Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip recorder suitable for use in sports broadcasting.

[0002]

2. Description of the Related Art For example, in sports broadcasting, a highlight scene such as a home run scene is often rebroadcast immediately after that or at the end of a program. conventionally,
In such a case, for example, when all the scenes are simultaneously recorded by several VTRs and the highlight scene is re-broadcast, one of the VTRs reproduces and the other VTR continues to record the current situation. Something like that was being done.

Alternatively, for example, a rewritable MO (magneto-optical) disk device is provided with an optical head for recording and an optical head for reproduction, and all the scenes currently performed by the optical head for recording on one MO disk. When re-broadcasting a highlight scene while continuously recording, it was also performed to reproduce only the recorded highlight scene with an optical head for reproduction.

[0004]

However, several VTRs are used.
In the case of using, the equipment becomes large in size and one operator is required for one VTR, so that there is a problem that the labor cost increases. Further, when the MO disk device is used, all the scenes have to be recorded on one MO disk, so that a large capacity MO disk is required, which causes a problem of cost increase.

Here, it is conceivable to separately record on several MO discs having a relatively small capacity, but in this case, a scene recorded on an MO disc different from the MO disc being recorded is reproduced. At least 2 in consideration of broadcasting
There is a problem that one MO disk device is required.
Furthermore, it is conceivable to record repeatedly while overwriting on a single MO disk of small capacity, but with this, it is not possible to save all the scenes, so it is possible to re-broadcast the highlight scene after a long time has passed. Can not be. Further, in this case, there is a problem that the recording is interrupted when the optical head moves from the outermost track to the innermost track of the MO disk.

Therefore, the present invention has solved the above-mentioned problems, and a clip recorder device capable of using a disc having a small capacity and capable of reproducing an arbitrary highlight scene or the like without any trouble. Is proposed.

[0007]

In order to solve the above problems, according to the present invention, an endless recording means for continuously recording an input signal and a signal recorded in the endless recording means are selected. And a clip recording means for recording a signal.

[0008]

As shown in FIG. 1, in sports broadcasting, for example, the input signal SA is input to the endless recording means 2 of the clip recorder device 1, where the input signal SA for a predetermined time is rewritten or overwritten. Continuously recorded by. Here, for example, when the switch 6 is pressed when there is a highlight scene, the number for identifying the highlight scene at that time from the first control means 4 and the amount of data to be stored before and after the highlight scene are displayed. An ID signal is output, which is supplied to the endless recording device 2, the second control device 5, and the clip searching device 7.

Then, of the input signal SA recorded in the endless recording means 2, data for a predetermined time before and after the highlight scene is output as a selection signal SB, which is recorded in the clip recording means 3. At the same time, the ID signal corresponding to the selection signal SB is also recorded in combination with the selection signal SB. In this way, a plurality of highlight scenes are recorded in the clip recording means 3.

When the recorded highlight scene is to be rebroadcast in the middle of sports relay, an ID signal corresponding to the scene is input from the input means 8, and the second ID control is performed via the clip search means 7. It is supplied to the part 5. As a result, of the selection signals SB recorded in the clip recording means 3, the selection signal SB corresponding to the input ID signal is output as the output signal SC, which is rebroadcast.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, one embodiment of the clip recorder device according to the present invention will be described in detail with reference to the drawings.

FIG. 1 shows functional blocks of a clip recorder device 1 according to the present invention. The clip recorder device 1 continuously records the input signal SA without interruption, and at the same time, can reproduce an arbitrary recorded range, and the endless recording means 2. It has a clip recording means 3 for recording a selection signal SB of a predetermined range selected from the signal SA. The clip recording means 3 can also reproduce an arbitrary range simultaneously with the recording process. The endless recording means 2 is controlled by the first control means 4, and the clip recording means 3 is controlled by the second control means 4.
It is controlled by the control means 5. A switch 6 is connected to the first control means 4, and if there is a highlight scene or the like to be saved, the switch 6 is pressed at that scene.

When the switch 6 is pressed, signals for a predetermined time before and after the time when the switch 6 is pressed, for example, 30 seconds before and 30 seconds after are selected and read out from the endless recording means 2, and this selection signal SB is output. It is recorded in the clip recording means 3. Further, the input signal SA at the time when the switch 6 is pressed, that is, one scene of the highlight scene is recorded in the clip search means 7 as a still screen.
Further, at this time, the first control means 4 outputs an ID signal such as a track number to be recorded, which is recorded in the second control means 5 and the clip search means 7. In this way, a predetermined number of combinations of the highlight scene, the predetermined range before and after the highlight scene, and the ID signal are recorded.

When any one of the recorded highlight scenes is rebroadcast, the ID of the highlight scene to be rebroadcast by the input means 8 connected to the clip search means 7 is set. Is entered. Then, the ID signal is supplied to the second control means 5 via the clip search means 7, whereby the highlight scene corresponding to the input ID signal is selected from the highlight scenes recorded in the clip recording means 3. It is output as an output signal SC and rebroadcast. The second control means 5 is connected to a mode setting means 9 for setting a still mode or a slow mode.

FIG. 2 shows the configuration of an embodiment of the clip recorder device 1. In this example, a case where an MO (magneto-optical) disk device is used as the endless recording device 2 and the clip recording device 3 will be described.

In the figure, the input signal SA is recorded in the first memory 11 of the endless recorder section 10. The first memory can store a signal for a predetermined time, for example, 0.5 seconds. As a result, it is possible to eliminate the interruption of the recording when the recording of the MO disk shifts from the outermost track to the innermost track. The output of the first memory 11 is modulated by the modulation circuit 12 and supplied to the recording optical block 13, and the MO disk 14 is heated by the laser light emitted from the recording optical block 13 to reach the Curie temperature or higher. Also, MO
An auxiliary magnetic field generator 15 is arranged on the side of the disk 14 opposite to the recording optical block 13, and the direction of the magnetic field of the portion heated to the Curie temperature or higher is changed by the auxiliary magnetic field to record information. The MO disk 14 is rotationally driven by the spindle motor 16.

In this way, a signal selected from the data recorded on the MO disk 14 is read by the reproducing / erasing optical block 17, and the selection signal SB output from here is read by the clip file recorder unit 30. It is supplied to the second memory 31. Recording optical block 13 and reproducing / erasing optical block 17 of the endless recorder unit 10.
Are servo circuits 1 managed by the first control unit 18, respectively.
It is driven by 9, 20. A switch 21 is connected to the first control unit 18, and according to designation from here,
The reproducing / erasing optical block 17 operates to reproduce the signal recorded on the MO disk 14.

The input signal SA is sent to the endless recorder section 10.
It is also supplied to the monitor 23 of, and if there is a scene to be saved while looking at the screen displayed here, switch 2
1 can be operated. For example, when the switch 21 is pressed when a home run scene or the like is displayed on the monitor 23, recorded data for, for example, 30 seconds before and after that is reproduced and supplied to the second memory 31 of the clip file recorder unit 30. The amount of data reproduced here can be changed and can be arbitrarily set.

An auxiliary magnetic field generator 22 is also arranged on the opposite side of the reproducing / erasing optical block 17 of the MO disk 14, and at the time of erasing, the laser light emitted from the reproducing / erasing optical block 17 is the same as during recording. As a result, a part of the MO disk 14 is heated to the Curie temperature or higher, and the direction of the magnetic field of the heated part is changed by the auxiliary magnetic field generated by the auxiliary magnetic field generating section 22 to erase the data.

The reproducing / erasing optical block 17 performs an erasing operation from the inner track to the outer track of the MO disk 14 prior to the recording optical block 13. Then, when the track reaches the outermost track, the innermost track is sought, and the erase operation is performed again from the innermost track to the outer track. The recording optical block 13 continuously records the modulated input signal SA on the track from which the data has been erased. The recording optical block 13 also performs a recording operation from the inner track to the outer track, and when reaching the outermost track, seeks to the innermost track. Then, the recording operation is performed again from the innermost track toward the outer track.

The erasing operation and the recording operation described above can be modeled as shown in FIG. Here, all tracks of the MO disk 14 are connected together and regarded as one endless track 25, and the recording optical block 13 and the reproducing / erasing optical block 1 are placed on the endless track 25.
7 are arranged at an appropriate interval E. Then, the recording optical block 13 continues recording while maintaining this interval E, and then the reproducing / erasing optical block 17 continues erasing.

In FIG. 2, the recording process of the recording optical block 13 in the normal state, that is, the recording process while moving from the inner track to the outer track and the erasing process of the reproducing / erasing optical block 17 in the normal condition are intermittent. Will be performed. In this case, the recording process and the erasing process are performed at a rate of one track for several rotations of the MO disk 14, for example, five rotations in this example. That is, as shown in FIG. 4, the recording optical block 13 stands by on the same track (A) while the MO disk 14 makes four revolutions. Then, at the fifth rotation, the signal SA that has been input until then and stored in the first memory 11 is recorded in this track (A).

The first memory 11 further stores the input signal SA which is input in about 0.5 seconds required for the recording optical block 13 to seek from the outermost track to the innermost track as described above. After the recording optical block 13 seeks to the innermost track, the input signal SA accumulated in the first memory 11 is output, and this is recorded on the MO disk 14 by the recording optical block 13.
The recording process immediately after the seek to the innermost track is continuous to compensate for the delay time of about 0.5 seconds required for the seek, that is, the recording process is performed at a rate of one track per one rotation of the MO disk 14. Is performed. Then, after the seek delay time is resolved, normal intermittent recording is performed.

In the endless recorder section 10, as shown in FIG. 5, the switch 21 is operated at time t2, for example.
When (FIG. 2) is operated to output the clip command signal SD, the recording ranges C and D for a predetermined time before and after that, for example, 30 seconds before and after that, are set to be reproduced. Here, at the time t2, the recording optical block 1
3 is on the track (d), and at this time, a highlight scene occurs and the switch 21 is pressed, and the clip command signal S
It shows a state in which D is output. Clip command signal S
When D is input to the first control unit 18, the number for distinguishing the highlight scene from other highlight scenes from here, and the reproduction when the scenes before and after this highlight scene are rebroadcast later The amount, in this example, information indicating the playback amount for 30 seconds each before and after the highlight scene is output as an ID, which is the clip file recorder unit 3.
0 to the second control unit 32.

When the switch 21 is pressed, playback /
The erasing operation of the erasing optical block 17 is stopped, and the reproducing / erasing optical block 17 becomes the recording optical block 13.
Seek to the track (b) after the recording range D from the track (d) located at. Next, the reproduction processing is performed by the reproduction / erasure optical block 17. here,
The recorded data is continuously reproduced in synchronization with the rotation of the MO disk 14, that is, at a rate of one track per one rotation of the MO disk without waiting time. Therefore, the reproduction process is performed at a higher speed than in the intermittent recording during normal operation.

After the reproducing / erasing optical block 17 reproduces all the data in the recording range D and reaches the track (2), the reproducing process to the recording range C is further performed at high speed. Playback between recording areas C
The reproduction track where the erasing optical block 17 is located is the track where the recording optical block 13 is located (e)
Then, the reproducing / erasing optical block 17 follows immediately after the recording optical block 13 to perform the same intermittent reproduction as the recording optical block 13, that is, the reproduction is performed at a rate of 1 track per 5 rotations of the MO disk. Processing is performed. After that, the reproducing / erasing optical block 17 is moved to the track
When reaching a track (f) that is a recording range C away from,
The playback operation is stopped. Thereafter, the reproduction / erasure optical block 17 is returned to the last erased track (a), and the erase operation is performed again.

In this case, the reproducing / erasing optical block 17
Time during which the playback process was being performed, that is, switch 2
Time t4 when the reproduction process ends from time t2 when 1 is pressed
Since the erasing operation has not been performed until then, the erasing operation is performed continuously at first to recover the delay by this amount, and therefore at a higher speed than the normal intermittent erasing. Then, when the reproducing / erasing optical block 17 reaches a track (c) separated from the track (g) on which the recording optical block 13 is located by an interval E, normal intermittent erasing is performed, and the optical blocks 13 and 17 are separated by an interval E. Recording and erasing are performed while maintaining a state of being separated from each other.

Now, in FIG. 2, when the switch 21 of the endless recorder unit 10 is pressed in the highlight scene, the ID signal is output from the first control unit 18 as described above, and the reproduction / erasure optical block 17 is also used. Selection signals SB are outputted from the above, and these signals are supplied to the clip file recorder unit 30. Of these, the ID signal is input to and stored in the second controller 32, and the selection signal SB is input to the recording optical block 33.

Then, the servo circuit 34 for driving the recording optical block 33 is controlled by the second controller 32, which drives the recording optical block 33. An auxiliary magnetic field generator 36 is arranged on the opposite side of the MO disk 35 from the recording optical block 33, and the selection signal SB is recorded on the MO disk 35 by driving the recording optical block 33. MO disk 35
Is rotated by a spindle motor 37. The second
When the ID signal is not input to the control unit 32, the recording optical block 33 and the like are in a standby state and stopped.

The selection signal SB output from the reproducing / erasing optical block 17 of the endless recorder unit 10 is not demodulated and is directly recorded in the clip / file recorder unit 30.
Is supplied to the recording optical block 33 of the MO disk 3
Recorded in 5. The second memory 31 located between these optical blocks 17 and 33 is used for time shift in which the rotational phases of the MO disk 35 at which recording starts are matched.

On the other hand, when the switch 21 of the endless recorder unit 10 is pressed, the input signal SA at the time when the switch 21 is pressed is stored in the third memory 52 of the clip search unit 50.
Is stored as a still screen. The third memory 52 has a capacity capable of storing a predetermined number of combinations of such ID signals and still screens. The ID signal and the still screen stored in the third memory 52 are supplied to the monitor 53 and displayed as a search menu on a plurality of sub-screens provided on the screen.

When any one of the highlight scenes displayed on the monitor 53 is rebroadcast during a sports broadcast, the input unit 51 is operated to operate the monitor 53, for example.
Move the cursor on the screen and specify the highlight scene. Then, an ID signal corresponding to the designated highlight scene is output from the third memory 52, and this is output to the second of the clip file recorder unit 30.
It is supplied to the control unit 32.

When the second control section 32 receives the ID signal from the clip search section 50, it controls the servo circuit 38 to drive the reproducing / erasing optical block 39. MO disk 3
An auxiliary magnetic field generating unit 40 is arranged on the side opposite to the reproducing / erasing optical block 39 of FIG. When the reproducing / erasing optical block 39 is driven, the reproducing / erasing optical block 39 is placed at the head of the track of the MO disk 35 in which the selection signal SB is recorded according to the information of the ID signal input to the second controller 32. Are sought, and the selection signal SB recorded over a predetermined range is read. The read selection signal SB is output to the outside as an output signal SC via the demodulation circuit 41 and the fourth memory 42, and is rebroadcast as a highlight scene such as a home run scene during sports relay, for example.

A mode setting unit 43 is connected to the second control unit 32 of the clip / file recorder unit 30,
If a special playback mode, such as slow mode or still mode, is set here, the track and playback
The moving method of the erasing optical block 39 is determined, and special reproduction such as slow reproduction and still reproduction is performed. In this case, the fourth memory 42 is used for temporary freeze of slow playback and still playback. Further, the output signal SC for the time interrupted when the recording / erasing optical block 39 seeks from the outer track to the inner track of the MO disk 35 is stored in the fourth memory 42 in advance, and the reproduction is interrupted. At times, the output signal SC stored in the fourth memory 42 is output. This can prevent interruption of broadcasting.

Furthermore, reproduction of the endless recorder unit 10
By providing a plurality of erasing optical blocks 17 and a plurality of recording optical blocks 33 of the clip file recorder unit 30, it becomes possible to perform a copying process from the endless recorder unit 10 to the clip file recorder unit 30 at high speed. . Although the MO disk device is used in the above embodiment, a disk device such as a hard disk can be used. Further, in the above-described embodiment, the case where the rewritable MO disk 14 is used has been described.
