Title:
SIGNAL TRANSMITTING METHOD BETWEEN COMMUNICATION STATIONS
Document Type and Number:
Japanese Patent JP3688328
Kind Code:
B2
Abstract:
PURPOSE: To transmit a signal between communication stations depending on an area corresponding to the image position of a mark by permitting the communication stations connected to a network to generate the pictures where the marks are given to the individual image positions and to transmit them to the plural communication stations.
CONSTITUTION: Terminals 3a-3c are provided with telephone sets 31 and TV receivers 33 having teletext decoders. A control station 2 is connected to the information sources of a data bank 4a, a teleshopping system 4b, a video on demand device 4c. When the key of the keyboard of the telephone set 31 in the terminal is depressed, a central station 2 refers to a corresponding teletext page and shows a virtual reality environment having a road 301 along the marks arranged as a department store 302, a station 301, a video shop 304, a bar 305. When a user 310 is moved to positions 310a-310d by a positioned key, and it is brought into contact with the desired mark, communication between the terminals is connected, and data can be transmitted between the terminals.
