Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an audio information signal transmitting device suitable for broadcasting weather forecasts, road information announcements, etc.

[Conventional technology]

TV weather forecasts are either broadcast directly by an announcer or recorded on magnetic tape.

If the content does not change, it is broadcast repeatedly on magnetic tape.

[The problem that the invention attempts to solve]

Weather forecasts change every moment, so when broadcasting with audio or audio and images, the announcer must directly write the manuscript. It was necessary to read it or create a quick tape for broadcast. As a result, it became necessary to have people on standby for weather forecast announcements, especially at night and early in the morning, resulting in high labor costs.

In order to reduce labor costs, is it possible to forecast the weather using only images instead of audio during night and early morning broadcasts? Although it may be broadcast, it is extremely inconvenient for viewers, and there are many requests for audio transmission.

In order to solve the above-mentioned problem, assumed weather forecasts are recorded in advance on a large number of S tapes.

Select the magnetic tape that matches the weather forecast.

It is conceivable to play back the weather forecast, but there are many types of weather forecasts that can be expected, and a large number of magnetic tapes must be prepared for this purpose.

I just mentioned the weather forecast, but road information announcements,
A similar problem exists in automatic reception of arrival and departure information announcements at stations, airports, etc.

SUMMARY OF THE INVENTION An object of the present invention is to provide an audio signal transmitting device that can quickly and easily transmit desired audio information signals.

[Question A'? Means to solve]

A non-invention for solving the above problem Aw and for violating the above object is that, for example, a disc + 11 A plurality of recording media such as +21 and +31, multiple playback machines provided corresponding to the plurality of recording media, and output of the plurality of playback machines are mixed and output as a desired audio information signal block. a mixing circuit; and an input device for providing a water input to a plurality of passages selected from the plurality of passages and power distribution of the selected plurality of passages so as to obtain the desired audio information signal block from the mixing circuit; and a control circuit for controlling the plurality of playback devices so that the plurality of playback devices share the playback of the plurality of phrases specified by the input device. Note that 1) the mixing circuit of the present invention does not include the one that outputs the outputs of the plurality of reproducing machines with some overlap described in 7); It also means those that are sent out sequentially.

[For production]

In the present invention, is it possible to detect a single sentence without recording it on a recording medium? It is recorded.

For this purpose, various sentences can be created by arbitrarily arranging the clauses.
can be made. When combining two phrases to create a desired audio information signal, the joint between the phrases becomes a problem. If you search for the desired phrase χ by a single playback function,
-If the combination is ze, the time required for search will be between clauses,
The seam becomes bad.

In this invention, multiple recording media with the same content are prepared.

Selectively extract phrases from each recording medium. Therefore, it becomes possible to search for the next phrase to be assigned during the non-assignment period of reproduction, and it is possible to obtain a sound information signal without any unnaturalness.

〔Example〕

Next, referring to the embodiment of the present invention, a weather forecast broadcasting device Y*1 (2) for TV broadcasting will be explained based on FIGS.

This weather forecast broadcasting device uses an optical disc (II) shown in Figure 1 as a recording medium.

9゜）rff is sometimes recorded as cloudy. That is.

For example, 530 phrases are randomly recorded using the relationship between the seven dress signals (frame numbers) and phrases in FIG. 2. However, in order to make it easier to select a single clause, similar clauses such as ``Yamaguchi-kei Acho wa Ko'' and ``Oita-kei Acho wa Jr. Okayama Prefecture Acho wa'' are arranged as 1.

C-(7)! When making chair 111, I recorded the announcer's real voice on a tape, broke it down into necessary phrases, and used VCVTR tape to arrange it as shown in Figure 2. This FL'2 motherboard is recorded on a disc (11).The disc (11) is a recordable laser video disc.

It has a built-in buffer memory (not shown) for storing data.

Address memo U (151 contains address signals corresponding to each clause shown in FIG.
The address 0 frames before (hereinafter referred to as the hash address) is written as 1. In this example, the position of this path address varies somewhat depending on the content of the clause, but the position of the path address may be determined by the number of frames. If you want to set the path address to a certain number of frames, select the path address?
Write in Memo+7051 and enter the final address or error? Calculate the number of frames and settle. This path address is used for control to improve the continuity of phrases.

The antenna is installed next at 11. Although not shown, a monitor circuit is also provided.

In this example, in order to send out a video signal in synchronization with audio information, a background video signal generation circuit (c) 1 is used.
A text information memo IJ+241 is provided.

Background video signal generation circuit C): 31 consists of a VTR that sends out a TV signal suitable for weather forecast broadcasting in synchronization with the start signal given from the control circuit (71). Text information memo IJC) 41 is , the character information shown in the character column example in FIG. 2 is written 1t''.

Character information is sent out in response to character index signals V, , V2, . . . given by the control circuit (7). This memory t241 is connected to an NTSC conversion circuit (c) for superimposition. What is the output of the background video signal generation circuit and the output of the NTS (4 = switching circuit) that generates the superimpose signal?

Be mixed with the mixed circuit name. The output stage of the mixing circuit (c) includes an amplifier (3), a modulator, an amplifier, and a diplexer.
, and antenna so are sequentially provided.

Next, the operating method and operation of this weather forecast broadcasting system will be explained. If the weather forecast content (desired audio information signal block) is "For the Yamaguchi region, southwest winds will be strong for a time -? f strong, sunny and sometimes cloudy," then the index signal will be sent by the input device field. (setting signals) are input sequentially. In other words, look at the TS passage displayed on the display and find the necessary phrase y! - Sequentially select and generate an index signal (setting signal) corresponding to the required phrase using a predetermined code.

In this example, index signal A1. ``Index signal A*o- indicating southwest wind
An index signal Aso that temporarily shows a slightly strong "n",
The cursor is sequentially moved to the part corresponding to the index signal A9 (l) which indicates the index signal A9 (l) from time to time.
+ Codes corresponding to Ago and A90K are generated sequentially, and address signals corresponding to these index signals are sequentially read out from the address memory a9, and the control circuit (buffer built in 7;) % IJ Write them in order. At the same time, the path address is also taken out of the memory a9, and the buffer completion memory llIC$1 is written.

Next, based on the program built in the control circuit (7), at tl of Q3J in FIG. Pickup of VC first playback machine (4), first 7 dresses of second clause W3o [050
01], the second playback a(5) pick-up, the third clause VV6. ) The positioning of the pickup of the third playback machine (61) is executed at the first address [08100].
'Lru. This means that the preparation for starting regeneration is complete.

After that, at the scheduled time (t2), the first disk +I
Playback starts from + address [01000].

The phrase W1 at (01050:]-2, ie, ``Yamaguchi-kei Ateha'' is read from the address [01000], and the audio information signal schematically shown in FIG. 4 is obtained.

The FL address signal obtained from the first player (4) during playback every rotation of the disk (1) is sent to the control circuit (71K).

Control circuit (71 checks address detection. Control circuit (7)Y constitutes the CPU, according to the program)
A time point t3'Y when the pickup passes a path address slightly earlier (8 frames earlier) than the final lower address signal [01050] of the th phrase W1 is detected.

ff1J, a path address time t3 is detected based on a comparison with the address detected from a preset path address (1). When the control circuit (71 detects the path address in the first clause W).

In response to this, the second reproducing device (5) starts reproducing the second clause W1o. In other words, as shown in Figure 4), the second phrase ``The southwest wind starts playing J'' from the address (05001) of the second disk (2). , is executed at the last address (01050]! of the first clause, so +
The playback output (audio information signal) of the first disk (1) and the playback output (audio information signal) of the second disk (2) overlap for a period of 8 frames (approximately π seconds) from 3 to t4. arise. If one phrase is combined, if the reproduction of the previous phrase is completely completed before the next phrase is started, a no-signal period will occur between the phrases, causing an unnatural auditory sensation. , the unnaturalness is eliminated by overlapping the reproduced signal near the end of the previous clause with the vicinity of the beginning of the subsequent clause, as in the example of ``Fumei''. Note that the voice level of a phrase generally decreases at the beginning and end.

Moreover, since the time width of the overlap is extremely short, there is no possibility that the sound will become unclear due to this overlap. When dt4 is determined by address detection at the end of the reproduction of the first clause W] by the playback device (4) of the [th], the first seven addresses [151]0] of the fourth @th clause W9o are The playback machine (4) begins to move and move.

This pickup movement is completed in about 2 seconds or less. In addition, when the second and third reproduction W (51 (61) is required, the pickup should be moved to the next address immediately after the first reproduction of these is completed.

The second reproduction a(5) Niu period 1 is address [05°0

5110] to (]5202]l, VCt5 to 16 (12 frames) respectively.

An overlapping period of +7 to t (10 frames) occurs.

Each playback a (41 (51 Fe2) is sent to the audio information signal mixing circuit a of the specified address. As a result,
An audio information signal block as schematically shown in FIG. 4 is obtained, making it possible to broadcast the intended weather forecast.

The control circuit (7) simultaneously controls the transmission of audio information signals.

The background video signal generation circuit 031 performs zero control for transmitting the video signal Z. Furthermore, the control circuit (7) includes 1
The character index signal shown in Fig. g2 is generated in correspondence with the voice index signal. That is, one-character index signals v, , V2O1"go, V2O are generated with predetermined codes. These character index signals vl, V3

Functions as a readout address signal for 1, and reads out data indicating ``Yamaguchi-style Atchohako'' ``Southwest wind'' ``Temporarily strong f'' and ``Sunny sometimes ``Forest''. The read data is converted to NTSC (Iil) and used for superimposition.

The method of this embodiment has the following advantages.

(1) Disk +11 +21 (A large number of phrases are written in advance on disk 31, and this method uses a method other than the weather forecast necessary for combining these phrases, so it is possible to easily send out a large number of weather forecasts with different contents. can.

(2) The first to third playback machines +41 +51 (Since the outputs of 61 are controlled so that they overlap, the unnaturalness of the seam between one phrase is eliminated.

(3) Since the memo for text information is synchronized with the audio information, weather forecast Z can provide more accurate information.

[Love form example]

The invention is not limited to the embodiments described above.

It is deformable. For example, in addition to weather forecasts on TV, the present invention can also be applied to road information announcements, departure and arrival guidance announcements at stations, airports, etc., and automatic reception guidance announcements. In addition, if the phrase is not short, 72 playback machines may be used. Further, if necessary, the number of recycled machines may be four or more. Alternatively, the input device a61 may be configured with only a keyboard or a graphic display.

In addition, buffer memo 11 Y address memo IJ (1
