Abstract

PURPOSE:To allow the user to display optional image information through selection by storing received image information in a memory for image information storage, reading only header information of a stored image information group after line connection/disconnection and displaying it as a list. CONSTITUTION:A request (index number) is sent from a key pad 3 via a videotex circuit network 5, a CAPTAIN information center 6 retrieves image information from an image information file to send it to a terminal equipment 1. Then the much received image information is written sequentially in an image memory 21 and stored therein. Then a line connection section 11 connects the terminal equipment 1 to a telephone set 4. Then only the header information is read from each image information stored in the image memory 21 by a 1st control means of a microprocessor circuit 19 by an instruction from the key pad 3, processed by a display control section 16 and a video RAM 17, converted into an analog signal by a D/A converter 18 and displayed as a list on a display section 2 of a cathode-ray tube or the like.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a Videotex terminal device that stores and displays image information transmitted over a Videotex network in a memory.

The various information accumulated in the files of the conventional technical information center is selected and transmitted according to the request from the terminal, processed by the terminal,
An information retrieval system that displays information on a display unit has been proposed.

For example, as shown in FIG. 4, from the key site 3 of the terminal 1 to the captain information center 6, the refresher interface 15. Modem 12° line connection section 11.
The information is transmitted via the videotex circuit 5, and the information center 6 searches for images from the image information file to the search 3 and sends them to the terminal 1 in accordance with this request. .

In the terminal 1, image information is demodulated and received by a modem 12, read into a video RAM 17 via an interface 15 by a microprocessor circuit 19 using a microcomputer (CPU) and a display control unit 16, and processed. The signal is converted into an analog signal through an A converter 18 and displayed on a display unit 2 made up of a cathode ray tube or the like. Here, 4 is a telephone, 13 is a RAM used as a work area necessary for control by the microprocessor circuit 19, and 14 is a program ROM.

Problems to be Solved by the Invention In the conventional search method described above, each time there is image information to be searched, the keypad 3 is operated to obtain the desired image information. If you wish to receive the information again, you will need to receive it from the information center 6 via the telephone line again, which is a time-consuming operation and requires additional line usage fees. was there.

In view of the conventional problems as described above, the present invention eliminates the need to receive image information once received from an information center via a telephone line, and therefore provides a videotex terminal device that is economically less burdensome. The purpose is to provide the following.

Means for Solving the Problems The videotex terminal device of the present invention includes a memory for storing image information of received videotex information, and selects only header information from the image information stored in this memory. a microprocessor circuit having a first control means for displaying screen information and a second control means for displaying only selected screen information from the image information stored in the memory; After storing the image information, the communication line is disconnected, the first control means selects and displays a list of only the header information of the stored image information, and upon receiving instructions from the user using the display screen,
This is a 5-7 type device configured to display only the image information instructed by the second control means.

According to the Videotex terminal device of the present invention, the received image information is stored in the memory, and after the communication line is disconnected, the first and second image information is selected from among the image information stored in the memory.
With the control means, it is possible to selectively display the screen information of any image from the memory, and once received, a large amount of image information can be easily operated and at low cost without requiring line usage fees. can be displayed.

EXAMPLE Hereinafter, one example of the present invention will be explained using FIGS. 1 to 3. FIG. 1 shows a block diagram of an embodiment of the present invention, and FIGS. 2 and 3 show examples of displaying image information.

In FIG. 1, 21 is an image memory that stores image information received from the information center 6. The other configurations are the same as in FIG. 4.

This terminal device 1 can basically perform the same operation as the one in FIG. The captain information center 6 transmits the image information file 7 according to this request.
Image information is searched for and transmitted to the terminal device 1.

Then, a large amount of received image information is sequentially written into the image memory 21 and stored. After this, the line connection section 11
The terminal device 1 is disconnected from the Videotex circuit network 6, and the terminal device 1 is connected to the telephone set 4.

Then, in response to an instruction from the keypad 3, the first control means of the microprocessor circuit 19 controls the image memory 2.
Only the header information of each image information stored in 1 is read out, processed by the display control unit 16 and video RAM 17, and converted into an analog signal by the D/A converter 18.
A list is displayed on a display section 2 such as a cathode ray tube. FIG. 2 shows an example of a list display state of only the header information of this image information.

Here, an example is shown in which only the information provider name, unit price, and screen number are selected and displayed. By showing both sides in Table 7, the user can clearly see what kind of image information is currently stored in the image memory 21.

Furthermore, the user sees this list of header information,
The user selects the image information desired to display from among them and instructs it using the keypad 3. In response to this instruction from the keypad 3, the second control means of the microprocessor circuit 19 selects and reads out only the screen information of an arbitrary image from among the image information stored in the image memory 21, and the display control section 16 and video RAM 17 , and converted into an analog signal by a D/A converter 18 , the signal is displayed on the display section 2 .

According to this configuration, image information once received can be viewed any number of times with a simple operation after the line is disconnected.

Furthermore, as a second embodiment, in the display state of only the header information of the image information shown in FIG. 2, the third control means of the microprocessor circuit 19 assigns a relative number A and displays You may also do so. FIG. 3 shows the display state.

Then, by inputting an instruction corresponding to the assigned relative number A from the keypad 3, the image information corresponding to the header part information of the image information assigned the relative number A is transferred to the microprocessor circuit 19. The screen information selected by the control means 4 is displayed on the display section 2 in the same manner as described above.

By adopting the configuration of the second embodiment, the original purpose can be achieved with a simpler operation.

Furthermore, as a third embodiment, when only the header information of the image information is displayed as shown in FIG. By displaying only the screen number (screen number, etc.), the display can be made simpler and more convenient for operation.

Effects of the Invention As described above, according to the present invention, received image 9 vane information is stored in a memory for storing image information, and after the line is disconnected,
By reading only the header information of the stored image information group and displaying it as a list, the user can select and display any image information using the list display, making it easier to operate. It also has the advantage of being extremely economical in terms of line usage charges.
