[0018]

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a communication protocol showing an embodiment of the information communication system according to the present invention.

First, negotiation is carried out between the transmission side terminal and the reception side terminal with the field contents "whether the transmission destination (reception side terminal) supports this system" (P
1). Then, as a result of the negotiation, when it is confirmed that the transmission destination supports this method, the transmission source ID is passed to the reception side terminal (P2). here,
The “sender ID” contains an address that enables communication with the sender, and may be received when requesting detailed information after receiving digest information described later or when a communication error or the like occurs. Helps to re-contact if not possible.

Next, the "transmission information ID" issued by the transmission source (transmission side terminal) is transferred to the reception side terminal (P3). Here, the "transmission information ID" is an identifier for identifying the transmission content, and when the detailed information is requested after receiving the digest information in combination with the "transmission source ID" described above, communication error, etc. It is useful for re-communication if something happens and you cannot receive it.

Then, the sending terminal delivers the desired "password" to the receiving terminal, and the receiving terminal checks the "password" (P4). If the "password" is not specified from the sending terminal, the receiving terminal receives all the information sent from the sending terminal, but if the "password" is specified, the "password" is entered. If the password does not match, the information is received, and if the password does not match, the information is not received.

Next, the transmission destination (reception side terminal) and the transmission source (transmission side terminal) specify and determine the "communication content" (P5).
In this embodiment, it is possible to specify four types of communication contents, detailed information, digest information 1, digest information 2, and detailed information request.

Here, the detailed information refers to all the information that the transmission side terminal has, and the digest information refers to the information showing only the outline of the detailed information. Digest information 1 refers to a case where the detailed information is requested to be transmitted continuously after the digest information is transmitted within the same communication, and digest information 2 is a case where the detailed information is requested by re-communication after the communication is completed. Say.

Next, the transmission destination notifies the transmission source of "information attribute priority designation" (P6). Here, "information attribute priority designation" includes attributes such as information device type, information form, resolution capability, and bit depth from the highest priority, and these attributes are assigned in order from the highest priority. Send to the destination and select the most suitable output device, information format, resolution, etc. for data communication. However, this content is in accordance with the “communication content”, and the content can be appropriately switched between the detailed information and the digest information.

Next, the actual "data communication" is performed (P
7). That is, the information communication is performed after the process of converting to the attribute such as the selected information form and resolution.

Then, the above-mentioned "communication content" is determined (P
When the digest information 1 is not designated in 5), "communication is completed" after all the information is sent (P9).

On the other hand, if the digest information 1 is selected in the determination of "communication content" (P5), "detailed information request request / none" is confirmed, and if there is no request for the request, "communications end". On the other hand, if there is a request request, the "information attribute priority designation" is performed again, the most suitable output device / information form for communicating detailed information is selected, data communication of detailed information is performed, and "communication ends". (P9).

Further, when the digest information 2 is specified in the "communication content", if the detailed information is required, the "sender ID" stored in the previous destination by the same communication protocol is used. Based on the request communication, the stored “transmission information ID” is used as the “transmission information I” for this communication.
By specifying "D", the information content for which the digest information was received last time is identified, and the detailed information is received through the procedure of "communication content" and "information attribute priority designation".

FIG. 2 is a flow chart showing the control procedure of the above information communication system. When communication is started in step S1, it is judged in the following step S2 whether or not the receiving side terminal can perform data communication in this system. . When the reception is not possible by this method, the process proceeds to step S3, the data communication by another communication protocol is performed, and the process proceeds to step S18 to end the communication and finish the process.

On the other hand, when it is determined that the receiving side terminal is capable of data communication according to this method, the process proceeds to step S4, and the source ID, the transmission information ID, and the password are negotiated between the source and the destination. Next, in step S5, it is determined whether or not the passwords match, and if they do not match, the communication ends (step S1).
8) Finish the process.

When the passwords match, the specified communication contents are transmitted and received to and from each other, the process proceeds to step S7, and it is determined whether or not the request communication is made. Then, since the determination result of step S7 is initially negative (No), the process proceeds to step S8, and it is determined whether or not the communication by the digest information 1 is designated as the communication content. If digest information 1 is not selected, step S
In step 9, the optimum output device / information form is determined by receiving the information attribute priority designation of the transmission destination. In this case, the digest information 2 or the detailed information depends on the determination of the communication content. Then
In step S10, the data is converted and transmitted according to the data communication specifications determined in step S9, and after all the information is sent to the destination, the communication is ended (step S18) and the process is ended.

On the other hand, in step S8, the digest information 1
If it is determined that is selected, step S11
Then, the optimum output device, information form, etc. are determined based on the information attribute priority of the transmission destination, data conversion and transmission are then performed (step S12), and it is determined in step S13 whether detailed information is necessary. When the detailed information is unnecessary, the communication is ended (step S18), and the processing is ended. On the other hand, when the detailed information is necessary, the communication content is changed to the detailed information (step S14), and the communication content data conversion and Transmission is performed (step S10), communication is terminated (step S18), and the process is terminated.

In the case of request communication, the determination result of step S7 becomes affirmative (Yes) in the next loop, and it is determined whether or not the transmission information ID has an identifier for identifying the transmission content. While the communication is ended (step S18) and the processing is ended, if there is, the optimum output device / information form etc. are determined based on the information attribute priority order of the destination (step S16), and then data conversion and transmission are performed ( In step S17, the communication is ended (step S
18) Finish the process.

FIG. 3 is a conceptual diagram showing the conversion relationship of each information form.

For example, when image data reception is higher in the attribute priority of the receiving side terminal, the text data of the transmitting side terminal is converted into image data and the data is transmitted to the receiving side terminal. That is, the text data is converted into an image description language and transmitted to the receiving side terminal, and the receiving side terminal receives the text data of the transmitting side terminal as a still image such as a computer graphic or a moving image such as an animation based on its priority. Images can be displayed on the terminal. Further, by converting the still image into time information, the still image can be converted into a moving image, and data communication can be performed from the transmitting side terminal to the receiving side terminal.

With respect to the attributes of the receiving side terminal, when text data reception is at a higher level, image recognition including still image processing or moving image processing including OCR etc. is performed and then the image data is converted into text data by the data conversion side. Data communication is performed from the terminal to the receiving terminal.

Furthermore, by recognizing the voice of the voice information, the voice information can be inserted as a subtitle in a moving image or a still image.

When converting to voice data, it is possible to recognize voice, convert it to text data, and send it as text data to the receiving side terminal. When converting the text data into voice data, the text data can be voice-synthesized and transmitted as voice data to the receiving side terminal.

Furthermore, the data is a document image and a natural image.
If it consists of graphic image data, after the image area separation process, the document image and the natural image / graphic image are each compressed by the optimal hierarchical compression method, or the natural image / graphic image is optimally compressed hierarchically. It is also possible to compress the document image with OCR and convert the document image portion into OCR into text, and then send it together with the image area address information to perform expansion / image area composition on the expansion side.

As described above, according to the above information communication system, the transmitting side terminal transmits to the receiving side terminal a sufficient amount of information required by the receiving side terminal with the optimum attribute convenient for the receiving side terminal. Therefore, it is possible to avoid unnecessary transmission of communication data, reduce the communication volume as a whole, and eliminate communication traffic congestion.

The present invention is not limited to the above embodiment.

The request communication is not limited to the case of the digest information, and if the detailed information is required, it can be obtained by the same procedure as above.

In addition to this, even if attributes such as different information devices, receivable information forms, and resolutions that can be handled are mixed in the destination table, batch transmission is performed by performing communication to each destination sequentially. It can be realized and the operational efficiency of the contents of the present invention can be greatly increased.

The attributes such as the information equipment connected to the destination, the receivable information format, the resolution that can be handled, and the combination of the information equipment, the receivable information format, the resolution that the recipient desires at that time It is also possible to periodically distribute the destination table in which the priority order is described to the destinations that frequently communicate, and have a fresh destination table.

For a destination that always needs only the digest information and only the detailed information, if this is described in the destination table, the content according to the description will be obtained regardless of the information attribute priority designation of the destination. Means for enabling communication in the Internet have also been considered.

Furthermore, the conversion of the information form does not necessarily have to be limited to one form.

When transmitting in the hierarchical compression format, the transmission destination transmits up to the layer required by the transmission destination, and the reception side decompresses it.

[0049]

As described in detail above, according to the present invention, a sufficient amount of information required by the transmission destination can be transmitted in a convenient information form to the communication destination at that time, and the digest image transmission Digest text summary Sending detailed information by requesting the destination only when the destination is really needed by sending can avoid wasteful transmission of communication data, reducing the amount of communication information as a whole and communication traffic. It can greatly contribute to alleviation of congestion.
