Latest Patents
Fredreck H Auld holds a patent for a data encryption technique specifically designed for subscription television systems. This patent involves a head-end that transmits selected fields of a television signal in a scrambled form. The scrambled fields are identified by an encrypted mode control code, which is inserted in a selected horizontal line of the preceding vertical interval. The mode control code is structured to realize a predetermined non-transmitted control code when processed with vertical interval system control data. A decoder is employed to process the received mode control code and system control data, enabling the unscrambling of the following field. Notably, the decoder may utilize majority voting techniques, allowing for the recovery of the control code even if not all bits are properly recovered.
