Cryptography > Video Cryptography > Video Electric Signal Modification (e.g., Scrambling) > By Modifying Synchronizing Signal By Modifying Synchronizing SignalBy Modifying Synchronizing Signal patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.05/10/07 - 20070104328 - Image signal processing device An image signal processing device, which uses a horizontal synchronizing signal detector to find a frequency (period) of an original horizontal synchronizing signal from an external input horizontal synchronizing signal and provide an internal reference horizontal synchronizing signal with the same frequency same as the original horizontal synchronizing signal to ... 02/08/07 - 20070030968 - Digital processing disruption stems A method and apparatus are described for modifying an analogue video signal to impair its conversion to a digital signal by an analogue to digital converter. The resulting modified signal may prevent the operation of the analogue to digital converter altogether, or even if a digital signal can be output ... 10/26/06 - 20060239458 - Communications system with minimum error cryptographic resynchronization A synchronized communications system permits resynchronization in late-entry or fade-recovery conditions. A plurality of communications devices are operative for communicating in a synchronized, encrypted communications channel between each other. At least one of the communications devices is operative for continuously transmitting a resynchronization header that includes a start-of-message field that ... 09/14/06 - 20060204007 - System and method for detecting aes random number generator synchronization errors In accordance with the teachings of the present invention, a system and method for detecting AES random number generator synchronization errors are provided. In particular embodiments of the present invention, the method includes generating a first synchronization word at a playback server, the first synchronization word comprising a 10-bit advanced ... 07/13/06 - 20060153380 - Personal cryptoprotective complex The invention relates to information protection and user identification. The technical result consists in functionality enhancement including: information encryption and decryption; electronic document authentication using an electronic digital signature; protection of electronic documents against copying, exchange of copy-protected electronic documents; settlements by means of electronic payment facilities; protection of software ... ### FreshPatents.com Support |
