International direct subscriber dialling television system - allows one way and two way communication between subscribers and all system signal sources

摘要

The system offers to a subscriber as 'receiver' a direct dialling of signal sources as 'transmitter' for images, sound and text in international one-way communications. The transmitting signal sources can be dialled in the system with single and multiple numbers in digit-quantity controlled hierarchies of a wide-band dialling network. In a second phase the subscriber as 'transmitter and receiver' are allowed to directly call another subscriber or several other subscribers as 'transmitters and receivers' for images, sound and text in two-way communications using single dialling numbers. ADVANTAGE - Allows images, sound and text to be transmitted directly to and between all subscribers in system by simple direct dialling.
