Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a videotex user terminal device that provides transmission services such as image information.

BACKGROUND ART FIG. 2 is a block diagram showing the configuration of a conventional user terminal device. In FIG. 2, 11 is the Videotex network 7.
A line connection section consisting of a modem, etc. that controls the connection with the
2 is an image information data processing unit that performs decoding processing of image information data received from the Videotex network 7; 13 is a display memory that stores the decoded data; 14;
15 is a display control unit that performs controls such as reading out display data from the display memory and outputting it as a display signal; 15 is a processing unit that inputs a request signal from a keypad and sends it to the Videotex network 7 via a line connection unit; 16 is a keypad for inputting request signals and the like. Further, 7 is a Videotex network, and 18 is a receiver.

The operation of the conventional user terminal device configured as described above will be explained.

When displaying character and graphic information on the receiver 18 using a user terminal device, a request (image information number, etc.) is input using the keypad 16.

The input request is received by the remote control reception processing section 15, and a helical request signal is sent to the Videotex network 7 via the line connection section 11. Image information data corresponding to the request signal is transmitted through the Videotex network. The transmitted image information data is received by the line connection section 11, subjected to decoding processing etc. by the image information data processing section 12, and stored in the display memory 13. The stored data is displayed in the display control unit 1.
4, the signal is read out from the display memory 13, processed, and output as a display signal to the receiver 18 for display.

However, this is the problem that the invention attempts to solve! In such a conventional configuration, when a user uses a user terminal device, one display of image information data corresponding to a request signal input from one key band is performed when the user is connected to the Videotex network. . The user receives the above-mentioned display information service. In other words, while displaying an image, the upstream signal to the Videotex network (
Request signal) and downlink signal (image information data) are not transmitted and received, but are used for the second transmission and reception between them (
The problem was that the second screen display request) could not be performed.

The present invention solves the above-mentioned conventional problems, and aims to provide a user terminal device that allows multiple users to receive image information services at the same time, that is, allows second transmission and reception.

Means for Solving the Problems In order to achieve the above object, the present invention has a nine-line connection section connected to the Videotex network, an image information data processing section that performs decoding processing of image information data, etc. A plurality of at least first... a second display section, a request signal processing section that outputs a destination instruction signal that stores the source of the request signal inputted from the plurality of keypad nodes and indicates the destination of the image information data, and the line connection section. and a data distribution processing circuit that receives a destination instruction signal from a request signal processing section and transmits the image information data received through the display section to the designated display section.

Effects of the present invention When requesting display of image information using request signals from a plurality of display sections using the apparatus having the above-described configuration, the key band Yoshi IJ quest signal of the first display section is input, and the request signal processing is performed. The unit receives it, stores the sending source, and outputs a destination instruction signal to the data distribution processing unit, and sends the request signal to the Videotex network via the line connection unit, where the image information data corresponding to the request signal is sent. It is transmitted through the Videotex network, inputted to the data distribution processing circuit via the line connection section, outputted to the corresponding first display section according to the instruction signal outputted from the request signal processing section, and decoded by the image information data processing section. Performs processing, stores data in display memory,
The data read from the display memory is output as a display signal by the display control unit and displayed on the receiver. It is possible to request and display image information data in the same manner as the request request operation of the display unit.

Embodiment FIG. 1 shows a block diagram of a user terminal device in an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a line connection unit composed of a modem etc. that controls the connection with the Videotex network 7, and 2 a l 2 b denotes an image unit that performs decoding processing of image information data received from the Videotex network 7. An information data processing section, 3a and 3b are display memories that store decoded data, and 4a and 4b are display memories 3a.

A display control unit performs controls such as reading out display data from 3b and outputting it as a display signal, and 9 inputs request signals from a plurality of keypads &, 6b, stores the sender of the request signal, and sends out image information data. a request signal processing unit that performs control such as outputting a destination instruction signal instructing a destination; 1o is a data distribution processing circuit that inputs a destination instruction signal from the request signal processing unit 9 and transmits it to the designated display unit; 6a and eb are keypads for inputting request signals, and A and B are display units each consisting of image information data processing units 2a+2b, display memories 31L and 3b, display control devices 41L and 4b, and keypads sa and sb. be. 7 is Videotex network,
81Ll 8b is a receiver for receiving display signals.

The operation of the user terminal device of this embodiment configured as described above will be explained below. With the above configuration, when requesting display of image information based on request signals from multiple display units, the keypad e of the first display unit
A request signal is inputted from &, received by the request signal processing section 9, stores the sending source, and outputs an instruction signal of the sending destination (request source) to the data distribution processing section 10. The request signal is sent to the Videotex network 7 via the line connection section 1, and the image information data corresponding to the request signal is transmitted via the VideoTex network 7, and input to the data distribution processing circuit 1o via the line connection section 1. be done. The image information data inputted to the data distribution processing circuit 1o is outputted to the first display section A by an instruction signal outputted from the request signal processing section 9, and is outputted to the image information data processing section 2a in the first display section A. The data is stored in the display memo IJ 3a, and the data read from the display memory 31L is sent to the display controller 4a.
The output signal is displayed on the receiver 8a as a display signal. While the first display section B is displaying image information, that is, the transmission and reception of the Videotex network 7 is stopped, the second display section B displays the image information in the same way as the request request operation of the first display section B. Requests for information data and display of image information can be made, and image information services can be provided to multiple users. It goes without saying that two or more display sections may be provided.

Effects of the Invention As described above, according to the present invention, the request signal processing section,
By providing a data distribution processing circuit, etc., it is possible to display image information requested by multiple users.
Search efficiency is improved, and usage fees can be reduced because multiple connections can be made with a single Videotex network connection.
