Description

[Detailed description of the invention]

The present invention relates to a composite information communication processing method for transmitting or receiving composite information in which different types of information such as text, images, and audio are mixed in an information communication device. Currently, voice information is transmitted using a telephone as an analog signal in the 4KHz band, and character image information is transmitted using various data terminals and facsimile devices at 200 to 960 Hz.
It is usually transmitted as a digital signal with a communication speed of about 0 bits/second. As a future attempt, some methods have been reported in which audio information is converted into digital signals and the three types of information mentioned above are transmitted and received using a single information communication device, It is necessary to digitize at high speed, and a huge amount of information will be generated from just audio. Therefore, in order to perform instant communication, K requires an expressway (IN line) of about 50 to 60 bits/second, and even in the case of instantaneous memory-to-memory communication, a large storage memory is indispensable. This invention has been made in view of the above points, and is constructed on an inexpensive magnetic storage medium using a sequential access method such as a cassette tape, and transmits composite information of 5 images and sounds of the letter F. This invention relates to a system and a system for receiving the composite information onto the magnetic storage medium, and its purpose is to realize a composite information communication device that is inexpensive and has easy operability.Hereinafter, this invention will be explained with reference to the drawings. Figure 1 shows that a cassette tape (hereinafter referred to as NCMT) is a CM

Note that 50 is a blank space. In this example, N documents are stored on the CMT from the first to the Nth, and the counter value after 6898'' is empty. In this case, the number of documents stored is 30 or less. , count value”

In this example, the audio information is added to the third screen 22-3 and the third screen 22-M, and the tape force position information is written in the screen management table 21.

As shown in the figure, it may be arranged in the tape directory section 10 together with the document directory 11. In Figure 2, 11 and 21 are respectively shown in Figure 1 (A).
Document directory inside! J11. It has the same structure as the screen management table 21 in FIG. 1(C). Further, the tape position force wanta value 40 shown in FIG. 1(A) is as follows:
It is possible to use a method of counting unique identification frequencies superimposed on the CMT at fixed length intervals, or a method of counting identification signals written at fixed length intervals on an auxiliary track separate from the information writing trunk. FIGS. 3(A) and 3(B) show one embodiment of this invention.
This figure shows the procedure for transmitting the composite information document on the CMT explained in Figures 2 and 2, and the procedure for configuring the received composite information on the CMT. In FIGS. 3(A) and (B), (1) is the procedure on the sending side, (It
) is the procedure on the receiving side. The method for transmitting/receiving composite information using this procedure is as follows. (a) First, call control is performed using a telephone or the like, and in step (2) and step [1], communication links are established on the sending side and the receiving side, respectively. (p) Next, in the process of step (2), the document left 11 shown in FIG. 1(A) and the screen management table 21 shown in FIG. 1(C)K are read from the CMT 60 and sent to the receiving side. . On the receiving side, the processing IC in step [2] receives the composite information and stores it in a storage area such as an IC memory. (c) The receiving side calculates the document length in step [3] based on the received document briefing information. The document length is the tape length determined from the difference between the document start position 14 and the document end position 15 shown in FIG. 1(B). ) Next, in the process of step [4], the own CMT70
Checks the free area of the document and replies to the sending side whether or not the document can be received. (E) In response to the response to (C) above, the transmitter performs step ■
(Step (2) is not used in relation to the procedure (If) on the receiving side) to determine whether to start or correct document transmission, and if transmission is possible, the process moves to screen information transmission, and if transmission is not possible, to line disconnection. Also, if the receiving side responds that the information can be received, the process proceeds to receiving the screen information, and if not, the process proceeds to disconnecting the line. (f) When transmitting and receiving screen information, the screen type is first determined in steps (2) and (5) for both transmission and reception. The screen type is identified by the screen type 21b (FIG. 1(D)) in the screen management table 21 sent and received in the step ←). (g) In the case of a character screen, the information is read and transmitted from the transmitting side CMT 60 in the processing of step
Store in . The amount of information is fixed at 2 bytes on both the transmitting and receiving sides. ←→ For the image screen, step ■ and step [7]
], fixed length (96 bytes) image information is sent and received. (S) After sending and receiving the screen information, in the process of step ) process is repeated. Check the number of document screens as described above (
-) The number of screens in the document directory 11 sent and received is 16 (Fig. 1(B)) K. ■) After completing sending/receiving the entire screen, proceed to step ■.

In the process [9], the communication mode is switched from the modem to the telephone, that is, from digital information transfer to analog information transfer. Ql, 1 Thereafter, in step [phase], [scream], audio information is transferred from the transmitting side CMT 60 to the receiving side CMT 70. In this case, the transfer length is determined by (q) each screen + J additional audio determined from the additional audio start/end position information 21d and 21s in the screen management table 21 (Fig. 1 (D)) that has been sent and received by K. It is determined by the length of the needles. (4) After transmitting and receiving all voice information, the communication mode is switched from the telephone to the modem in step Q for both transmission and reception, in the process of (11). (W) Next, for both sending and receiving, step @ , 1)
In step 2), perform line disconnection processing. Yu) Finally, the Ukei 6 side snaps (1: (In I,
The tape counter position information of the document directory 11 and screen management table 21 that have already been received in step (p) is corrected to match the own CMT 70, and is written to a predetermined position VC of this CMT 70. By following the steps described above, it is possible to transmit composite information on the CMT 60 and to configure exactly the same composite information on the receiving side on its own CMT 7G. As explained above, the present invention (11 characters and 1 image information is sent and received as digital information for each screen, and audio information is sent and received as analogue information added to each screen) This method has the advantage that complex information documents can be easily transferred using existing communication lines such as networks. (2) Also, prior to transmitting the document, the document size can be transmitted using a tape length on the CMT. This has the advantage that the receiving side can check the free space in its own CMT and reply with a judgment of whether it can receive the document or not. By transmitting the size in advance and observing the procedure for transmitting screen information and audio information together, there is an advantage that the transmission/reception mode between digital screen information and analog audio information can be easily switched.
