摘要： An encryption device can be used to encrypt information units conveyed by cells that are broadcast from an optical broadcast node to network units by a passive optical network. Each cell conveys at least one information unit and each information unit is addressed to a respective subscriber terminal. The device includes an encryption system that receives in clear at least one key from at least one decryption device located in a network unit. Applications include ATM telecommunication networks.

摘要： The invention relates to a method of regenerating the modulation carrier wave of an original modulated signal (SL) which has symmetrical frequency components about the carrier. A phase discriminator (D1) which receives two image signals (SL, S11) of the original signal controls the frequency of a local oscillator (OL), the frequency spectrum of one of the image signals being inverted with respect to that of the original signal and the difference in frequencies between these two image signals being twice that between the local carrier and the carrier of the original signal. Application to the synchronous demodulation of a television signal.
