After that, when the line interface succeeds in connecting to the center, the input information stored in the storage is read and transmission of the stored input information to the center is started.

Further, according to claim 2, the fact that the connection processing with the center in the line corresponding portion is not successful is displayed on the status display portion, and the information input person is informed of that fact.

[0013]

1 is a block diagram showing an embodiment of an information storage system according to the present invention, and the same components as those in FIG. 2 showing a conventional example are represented by the same reference numerals. That is, 1 is an input device for data information, 2a is a terminal device, 3 is a center, and 4 is an exchange.

The terminal device 2a has an input processing unit 21, a line interface unit 22, a storage control unit 23, a storage unit 24, a timer unit 25, and a status display unit 26. The input processing unit 21 combines a plurality of input information and performs processing such as handling as multimedia information. Line interface 22
Performs protocol processing for transmitting the input information to the center 3. The storage control unit 23 performs first-in / first-out type writing and reading parallel processing of input information, and performs processing for storing data from the input processing unit 21 in the storage unit 24. The storage unit 24 is composed of, for example, a randomly accessible magnetic disk device, optical disk device, RAM, etc., and stores input information when it cannot be transmitted to the center 3. The timer unit 25 is composed of, for example, a countdown timer, and measures the time for accumulating the data from the input processing unit 21 in the accumulating unit 25. The status display unit 26 is composed of, for example, a lamp and a display device, and indicates that the terminal device 2a cannot connect to the center 3 and starts accumulation in the internal accumulation device, or stops accumulation because time has passed, etc. Is displayed.

Next, the operation of the above configuration will be described.

If the line connected to the center 3 has a free space, the line is connected to the terminal device 2a.

Here, if the connection is established, the terminal device 2a requests the center 3 for the input information storage service through the line. When ready for storage, the center 3 transmits a preparation completion signal to the terminal device 2a. In response to this, the terminal device 2a displays "center connection in progress" on the status display unit 26 and starts sending the input information to the line. On the other hand, the center 3 starts to accumulate the information sent from the line.

When the terminal device 2a finishes transmitting the input information, "Disconnect" is displayed on the status display section 26, and information indicating that is sent from the line, and the center 3 receives this information and performs the accumulation operation. finish.

On the other hand, when the terminal device 2a cannot connect to the center for some reason, the line interface 22 informs the input processor 21 to that effect. As a result, the terminal device 2a displays "locally storing" on the status display unit 26, and the input processing unit 21 thereafter stores the input data.

“Local accumulation stop” is displayed on and the input is aborted.

Simultaneously with this local accumulation processing, the line interface 22 periodically requests the exchange 4 to connect to the center 3. At this point, the exchange 4 connects the line connected to the center 3 with the terminal device 2a if there is a free line.

Here, if the center connection is established, the terminal device 2a requests the center 3 for the input information storage service through the line. When ready for storage, the center 3 transmits a preparation completion signal to the terminal device 2a.
When the line interface 22 receives this signal, the storage controller 23 is notified of the fact. As a result, in the terminal device 2a, the accumulation control unit 23 reads out the accumulated data from the accumulation unit 24 from the time when accumulation is started, and starts transmission to the line via the line interface unit 22. On the other hand, the center 3 starts to store the video information sent from the line.

At this time, if the information input from the input device 1 is still continuing, the accumulation control unit 23 writes the data from the input processing unit 21 into the accumulation unit 24 and the data from the accumulation unit 24. Is read out and sent to the line interface 22 at the same time.

In the terminal device 2a, when the data transfer from the input device 1 is completed and there is no data to be read from the storage unit 24, and the information transmission is completed, the line corresponding unit 22 passes through the line to that effect. Send information. The center 3 receives this information and ends the accumulation operation.

As described above, according to this embodiment,
Even when the center 3 is stopped or the line of the center 3 is in use, the terminal device 2a can capture the input information from the input device 1 within a predetermined time. Also,
For a line of the same center with a plurality of terminal devices 2a,
Even when service requests are concentrated, the terminal device 2a can capture the input information, and can collectively transfer and store the captured information when the line of the center 3 is free, so that the use efficiency of the center line is improved. Can be achieved.

[0025]

As described above, according to the first or second aspect of the present invention, even when the center is stopped or the line of the center is in use, the terminal device can be operated from the input device. Input information can be captured. In addition, even if there are multiple terminal devices and service requests concentrate on the line of the same center, the terminal device fetches the input information and transfers the fetched information collectively when the center line is idle and stores it. Therefore, it is possible to improve the use efficiency of the center line. It should be noted that the present apparatus is particularly effective when handling Malmettidia information such as video with audio as input information.
