Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention According to the present invention, a cueing signal (hereinafter referred to as an index signal) is recorded at the beginning of each of a plurality of programs recorded on a magnetic tape, and each program is recorded on the date and time. Is composed of a plurality of different scenes, and in a format in which information indicating recording date and time (hereinafter referred to as time code information) is recorded in each scene, a scene desired by a user or the like can be accurately and quickly obtained. In addition, the present invention relates to a scene search device and a scene search method that allow a user to easily search for a desired scene.

2. Description of the Related Art In recent years, recording devices such as VTRs have been improved in high-density recording and compression recording techniques, and devices capable of recording video signals and audio signals for a long time have been developed. This made it possible to record many programs on magnetic tape.

In order to greatly improve the usability of the user, the reproducing apparatus has been developed with a function of easily searching the program desired by the user from among many programs recorded on the magnetic tape. One of them is
There is a function of recording an index signal in a fixed section at the beginning of a recording section in which each program is recorded, and searching for this signal to locate the desired program.

Further, when recording with a video camera or the like, in order to prevent the number of index signals on the same magnetic tape from increasing too much, for example, the index signal is recorded only after the cassette tape is attached to the video camera. Recording, the first recording after the camera / VTR mode switch was switched, the first recording after the battery was removed, and so on. Therefore, the index signal is not recorded in other recording and stopping operations.

On the magnetic tape thus recorded, a plurality of programs having an index signal recorded at the beginning thereof and a plurality of scenes separated by tape positions where recording dates and times are discontinuous in each program section. And exist.

As a function of searching this scene, a subcode area is provided in the track like a digital VTR or DAT, and the date and time when the video signal or the audio signal of the track is recorded in the subcode area is used as the time code information. This is realized by recording, setting time code information of a scene desired by the user, and driving the magnetic tape until the set time code information is detected from the tape.

[0007]

However, in the above-mentioned conventional configuration, if the user forgets the time code information of the desired scene, the search becomes impossible, and even if the user remembers the time code information, the time code information will be lost. There was a problem that it had to be entered each time, which was troublesome.

Further, when there are a plurality of magnetic tapes or when the same magnetic tape is repeatedly overwritten, is there a scene desired by the user on the magnetic tape currently mounted on the VTR? There was also a problem that the search was performed without clarifying whether or not it was not easy to use.

Further, in the case of detecting the target time code information, if the search is performed at a high speed, the target time code information may be missed. Therefore, the high speed search cannot be performed, and the time required for the search may be shortened. It also had problems such as being expensive.

The present invention solves the above-mentioned conventional problems, and provides a scene search apparatus and a scene search method that can search a scene desired by a user easily and easily in a short time. To aim.

Index signals for recording, and time code information indicating the recording date and time are recorded together with the video and audio signals in the program section. Each program is composed of at least one scene separated by discontinuity points of the time code information. When the scene search is set on the configured magnetic tape, fast rewind is performed at the first speed to the beginning of the magnetic tape, and then the index signal is detected at the fast forward of the second speed from the beginning to detect the index signal. Is detected, the time code information is detected at the third speed fast forward, and the index signal is detected again at the second speed fast forward. In return, at least the time code information when the index signal is detected and the index relative position information indicating the relative position relationship between the detected index signals are created and displayed as program information, and the user desires from the program information. When the program to be selected is selected, the second program is added to the beginning of the desired program based on the index relative position information of the program information.

Index signals for recording, and time code information indicating the recording date and time are recorded together with the video and audio signals in the program section. Each program is composed of at least one scene separated by discontinuity points of the time code information. When a scene search in the direction of the start of the magnetic tape is set in the configured magnetic tape, the index signal is detected from the current tape position by rewinding at the second speed, and the index signal is detected. Fast-forwards to the detected index signal at the second speed, then detects the time code information at the third speed.

The fast rewind is performed at the speed of 4, and then the fast rewind is performed at the third speed while detecting the discontinuous point of the time code information up to the beginning of the desired scene.

[0014]

When the scene search is set by the scene search device (claims 1, 3, and 4), the controller outputs a drive command signal for driving the magnetic tape. Each time the index detecting means detects the index signal while the magnetic tape is being driven, the list information storing means stores the program information created by the list information creating means. The display signal creating means creates a display signal of the stored program information. When a program including a desired scene is selected from the displayed program information, the controller outputs a drive command signal so as to drive the program section selected based on the program information.
Each time the time code detecting means detects a discontinuity of the time code information while driving the selected program section, the list information storing means stores the scene information created by the list information creating means. The display signal creating means creates a display signal of the stored scene information. When the desired scene is selected from the displayed scene information, the controller outputs a drive command signal to search for the desired scene based on the scene information, thereby searching the index signal at high speed and at medium speed. Since the scene search is hierarchically and efficiently performed by combining with the time code information search of (1), it is possible to search the scene desired by the user in a short time, accurately and easily.

Further, when the scene search is set by the scene search method (claims 5 and 7), when the index signal is detected by fast-forwarding from the start end of the magnetic tape, the time code information is detected. By repeating this, program information is created and displayed. When a program including a scene desired by the user is selected from the displayed program information, the program is fast-returned to the beginning of the program selected based on the index relative position information of the program information. Then, the discontinuity of the time code information is detected by fast-forwarding, and the generation and display of the scene information is repeated only for the selected program section. When the user selects a desired scene from the displayed scene information, fast rewind is performed to immediately before the beginning of the desired scene based on the tape position information of the scene information corresponding to the desired scene. After that, by performing fast rewind while detecting the discontinuity of the time code information to the beginning of the desired scene, the index signal search at high speed and the time code information search at medium speed are combined, and hierarchically. Since the scenes are searched efficiently, it is possible to accurately and easily find the scene desired by the user in a short time.

When the scene search in the starting direction of the magnetic tape is set by the scene search method (claims 6 and 7), the index signal is detected by fast rewinding from the current tape position. Then, the fast-forwarding to the beginning of the detected index signal is performed, the time code information is detected thereafter, and the index signal is detected again by the fast-reverse operation, which is repeated to create and display the program information. When a program including a scene desired by the user is selected from the displayed program information, the program is fast-forwarded to the beginning of the program selected based on the index relative position information of the program information.
Next, fast-forward detects the discontinuity in the time code information,
The creation and display of scene information is repeated only for the selected program section. When the user selects a desired scene from the displayed scene information, fast rewind is performed to immediately before the beginning of the desired scene based on the tape position information of the scene information corresponding to the desired scene. After that, rewinding is performed to the beginning of the desired scene while detecting the discontinuity of the time code information. On the contrary, when the scene search toward the end of the magnetic tape is set, if the index signal is detected by fast-forwarding from the current tape position, the time code information is detected and the index signal is detected again by fast-forwarding. Program information is created and displayed by repeating detection. When a program including a scene desired by the user is selected from the displayed program information, the program is fast-returned to the beginning of the program selected based on the index relative position information of the program information. Then, the discontinuity of the time code information is detected by fast-forwarding, and the generation and display of the scene information is repeated only for the selected program section. When the user selects a desired scene from the displayed scene information, fast rewind is performed to immediately before the beginning of the desired scene based on the tape position information of the scene information corresponding to the desired scene. After that, by performing fast rewind while detecting the discontinuity of the time code information to the beginning of the desired scene, the search of the index signal at high speed and the search of the time code information at medium speed are combined,
Since the scenes are searched hierarchically and efficiently, the scene desired by the user can be searched easily and easily in a short time.

FIG. As shown in FIG. 9, three programs A, B, and C are recorded on the magnetic tape 200,
In each program, an index signal is recorded in a fixed section a, b, c from the beginning of the program, the program A is two scenes A1 and A2, and the program B is scenes B1, B2, B3 and B4. Of the four scenes, the program C is assumed to be composed of three scenes C1, C2, and C3. Also, for convenience of explanation, Program A is “Thursday, July 7, 10:00 am

The controller 107 has a light emitting element and a light receiving element for detecting the level of light output from the light emitting element, and determines the leader tape at the end of the tape and the magnetic tape 200 based on the light level detected by the light receiving element. By
The beginning or end of the tape can be detected.

Further, the tape position detecting means 103 can realize the detection of the tape position information by detecting the rotation speed or the rotation cycle of the supply side reel or the winding side reel of the magnetic tape 200.

Further, the maximum speed for fast-forwarding or fast-returning without detecting the information recorded on the magnetic tape 200 is the first speed, and the maximum speed for detecting the index signal is the second speed, the time. The highest speed at which code information can be detected is the third speed, the tape position information can be detected, and the highest speed that does not overshoot the beginning of the scene when decelerated to the third speed at the target tape position. Is the fourth speed, and in DVC, the absolute value of the speed is
The speed is 200 times, the second speed is 200 times, the third speed is 20 times, and the fourth speed is 40 times.

As an example of the scene search operation, the case where the scene B3 is cued from the tape position P4 will be described with reference to the flowchart of FIG. 3 and the operation explanatory diagram of FIG. FIG. 9 shows the locus of the reproducing head (not shown) with respect to the magnetic tape 200 in this case in the tape longitudinal direction.

First, when the operation circuit 108 receives a "scene search" key from the user, it outputs a "scene search" key signal to the controller 107. When the controller 107 receives this key signal, it starts the scene search process.

The controller 107 is the display signal creating means 1
A program information display command signal is output to 06. Upon receiving the program information display command signal, the display signal creation means 106 inputs the program information stored in the list information storage circuit 105, creates a display signal of the program information, and outputs it to the display circuit. Since the program information input at this time does not include all the information of programs A, B, and C, the screen on which the display signal created by the display signal creating means 106 is displayed on the display circuit is as shown in FIG. 4, for example.

Further, the controller 107 outputs a drive command signal for fast return at the first speed to the tape drive circuit 109, and the tape drive circuit 109 drives the magnetic tape 200 to the start end (steps 301 and 302, locus 90).
1).

Next, the controller 107 outputs a search direction signal indicating that the program information is being created toward the end of the tape to the list information creating means 104, and fast-forwards to the tape drive circuit 109 at the second speed. A drive command signal is output (step 303), and the magnetic tape 2
It is determined whether the end of 00 has been reached (step 30).
4).

If the end has not been reached, the controller 107 determines from the key signal from the operation circuit 108 whether or not the user has designated the desired program from the program information (step 305).

When the user has not designated a program, the controller 107 operates the index detecting means 1
It is determined whether or not 01 has detected an index signal from the magnetic tape 200 (step 306).

If no index signal is detected, the process returns to step 303, and steps 303 to 306 are performed until it is determined that the end has been detected, the program has been designated, or the index signal has been detected.
Is repeated (trajectory 902).

When the index detecting means 101 detects the index signal of the program A on the magnetic tape 200 at the tape position P2 in FIG. 9, the controller 107 inputs the detected index signal and the tape drive circuit 10
A drive command signal for fast-forwarding at the third speed is output to 9 to decelerate the magnetic tape 200 (step 307, trajectory 9).
03).

The magnetic tape 200 is moved to the third position at the tape position P3.
When the speed is reduced to the fast-forwarding speed, the list information creating means 104 inputs the time code information constantly detected by the time code detecting means 102, and creates the program information. At this time, the list information creating means 104 inputs a search direction signal indicating a search toward the tape end direction from the controller 107, and the program information of the program A is “program No. is 1, time code is July 7 (Thursday) morning. "10:00" is created (Step 30
8). Then, the list information creating means 104 outputs the created program information and stores it in the list information storage circuit 105.

When the controller 107 confirms that the program information is stored in the list information storage circuit 105,
A program information display command signal is output to the display signal creating means 106. When the display signal creating means 106 receives the program information display command signal, the list information storage circuit 105
The program information stored in the input circuit is input, a display signal for displaying the program information on the display circuit is created, and output to the display circuit.

Again, the controller 107 outputs the fast-forward command signal at the second speed to the tape drive circuit 109 and starts detecting the index signal of the next program (steps 303 to 306, locus 904).

When the index detecting means 101 detects the index signal of the program B from the magnetic tape 200 at the tape position P6 (step 306), the controller 107 causes the tape drive circuit to operate in the same manner as when the index signal of the program A is detected. A drive command signal for fast-forwarding at the third speed is output to 109 (step 307,
Trace 905).

The third magnetic tape 200 is placed at the tape position P7.
When decelerated to the fast-forward at the speed of, the list information creating means 104 inputs the time code information from the time code detecting means 102 and the program information of the program A previously stored in the list information storage circuit 105, and the program of the program B. Create information. At this time, the list information creating means 104 inputs the search direction signal indicating the search in the tape end direction from the controller 107. Is the program No. of the previously created program A. Will be the next number. As a result, the program No. Will be numbered sequentially from the program at the beginning of the tape. Therefore, “program No. is 2, and time code is 6:30 pm on Thursday, July 7” is created as the program information of the program B and added to the previous program information (step 308). Then, the list information creating means 104 outputs the additionally created program information and stores it in the list information storage circuit 105. As a result, the list information storage circuit 105 stores the program information of the programs A and B.

Upon confirming that the program information is newly stored in the list information storage circuit 105, the controller 107 outputs a program information display command signal to the display signal creating means 106. Upon receiving the program information display command signal, the display signal creating means 106 inputs the program information stored in the list information storage circuit 105, creates a display signal for displaying the program information on the display circuit, and outputs the display signal to the display circuit. .

Since the program information input at this time includes the information on the programs A and B, the screen on which the display signal created by the display signal creating means 106 is displayed on the display circuit is, for example, as shown in FIG.

Again, the above processing is repeated to detect the index signal of the program C and to create, store and display the program information (steps 303 to 308, loci 906 to 908).

As described above, the program information of the program A is "program No. is 1 and the time code is 10:00 am on Thursday, July 7", and the program information of the program B is "program No. is 2, The time code is Thursday, July 7th, 6:30 pm ", program C
As the program information of the above, "the program number is 3, and the time code is 8:00 pm on Friday, July 8" is stored in the list information storage circuit 105.

When the controller 107 detects the end of the tape at the tape position P15 (step 304), it immediately outputs a stop drive command signal to the tape drive circuit 109,
The tape drive circuit 109 stops the magnetic tape 200 (step 309). Further, the controller 107 outputs a program information creation end signal to the display signal creation means 106. Upon receiving the program information creation end signal, the display signal creation means 106 creates a display signal that prompts the user to select a program and outputs it to the display circuit. A screen displaying this display signal on the display circuit is, for example, as shown in FIG.

After that, the controller 107 determines whether or not the program desired by the user is designated from the program information stored in the list information storage circuit 105 by the key signal from the operation circuit 108 (step 3).
10).

Steps 309 and 310 are repeated until the user specifies a program. When the user specifies "Program No. 2", that is, program B, the process proceeds to step 311, and the controller 107 causes the display signal to be displayed. A scene information display command signal is output to the creating means 106. When the display signal creating means 106 receives the scene information display command signal, the list information storage circuit 1
The scene information stored in 05 is input, a display signal of the scene information is created, and output to the display circuit. Since the scene information input at this time does not include all the information of the scenes B1, B2, B3, B4, the screen on which the display signal created by the display signal creating means 106 is displayed on the display circuit is as shown in FIG. 7, for example. .

When the controller 107 inputs the "program No. 2" key signal from the operation circuit 108, it outputs a fast return drive command signal at the second speed to the tape drive circuit 109, and the program B is searched for. It starts (step 311). The controller 107 recognizes from the program information input from the list information storage circuit 105 that "program No. 2", that is, the index signal of program B is the second index signal from the current tape position P15 toward the tape start end. Then, until the second index signal is input from the index detection means 101 (step 312), the drive command signal for fast return at the second speed is continuously output (steps 311 and 312, locus 909).

When the second index signal is input, the cueing of program B is completed.

By the way, during the fast-forwarding at the second speed (step 303), before the end of the tape is reached (step 304), when the user designates a desired program (step 305), the second tape is immediately sent. In order to stop the fast-forwarding at the speed of 1 to skip the specified program, the controller 107 sends a second command to the tape drive circuit 109.
A drive command signal for fast return at the speed of is output (step 311). After that, the processing is performed in the same manner as when the tape end is detected (steps 311 and 312).

Next, the controller 107 outputs a fast-forward drive command signal at the third speed to the tape drive circuit 109 to create and display the scene information in the program B section (step 313), and the magnetic tape 200 of the magnetic tape 200 is read. It is determined whether the end has been reached or the designated program section has ended, that is, the program B has ended (step 314). The end of the program B can be determined by the index detection means 101 detecting the index signal recorded at the beginning of the program C and the controller 107 inputting it.

When the end has not been reached and the program B has not ended, the controller 107 determines whether or not the scene desired by the user is designated from the scene information by a key signal from the operation circuit 108. From (step 315).

When the user has not designated a scene, whether the list information creating means 104 has detected a discontinuous point where the time code information constantly input from the time code detecting means 102 suddenly changes. Is determined (step 316).

If the discontinuity point of the time code information is not detected, the process returns to step 313, the end point is detected, the program B is ended, or the scene is designated, or the discontinuity point of the time code information is detected. Steps 313 to 316 are repeated until it is determined that it has been detected (trajectory 910).

At the tape position P5 in FIG. 9, when the list information creating means 104 detects a discontinuity point of the time code information input from the time code detecting means 102, the tape position detecting means 103 constantly detects the tape position. By inputting the information, "scene number is 1, time code is 6:30 pm on Thursday, July 7th, and tape position is P5" is created as scene information (step 317). Then, the list information creating means 104 outputs the created scene information of the scene B1 and stores it in the list information storage circuit 105.

When the controller 107 confirms that the scene information is stored in the list information storage circuit 105, it outputs a scene information display command signal to the display signal creating means 106. Upon receiving the scene information display command signal, the display signal creating means 106 inputs the scene information stored in the list information storage circuit 105, creates a display signal for displaying the scene information on the display circuit, and sends it to the display circuit. Output.

Again, the list information creating means 104 starts detecting the discontinuity point of the time code information indicating the beginning of the next scene (steps 313 to 316, locus 9).
11).

At the tape position P8, the list information creating means 1
04 detects the discontinuity of the time code information input from the time code detecting means 102 (step 31).
6) At the beginning of the scene B1, that is, as in the case where the discontinuity of the time code information was previously detected, the tape position information from the tape position detection means 103 and the scene information previously stored in the list information storage circuit 105 are displayed. Enter and create "Scene No. 2, Time Code is Thursday, July 7, 6:45 pm, Tape position is P8" as scene information,
It is added to the previous scene information (step 317). Then, the list information creating means 104 outputs the additionally created scene information and stores it in the list information storage circuit 105. As a result, the list information storage circuit 105 stores the scene information of the scenes B1 and B2.

Upon confirming that the scene information is newly stored in the list information storage circuit 105, the controller 107 outputs a scene information display command signal to the display signal creating means 106. Upon receiving the scene information display command signal, the display signal creating means 106 inputs the scene information stored in the list information storage circuit 105, creates a display signal for displaying the scene information on the display circuit, and sends it to the display circuit. Output. The display circuit displays the input display signal.

Again, the above processing is repeated, and the scene B
3 and B4, that is, the discontinuity of the time code information is detected (steps 313 to 317, locus 912).
~ 914).

As described above, as the scene information of the scene B1, "Scene No. is 1, time code is July 7 (Thursday).
6:30 pm, tape position is P5 ", and the scene information of scene B2 is" Scene No. is 2, time code is Thursday, July 7, 6:45 pm, tape position is P8 ".
As the scene information of the scene B3, "Scene No. is 3, the time code is Thursday, July 7 at 6:50 pm, the tape position is P9", and the scene information of the scene B4 is "Scene No. is 4". The time code is 7:10 pm on Thursday, July 7, and the tape position is P11 "in the list information storage circuit 105.

When the controller 107 detects the end of the program B at the tape position P12 (step 314),
Immediately, a stop drive command signal is output to the tape drive circuit 109, and the tape drive circuit 109 stops the magnetic tape 200 (step 318). In addition, the controller 10
Reference numeral 7 outputs a scene information creation end signal to the display signal creation means 106. Upon receiving the scene information creation end signal, the display signal creation means 106 creates a display signal prompting the user to select a scene and outputs it to the display circuit. The screen on which the display signal is displayed by the display circuit is, for example, as shown in FIG.

Thereafter, the controller 107 determines whether or not the scene desired by the user is designated from the scene information stored in the list information storage circuit 105.
It is determined by the key signal from 8 (step 319).

Steps 318 and 319 are repeated until the user specifies a scene. When the user specifies a scene, the process proceeds to step 320.

When the controller 107 inputs the "scene No. 3" key signal from the operation circuit 108, it outputs a fast return drive command signal at the fourth speed to the tape drive circuit 109 to start the scene B3. Start (step 32)
0). The controller 107 has a list information storage circuit 105.
It is recognized that the tape position of "Scene No. 3", that is, the scene B3 is P9 from the scene information input from
The tape position information at the position P10, which is the distance L moved from the tape position P9 toward the end of the tape, is the tape position detecting means 1.
Until the input from 03 (step 321), the drive command signal for the fast return at the fourth speed is continuously output (step 3).
20, 321, trajectory 915).

Here, the distance L is the tape amount moved from the fast return at the fourth speed to the fast return at the third speed and the tape position information detected by the tape position detecting means 103. The error amount is set to decelerate from the tape position shifted by a certain distance in the tape end direction from P9 so as not to overshoot the target tape position P9.

When the tape position information of P10 is input from the tape position detecting means 103, the controller 107 outputs a drive command signal for the third speed fast return to the tape drive circuit 109 (step 322), and the time code information. The detection of the discontinuity point of is started (step 323, trajectory 91).
6).

When the controller 107 detects the discontinuity of the time code information at the tape position P9, it means that the cueing of the scene desired by the user, that is, the scene B3 is completed, and the reproduction of the magnetic tape 200 is started ( Step 324, trajectory 917).

Also, during fast-forwarding at the third speed (step 313), before the end of the tape and before the end of program B (step 314), the user designates a desired scene (step 315). ), The controller 107 immediately outputs a drive command signal for fast rewinding at the fourth speed to the tape drive circuit 109 in order to immediately stop the fast-forwarding at the third speed and start the specified scene. (Step 320). After that, the same processing is performed as when the end of the tape is detected or when the program B ends (steps 320 to 324).

As described above, according to the first embodiment, when the scene search is set, the controller 107 outputs a drive command signal for fast rewinding at the first speed to the tape drive circuit 109, and the magnetic tape 200. Rewind to the beginning of. Next, the controller 107 outputs a fast-forwarding drive command signal at the second speed, and then inputs an index signal from the index detecting means 101, and outputs a fast-forwarding drive command signal at the third speed. After that, the list information creating unit 104 determines the index relative position information indicating the relative position relationship between the detected index signals, that is, the program number. And time code information input from the time code detecting means 102 are created as program information,
It is stored in the list information storage circuit 105. Controller 1
07 again outputs the drive command signal for fast-forwarding at the second speed. By repeating the detection of the index signal on the magnetic tape 200 to the end of the tape in this way, program information of the program on the magnetic tape 200 is created. When the user designates a desired program from the program information stored in the list information storage circuit 105,
The controller 107 outputs a drive command signal for fast return at the second speed, and finds the desired program based on the index relative position information of the program information input from the list information storage circuit 105. Next, the controller 107 outputs a fast-forward drive command signal at the third speed. The list information creating means 104 detects a discontinuity point of the time code information input from the time code detecting means 102, and uses the time code information at the discontinuity point and the tape position information at the discontinuity point as scene information. Creating and storing in the list information storage circuit 105 is repeated in the designated program section. List information storage circuit 105
When the user designates a desired scene from the scene information stored in, the controller 107 outputs a drive command signal for fast return at the fourth speed, and the list information storage circuit 10
Based on the tape position information of the scene information input from 5, the drive is performed to a position displaced from the beginning of the desired scene by the distance L in the tape end direction. After that, the controller 107
Outputs a drive command signal for fast return at the third speed, detects a discontinuity point of the time code information input from the time code detecting means 102, and cues a desired scene, thereby achieving high speed. In order to search for scenes hierarchically and efficiently by combining the index signal search of and the search of the discontinuity point of the time code information at medium speed,
A scene desired by the user can be searched easily and easily in a short time.

Further, the program information is created by detecting the index signal at the fast-forwarding at the second speed, decelerating to the fast-forwarding at the third speed to detect the time code information, and again at the fast-forwarding at the second speed. Since it is realized by repeating accelerating and detecting the next index signal,
A scene search can be realized by a simple procedure without performing a complicated operation such as rewinding the amount of overrun at the time of deceleration after detecting the index signal.

If the user designates a desired program from the program information stored in the list information storage circuit 105 until then while the program information is being created at the fast-forwarding speed of the second speed, the controller 107 The fast forward for creating the program information is stopped, the specified program is immediately cued, and while the scene information is being created by the fast forward at the third speed, the list information storage circuit 105 When the user designates a desired scene from the scene information stored in, the controller 107 stops the fast-forwarding for creating the scene information and immediately executes the cueing of the designated scene, which is unnecessary for the user. There is no need to wait for the time to create program information or scene information, When the scene information is created, for immediate start the beginning of the desired program or scene can be searched more efficiently in a short time.

(Second Embodiment) A second embodiment of the present invention will be described below with reference to the drawings.

The second embodiment has the same configuration as that of the first embodiment shown in FIG. 1, and a case of using a scene search method different from that of the first embodiment will be described.

With respect to the scene search device configured as shown in FIG. 1, FIG. 2, FIG. 4, FIG. 7, FIG.
The operation will be described with reference to FIGS. 13 and 14. In the figure, the same parts as those in FIGS. 1 to 9 are designated by the same reference numerals.

FIG. 2 shows D recorded on the magnetic tape 200.
It is the schematic which showed the track format of VC. The track format is as described in the first embodiment.

FIGS. 10 and 11 are flowcharts showing the process at the time of scene search, FIGS. 4, 7, 13, and 14 are explanatory views showing the display screen at the time of scene search, and FIG. 12 is at the time of scene search. FIG. It is assumed that the program and the scene are recorded on the magnetic tape 200 just as in the first embodiment (FIG. 9).

The scene search in the tape end direction and the scene search in the tape start direction will be described below as an example of the scene search operation.

First, as an operation example of the scene search toward the end of the tape, the flow chart of FIG. 10 and FIG. 12 in the case where the scene B3 is cued from the tape position P4.
The operation will be described with reference to FIG. The locus of the reproducing head (not shown) with respect to the magnetic tape 200 in this case in the tape longitudinal direction is shown in FIG.

When the operation circuit 108 receives a "scene search in the tape end direction" key from the user, it outputs a "scene search" key signal to the controller 107.
When the controller 107 receives this key signal, it starts the scene search process.

The controller 107 is the display signal creating means 1
A program information display command signal is output to 06. Upon receiving the program information display command signal, the display signal creation means 106 inputs the program information stored in the list information storage circuit 105, creates a display signal of the program information, and outputs it to the display circuit. Since the program information input at this time does not include all the information of programs A, B, and C, the screen on which the display signal created by the display signal creating means 106 is displayed on the display circuit is as shown in FIG. 4, for example.

Next, the operation circuit 108 outputs a key signal of "search direction is tape end direction" to the controller 107. When the controller 107 receives this key signal, it executes a scene search process in the tape end direction (step 1001 in FIG. 10).

The controller 107 outputs a search direction signal indicating that the program information is being created toward the end of the tape to the list information creating means 104, and also sends a drive command signal to the tape drive circuit 109 for fast-forwarding at the second speed. And the tape drive circuit 109 outputs the magnetic tape 200
Is started by fast-forwarding at the second speed (step 100
2) The controller 107 determines whether the end of the magnetic tape 200 has been reached (step 1003).

If the end has not been reached, the controller 107 determines from the key signal from the operation circuit 108 whether or not the user has designated the desired program from the program information (step 1004).

If the user has not designated a program, the controller 107 determines the index detection means 1
It is determined whether or not 01 has detected an index signal from the magnetic tape 200 (step 1005).

If the index signal is not detected, the process returns to step 1002, and steps 1002 to 1005 are repeated until it is determined that the end is detected, the program is designated, or the index signal is detected (trajectory 1201).

When the index detecting means 101 detects the index signal of the program B from the magnetic tape 200 at the tape position P6 in FIG. 12, the controller 107 inputs the detected index signal and the tape drive circuit 1
Output a drive command signal for fast-forwarding at the third speed to 09,
The magnetic tape 200 is decelerated (step 1006, trajectory 1202).

The third magnetic tape 200 is placed at the tape position P7.
When the speed is reduced to the fast-forwarding speed, the list information creating means 104 inputs the time code information constantly detected by the time code detecting means 102, and creates the program information. At this time, the list information creating means 104 inputs a search direction signal indicating a search toward the tape end direction from the controller 107, and as program information of the program B, "program No. is 1, time code is Thursday, July 7, afternoon. 6:30 ”(Step 100
7). Then, the list information creating means 104 outputs the created program information and stores it in the list information storage circuit 105.

When the controller 107 confirms that the program information is stored in the list information storage circuit 105,
A program information display command signal is output to the display signal creating means 106. When the display signal creating means 106 receives the program information display command signal, the list information storage circuit 105
The program information stored in the input circuit is input, a display signal for displaying the program information on the display circuit is created, and output to the display circuit.

Again, the controller 107 outputs a fast-forward command signal at the second speed to the tape drive circuit 109,
The detection of the index signal of the next program is started (steps 1002 to 1005, locus 1203).

At the tape position P13, when the index detecting means 101 detects the index signal of the program C from the magnetic tape 200 (step 1005), the same as when the index signal of the program B is detected,
The controller 107 outputs a fast-forward drive command signal at the third speed to the tape drive circuit 109 (step 10).
06, trajectory 1204).

When the magnetic tape 200 is decelerated at the tape position P14 to the fast-forwarding at the third speed, the list information creating means 104 stores the time code information from the time code detecting means 102 and previously in the list information storage circuit 105. The program information of the program B is input and the program information of the program C is created. At this time, the list information creating means 104 inputs a search direction signal indicating a search toward the tape end direction from the controller 107, judges that the program C is on the tape end side of the program B, and the program C. Is the program number of the previously created program B. Will be the next number. As a result, the program No. Will be numbered sequentially from the program at the beginning of the tape. Therefore, as the program information of the program C, “program No. is 2, time code is 8:00 pm on Friday, July 8” is created and added to the previous program information (step 1
007). Then, the list information creating unit 104 outputs the additionally created program information, and the list information storage circuit 1
It is stored in 05. As a result, the program B is stored in the list information storage circuit 105 as “program No. 1”.
The program information of the program C is stored as "program No. 2".

Upon confirming that the program information is newly stored in the list information storage circuit 105, the controller 107 outputs a program information display command signal to the display signal creating means 106. Upon receiving the program information display command signal, the display signal creating means 106 inputs the program information stored in the list information storage circuit 105, creates a display signal for displaying the program information on the display circuit, and outputs the display signal to the display circuit. .

The above processing is repeated again (step 1
002-1007). From the above, as the program information of program B, "program No. is 1, time code is 6:30 pm on Thursday, July 7", program C
As the program information of the above, "the program number is 2, and the time code is 8:00 pm on Friday, July 8" is stored in the list information storage circuit 105.

When the controller 107 detects the end of the tape at the tape position P15 (step 1003, locus 12).
05), the stop drive command signal is immediately output to the tape drive circuit 109, and the tape drive circuit 109 outputs the magnetic tape 2
00 is stopped (step 1008). Further, the controller 107 outputs a program information creation end signal to the display signal creation means 106. Upon receiving the program information creation end signal, the display signal creation means 106 creates a display signal that prompts the user to select a program and outputs it to the display circuit. A screen displaying this display signal on the display circuit is, for example, as shown in FIG.

After that, the controller 107 determines whether or not the program desired by the user is designated from the program information stored in the list information storage circuit 105 by the key signal from the operation circuit 108 (step 1).
009).

Steps 1008 and 1009 are repeated until the user designates a program. When the user designates "program No. 1," that is, program B, the process proceeds to step 1010 and the controller 107 displays the display signal. A scene information display command signal is output to the creating means 106. Upon receiving the scene information display command signal, the display signal creation means 106 inputs the scene information stored in the list information storage circuit 105, creates a display signal of the scene information, and outputs it to the display circuit. The scene information input at this time includes scenes B1, B2, B3, B4.
Display signal creating means 10 since all the information of
A screen displaying the display signal created by 6 on the display circuit is as shown in FIG. 7, for example.

When the controller 107 inputs the key signal of "Program No. 1" from the operation circuit 108, it outputs a drive command signal for fast rewinding at the second speed to the tape drive circuit 109 to search for the beginning of the program B. Start (step 1010). The controller 107 recognizes from the program information input from the list information storage circuit 105 that the index signal of "program No. 1," that is, the program B, is the second index signal from the current tape position P15 toward the tape start end. However, until the second index signal is input from the index detection means 101 (step 1011), the drive command signal for fast return at the second speed is continuously output (steps 1010, 10).
11, trajectory 1206).

When the second index signal is input, the cueing of program B is completed.

By the way, during fast-forwarding at the second speed (step 1002), before the end of the tape is reached (step 1003), if the user designates a desired program (step 1004), the second speed is immediately set. In order to stop the fast-forwarding at the speed of and to start the specified program, the controller 107 drives the tape drive circuit 109.
A drive command signal for fast return at the second speed is output to (step 1010). After that, the same processing is performed as when the tape end is detected (steps 1010 and 101).
1).

Thereafter, in the program section designated by the user, the scene information is created when the list information creating means 104 detects a discontinuity of the time code information,
The created scene information is stored in the list information storage circuit 105, the display signal of the scene information created by the display signal creation means 106 is displayed on the display circuit, the scene desired by the user is designated, and the controller 107 is designated by the user. The beginning of the scene (steps 313 to 3 in FIG. 10).
24, loci 1207 to 1214), but these processes are exactly the same as in the first embodiment.

Next, as an example of a scene search operation in the tape start direction, a case where the scene B3 is cued from the tape position P19 will be described with reference to the flowcharts of FIGS. 10 and 11 and the operation explanatory diagram of FIG. The locus of the reproducing head (not shown) with respect to the magnetic tape 200 in this case in the tape longitudinal direction is shown in FIG.

When the operation circuit 108 receives a "scene search in the tape start end direction" key from the user, it outputs a "scene search" key signal to the controller 107.
When the controller 107 receives this key signal, it starts the scene search process.

The controller 107 is the display signal creating means 1
A program information display command signal is output to 06. Upon receiving the program information display command signal, the display signal creation means 106 inputs the program information stored in the list information storage circuit 105, creates a display signal of the program information, and outputs it to the display circuit. Since the program information input at this time does not include all the information of programs A, B, and C, the screen on which the display signal created by the display signal creating means 106 is displayed on the display circuit is as shown in FIG. 4, for example.

Next, the operation circuit 108 outputs a key signal "the search direction is the tape start end direction" to the controller 107. When the key signal is input, the controller 107 executes a scene search process in the tape start end direction (step 1001 in FIG. 10).

The controller 107 outputs a search direction signal indicating that the program information is being created in the tape start end direction to the list information creating means 104, and also instructs the tape drive circuit 109 to perform a fast-return drive command at the second speed. A signal is output and the tape drive circuit 109 causes the magnetic tape 200
Drive is started by rewinding at the second speed (step 1101 in FIG. 11), and the controller 107 causes the magnetic tape 200
It is determined whether or not the start point of the
2).

If the start end has not been reached, the controller 107 determines from the key signal from the operation circuit 108 whether or not the user has designated a desired program from the program information (step 1103).

When the user has not designated the program, the controller 107 determines the index detection means 1
It is determined whether or not 01 has detected an index signal from the magnetic tape 200 (step 1104).

If the index signal is not detected, the process returns to step 1101 and steps 1101 to 1 are executed until it is determined that the start end is detected, the program is designated, or the index signal is detected.
104 is repeated (trajectory 1221).

At the tape position P13 in FIG. 12, the index detecting means 101 reads the program C from the magnetic tape 200.
When the controller 107 inputs the detected index signal, the controller 107 starts outputting a fast-forward drive command at the second speed to the tape drive circuit 109 (step 1105), and detects the program C index signal again. Until (step 1106), the drive command is continuously output. This is because when the magnetic tape 200 is stopped after the index signal of the program C is detected by a very fast rewind such as the second speed, the tape that has passed the program C when the magnetic tape 200 is actually stopped. Since the position P18 is reached (trajectory 122
2) Processing for driving the magnetic tape 200 so as to return to the beginning of the program C, that is, the index signal of the program C (trajectory 1223).

After returning to the index signal of the program C, the controller 107 sends the tape drive circuit 109 a third signal.
The drive command signal for fast-forwarding at the speed is output to decelerate the magnetic tape 200 (step 1107, trajectory 122).
4).

When the magnetic tape 200 is decelerated to the fast-forward at the third speed at the tape position p14, the list information creating means 104 inputs the time code information constantly detected by the time code detecting means 102 to create program information. To do. At this time, the list information creating means 104 inputs a search direction signal indicating a search in the tape start end direction from the controller 107, and the program information of the program C is “program No. is 1, time code is Friday, July 8 pm. 3:00 "is created (step 110
8). Then, the list information creating means 104 outputs the created program information and stores it in the list information storage circuit 105.

When the controller 107 confirms that the program information is stored in the list information storage circuit 105,
A program information display command signal is output to the display signal creating means 106. When the display signal creating means 106 receives the program information display command signal, the list information storage circuit 105
The program information stored in the input circuit is input, a display signal for displaying the program information on the display circuit is created, and output to the display circuit.

Again, the controller 107 outputs a drive command signal for fast rewinding at the second speed to the tape drive circuit 109 (step 1109).

At the tape position P13, the index detecting means 101 detects the index signal of the program C, but the controller 107 ignores this (step 11
10) The drive command signal for fast return at the second speed is continuously output as it is (step 1101), and the index signal of the program B, which is the next program, is detected.
(Steps 1101-1104, locus 1225).

At the tape position P6, when the index detecting means 101 detects the index signal of the program B from the magnetic tape 200 (step 1104), the controller 107 causes the tape drive circuit to operate in the same manner as when the index signal of the program C is detected. The output of the fast-forward drive command signal at the second speed to 109 is started (step 11
05) until the index signal of the program B is detected again (step 1106), the drive command is continuously output (trajectory 1226, 1227).

After returning to the index signal of the program B, the controller 107 sends the tape drive circuit 109 a third signal.
The drive command signal for fast-forwarding at the speed of is output (step 1107, locus 1228).

At the tape position P7, the magnetic tape 200 is moved to the third position.
When decelerated to the fast-forward at the speed of, the list information creating means 104 inputs the time code information from the time code detecting means 102 and the program information of the program C previously stored in the list information storage circuit 105, and the program of the program B is input. Create information. At this time, the list information creating means 104 inputs a search direction signal indicating a search in the tape start end direction from the controller 107, judges that the program B is on the tape start end side of the program C, and the program information of the program B is " The program number is 1 and the time code is Thursday, July 7 at 6:03 pm
"0 minutes" and "program No. is 2 and time code is 3:00 pm on Friday, July 8" as the program information of the program C (step 1108). That is, the program information of the previously created program C is changed from “program No. 1” to “program No. 2”, and the program information of the program B created this time is set to “program No. 1”. Program No. The program with the smaller number of is set to be closer to the tape start side. Then, the list information creating means 10
4 outputs the created program information and stores it in the list information storage circuit 105. Thus, the list information storage circuit 105 stores the program information of the program B as “program No. 1” and the program information of the program C as “program No. 2”.

Upon confirming that the program information is newly stored in the list information storage circuit 105, the controller 107 outputs a program information display command signal to the display signal creating means 106. Upon receiving the program information display command signal, the display signal creating means 106 inputs the program information stored in the list information storage circuit 105, creates a display signal for displaying the program information on the display circuit, and outputs the display signal to the display circuit. .

The above processing is repeated again to detect the index signal of the program A and to create, store and display the program information (steps 1101 to 1108,
Trajectories 1229-1233).

As described above, the program information of the program A is “program No. is 1 and the time code is 10:00 am on Thursday, July 7”, and the program information of the program B is “program No. is 2, The time code is Thursday, July 7th, 6:30 pm ", program C
As the program information of the above, "the program number is 3, and the time code is 8:00 pm on Friday, July 8" is stored in the list information storage circuit 105.

When the controller 107 detects the tape start end at the tape position P1 (step 1102), it immediately outputs a stop drive command signal to the tape drive circuit 109,
The tape drive circuit 109 stops the magnetic tape 200 (step 1111). Further, the controller 107 outputs a program information creation end signal to the display signal creation means 106. Upon receiving the program information creation end signal, the display signal creation means 106 creates a display signal that prompts the user to select a program and outputs it to the display circuit.
A screen displaying this display signal on the display circuit is, for example, as shown in FIG.
become that way.

After that, the controller 107 determines whether or not the program desired by the user is designated from the program information stored in the list information storage circuit 105 by the key signal from the operation circuit 108 (step 1).
112).

Steps 1111 and 1112 are repeated until the user designates a program. When the user designates "program No. 2", that is, program B, the process proceeds to step 1113 and the controller 107 displays the display signal. A scene information display command signal is output to the creating means 106. Upon receiving the scene information display command signal, the display signal creation means 106 inputs the scene information stored in the list information storage circuit 105, creates a display signal of the scene information, and outputs it to the display circuit. The scene information input at this time includes scenes B1, B2, B3, B4.
Display signal creating means 10 since all the information of
A screen displaying the display signal created by 6 on the display circuit is as shown in FIG. 7, for example.

When the controller 107 inputs the key signal of "Program No. 2" from the operation circuit 108, it outputs a fast-forward drive command signal at the second speed to the tape drive circuit 109 to start the beginning of the program B. (Step 1113). The controller 107 recognizes from the program information input from the list information storage circuit 105 that the index signal of "program No. 2", that is, the program B, is the second index signal from the current tape position P1 toward the tape end direction. Then, until the second index signal is input from the index detection unit 101 (step 1114), the fast forward drive command signal at the second speed is continuously output (steps 1113 and 111).
4, trajectory 1234).

When the second index signal, that is, the index signal of the program B is input, the controller 107 outputs a drive command signal for fast rewinding at the second speed to the tape drive circuit 109 (step 1115), The drive command signal is continuously output until the index signal of the program B is input again (step 1116) (trajectory 1).
235-1236).

When the index signal of the program B is input again, the cueing of the program B is completed (trajectory 1237).

By the way, during the fast rewind at the second speed (step 1101), if the user specifies the desired program (step 1103) before the tape start end is reached (step 1102), it is necessary to immediately execute the first program. In order to stop the fast rewind at the speed of 2 and perform the beginning of the specified program, the controller 107 causes the tape drive circuit 109
A drive command signal for fast-forwarding at the second speed is output to (step 1113). After that, the same processing is performed as when the tape start end is detected (steps 1113 to 111).
6).

Thereafter, in the program section designated by the user, the scene information is created when the list information creating means 104 detects a discontinuity of the time code information,
The created scene information is stored in the list information storage circuit 105, the display signal of the scene information created by the display signal creation means 106 is displayed on the display circuit, the scene desired by the user is designated, and the controller 107 is designated by the user. The beginning of the scene (steps 313 to 3 in FIG. 10).
24, trajectories 1238 to 1245), but these processes are exactly the same as in the first embodiment.

As described above, according to the second embodiment, when the scene search toward the end of the tape is set, the controller 107 outputs a fast forward drive command signal at the second speed to the tape drive circuit 109. After that, when the index signal is input from the index detecting means 101, a drive command signal for fast-forwarding at the third speed is output. After that, the list information creating unit 104 determines the index relative position information indicating the relative position relationship between the detected index signals, that is, the program number. And the time code information input from the time code detecting means 102 are created as program information and stored in the list information storage circuit 105. The controller 107 outputs the fast-forward drive command signal at the second speed again. By thus repeating the detection of the index signal on the magnetic tape 200 from the tape position where the scene search toward the tape end direction is started to the tape end, the tape search is started from the tape position where the scene search is started on the magnetic tape 200. Program information of programs existing up to is created. When the user designates a desired program from the program information stored in the list information storage circuit 105, the controller 107 outputs a drive command signal for fast return at the second speed, and the program input from the list information storage circuit 105. A desired program is cued based on the information index relative position information. When the scene search in the tape start direction is set, the controller 107 causes the tape drive circuit 1 to operate.
Output the drive command signal of the fast return at the second speed to 09,
After that, when an index signal is input from the index detection means 101, a drive command for fast-forwarding at the second speed is output to the tape drive circuit 109, and when an index signal is input again from the index detection means 101, fast-forwarding at the third speed is performed. The drive command signal of is output. After that, the list information creating means 104 creates the index relative position information and the time code information as program information and stores them in the list information storage circuit 105. Controller 107
Outputs the drive command signal for rewinding at the second speed again. By thus repeating the detection of the index signal on the magnetic tape 200 from the tape position at which the scene search in the tape start direction is started to the tape start end, the tape search is started from the tape position at which the scene search on the magnetic tape 200 is started. Program information of programs existing up to is created. When the user designates a desired program from the program information stored in the list information storage circuit 105, the controller 107 outputs a fast forward drive command signal at the second speed, and the list information storage circuit 1
The desired program is searched for based on the index relative position information of the program information input from 05.
After completing the search for the desired program both in the case where the scene search in the tape end direction and the scene search in the tape start direction are executed, the controller 107 sends the drive command signal for the fast forward at the third speed. Is output. The list information creating means 104 detects a discontinuity point of the time code information input from the time code detecting means 102, and uses the time code information at the discontinuity point and the tape position information at the discontinuity point as scene information. Creating and storing in the list information storage circuit 105 is repeated in the designated program section. List information storage circuit 10
When the user designates a desired scene from the scene information stored in 5, the controller 107 outputs a drive command signal for fast return at the fourth speed, and the list information storage circuit 1
Based on the tape position information of the scene information input from 05, the tape is driven to a position displaced by the distance L in the tape end direction from the beginning of the desired scene. After that, the controller 10
7 outputs a fast-reverse drive command signal at the third speed, detects a discontinuity point of the time code information input from the time code detecting means 102, and cues a desired scene, thereby achieving high speed. In order to find the scene in a hierarchical and efficient manner by combining the index signal search at time and the discontinuity point search of the time code information at medium speed, the user desires accurately in a short time. You can easily search for the desired scene.

Further, the user can specify whether the scene search is in the tape end direction or the tape start direction, and only the program existing in the specified direction from the tape position at the start of the search is detected. By creating the program information, if the user knows in advance whether the scene that the user wants to cue from is the tape end direction or the tape start end direction from the current tape position, the program information of the opposite direction program unnecessary for the user Since it is not necessary to wait for the time to create, it is possible to search more efficiently and in a short time.

If the user designates a desired program from the program information stored in the list information storage circuit 105 until then while the program information is being created by the fast-forward or fast-reverse at the second speed, The controller 107 stops the fast forward or the fast rewind for creating the program information, immediately executes the cueing of the designated program, and while the scene information is being created at the third speed of the fast forward, List information storage circuit 1
When the user designates a desired scene from the scene information stored in 05, the controller 107 stops the fast-forwarding for creating the scene information, and immediately performs cueing of the designated scene, which is unnecessary for the user. There is no need to wait for the time to create the appropriate program information or scene information, and when the desired program information or scene information is created, the beginning of the desired program or scene can be started immediately. You can search.

The magnetic tape is drive-controlled based on the drive command signal.

The operation of the scene search device configured as described above will be described with reference to FIGS. 2, 10, 11, and 12 when the same scene search method as in the second embodiment is used. . In the figure, the same components are designated by the same reference numerals.

FIG. 2 shows D recorded on the magnetic tape 200.
It is the schematic which showed the track format of VC. The track format is as described in the first embodiment.

FIG. 10 and FIG. 11 are flowcharts showing the processing at the time of scene search, and FIG. 12 is an operation explanatory diagram at the time of scene search. It is assumed that the program and the scene are recorded on the magnetic tape 200 just as in the first and second embodiments.

First, the processing procedure of the scene search toward the end of the tape is executed according to the flowchart of FIG. 10 (steps 1001 to 1011 and steps 313 to 32).
4). Also, as an operation example, from the tape position P4 to the scene B
The description in the case of performing the cue of No. 3 is as described in the second embodiment, and the locus in the tape longitudinal direction of the reproducing head (not shown) with respect to the magnetic tape 200 in this case is shown in FIG.
2 (a).

Here, the list information creating means 1504 constantly inputs the tape position information from the tape position detecting means 103, and when searching the index signal of the next program in steps 1002 to 1005 of FIG. 10,
From the change in the input tape position information, it is recognized whether the direction in which the program information is searched is the tape start direction or the tape end direction. That is, when the tape position information value changes so as to increase, it is recognized that the tape end direction is searched, and when the tape position information value decreases, it is recognized that the tape start direction is searched. In the case of a scene search in the tape end direction, the list information creating means 1504 recognizes that the program search direction is the tape end direction.

Then, tape positions P6 and P13 in FIG.
After the index detection means 101 detects the index signal from the magnetic tape 200 at (step 100
5,1006) Create program information (step 1)

Of the program that previously detected Next number. As a result, the program No. Will be numbered sequentially from the program at the beginning of the tape.

Next, the processing procedure of the scene search in the tape start end direction is executed according to the flowcharts of FIGS. 10 and 11 (step 1001 of FIG. 10, steps 1101 to 1116 of FIG. 11, and steps 313 to 32 of FIG. 10).
4). Further, as an operation example, the case where the scene B3 is cued from the tape position P19 is as described in the second embodiment, and the tape of the reproducing head (not shown) for the magnetic tape 200 in this case. The locus in the longitudinal direction is shown in FIG.

Here, the list information creating means 1504 constantly inputs the tape position information from the tape position detecting means 103, and when searching the index signal of the next program in steps 1101 to 1104 of FIG.
Based on the change in the input tape position information, it is determined that the search direction of the program is the tape end direction.
4 will be recognized.

Then, the tape positions P2, P6 and P6 in FIG.
In P13, the index detecting means 101 causes the magnetic tape 20
After detecting the index signal from 0 (step 1
104 to 1107) When the program information is created (step 1108), the list information creating means 1504 recognizes that the search direction of the program is the tape start end direction. Is set to 1, and the program No. of the previously detected program is set. Rewrite the numbers one by one. This allows program N
o. Will be numbered sequentially from the program at the beginning of the tape.

In the other processes, the scene B3 is searched for by the same procedure as in the second embodiment.

As described above, according to the third embodiment, when the scene search in the tape end direction is set, the controller 107 outputs the fast-forward drive command signal at the second speed to the tape drive circuit 109. After that, when the index signal is input from the index detecting means 101, a drive command signal for fast-forwarding at the third speed is output. After that, the list information creating unit 104 determines the index relative position information indicating the relative position relationship between the detected index signals, that is, the program number. And the time code information input from the time code detecting means 102 are created as program information and stored in the list information storage circuit 105. The controller 107 outputs the fast-forward drive command signal at the second speed again. By thus repeating the detection of the index signal on the magnetic tape 200 from the tape position where the scene search toward the tape end direction is started to the tape end, the tape search is started from the tape position where the scene search is started on the magnetic tape 200. Program information of programs existing up to is created. When the user designates a desired program from the program information stored in the list information storage circuit 105, the controller 107 outputs a drive command signal for fast return at the second speed, and the program input from the list information storage circuit 105. A desired program is cued based on the information index relative position information. When the scene search in the tape start direction is set, the controller 107 causes the tape drive circuit 1 to operate.
Output the drive command signal of the fast return at the second speed to 09,
After that, when an index signal is input from the index detection means 101, a drive command for fast-forwarding at the second speed is output to the tape drive circuit 109, and when an index signal is input again from the index detection means 101, fast-forwarding at the third speed is performed. The drive command signal of is output. After that, the list information creating means 104 creates the index relative position information and the time code information as program information and stores them in the list information storage circuit 105. Controller 107
Outputs the drive command signal for rewinding at the second speed again. By thus repeating the detection of the index signal on the magnetic tape 200 from the tape position at which the scene search in the tape start direction is started to the tape start end, the tape search is started from the tape position at which the scene search on the magnetic tape 200 is started. Program information of programs existing up to is created. When the user designates a desired program from the program information stored in the list information storage circuit 105, the controller 107 outputs a fast forward drive command signal at the second speed, and the list information storage circuit 1
The desired program is searched for based on the index relative position information of the program information input from 05.
After completing the search for the desired program both in the case where the scene search in the tape end direction and the scene search in the tape start direction are executed, the controller 107 sends the drive command signal for the fast forward at the third speed. Is output. The list information creating means 104 detects a discontinuity point of the time code information input from the time code detecting means 102, and uses the time code information at the discontinuity point and the tape position information at the discontinuity point as scene information. Creating and storing in the list information storage circuit 105 is repeated in the designated program section. List information storage circuit 10
When the user designates a desired scene from the scene information stored in 5, the controller 107 outputs a drive command signal for fast return at the fourth speed, and the list information storage circuit 1
Based on the tape position information of the scene information input from 05, the tape is driven to a position displaced by the distance L in the tape end direction from the beginning of the desired scene. After that, the controller 10
7 outputs a drive command signal for fast return at the third speed, detects a discontinuity point of the time code information input from the time code detection means 102, and cues a desired scene, thereby achieving high speed. In order to find the scene in a hierarchical and efficient manner by combining the index signal search at time and the discontinuity point search of the time code information at medium speed, the user desires accurately in a short time. You can easily search for the desired scene.

Since the index relative position information of the program information is created from the tape position information constantly input from the tape position information detecting means 103, the scene search can be realized with a simple structure.

In the first, second and third embodiments, the program information is composed of time code information and index relative position information when the index signal is detected. Program name, genre, channel information (stationary VT
In the case of R), if the tape position information and the information of the image at an arbitrary position in the program are added and displayed, the usability of the user becomes better.

Further, in the third embodiment, the list information creating means 1504 searches the program depending on whether the value of the tape position information constantly input from the tape position information detecting means 103 is large or small. Although it was supposed to create the index relative position information,
The tape position information of the position where the index signal of each program is detected may be stored and the index relative position information may be created by comparing the tape position information.

In the first, second, and third embodiments, the scene information includes time code information at discontinuous points of time code information and tape position information at discontinuous points. However, if a scene name, a genre name, channel information (in the case of a stationary VTR), an image at an arbitrary position in the scene, and the like are additionally displayed, the usability of the user is further improved. Although the tape position information is not displayed in the example of the scene information display screen (FIGS. 7 and 8), it goes without saying that the tape position information may be displayed.

In the first, second, and third embodiments, the program information or the scene information includes the tape position information so that the desired program or the desired scene can be found. After performing as described above, it is possible to compare the tape position information of the program information or the scene information with the current tape position information to confirm whether the cueed position is the beginning of the desired program or scene. Accurate scene search can be realized.

Further, in the first, second and third embodiments, the time code information is month and day,
Although the day of the week and the time of day are set, it is possible to freely set the year without adding to it, as long as the user can understand the contents of the program or scene, such as adding a year and conversely excluding the day of the week.

Also, in the first, second and third embodiments, the display signal creating means 106 is used.
Is a display circuit that creates a program information display screen or a scene information display screen when receiving a program information display command signal, a scene information display command signal, a program information creation end signal, or a scene information creation end signal from the controller 107. However, the display signal creating means 106 creates and outputs the program information display screen or the scene information display screen at all times or at an arbitrary timing, or the list information storage circuit 105. The list information storage circuit 105 outputs the updated program information or scene information to the display signal creating means 106 only when the program information or scene information stored in the above is updated, and the display signal creating means 106 creates a display screen. Then, it may be output.

Further, in the first, second and third embodiments, the index detecting means 10 is used.
1 is an index signal, the time code detecting means 102
The tape position detecting means 103 always detects the tape position information, but it goes without saying that the time code information may be detected as necessary.

Further, in the first, second, and third embodiments, the scene designated by the user to specify the desired scene (step 315, step 319 in FIG. 3 or FIG. 10) The fourth speed fast return is performed to the tape position shifted from the beginning tape position in the tape end direction by the distance L (steps 320 and 321),
After that, while detecting the discontinuity of the time code information, the third
The desired scene is cued by reversing the speed of (step 322, 323), but the discontinuity of the time code information should be detected immediately after the user specifies the desired scene. Therefore, the scene search can be realized even if the desired scene is searched for. In this case, for example, when the third speed is equal to or higher than the fourth speed, the scene search can be more efficiently performed in a short time.

Further, in the first, second, and third embodiments, when the index signal is detected during fast forward or fast reverse at the second speed during program information creation, the program If specified,
Although it is assumed that the cueing of the specified program is started immediately, the process is not limited to this, and the steps 303 to 303 in FIG.
308, steps 1002-1007 in FIG. 10, FIG.
Needless to say, even if a program is designated during the execution of steps 1101 to 1110, the cueing may be started immediately. Similarly, step 3 in FIG. 3 or FIG.
Needless to say, even if a scene is designated during execution of steps 13 to 317, cueing of the designated scene may be started immediately.

In the first, second, and third embodiments, the reproduction of the designated scene is completed and the reproduction is completed (step 324 of FIG. 3 or FIG. 10). However, without being limited thereto, it can be applied to various functions such as stop and recording.

Further, in the first, second and third embodiments, it has been explained that when the scene search is set, the program information or the scene information is created from the beginning. If the list information storage circuit 105 has already stored the program information or the scene information of the magnetic tape 200 currently mounted when is set, it may be configured not to recreate the program information or the scene information. If so, the scene search can be realized in a shorter time. In the case of this configuration, when the program or the scene is recorded after the program information or the scene information is created, the program information or the scene information is sequentially updated.

Further, in the first, second and third embodiments, the tape position detecting means 103 is used.
Suppose that the tape position information is detected by detecting the rotation speed or the rotation cycle of the supply-side reel or the winding-side reel. However, other than that, for example, the remaining tape value or the absolute value recorded on the magnetic tape 200 is used. The tape position information can be detected from the absolute position code indicating the tape position and information corresponding to or convertible from the absolute position code.

In the first, second, and third embodiments, the fourth speed can detect the tape position information, and the third speed can be detected at the target tape position. The maximum speed that does not overshoot the beginning of the scene when decelerating to was set as the maximum speed, but the tape position information can be detected, and the maximum speed is arbitrarily determined by the distance between the current tape position and the target tape position. Then, the scene search can be realized in a shorter time.

In the first and second embodiments, the search direction signal output from the controller 107 indicates whether the program information is created in the tape start end direction or the tape end direction, The search direction signal is set immediately before the search, but the search direction signal may be set in the direction indicated by the drive command signal. Since the program information of the first embodiment is always created from the tape start end side toward the tape end direction, the search direction signal may not be used.

In the second embodiment, when the scene search in the tape end direction is set, the current tape position to the tape end is set, and when the scene search in the tape start end direction is set, the current tape position is set. I explained that the program information is created up to the beginning of the tape, and after that, if the user does not specify a program from the created program information, it does not move to the next processing. For example, if no program is specified for a certain period of time When the key signal of “or reverse direction program information creation” is input, the user can start creating program information of the program existing in the opposite direction from the first tape position where scene search is set. More convenient to use.

Further, in the first, second, and third embodiments, only the case of the DVC is described, but the information indicating the beginning of the program on the magnetic tape 200 and the program thereof are described. Alternatively, if the scene or the information indicating the date and time when the track is recorded is recorded, it can be implemented.

[0161]

As described above, according to the present invention, since a high-speed index signal search and a medium-speed time code information search are combined to perform a hierarchical and efficient scene search, It is possible to accurately and easily retrieve a scene desired by the user in time.

Also, the index relative position information in the program information is determined from the tape position information input from the tape position detecting means and created, whereby a scene search can be realized with a simple structure.

Further, the program information is created by detecting the index signal at the fast-forward of the second speed, decelerating to the fast-forward of the third speed to detect the time code information, and then again at the fast-forward of the second speed. Since it is realized by repeating accelerating and detecting the next index signal,
The scene search can be realized by a simple procedure without performing a complicated operation such as rewinding an overrun portion during deceleration after detecting the index signal.

Further, the user can specify whether the scene search is in the tape end direction or in the tape start end direction, and only the programs existing in the specified direction from the tape position at the start of the search are detected. By creating the program information, if the user knows in advance whether the scene that the user wants to cue from is the tape end direction or the tape start end direction from the current tape position, the program information of the opposite direction program unnecessary for the user Since it is not necessary to wait for the creation time, it is possible to search more efficiently and in a short time.

Also, there is no need to wait for the time for creating unnecessary program information or scene information for the user,
When the desired program information or scene information is created, the cueing of the desired program or scene can be started immediately, so that the search can be performed more efficiently and in a short time.
