Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of transmitting and reproducing image information in an image information service system such as a videotex system.

[0002]

2. Description of the Related Art In recent years, images such as videotex systems that provide familiar information such as news and weather information and business information as image information consisting of character information and graphic information that are easy for users to understand Information service systems are becoming popular.

An example of the configuration of the image information service system will be described below with reference to FIG. An image information service center 1 in FIG. 2 is an auxiliary storage device 1a such as a magnetic disk device or a magnetic tape device that stores a plurality of the image information as a database, and an image information editing device that creates and edits the image information. 1b, a communication processing device 1c for transmitting and receiving the image information and a screen number for searching the image information to and from a data transmission network such as a telephone line network, and managing the image information database to manage the screen number. The main frame computer 1d performs processing such as transmitting the image information retrieved and read based on the above to the data transmission network via the communication processing device 1c.

Reference numeral 2 in FIG. 2 is an image information terminal device, and the screen number and the image are connected between the key input device 2a for the user to input a control command and the screen number and the data transmission network. A modem device 2b for transmitting and receiving information,

Alternatively, the control unit 2e receives the image information transmitted from the image information service center 1 via the modem unit 2b, stores it in the storage unit 2d, decodes it, and displays it on the display unit 2c.

Reference numeral 3 in FIG. 2 is a data transmission network such as a telephone line network for transmitting various data such as image information and screen numbers transmitted and received between the image information service center 1 and the image information terminal device 2.

An operation example of the image information service of the image information service system including the above components will be described. FIG. 3 is a flowchart showing an operation example of the image information service of the conventional image information service system, which will be described below with reference to FIG.

First, the control device 2e of the image information terminal device 2
Is input by the user using the key input device 2a,
The screen number set in the storage device 2d is read and transmitted from the modem device 2b to the image information service center 1 via the data transmission network 3. This process is shown as (A1) in the flow diagram of FIG. Hereinafter, each process will be indicated by an A number at the end of each flowchart and the flowchart of FIG.

The mainframe computer 1d of the image information service center 1 receives the screen number from the communication processing device 1c, and uses the screen number as a target from the image information database stored in the auxiliary storage device 1a. The image information to be processed and its attribute information are searched and read (A2).

The searched image information is composed of a plurality of screens,
It is judged from the retrieved attribute information whether the screen display interval is designated (A3).

If the image information is composed of a plurality of screens, the mainframe computer 1d transmits each screen information from the communication processing device 1c to the image information terminal device 2 via the data transmission network 3, and the screen information is transmitted. After each transmission, the interval until the next screen information is transmitted is set based on the display interval information included in the attribute information (A4).

The control device 2e of the image information terminal device 2 receives the image information composed of a plurality of screens transmitted from the image information service center 1 from the modem device 2b and measures the reception interval between the screen information to obtain the information. The time data is added to the screen information as display interval information and stored in a pre-allocated storage area of the storage device 2d (A5).

If the image information is not composed of a plurality of screens in step A3, the image information service center 1
The mainframe computer 1d transmits image information from the communication processing device 1c to the image information terminal device 2 via the data transmission network 3 (A6).

The control device 2e of the image terminal device 2 receives the image information transmitted from the image information service center 1 from the modem device 2b and stores it in a pre-allocated storage area of the storage device 2d (A7).

After step A5 or step A7, the control device 2e of the image information terminal device 2 reads and decodes the image information stored in the storage device 2d, and the display device 2
One screen of information is displayed on c (A8).

Next, the control device 2e of the image information terminal device 2
Determines whether display interval information is added to the screen information, and if not added, ends the processing (A9).

If added, a plurality of pieces of screen information are sequentially displayed while the interval until the next screen information is read and displayed is set according to the display interval information (A10).

The above is an explanation of one example of the operation of the image information service of the conventional image information service system based on FIG.

[0018]

However, in the above-described image information transmission / reproduction method, when transmitting image information having a plurality of screens and the display interval between the screens is designated, one screen information is transmitted. After that, the data transmission interval has to be increased according to the specified display interval until the next screen information is transmitted, and the transmission efficiency decreases (for example, if the display interval is specified as 20 seconds and the image information of 10 screens is transmitted). If so, 20 × (10-1) = 180 seconds, that is, it takes 3 minutes extra time. Further, since the display interval timing is controlled by the image information center side, the timing deviation of data transmission in the data transmission network and the image information There is a problem that the display interval timing on the image information terminal may not be accurately reproduced as specified due to the data reception timing deviation on the terminal side. Which was.

In view of the above problems, the present invention does not require a transmission interval according to the display interval even when transmitting image information having a plurality of screens and the display interval between the screens is designated, and the image It is an object of the present invention to provide an image information transmission / reproduction method capable of accurately reproducing a display interval timing on an information terminal as specified.
