CA 1236885

ABSTRACT A multi-channel broadcasting system in which encrypted data signals are transmitted in either or both directions between a central terminal and any one of a number of subscriber terminals. When a subscriber selects a secure channel dedicated to the transmission of encrypted data, the terminal is temporarily connected to a further channel dedicated to the transmission of encryption and/or decryption information signals. The transmitted encryption and decryption information signals are stored and used to encrypt and decrypt the data signal to be transmitted after the terminal is switched back to the selected secure channel. The stored encryption and decryption information signals are subsequently canceled.
