Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic recording and reproducing device with a multi-screen heading function that allows effective use of multi-screen headings.

[Prior art] Using a control track, a search cue signal (
A magnetic tape recorded with a V I SS) is selectively reproduced while cuing up sequentially according to a cue signal, and the selectively reproduced images are reduced in display area and gathered into one sheet.
2. Description of the Related Art Magnetic recording and reproducing devices are known that are capable of displaying completed images as multi-screen headings. This type of magnetic recording and reproducing apparatus 1 shown in FIG. 3 can perform a high-speed search for a position where a cue signal is recorded by specifying a high-speed search mode, and in order to avoid commercial parts etc. at the search position, Image data after 2 minutes of standard playback is played back, for example, for about 5 seconds, and among the playback images, an image 1.5 seconds after the start of playback with no image disturbance at the start is stored. In this way, by collecting headline information about already recorded programs, a multi-screen headline that divides one screen into multiple small screens and displays them is completed, and the screen 2a of the monitor receiver 2 is displayed as necessary. It is configured so that it can be displayed.

[Problems to be Solved by the Invention] The above-mentioned conventional magnetic recording/reproducing device with a multi-screen heading display function inserts and records the multi-screen heading obtained by the high-speed search mode at the beginning of the winding of the magnetic tape. By playing this multi-screen heading, you can not only understand the recorded contents of the magnetic tape at once, but also use the automatic search function to selectively play the desired program or automatically play multiple programs with the specified playback order. It is possible.

However, after playing a program recorded in the middle of a magnetic tape, if you want to play another program and need a multi-screen heading, the multi-screen heading will only appear at the beginning of the magnetic tape. Since the magnetic tape is not recorded, the magnetic tape must be completely rewound, and if you include the tape advance to the desired program, it will take time to actually play the desired program, and the automatic search function will not work. There were problems such as a lack of consideration for users to make full use of it.

[Means for Solving the Problems] The present invention solves the above-mentioned problems, and it is possible to search a recorded magnetic tape from the beginning of the winding of the tape by attaching a search signal for each recording. The image memory includes a reproduction means for sequentially selectively reproducing images according to a signal, and an image memory for storing an image obtained by assembling a part of the images sequentially selectively reproduced by the reproduction means as a multi-screen heading. The multi-screen heading stored in the multi-screen heading is sequentially inserted and recorded in accordance with the cue signal from the end of winding of the tape after the selective playback.

[Function] This invention selectively reproduces a magnetic tape recorded with a cue signal for search each time it is recorded, sequentially from the beginning of the tape according to the cue signal, and collects a portion of the selectively reproduced images. By storing the resulting images as multi-screen headings and inserting and recording these multi-screen headings sequentially from the end of tape winding according to cue signals, multi-screen headings can be called up in response to a heading display request in the middle of playback. Reduce time.

[Example] Hereinafter, an example of the present invention will be described with reference to FIG. 1.2. FIG. 1 is a schematic configuration diagram showing an embodiment of a magnetic recording and reproducing apparatus with a multi-screen heading function of the present invention;
FIG. 2 is a flowchart for explaining the operation of the central processing unit shown in FIG.

In FIG. 1, a magnetic recording and reproducing device 11 with a multi-screen heading function includes a tape running fR111 circuit 12 that controls running of the magnetic tape according to various modes, and a pair of rotating servos that receive rotation servos synchronously linked to the tape running control circuit 12. It consists of a recording and reproducing circuit 13 having rotating magnetic heads 13a and 13b, an image memory 14 that stores multi-screen headings formed by selective reproduction in a high-speed search mode, and a central processing unit 15 that centrally controls these circuits.

The image memory 14 reduces the display area of the images sequentially selected and reproduced by the recording/reproducing circuit 13, collects them into one image, and stores the resulting image as a multi-screen heading. In the case of this embodiment, the tape running control circuit 12 and the recording/reproducing circuit 13 have a reproducing means for selectively reproducing the magnetic tape while cueing the magnetic tape in accordance with cue signals, and a multi-screen heading stored in the image memory 14. Both constitute recording means for inserting and recording according to the signal.

When recording multi-screen headings, first select the high-speed search mode as shown in step (101) in FIG. As a result, the tape running control circuit 12
operates and causes the magnetic tape to run at high speed until the first cue signal is detected.

Then, when the first cue signal is detected, step (
In step 103), the recording/reproducing circuit 13 reproduces a part of the image recorded at the search position or a position slightly distant from the search position. The images selectively reproduced at this time are stored in the image memory I4. When the storage in the image memory 14 is completed, as shown in the next step (104), the high-speed search is restarted and selective playback is repeatedly executed until the end of tape winding is detected. Then step (+10
) When the end of winding of the magnetic tape is detected, the multi-screen heading creation is completed with the tip (111).

Next, the multi-screen headings completed in this way are recorded at the beginning of each program while rewinding the magnetic tape.

First, in step (112), when the high-speed rewind mode is selected, the magnetic tape is rewound until a cue signal is detected. Then, following the cue signal detection step (113), in step (+14), the recording/reproducing circuit 13 inserts and records the multi-screen heading.

The insertion position of this multi-screen heading is made at the detection position of the cue signal, so that the multi-screen heading is inserted and recorded at the recording start position of each program.

After completing the first insertion recording in this way, step (115)
) to (120), high-speed rewinding by the tape running control circuit 12 and insertion recording by the recording/reproducing circuit 13 are repeatedly executed until the beginning of winding of the tape is detected. Finally, in step (121), a multi-screen heading is inserted and recorded at the beginning of the tape, and all operations are completed.

In this manner, the magnetic recording/reproducing device 11 with a multi-screen indexing function allows the tape running control circuit 12 and the recording/reproducing circuit 13 to cooperate with each other to record a magnetic tape with a cue signal for searching for a recorded number. By doing so, the tape is selectively reproduced sequentially according to the cue signal from the beginning of the tape, and the image obtained by collecting some of the selectively reproduced images into one image is stored in the image memory I4 as a multi-screen heading. Since the multi-screen headings are inserted and recorded sequentially from the end of the tape winding according to the cue signal, it is possible to insert multi-screen headings at different recording locations of the recorded content, thereby making it possible to record the multi-screen headings while the magnetic tape is being played back. So, even if you want to see the headline, you don't have to rewind the magnetic tape to the beginning each time, just play the multi-screen headline inserted and recorded at the position closest to it, and the headline is displayed halfway through playback. Multi-screen headings can be called up quickly on request.

[Effects of the Invention] As explained above, the present invention selectively reproduces a magnetic tape recorded with a cue signal for search each time it is recorded, sequentially from the beginning of the tape according to the cue signal, and reproduces the selectively reproduced images. The image obtained by assembling a part of the tape into one sheet is stored as a multi-screen heading, and the multi-screen heading is inserted and recorded sequentially from the end of the tape winding according to the cue signal. It is possible to insert a heading at each recording point where the recorded content is different, so even if you want to see the heading while playing the magnetic tape, you can see the heading without having to rewind the magnetic tape to the beginning of the tape each time. It is only necessary to reproduce the multi-screen heading inserted and recorded at the position closest to the starting point, and this provides excellent effects such as being able to call up the multi-screen heading in a short time in response to a request for displaying the heading in the middle of playback.
