Editing and controlling device for editing section of video tape

The present invention relates to an apparatus for editing recording control of a specific section of a video tape. More particularly, when editing and recording a video tape by two video tape recorders, a plurality of specific sections for video tapes to be played back can be set. A video recording / recording control apparatus for a specific section of a video tape for causing video / audio information recorded in the set specific section to be recorded on a video tape to be recorded.

In general, video tapes useful for repetitive recording and reproducing of video / audio information are structured to have a disparity information recording method, and a video tape recorder that handles a video tape to which such disparity information recording method is applied is a video. According to the setting state of the play / record / rewind / rewind mode for the tape, the mechanism of the tape drive unit performs the function of the set mode while driving the video tape at constant speed / high speed.

Therefore, by appropriately utilizing the repetitive recording / playback function of the information of the videotape, recording / playback of, for example, a broadcast program or an external video / audio signal is possible, and in particular, two videotapecoders are applied. Background Art A method of copying and recording a video / audio signal of a video tape reproduced by a video tape recorder on one side to a video tape of a recording target driven by a video tape recorder on the other side is widely known.

According to such a copy recording method, a video tape recorder on which one of the video tapes to be reproduced is played is transmitted to a video tape recorder on the other side, which drives the video tape of a recording object, and the control data for notifying the start of recording is transmitted. When the video / audio signal read out from the video tape is transmitted to the video tape recorder on the other side, the video tape recorder on the other side synchronously moves the video tape of the recording target according to the control data applied from the video tape recorder on the other side. While driving, the video / audio signal read and applied from the video tape of the playback target is recorded on the video tape of the recording target.

The video / audio copy recording of such a video tape is not limited to the video tape as a source for providing the video / audio information, but also includes a video / audio signal reproduced from, for example, a disc-shaped information recording medium reproducing system.

By the way, in case of copying / recording the video / audio signal provided from either the video tape recorder or the disc-shaped information recording medium reproducing system, it is expected to be convenient in the recording operation. In the recorded state, a specific section can be selectively set to execute edit recording. For example, as a disc-shaped information recording medium, a laser disk in which different video / audio information is recorded on a plurality of tracks is employed. The intention for executing the edit recording is disadvantageous.

That is, according to the copy recording method described as a conventional example, since the entire video / audio signal recorded on the video tape or the disc-shaped information recording medium to be played back is recorded on the video tape to be recorded, unnecessary video / audio information is also recorded. There is no choice but to copy the video tape to the recording object, which is a wasteful factor for the video tape to be recorded.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and if at least one specific section is set for a videotape of a playback object providing a video / audio signal to at least one videotape video tape, the video of the video to be played back only in that specific section is set. It is an object of the present invention to provide an editing recording control apparatus for a specific section of a video tape for recording a video / audio signal applied from a tape.

A tape information receiver 34 for receiving a video / audio signal (i.e., tape information) from the video tape 12 applied by the tape information output section 22 of the reproduction-side VCR 10, and the tape information receiver section. A section determination unit 36 for detecting a synchronization signal of the video signal received at 34 and generating a signal for executing the determination of a specific section according to the present invention, and detecting the synchronization signal at the section determination unit 36. According to the result, a control unit 38 is in charge of controlling to set the recording mode synchronously with the playback side VCR 10, and the recording side VCR 30 is under the control of the control unit 38. Drive video tape 32 of recording object Indicates the tape information (video / audio signal) from the playback side VCR 10 received by the tape information receiver 34 by activation control (EN) by the tape drive unit 40 and the controller 38. The tape information recording processor 42 continuously records on the video tape 34 to be recorded.

FIG. 2 (a) is a view for explaining a configuration example of the remote controller 14 shown in FIG. 1, and the section start position for setting a start position of a section specific to a conventional VCR remote control including a 10-key 14a. A setting key 14b, a section end position setting key 14c, and an editing recording key 14c for setting the editing recording mode of a specific section are further provided.

2 (b) shows the section start position setting key 14a and section end position setting key of the remote controller 14 stored in the data memory 26 provided in the playback-side VCR 10 shown in FIG. A specific section setting state of the video tape 12 by 14c) is shown. That is, the data memory 26 stores the section start position setting key 14a and the section end position of the remote controller 14 while the high speed search mode of the video tape 12 is executed under the control of the controller 16. At the time of operation of the setting key 14c, the count amount of the video tape 12 determined by the timer counter 24 is stored as specific section setting data.

Next, the operation of the video recording control apparatus for specifying a section of the video tape executed by the above-described configuration will be described in detail with reference to the flowchart shown in FIG.

First, according to the editing recording position setting process of the specific section shown in Fig. 3A, the control unit 16 of the playback VCR 10 waits for a high speed in step 50 while waiting for the remote control signal from the remote control unit 14; When the search mode is received, the timer counter 24 is initialized in step 52 and then the tape drive unit 18 is controlled in step 54 to drive the video tape 12 at high speed. The high speed search is executed for the 20, and the number of revolutions of the capstan motor of the tape drive unit 18 is detected as a count in the timer counter 24 and the control unit 16 is executed. Is approved.

If the section start position setting key 14b of the remote controller 14 is operated (YES in step 56) during the execution of such a high-speed search, the controller 16 sets the section start position setting key 14b in step 58. ) Determines the count amount of the timer counter 24 at the time when the) is operated and temporarily stores it.

Subsequently, the control unit 16 proceeds to step 60 and the key from the section end position setting key 14c of the remote controller 14 while executing the continuous high-speed search function for the video tape 12 to be reproduced. When the input is detected and a key input of the section end position setting key 14c is detected (YES in step 60), the control unit 16 determines the count amount of the timer counter 24 at the time of the key input. In step 62, the timer count amount when the section start position setting key 14b is operated in step 56 and the timer count amount when the section end position setting key 14c is operated in step 60 are changed. The data is stored in the data memory 26 as a specific section.

On the other hand, as a result of the determination in step 60, the section of the remote controller 14 for a predetermined time from the state in which the section start position setting key 14b is operated to the time when the high speed search of the video tape 14 is completed. When the end position setting key 14c is not inputted (YES in step 64), the controller 16 automatically cancels the specific section setting process in the fast search mode.

Thus, by the above process, a specific section for editing and recording reproduction is selected on the video tape 12 to be reproduced and stored in the data memory 26 as shown in FIG.

Next, the editing recording process executed in the state where the setting of the specific section in the above-described videotape 12 to be reproduced is completed will be described with reference to the flowchart shown in Fig. 3B.

First, if the control unit 16 of the playback side VCR 10 receives the remote control signal in step 70 while waiting for the remote control signal from the remote control unit 14, the remote control signal is changed to the edit recording key 14d. If it is determined that the signal is a manipulation, and the result of the determination determines that the remote control signal is a signal from the edit recording key 14d, in step 74, the timer counter 24 is initialized, and then the data memory 26 is initialized. The count amount of the first specific section stored (see FIG. 2 (b)) is searched.

Subsequently, the control unit 14 performs high speed on the video tape 12 by the tape drive unit 18 to the section start position (eg, 10) set in the first specific section count amount searched by the data memory 26. Will be driven. In this case, the control section 38 of the recording side VCR 30 is kept in the standby state because the synchronization signal of the tape information received from the tape information receiver 34 is not detected from the section determination section 36. .

If the controller 16 of the playback side VCR 10 determines that the count amount from the timer counter 24 coincides with the start position of the first specific section when the video tape 12 to be played back is running at high speed In step 76, the tape drive unit 18 is controlled to drive the video tape 12 at constant speed, and the tape information playback processing unit 20 is activated to control (EN) the specification of the video tape 12. The tape information (video / audio signal) is read from the start position of the section and applied to the recording side VCR 30 through the tape information output unit 22.

Then, in the recording side VCR 30, the section determining unit 36 applies the detection result of the image synchronization signal to the control unit 38 from the tape information received through the tape information receiving unit 34. Accordingly, the recording side VCR 30 controls the tape drive unit 40 to drive the video tape 32 of the recording object at constant speed, and activates the tape information recording processing section 42. Thus, the tape information received from the playback side VCR 10 received through the tape information receiver 34 is recorded on the video tape 32 of the recording target.

During playback of such an edit recording, the controller 16 of the playback side VCR 10 determines in step 78 the end position of the first specific section in which the timer count amount from the timer counter 24 is set in the data memory 26. For example, it is determined whether or not 50 is reached, and if it is determined that the end position of the first specific section is reached according to the determination result, the tape drive unit 18 moves the video tape 12 in step 80. In addition, the tape information reproduction processing unit 20 is controlled to be in an inactive state to terminate the reproduction operation for the first specific section. In this case, since the video synchronization signal is not detected by the section determining unit 36 in the recording side VCR 30, the control unit 38 controls the tape drive unit 32 to drive the video tape 32. In addition to this, the tape recording operation is stopped by the tape information recording processing section 42.

Subsequently, the control unit 16 of the reproduction-side VCR 10 searches the count amount for the subsequent specific section in the data memory 26, and if a subsequent specific section is searched (YES in step 82). In step 84, the tape drive unit 18 runs the video tape 12 at high speed until the section start position (e.g., 1:10) set in the subsequent specific section count amount. Even in this case, the control unit 38 of the recording-side VCR 30 maintains the pause state because the synchronization signal of the tape information received from the tape information receiver 34 is not detected from the section determination unit 36. Will be.

When the controller 16 of the reproducing side VCR 10 determines that the count amount from the timer counter 24 coincides with the start point of the subsequent specific section by such a high-speed driving operation, the tape drive in step 84 is performed. The unit 18 is controlled to drive the video tape 12 at constant speed, and the tape information reproducing processing unit 20 is activated and controlled to activate (EN) the tape from the start position of the specific section of the video tape 12. Information (video / audio signal) is read and applied to the recording side VCR 30 through the tape information output section 22.

Therefore, the control section 38 of the recording side VCR 30 performs the tape according to the detection result of the image synchronization signal detected by the section determination section 36 from the tape information received through the tape information receiving section 34. The drive unit 40 is controlled to drive the video tape 32 of the recording target at constant speed, and the tape information recording processing unit 42 is activated and received by the tape information receiving unit 34. The tape information from the playback side VCR 10 is continuously recorded on the video tape 32 of the recording target.

During the execution of editing recording for such subsequent specific section, the control unit 16 of the playback-side VCR 10 determines that the amount of timer count from the timer counter 24 is set in the data memory 26 in step 88. It is determined whether a specific section end position (for example, 1:50) is reached, and if it is determined that the subsequent specific section end position is reached according to the determination result, the tape drive unit 18 displays the video by the tape driving unit 18 in step 90. In addition to stopping the running of the tape 12, the tape information reproducing processing unit 20 is controlled to be in an inactive state to end the reproducing operation for the first specific section. In this case, since the video synchronization signal is not detected by the section determining unit 36 in the recording side VCR 30, the control unit 38 controls the tape drive unit 40 to drive the video tape 32. In addition to the above, the editing recording by the tape information recording processing section 42 is stopped, and the editing recording for a specific section set in the data memory 26 is appropriately executed by repeating such a process.

As described above, according to the apparatus for editing and editing a specific section of a video tape according to the present invention, two VCRs are used to continuously edit and record a video tape to be recorded on a specific section of a video tape to be played back. As a result, the wasteful factor in editing and recording of video tapes to be recorded can be greatly reduced compared to the existing editing and recording methods, and unnecessary recording parts can be excluded from video tapes to be played back. The effect can be improved.
