Latest Patents

Zacharski's latest patents include a method and apparatus for scrambling and unscrambling communication. This invention focuses on television video and audio signals in a subscription television system. The system allows for program selections of subscribers to be known at a central transmitting site. Control signals are encoded into vertical blanking intervals of the video signals, which are addressed to receivers authorized to receive unscrambled transmissions. This selective control enables unscrambling at those receivers. The unscrambler at each subscriber's receiver decodes the control signals. If the signals are addressed to a particular subscriber's receiver, they operate to enable or disable the unscrambler. This method frequently varies its mode of operation, greatly increasing the security of the system and deterring unauthorized viewing of scrambled transmissions. Video scrambling and unscrambling are achieved by inverting selected horizontal lines of a transmitted television picture. A technique is also disclosed for inversion of alternate groups of equal numbers of lines.
