Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a videotex terminal device for storing and displaying image information transmitted in a videotex network in a memory.

Conventional technology Information that can be selected and transmitted according to a request from the terminal among various information stored in the information center file, processed by the terminal, displayed on the display unit, and stored and searched for necessary image information in the memory. A search system has been proposed.

For example, as shown in FIG. 3, a request is transmitted from the keypad 3 of the terminal 1 to the captain information center 6 via the interface 15, the modem 12, the line connection unit 11, and the videotex network 5, and the information center 6 is transmitted. Then, according to this request, the image information is retrieved from the image information file 7 and transmitted to the terminal 1.

In the terminal 1, a microprocessor circuit 19 using a microcomputer (CPU) for image information via a modem 15
Then, the display control unit 16 reads it into the video RAM 17 for processing, converts it into an analog signal through the D / A converter 18, and displays it on the display unit 2. Then, the image information received at the same time is stored in the memory 21 in image information units. The image information stored in the memory 21 is
By operating the keypad 3 of the terminal 1, it is possible to display on the display unit 2 in screen units.

Here, 4 is a telephone, 13 is a microprocessor circuit 19
RAM, which is used as a work area required to be controlled by
Is a program ROM.

Problems to be Solved by the Invention As described above, in the conventional image information storing / reproducing system,
When the terminal device stores and reproduces and displays a plurality of pieces of image information (hereinafter, referred to as continuous transmission screen) continuously transmitted at a time interval designated by the information center 6 in units of image information, the received image information is the image information. Since each unit is stored in the memory 21, the user operates the keypad 3 for each screen to display the next screen. The display interval of each image information is displayed while receiving from the information center 6. When,
There is a problem that the state in which the image information stored in the memory 21 is displayed is different.

In view of the above problems, it is an object of the present invention to provide a videotex terminal device capable of reproducing image information stored in a memory of a terminal in the same state as when it is displayed while being received from an information center. It is what

Means for Solving the Problems The videotex terminal device of the present invention comprises a first memory for storing image information, a measuring means for measuring a reception interval of each screen of continuous transmission screens, and the above-mentioned measuring means. It comprises a second memory for storing the measured time intervals and a control means for reproducing and displaying the image information stored in the first memory at the time intervals stored in the second memory. There is.

According to the videotex terminal device of the present invention, not only the image information but also the time interval of each image information is stored in the second memory by the measuring means. When performing playback display, the user does not operate the keypad on a screen-by-screen basis to display the next screen but uses the continuous sending screen by the control means for playing back and displaying at the time interval stored in the second memory. The next screen can be displayed without any human operation, and can be reproduced and displayed in the same state as when received and displayed from the information center.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a block diagram of an embodiment of the present invention.

In FIG. 1, 22 is a second memory for storing the reception interval of each image information of the continuous transmission screen received from the information center 6, and 19 is a measurement for measuring the reception interval of each image information of the continuous transmission screen. The microprocessor circuit comprises means 23 and control means 24 for reproducing and displaying the image information stored in the first memory 21 at the time intervals stored in the second memory 22. Other configurations are the same as those in FIG.

This terminal device 1 can basically perform the same operation as that shown in FIG. 3, and transmits a request from the keypad 3 to the information center 6 via the videotex circuit network 5, and the captain information center 6 Then, according to this request, the image information is retrieved from the image information file 7 and transmitted to the terminal device 1.

FIG. 2 shows an example of the structure of the continuous transmission screen. When storing the continuous transmission screen, the received image information A is stored in the first memory 21. After the reception of the image information A, the time interval A seconds until the reception of the next image information B is measured by the measuring means 23 and stored in the second memory 22. Hereinafter, the same processing is repeated to store the image information A, B, and C in the first memory 21,
The time intervals A and B are stored in the second memory 22.

When the continuous transmission screen stored in the first memory 21 is to be reproduced and displayed, the control means 24 first displays the image information A, and after the display is completed, the time interval A seconds is read from the second memory 22, and A The display process is interrupted for a second, and the image information B is displayed after A seconds. The same process is repeated thereafter.

With such a configuration, the continuous transmission screen stored in the first memory 21 of the terminal can be reproduced and displayed in the same state as when it is displayed while being received from the information center 6.

EFFECTS OF THE INVENTION As described above, according to the present invention, there is an advantage that the continuous transmission screen stored in the memory of the terminal can be reproduced and displayed in the same state as when it is displayed while being received from the information center.
