The system was scrambled analog video OTA, with a decoding signal (and audio) sent to subscribers via phone line. Worked by switching a delay line in and out of the transmitted signal path, producing a "venetian blind" kind of effect unless the delay was compensated for on the receiving end, in step with the decoding signal.
