Next, referring to the flowchart of FIG.
The processing procedure of the information processing unit described above, that is, the processing performed by the audio URL signal input device according to the present invention will be described. In step S701, it is determined whether a URL has been input from the decoder. If a URL has been input, control proceeds to step S702, and if no URL has been input, control returns to step S701. That is,
Until the URL is input, the control remains in step S701. In step S702, the input U
The web site indicated by the RL is accessed via the network line to obtain web information, and the control moves to step S703. In step S703, web information is output, and control returns to step S704.

By using such a processing procedure, the audio URL signal input device according to the present invention, when extracting an audio URL signal from an input audio signal, immediately accesses a website indicated by the URL via a network line. And output the acquired web information.

By combining the above-described means, apparatus and processing procedure, it is possible to realize an audio URL signal input device that extracts a URL from an input audio signal and accesses a website indicated by the URL.

By using the above-described audio URL signal output device and audio URL signal input device according to the present invention,
An RL transmission system can be realized.

As the audio URL signal, any audio signal can be used as long as it is a characteristic audio signal corresponding to the URL on a one-to-one basis according to a predetermined rule, but is not an audio URL signal. Sound signal is converted to sound U
It is obvious that it is desirable that the possibility of erroneous determination as an RL signal be low.

Therefore, DTMF is used as the acoustic URL signal.
An example using a signal sequence will be described. The DTMF signal sequence is a DTMF signal that represents an audio signal that is not intentionally made similar.
The relatively low possibility of being erroneously determined as a signal sequence is clear from the fact that it has already been put to practical use in telephone push lines and the like.

FIG. 8 is a diagram showing the standard frequency of the DTMF signal. This figure shows that the acoustic signal representing “1” is 12
This indicates that the sound signal is a sound signal in which sound signals of 09 Hz and 697 Hz are superimposed. The circuit that generates the DTMF signal is integrated and generalized as a DTMF tone encoder. For example, when "1" is given as an input to the circuit, an acoustic signal in which acoustic signals of 1209 Hz and 697 Hz are superimposed is generated. Moreover, DT is calculated from the input sound signal.
The circuit for extracting the MF signal is integrated and generalized as a DTMF tone decoder. For example, when the input audio signal of the circuit includes both the audio components of 1209 Hz and 697 Hz, “1” is output.

Since the URL is usually composed of alphabets and symbols, if a method capable of expressing the alphabets and symbols by combining 16 types of codes shown in FIG. 8 is used, a signal in which the DTMF signals are arranged in a time series is used. It is clear that URLs are easy to represent in columns. For example, “a” is “0.1”, and “b” is “0.
2], alphabets and symbols can be represented by using 16 types of codes shown in FIG. 8, and the URL to be transmitted, which is a combination thereof, is a DTMF signal. Can be converted into a signal sequence arranged in time series. That is, DTMF
Since a signal sequence in which signals are arranged in time series can correspond one-to-one to a URL to be transmitted, it can be used as an acoustic URL signal.

An audio URL signal output device using a DTMF signal sequence as an audio URL signal may be obtained by making the encoder of the above audio URL signal output device correspond to the DTMF signal sequence. Similarly, an audio URL signal input device that uses a DTMF signal sequence as an audio URL signal only has to make the decoder of the above-described audio URL signal input device correspond to the DTMF signal sequence.

01 is supplied. The microcomputer 901 stores the URL / DTMF signal sequence correspondence table storage unit 90 based on the supplied control command.

Refers to the URL / DTMF signal string correspondence table storage unit 1003 based on the information supplied from the DTMF tone decoder, acquires a control instruction corresponding to the signal, and outputs the acquired control instruction as a URL from an output terminal. I do.

When these encoders and decoders are applied to an audio URL signal output device and an audio URL signal input device, respectively, a UR that converts a DTMF signal sequence into an audio URL signal can be obtained.
An L transmission system can be realized. Thus, the sound URL
It was shown that a URL transmission system using a DTMF signal sequence as a signal can be realized.
