6 is a flowchart showing an operation of presetting the time code of FIG. In this operation, first, the CPU of the controller 11A
14 controls the time code generator 13 of the device 11B for the device 11B in the internal mode,
A command for setting the preset mode and the free run mode is sent (step S131). Note that the internal mode is a mode in which a time code generated by the internal time code generator 13 is recorded on a tape. The preset mode is a mode in which a preset (an arbitrary value is set in advance) is possible. The free run mode is a mode in which the time code is automatically advanced. Next, the CPU 14 of the controller 11A similarly operates the time code generator 1 of the controller 11A.
3 is set to the internal mode, the preset mode, and the free run mode (step S132).

Next, the CPU 14 of the controller 11A
Is the time code being read by the controller 11A (step S133), and the read time code is added to the delay by the preset processing (the time from when the time code is read to when the time code is preset in the device 11B; for example, 2). (Approximately a frame) is calculated (step S134). next,
The CPU 14 of the controller 11A incorporates the time code calculated in step S134 into a time code preset command for instructing preset of the time code and transmits the time code to the device 11B (step S135). Then, the operation of presetting the time code ends (return to the operation shown in FIGS. 7 and 8 or the operation shown in FIG. 9). In addition, device 1
The CPU 14 of 1B presets the time code generator 13 of the device 11B based on the time code given by the controller 11A according to the time code preset command given by the controller 11A.

After presetting the time code of the device 11B by such an operation, the controller 11
At A and the device 11B, the time code proceeds in the same way.

As described above, according to the information recording method, the information recording system, and the information recording apparatus according to the present embodiment, the controller 11A and the device 11B work together to automatically generate the same input signal. Since the input signal is recorded continuously using multiple tapes while setting the overlap period for overlapping recording on the tape,
The input signal can be easily recorded continuously using a plurality of tapes. This makes it possible to continuously record information that exceeds the recording time of one tape when recording a concert or the like.

In this embodiment, the time code is recorded on each tape so that the same time code for the same information recorded on a plurality of tapes in the overlap period is the same. In addition, it is possible to easily edit a portion of information recorded over two tapes.

In addition, the recording can be continued completely automatically, and the latest information for about two tapes can be left on the tape retroactively from the time when the recording is completed. Furthermore, since the tape exchange mode and the repetitive recording mode can be selected, the degree of freedom of the usage mode increases.

In this embodiment, the information recording device 1
Each of the information recording devices 11A and 11B is configured such that the input signals are continuously recorded using a plurality of tapes while setting an overlap period in which the same input signal is repeatedly recorded on a plurality of tapes. Includes control means (CPU 14 and memory 15) for performing control for interlocking the VTR unit 12 with each other, so that only the two information recording devices 11A and 11B transmit the same input signal to a plurality of tapes.
