Abstract

PURPOSE:To obtain information such as voice corresponding to still information obtained from digital information at the same time, by recording analog information corresponding to the digital information alternately and serially with a tape mark inserted between both the information. CONSTITUTION:First, the tape mark 2 discriminating a section between information is recorded and the digital information 3 such as a picture is recorded. In succession to this digital information 3, the similar tape mark 2 is recorded and the information 3 and the corresponding analog information 4 are recorded alternately and serially. In reading out each information, first the tape mark 2 is detected, the succeeding digital information 3 is fetched to a memory, and it is finished by waiting for the detection of the next tape mark 2 and the succeeding analog information 4 is read out and reproduced. Thus, the still picture information obtained from the digital information and the corresponding information such as voice are obtained at the same time.

Description

[Detailed Description of the Invention] This invention is an information system that records digital information such as a still image Iji and information such as audio corresponding to this on the same recording medium.
4 Regarding the recording method.

Use a cassette tape, etc. to record the static state as a digital 1# record, and whisper this as appropriate.
Efforts are being made to reproduce the 1ii1 image on cathode ray tubes and the like.

However, the image information obtained in this way does not include any sound, and for this reason, it has traditionally been difficult to add sound to such images. However, it is technically difficult to mix single voice information into such digital information, and it has not been realized at present.

This invention is based on the above-mentioned circumstances 6C'l! It was done after I saw it.

It is an object of the present invention to provide a 1' information recording system that allows the simultaneous acquisition of digital information such as digital information and corresponding f# information such as audio.

Hereinafter, one example of this invention will be explained according to the first aspect.

FIG. 1 shows the present invention applied to a magnetic tape as a recording medium. In this case, the same -J on the magnetic tape 1
c! J) Only the rack, or l track, is used. First, tape mark 2 is recorded to identify the break of t# information, and then tape mark 2 is recorded, and then tape mark I! ! Record exclusive digital 1#nobu3. Here, the digital information used is one modulated into an alternating current potential (current) in the audio domain.

Further, following this digital information 3, a tape mark 2 of ``:'' is recorded in the same manner as described above, and then information such as audio corresponding to the L digital information 3 is recorded as, for example, analog @4.

Hereinafter, in order to similarly read out each f# information from digital information 3 and corresponding 'analog information 1 with tape mark 2 intervening, tape mark 2 is first detected, and then the following digital information is read out. 3 into memory and the next tape mark 2.

After waiting for detection, the capture is completed, and the analog information 4 following this tape mark 2 is read out and reproduced. As a result, image information is displayed on a cathode ray tube or the like, and audio information corresponding to this image is simultaneously reproduced. Then, after waiting for the detection of tape mark 2 following analog information 4,
The display of positive news and the playback of the loaf/voice information are ended.

Thereafter, in the same manner, digital information 3 such as art circles and analog information 4 such as audio corresponding thereto are sequentially displayed and reproduced along the channel 7''l.

In this case, for example, each time tape mark 2 is detected, a counter is incremented, and if the start is started from tape mark 2, which matches the preset counter, arbitrary image information and audio information corresponding to this can be obtained. You can also choose.

Therefore, in this way, by recording digital information such as images and corresponding analog information such as audio on the same magnetic tape, it is possible to prevent the image information from being corrupted by the digital information, and to deal with this. Information such as tS can be obtained at the same time. This allows, for example, to display a still image of a product on a TV screen and play a corresponding audio explanation, such as a catalog collection of product introductions, or a language learning teaching material that is displayed as a still image on the TV screen and an explanation of its contents. It can be used in many ways such as 88g learning IIL + LK where it is played back as audio.

Next, FIG. 2 shows another example of an actual gun according to the present invention.

In this case, in Figure @2, different recording tracks, ie, two tracks, of the magnetic tape are used. first.

Digital information such as images is stored on one track of the magnetic tape 11 12. On the other track B, analog news reports 1-3 are recorded in parallel as audio and other information.

Also, tape mark 1 is placed at the beginning of each information 1213.
4. An end mark 15 is introduced at the end.

Here, if there is a difference in fS information stitching between the digital information 12 and the corresponding analog information 13, the positions of the tape mark 14 and the end mark 15 on the track AH do not necessarily match. Also.

What 1f is between end mark 15 and tape mark 14?
Not a single report has been entered.

To read information from the tape 11 on which information has been recorded in this manner, first detect the tape mark 14 as a start mark on track A, reset the first counter (not shown), and then read the tape mark 14. Import the digital information 12 into the memory and also write the end mark 15.
Then, the burrowing process is completed and the counter 41 is increased by one.

Next, the tape 11 is automatically rewound, a tape mark 14 is detected on track B, a counter of fX2 (not shown) is reset, and the analog information following this tape mark 14 is reproduced as audio.

Detection of the end mark 15 ends at a point. In this case, audio reproduction is performed in a state where the first and second counters match, and at the same time image information is displayed on the cathode ray tube.

Thereafter, digital information 12 such as images and T' analog information 13 such as one voice are sequentially displayed and reproduced over the tape 11 in the same manner.

In this case as well, each time the tape mark 14 is detected, the first counter is incremented and the preset counter is set to start from the tape mark 14, which is -i, so that one of the image information and the audio information can be arbitrarily selected. I can do it.

Therefore, even if this method is used, the same effect as described above can be obtained at lA.
I can be a samurai.

Next, FIG. 3 shows another practical example of this invention. Here, in FIG. 3, two tracks of magnetic tape are used as in @2. in this case.

Digital information 22 is placed on one track of the magnetic tape 21.
．． The synchronization signal information 23 is recorded in parallel on another track B, and a tape mark 2 is placed at the beginning of each information @ 2223.
4. An end mark 25 is written at the end. At this time, it is assumed that the 1# signal of the synchronization signal information 23 is taken in accordance with the information 1 of the digital information 22. and tape mark 24. The end mark 25 goes around between tracks λB.

Next, in order to read information from the tape 21 on which information has been recorded in this manner, the tape mark 24 is detected as a start mark on track A, the counter #Il (not shown) is reset, and then the tape mark 24 is read out. The digital information 22 is loaded into the memory, and the loading is finished with an end mark 25, and the above-mentioned it counter is incremented by one.

Next, the tape 21 is automatically rewound and the tape mark 24 is detected on the track uH, and the portion following the second glue 24 (not shown) is reproduced as a synchronizing signal, and the detection of the end mark 25 is terminated. In this case, the regeneration is the first and second
This is done with a foreshadowing line in which the counters match, and at the same time, this digital information is displayed on the cathode ray tube.

Below, digital information 22 and synchronization signal information 2 will be explained in the same manner.
3 are sequentially displayed and reproduced along the tape 22.

In this case as well, by incrementing the first counter each time the tape mark 24 is detected and starting from the tape mark 24 that matches the preset counter, it is possible to arbitrarily select one piece of information.

Therefore, even if this is done, the same kind of childishness as described above can be expected.

Next, Figure @4 shows a further different embodiment of this invention. In this convention, 4 tracks of magnetic tape were used, and the digital 11 # can 32. Synchronization signal information 33. for track B. GT analog information such as audio on track C 34. Second analog information 35 such as audio different from that described above is recorded in parallel on track D.

Each love @ 32, 33, 34, tape mark 36 outside the beginning of 35. An end mark 37 is inserted at the end.

In this way, for one digital information 32, in addition to the synchronization signal information 33, the first and 42nd analog information 3435 can be selectively used for journal entry.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and can be implemented with appropriate modifications within the scope of the invention.

For example, in FIG. 1 described above, one track of the magnetic tape is f, and in FIGS. 2 and 3, two tracks of the magnetic tape are f.
However, in this case, 1 or 2 tracks are used on the outgoing path of the magnetic tape, and 1 or 2 tracks are used on the 1st path (it is also possible to do so. Also, in the above, the magnetic tape is Tag.

It can also be applied to other recording media such as magnetic cards and optical discs.
