Abstract (en)
On connection (6), a redaction computer (5) puts the signals into a modulator-adapter (7) suitable for the input into a transmission modulator (8). The signal amplified by an amplifier (9) is transmitted into the ether and captured by antennae (11) of users. From these antennae (11), a receiver (12) picks and gives it up to a modulator-adaptor (13) which makes it compatible with a micro-processor (14) acting as as data access-key in order to allow the signal differentiation in only one emission. If the decodified message arrived form the modulator-adapter (13) has correspondence of codification with the micro-processor (14), a device (15) is activated which consists of a printing device or of a magnetic memorizer for computers, if it is about either a text to transmit or a transducer for the control of electrical machinery. Furthermore, to accede to the radaction computer, the user will digitate the reference codes for services and news which can be deduced from tabulates transmitted by the editor. By means of orders, the programme of each peripheral computer will automatically send the necessary data on a line which allows the system to turn out interactive.
