The television transmitting apparatus shown in FIG. 6 and the television receiving apparatus shown in FIG. 7 constitute a system for transmitting and receiving a video signal, an audio signal, and a character signal.

The acoustic character signal may be any acoustic signal in accordance with a predetermined rule as long as it is a characteristic acoustic signal corresponding to the character information signal on a one-to-one basis. It is desirable that the signal is unlikely to be erroneously determined as an acoustic character signal.

Therefore, DTMF is used as the acoustic character signal.
An embodiment using a (Dual Tone Multi-Frequency) signal sequence will be described below. The DTMF signal sequence has a relatively low possibility of erroneously discriminating an audio signal that is not intentionally made to be similar to a DTMF sequence signal because the DTMF signal sequence has already been put to practical use in a telephone push line or the like. it is obvious.

FIG. 8 is a diagram showing the standard frequency of the DTMF signal. This figure shows that, for example, the sound signal representing “1” is a sound signal obtained by superimposing the sound signals of 1209 Hz and 697 Hz.

The circuit for generating the DTMF signal is a DTMF signal.
It has been made into a semiconductor integrated circuit as an F-tone encoder and has been generalized. For example, when "1" is input to the circuit, a superimposed signal of the acoustic signals of 1209 Hz and 697 Hz is generated.

A circuit for extracting a DTMF signal from an input audio signal is a semiconductor integrated circuit as a DTMF tone decoder, and is generally used. If the input audio signal of the circuit includes audio components of 1209 Hz and 697 Hz, "1" is output.

By associating such a signal sequence in which the DTMF signals are arranged in a time series with the character information signal to be transmitted, it can be used as an acoustic character signal.

Next, with reference to FIG. 9, an example of a DTMF encoder applicable to the encoder in each of the above embodiments will be described. When the character information signal is supplied to the microcomputer 902, the microcomputer 902 outputs a signal corresponding to the character information signal with reference to the character information signal DTMF signal sequence correspondence table storage device 901 and supplies the signal to the DTMF tone encoder 903. As a result, a DTMF signal sequence is output from the encoder 903.

Next, an example of a DTMF decoder applicable to the decoder in each of the above-described embodiments will be described with reference to FIG. An acoustic character signal composed of a DTMF signal sequence is DT
The signal is supplied to the MF tone decoder 1001 and converted into a signal. The signal is supplied to the microcomputer 1002, and the microcomputer 1002 refers to the character information signal DTMF signal string correspondence table storage device 1003 and outputs a character information signal corresponding to the acoustic character signal composed of the DTMF string.

The DTMF encoder shown in FIG.
The DTMF decoder shown in FIG.
A system that encodes an MF signal sequence and converts the DTMF signal sequence into an original acoustic character signal is configured.

FIG. 11 illustrates an example of a character information / acoustic character signal correspondence table in the character information transmission / reception system including the devices shown in FIGS. This table shows, for example, that the character information “A” corresponds to the DTMF signal sequence “001 @”.

That is, when the user transmits the character "A", the speaker of the transmitting apparatus transmits the character "001 @"
A TMF signal train is emitted. If the microphone of the receiving device picks up the DTMF string "001 @", "A" is displayed on the monitor.

When the user transmits the character "i", a DTM "002 @" is transmitted from the speaker of the transmitting apparatus.
An F signal train is emitted. Also, the microphone of the receiving device
If the DTMF sequence "002 $" is picked up, "I" is displayed on the monitor.

When the user transmits the character “Ai”, the DTM “003♯” is transmitted from the speaker of the transmitting device.
An F signal train is emitted. Also, the microphone of the receiving device
If the DTMF string “003♯” is picked up, “Ai” is displayed on the monitor.

As in the above example, it is not always necessary to make one character correspond to one signal, and it is also possible to make a plurality of characters correspond to one signal. Also, it is more efficient to associate one signal with character information that is frequently transmitted.

The acoustic character signal receiving device of each embodiment described above can be provided in various electronic information devices. FIG. 12 shows a case where an acoustic character signal receiving device is provided in a radio receiving device. Numeral 1201 denotes a radio receiving apparatus as a whole, and numeral 1202 denotes a receiving antenna thereof. 1203
Is an acoustic character signal receiving device provided in the radio receiving device 1201, and its receiving antenna can share the antenna 1202.

FIG. 13 shows a case where an audio character signal receiving device is provided in a video / audio signal receiving / recording / reproducing device (VTR with a television tuner). 1301 is V with TV tuner
The TR is shown as a whole, and 1302 is its receiving antenna. 1303 is a VTR 13 with this TV tuner
In the acoustic character signal receiving device provided in No. 01, the receiving antenna can share the antenna 1302.
