Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video recording / reproducing apparatus, and more particularly, to a video recording / reproducing apparatus for displaying a table of contents screen of a recorded program and facilitating cueing.

[0002]

2. Description of the Related Art As an example of a conventional technique similar to such an apparatus, there is a representative screen display system described in Japanese Patent Laid-Open No. 63-58690, a multi-search system described in Japanese Patent Laid-Open No. 190087/1989.

In Japanese Patent Laid-Open No. 63-58690, when a cue signal of an index pilot signal recorded in a storage medium is detected, reduced image data and position data on the recording medium are displayed on a screen and stored in an image memory. The position information is also displayed on the reduced screen.
The detection of the index pilot signal is performed when the high speed search is selected when the tape is inserted. When the index pilot signal is detected during high-speed reproduction, normal reproduction is performed, and when the normal reproduction state is stable, the reduced image is taken into the field memory. The counter value at the time of switching from high speed reproduction to normal reproduction is written in the memory as index data. By repeating the above operation, the reduced screens of the recorded programs are sequentially displayed on the screen, and the reduced screen and the tape position of the program to be selected can be easily understood and the beginning can be easily found.

In Japanese Patent Laid-Open No. 1-21075, for example, one frame of the program is stored in the image memory each time a cue signal recorded on a control track or the like is detected while the tape is fed at high speed. The video signal is stored in the image memory and displayed in a screen-reduced form. Since the reduced screen captured in the image memory is displayed every time the cueing signal is detected, it is possible to know the outline of the recorded contents of the magnetic tape. In addition, in order to make the current tape position easier to understand, the search position is detected by replacing the reduced screen of the rewound program with an identification signal such as a single signal with a cue signal that is detected again when rewinding. Is displayed on the screen in an easy-to-understand manner, and the target program can be quickly searched for.

[0005]

However, in the above-mentioned prior art, at the time of recording, only the index signal is input to the recording and the portion where the recording is started, and the reduced screen information and the recording position information are not stored. After the recording is completed, the index signal is used again during playback, and the index image is used again, and when this is detected, the reduced image and position information are loaded into the memory. There is a drawback that it takes time because the user selects the desired program after the tape is run at high speed from the beginning to the end to grasp the contents without knowing what it is.

[0006]

In order to solve the above problems, the contents of the tape are displayed by recording the table of contents information or the like at a portion such as the tail of the recorded program and reading the information when the tape is inserted. The following means are provided to facilitate program selection.

(1) A part of the program recorded at the time of recording is
Means for storing as a reduced still image of / n. (2) A means for storing table of contents information such as the position where recording is started. (3) A means for writing and reading 1 / n reduced screens and table of contents information of all recorded programs on the tape. (4) Means for generating a signal for displaying the table of contents information. (5) A means for driving the tape to the tape position where the still image information or the table of contents information is written or read.

[0008]

In the video recording / reproducing apparatus having the above-mentioned structure, the means for storing a part of the program to be recorded at the time of recording as a 1 / n reduced screen stores an arbitrary part of the program to be recorded as a still image and stores it as program information. The means for storing the index information such as the position where the recording is started stores the index information at the time when the recording is started. Here, the table-of-contents information refers to information about what kind of program is recorded at which position on the magnetic tape. For example, when a program or the like is recorded, it indicates information about the program such as the recorded date, day of the week, program name, channel number, etc., or information about the position where the program is recorded on the tape. .

The means for writing / reading the reduced screen data and position data of 1 / n of all the recorded programs on the tape and reading the reduced screen data and the table of contents information of all the programs recorded on the tape are collectively recorded on the tape. Writing to or reading from a part (for example, the beginning part or the end part of the recorded program). The tape driving means drives the tape at a high speed even when the tape is inserted or when the tape is ejected to a portion where a 1 / n reduced screen or table of contents information is written.

The means for displaying the table of contents information displays the contents recorded on the tape as characters on the screen based on the aforementioned table of contents information.

13, an addition circuit 14, a synchronization signal separation circuit 15, an image memory controller 16, and a screen character display circuit 17
It has a table-of-contents information reading circuit 18, a control signal detection circuit 19, a microcomputer (hereinafter, referred to as a microcomputer) 20, an operation key 21, and a tape drive circuit 22. The outline of the operation will be described below.

A head 4 mounted on a rotating cylinder 5 in contact with the magnetic tape 1 and rotating, picks up a reproduction signal from the magnetic tape 1. By switching this with the magnetic head changeover switch 9, a temporally continuous reproduction signal is obtained. Here, the magnetic head changeover switch 9 selects and switches the reproduction signal on the contact side depending on which of the two rotary heads is in contact with the magnetic tape 1. This timing is generally obtained by detecting a magnetic field generated by a magnet (not shown) attached to the rotary cylinder 5 with a sensor (not shown). The reproduction signal thus obtained is converted by the signal processing circuit 10,
It is output as an RF signal or a baseband video signal.

When the tape is inserted, the microcomputer 2
0 instructs the tape drive circuit 22 to rewind the tape to the nearest portion where the table of contents information is stored. The tape drive circuit 22 drives the motor 8 to rewind the tape to the nearest portion where the table of contents information is recorded. A control signal is struck in the part where the table of contents information is recorded,
Determine that it is table of contents information. The control signal read by the control pulse head 6 is detected by the control signal detection circuit 19, and the detection signal is supplied to the microcomputer 20. When the detection signal is input, the microcomputer 20 puts the table-of-contents information reading circuit 18 into the reproduction state, and 1 / n of the reduced screen information and the table-of-contents information of all the programs recorded on the insertion tape, which are pre-written at the time of recording. Is read from the magnetic tape 1.

The 1 / n reduced screen information read from the magnetic tape 1 is subjected to video signal processing in the video processing circuit 10 and then supplied to the A / D converter 11 and the sync separation circuit 15. The video signal sent to the A / D converter 11 is
Converted to digital signal. On the other hand, the sync separation circuit 15
Then, the sync signal is separated from the video signal and supplied to the memory controller 16. The memory controller 16 fetches the signal converted into a digital signal by the A / D converter 11 into the image memory 12 based on the synchronization signal. The digital signal of the reduced screen of 1 / n of the program taken in the image memory 12 is read out by the control of the memory controller 16 and supplied to the D / A converter 13. The D / A converter 13 converts the digital signal into an analog signal again and supplies it to the adding circuit 14.

Loading of the reduced screen information of each program into the image memory 12 is executed by the memory controller 16 changing the memory address according to an instruction from the microcomputer 20.

The image memory 12 does not need to have the capacity for one field in the reduced screen of one program, but can be stored in three screens of one screen.
It has a memory capacity of about 1/4 to 1/4 for several programs. Further, the reduced screen information is read from the magnetic tape 1, and at the same time, the table of contents information is also the table of contents information reading circuit 1.
Read at 8. As described above, the table-of-contents information contains information about the program and what position the program is recorded at which position on the tape. For example, when a program or the like is recorded, information regarding the program such as the recorded date, day of the week, program name, channel number, etc., and information regarding the position where the program is recorded on the tape are recorded. Has been done. The table of contents information read by the table of contents information reading circuit 18 is managed by the microcomputer 20.

Further, the control signal detection circuit 19
Detects a cue signal recorded every time a program is recorded on the tape. Information on the cueing signal detected by the control signal detection circuit 19 is sent to the microcomputer 20. The microcomputer 20 issues a control command for advancing, rewinding, or stopping the tape while searching for a target program from the table of contents information and the cue signal based on the command from the operation key 21.

The microcomputer 20 sends information to be displayed on the screen to the screen character display circuit 17. Based on this information, the screen character display circuit 17 generates a signal to be displayed on the screen and supplies it to the addition circuit 14. The adder circuit 14
Then, the analog signal from the D / A converter 11 and the signal from the screen character display circuit 17 are added. The added signal is output as a video signal.

On the other hand, at the time of recording, the recorded video signal is
The video signal supplied to the video signal processing circuit 10 and subjected to the signal processing is supplied to the head 4 via the changeover switch 9 to be recorded on the magnetic tape 1 and also to the A / D converter 11. The signal supplied to the A / D converter 11 is converted into a digital signal and supplied to the image memory 12.
The digital signal is written to the image memory 12 by the memory controller 16. This A / D converter 1
Controlling the timing of the conversion operation at 1, or
By controlling the timing of writing to the image memory 12, 1 / n of the screen is reduced. The video signal written in the image memory becomes the reduced screen information of the program being recorded. The writing instruction to the memory controller 16 is given by the microcomputer 20. At the same time, the table-of-contents information at which position on the tape the recording is started is stored and managed in the storage means inside the microcomputer 20.

After the recording is completed, the reduced screen information and the table of contents information obtained when the tape is inserted are added to the reduced screen information and the table of contents information of the program recorded this time to update the reduced screen information and the table of contents information. That is, when the tape ejection operation by the operation key 21 after the recording is accepted, the microcomputer 20 updates the reduced screen information stored in the image memory 12 and the table-of-contents information stored in the microcomputer 20 on the magnetic tape 1. Therefore, the tape drive circuit 22 drives the motor 8 to run the tape to the end position of the last recorded program.

When the end position of the last recorded program is detected, the program stops, and the updated reduced screen information and table of contents information are written therein. Eject the tape after writing.

The above tape operation will be described with reference to FIG. FIG. 2 is a schematic diagram of the magnetic tape 1 on which an image is recorded. A control and a rack are provided on the upper part, and a recording track is provided on the stock. The programs are recorded in the portions A and B of the tape 1, respectively.
The reduced screen information of the program A and the table of contents information of the program A are recorded in the shaded area A after the program A is finished. Similarly, program B
In the shaded area AB after the completion of the above, the reduced screen information of the programs A and B and the table of contents information of the programs A and B are recorded.

For example, when the tape is ejected after the recording of the program B and the tape is inserted again, the tape is rewound by the shaded portion AB at the end of the program B, and then the reduction recorded in the table of contents information portion is performed. The screen information and the table of contents information are read and stored in the storage means inside the microcomputer 20. This rewinding is performed by detecting the control and rack index end position control signal and the index start position control signal by the control signal detection circuit 19. After detecting the end position control signal of the table of contents information, if there is no program recording start cue signal after that, or if there is no image signal of the recorded program following that, the tape is stopped. Further, when the program is to be recorded after this, the program recording start cue signal of the program C is driven into the control track following the index information end position control signal to start recording. After the recording of program C is completed,
Recording end point of program C when tape is ejected (hatched area ABC)
Then, the reduced screen information and the table of contents information updated by adding the reduced screen information and the table of contents information of the program C are written, and then the tape is ejected.

An operation example in the case of sequentially recording a program from the beginning of the tape will be described with reference to the flowchart of FIG. When recording the program A, a cue signal is recorded on the control track (step S1), and then the program A is recorded. When the recording of the program A is completed, the table of contents information start position signal is recorded on the control and the rack, and then the table of contents information A including the reduced image information and the position information of the program A is recorded on the recording track, and then the table of contents information end position is recorded. The signal is recorded on the control track (step S2).
Next, in recording the program B, after the index information end position signal of the program A, a cue signal of the program B is recorded on the control track (step S3), and then the program B is recorded. When the recording of the program B is completed, the table of contents information start position signal is recorded on the control and the rack, and then the table of contents information A + B including the reduced image information and the position information of the program A + B is recorded on the recording track, and then the table of contents information end position is recorded. The signal is recorded on the control track (step S4). After that, when recording program C, program B
After the index information end position signal of, the beginning signal of the program C is recorded on the control track (step S5),
Record program C. When the recording of the program C is completed, the table of contents information start position signal is recorded on the control and the rack, and then the table of contents information A + B + C including the reduced image information and the position information of the program A + B + C is recorded on the recording track, and then the table of contents information end position is recorded. The signal is recorded on the control track (step S6), and the recording of the program ends. Hereinafter, the same operation is performed.

Next, with reference to FIG. 4, an operation example in the case where the tape on which the program is recorded is once taken out and then the tape is inserted again to newly record the program will be described. First, the program B and the contents information of the program A are recorded on the tape on which the program B is recorded.
Is being recorded (step S11), recording of the program B is ended (step S12), and when an operation signal for tape ejection is input (step S13), control after the point where the recording of the program B is ended. The index information start position signal is recorded on the track, the index information of the programs A + B is recorded on the image track, and the index information end position signal is recorded on the control track (step S14). Then, the tape is ejected from the recording / reproducing apparatus (step S15).

Thereafter, when recording the program C, this tape is inserted into the apparatus (step S16). The tape is fed in the forward direction from the position where the tape was inserted to check for the presence of a video signal (step S17). When the video signal is not detected, the tape is fed in the rewinding direction to search the control track for the index information start position signal (step S18). When the table of contents information start position signal is searched, the tape rewinding operation is stopped (step S1).
9). Then, reproduction is started in the forward direction, the table-of-contents information is read from the image track, and the reduced image information is stored in the image memory 12.
And the other table-of-contents information is stored in the storage means in the microcomputer 20 (step S20).
When the table information end position signal is detected from the control track, the tape reproducing operation is stopped (step S2).
1). Next, after the contents information end position signal, the program C
The recording start cue signal is input, and recording of the program C on the image track is started (step S29).

When the video signal is detected in step S17, the tape is fast forwarded to retrieve the index information start position signal of the control track (step S22). When the end of the tape is detected during the search, the search is stopped and the tape is rewound to the tape insertion position (step S28), and then the recording of the program C is started (step S29). If the table-of-contents information start position signal is detected before the end of the tape is detected, fast-forwarding of the tape is stopped (step S24), then reproduction is started in the forward direction, the table-of-contents information A + B is read from the image track, and reduced. The image information is recorded in the image memory 12 and other table-of-contents information is stored in the storage means in the microcomputer 20 (step S25). When the index information end position signal is detected from the control track, the tape reproducing operation is stopped (step S26). Next, the tape is played back to check whether or not there is a video signal (step S27). When no video signal is detected, a recording start cueing signal for the program C is driven after the table-of-contents information end position signal to start recording the program C on the image track (step S2).
9). When the video signal is detected, the process returns to step S22 to search for the next index information start position signal.

When the recording of the program C is completed and there is support for ejecting the tape, a table of contents information start position signal is recorded on the control track after the point where the recording of the program C is completed, and the program A +
While recording the B + B table of contents information on the image track,
The table-of-contents information end position signal is recorded on the control track (step S30). Then, the tape is ejected from the recording / reproducing apparatus (step S31), and the recording operation is completed.

FIG. 5 shows an example in which the signal passed through the present invention is displayed on the screen of the television receiver 23. On the screen, a list of tape table of contents information created by the table of contents information is displayed, and the image of the reduced screen information that has passed through the image memory is displayed on a part of the screen. In addition, the table of contents information indicates which part of the tape the current position is. In the case of FIG. 3, a black arrow is displayed next to the second program. At this time, the reduced screen displays reduced screen information of the second program. For example, when the fourth program is to be cued, the operation key 21 in FIG. 1 is operated to cued the fourth program. At this time, when the fourth program is selected, the reduced screen displays reduced screen information of the fourth program. When the fourth program is selected, the microcomputer 20 runs the tape at a high speed toward the target program. The black arrow indicating the current position of the tape on the table of contents moves to the next table of contents every time the cue signal of the next program is detected. When the cue signal of the target program is detected, the high-speed running of the tape is stopped, and standard playback or stop is performed.

The tape list table of contents information of this example is tape 1
After inserting the, the table of contents information attached to the last program recorded by the restricted traveling is read out, and the microcomputer 2
The information is stored in the internal storage means 0, and the reduced / increased information stored in the table of contents information is stored in the image lump 12 and then taken out as a video signal.

FIG. 6 shows another example in which the signal passed through the present invention is displayed on the screen of the television receiver 23. In this example, a plurality of pieces of reduced screen information are displayed at several places on the screen. Contents information is also displayed at the same time. Also in this case, by selecting the target program with the operation keys 21,
The microcomputer 20 runs the tape at a high speed toward a target program, and when the cue signal of the target program is detected, the high-speed running of the tape is stopped, and standard playback or stop is performed.

Further, the image memory 12 is used not only for displaying the reduced screen information but also for temporarily storing the image information during the search of the target program and sequentially reading out the image information, so that the high speed search or the normal reproduction is performed. It can be used to view the contents of a program at several times the speed. That is, the signal processed by the video signal processing circuit 10 during the program search at high speed is A / D
It is converted into a digital signal by the converter 11 and supplied to the image memory 12, and at the same time, the signal generated by the signal processing circuit 10 is supplied to the synchronization signal separation circuit 15. The signal supplied to the sync signal separation circuit 15 is separated from the sync signal here and is supplied to the memory controller 16.
The memory controller 16 controls the write clock and the read clock in the image memory in accordance with the cycle of the synchronization signal that changes during high-speed reproduction, which is tens or hundreds of times higher. The video signal converted into the digital signal by the A / D conversion described above by the write clock controlled by the memory controller 16 is written in the image memory 12,
Then, the digital signal written in the image memory 10 is read by the read clock controlled by the memory controller 16.

Here, the write clock and the read clock will be described. In the standard reproduction, the write and read clocks are the same, but in the case of fast-forward, the write clock is slow, and in the case of rewind, the write clock is fast. The read clock is always the same clock as in standard reproduction. The writing clock is controlled by speed information from the microcomputer 20. The image memory 12 does not need to have a capacity for one field, and may have a capacity of a part of the screen, for example, about one third to one quarter of the screen. The digital signal read from the image memory 12 is D /
By being supplied to the A converter 13 and being displayed as a video signal on the screen of the receiver, a high-speed playback image of the program being searched can be displayed instead of the reduced screen information. In the case of FIG. 3 using this method, the lower right screen displays reduced screen information during program selection, but displays a high-speed playback image during search. In the case of FIG. 4, when the program under search is reached, the reduced screen information of the program becomes a high-speed playback image, and the other reduced screen information is displayed.

As described above, according to this embodiment, when the tape is inserted, the reduced screen information and the table of contents information written on the tape are read to display the contents of the tape and facilitate the selection of the program. be able to. Further, when the tape is ejected after recording the program, the main body side does not have a storage medium such as a semiconductor memory such as a ROM or a RAM or a disk for storing the reduced screen information and the table-of-contents information on the tape so as to store the information. Complete. Furthermore, since a high-speed playback image can be viewed while searching for a program, the content of the program can be easily grasped.

FIG. 7 is a block diagram for explaining another embodiment of the video recording / reproducing apparatus according to the present invention. The feature of this embodiment resides in that the image memory 12 is not used as compared with the first embodiment shown in FIG. 1. By removing the image memory 12, the A / Ds provided before and after the image memory 12 are removed. Converter 1
1 and the D / A converter 13, the sync separation circuit 15, and the memory controller 16 are characteristic.

As described above, the signal extracted from the rotary magnetic head 4 and converted by the signal processing circuit 10 is supplied to the adding circuit 14. In the adding circuit 14, the signal from the signal processing circuit 10 and the signal from the screen character display circuit 17 are added to generate a video signal, which is supplied to a television receiver (not shown).

As described above, the table-of-contents information reading circuit 18 reads out the table-of-contents information written on the tape and supplies the information to the microcomputer 20, and the microcomputer 20 uses the information to select the desired program from the operation key 21. The tape running control is performed according to the operation of. In addition, the screen character display circuit 17
Is supplied with the tape table of contents information from the microcomputer 20 and generates a signal for displaying the table of contents information on the screen. A signal for displaying the table of contents information on this screen is supplied to the adding circuit 14. As described in the first embodiment, the table-of-contents information reading circuit 18
Sends the table of contents information read from tape 1 to the microcomputer 20. Further, in the case of recording, the table of contents information is updated on the microcomputer 20 and the table of contents information on the tape 1 is also updated through the table of contents information reading circuit 18. Further, the control signal detection circuit 19 sends a detection signal to the microcomputer 20 each time it detects a cue signal of a program recorded on the tape.

When the tape eject operation by the operation key 21 is accepted after the recording is completed, the microcomputer 20 causes the microcomputer 20 to
In order to update the internally stored table-of-contents information on the magnetic tape 1, the tape drive circuit 22 drives the motor 8 to drive the tape to the end position of the last recorded program.

When the end position of the last recorded program is detected, the program stops and the updated reduced screen information and table of contents information are written in the table of contents information recording portion of the tape 1. After writing this information, eject the tape.

The above tape operation will be described with reference to FIG. FIG. 2 is a schematic diagram of the magnetic tape 1 on which an image is recorded. The program A and the program B are recorded in the portions A and B of the tape 1, respectively. In the shaded area A at the end of the program A, reduced screen information and table of contents information of the program A are recorded. In the shaded area AB at the end of program B, program A
The reduced screen information and the table of contents information of the program B and the reduced screen information and the table of contents information of the program B are recorded.

For example, when the tape is ejected after the recording of the program of the program B and the tape is inserted again, the reduced screen information and the table of contents information recorded in the shaded area AB at the end of the program B are rewound and read. . If there is no signal recorded after the end position of the table of contents information is detected, the tape is stopped. At the time of recording, the start point of the program C is entered after the end point of the table-of-contents information of the program B to start recording. After the recording of the program C is finished, the tape is ejected after the updated reduced screen information and the table of contents information are written in the shaded area ABC at the recording end point of the program C when the tape is ejected.

As described above, according to this embodiment,
The contents of the tape can be displayed by reading the table of contents information written on the tape when the tape is inserted.
The program can be easily selected. Further, by writing the table-of-contents information to the tape at the time of ejecting the tape after recording the program, it is not necessary to have a semiconductor memory such as ROM or RAM or a storage medium such as a disk on the main body side.

As described above, in the description of the embodiment of the present invention,
Although the method of recording the table-of-contents information in the last part of the program each time the program is recorded is shown, for example, a certain capacity area for recording the table-of-contents information is secured in the beginning part of the tape and the recording of the program is completed. Run the rear tape to the table of contents information recording area,
After updating to the latest table of contents information, it is possible to return to the program recording end point again.

In this case, when continuously recording a program, the table of contents information is not updated each time, and the table of contents information is stored in the VTR main body until the tape ejection instruction is input. Needless to say, the tape may be ejected after writing the index information in the index information recording area when there is an instruction to eject the tape and returning to the program end point again.
