  As a third effect, it is possible to eliminate those that violate public order and morals by performing an automatic check on a teletext message before distribution.

  Next, embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, a user and a general viewer are connected to a broadcasting station via the Internet network 1 to transmit / receive data information. On the broadcast station side, a server 2 that connects the user and the broadcast station, performs message conformity determination, charges addition, and stores data information received from the user, and a converter 3 that encodes the data information for transmission A modulator 4 for multiplexing the broadcast program signal and the data information and supplying the data to the transmitter 5; a transmitter 5 for transmitting radio waves; a receiver 7 for confirming transmission of data information; and a demodulator 10 In addition, a converter 8 that converts the transmitted data information into an original code and a code data comparator 9 are provided. The general viewer can receive the data information at the receiver 6. Therefore, the broadcasting station includes a server 2 that performs various processes, a converter 3 that encodes data to transmit data, a modulator 4 that multiplexes and modulates a broadcast program, and a transmitter 5. Also, the transmitting station receives the transmission wave, performs demodulation and inverse transformation, and confirms the coincidence between the transmitted data information and the received data information.

  Next, the operation of this embodiment will be described based on the flowchart shown in FIG. It is premised that the broadcasting station has established a homepage or the like for placing data information from users on television broadcasting. The user accesses the homepage of the broadcasting station via the Internet network 1, performs user registration, and acquires an ID number. After that, the user enters data information and desired broadcast time on the homepage and transmits it. The broadcast station server 2 accepts data information and desired broadcast date and time in accordance with the steps S1 to S2. In S13, when the past transmission history is browsed and the past transmitted data is retransmitted, the data to be retransmitted is selected from the already transmitted data information of the server 2. The broadcast station server 2 checks the content of the message when the data information is message information in S3, and notifies the user of the message check result and the charge display. In the case of information other than messages, this step is passed without checking.

  The message check is based on prohibited words and phrases based on the broadcasting law and words and phrases based on broadcast ethics unique to the broadcaster, and these words and phrases are stored in the server 2. When a message is input, it is compared with the reference phrase described above, and if there is an inappropriate message, an alarm message is transmitted to the user (S6). In S4, it is determined whether or not there is a vacancy at the user's desired broadcast date and time, and if it is duplicated, an alarm message is sent to the user.

  If the checks in S3 to S4 are passed, the contents of the broadcast data, the charge, the scheduled broadcast date and time, etc. are reconfirmed to the user in S5 and S7. When the scheduled broadcast date and time is reached, the encoded data information is sent from the server 2 to the converter 3, and the converter 3 encodes it into a form suitable for the modulator 4 at the next stage, and the data is sent to the modulator 4 and the comparator 9. Send it out. At this time, the comparator 9 holds the data information and prepares for confirmation after ON AIR (S8). In the modulator 4, encoded data for teletext broadcasting is multiplexed on the broadcasting program, and the multiplexed data is emitted from the transmitter 5 as radio waves. As a result, the general viewer's receiver 6 can watch the broadcast program and simultaneously view the data information. In the receiver 7, the broadcast data is received by the broadcast data and demodulated by the demodulator 10. A portion related to data information in the demodulated signal is sent to the converter 8. The converter 8 converts the received data information into the same format as the code data converted by the converter 3 and sends the data to the comparator 9. As shown in S10, the comparator 9 compares the held transmission data information with the received data information, and confirms that transmission has been completed normally.

  Finally, the transmission completion information is sent from the comparator 9 to the server 2, the transmission completion email is sent from the server 2 to the user, and a charge is added. If there is a transmission error, the transmission of data information is repeated.

  Next, the configuration of the server 2 will be described with reference to FIG. As shown in FIG. 3, a user and a general viewer connect to a broadcast station via the Internet network and access the server 2 on the broadcast station side.

  In the server 2 on the broadcasting station side, past broadcast data information is accumulated, and a user and a general viewer can freely browse. In the present embodiment, it consists of a user personal BOX that can be used only by a user by logging in with an ID, data information two days before publicly available, data information one day before, data information for today, and information by genre. It can be roughly divided into two categories. The user personal BOX is used when the user resends the message. The general viewer can use only the latter data information BOX, and can access it at any time via the Internet network.
