Abstract

PURPOSE:To allow lots of parties to use diversified information by demodulating a data signal from a television broadcast from the information receiver side and inputting the demodulation signal to a personal computer in a prescribed form. CONSTITUTION:An information sender side modulates an information data signal and sends the result while superimposing onto an audio signal (such as sub audio signal) of a television broadcast (on a prescribed channel). The receiving side receiving the information demodulates the audio signal from a television receiver 1 or a data signal via a telephone line 2, converts the demodulated signal into a digital signal of a prescribed form and the result is inputted to a personal computer 4. Thus, the information is displayed by applying display processing, for example, the input signal by the personal computer 4. Thus, the information sender side sends same information (same data) to lots of unspecified parties (personal computers).

[Technical background of the invention and its problems] In recent years, as the information society has become known, communication of various types of information (data communication) has been actively carried out. For example, communication by personal computers has become commonplace using telephone lines. Now you can easily do it at home. By the way, when transmitting information to many parties (personal computers), it is necessary to perform data communication for each party, and the burden on the information transmitting side increases as the number of parties to which the information is transmitted increases. For example, when reserving a train ticket, a designated center sends a list of train information, and the customer selects an available train while looking at the information on this list.
Information on this selected train will be sent to the reservation center above. In this case, there is a large amount of information coming from the predetermined center (commonly called downlink information), and conversely, information from the personal computer (commonly called uplink information).
There are very few. In this way, since the amount of downstream information is extremely large, when sending the same information to different customers (personal computers), the center must send the same information (same data) to each customer. It is clear that the number of users of personal computers will increase in the future, and the burden of communication is expected to increase further. This invention was made in view of the above-mentioned problems, and its objective is to provide a data communication system using television audio that can reduce the burden on the information transmitting side and make various information available to a larger number of parties. It's about doing. [Means for Solving the Problems] In order to achieve the objective of Kamikita, the present invention provides that the information transmitting side modulates a data signal of predetermined information and transmits the modulated data signal on the R1 voice signal of the television broadcast, and transmits the information. The receiving side demodulates the data signal, which is either a voice signal from the audio terminal of the TV receiver that received the TV broadcast or a signal via the telephone line, and inputs this demodulated signal into a personal computer in a predetermined format. The gist of the present invention is to enable the personal computer to receive the data, modulate the digital signal from the personal computer, and transmit the modulated signal via the telephone line.

[Function] With the above method, the information transmitting side modulates the data signal of the information and broadcasts it on the television broadcast (predetermined channel).
For example, send it as a sub-audio). The information receiving side demodulates the audio signal from the television receiver or the data signal via the telephone line, converts the demodulated signal into a digital signal in a predetermined format, and inputs it to the personal computer. Then, on a personal computer, for example, by displaying and processing the human input signal,
” can display the following information. In this way, since the information transmitting side can send the same information (same data) to an unspecified number of parties (personal computers) rather than to each party (personal computer), the data transmission {,t can reduce the burden of
Moreover, even if the number increases, the burden will not increase. Furthermore, on the information receiving side, the signal from the personal computer can be modulated and this modulated signal can be transmitted via the same telephone line, so data communication using a normal @phone line is also possible. [Example] Hereinafter, an example of the present invention will be described based on the drawings.
