Cryptography > Video Cryptography > Video Electric Signal Modification (e.g., Scrambling) > Modifying Accompanying Audio Signal Modifying Accompanying Audio SignalModifying Accompanying Audio 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.06/22/06 - 20060133611 - Method of use data compression technology A new method of use for compressing technology which allows for a continuous stream of data to be transmitted over pre-existing transmittal lines is described. The highly advanced data compression technology (1) allows large amounts of data, such as video data, to be compressed into small sizes. The compressed data ... 03/23/06 - 20060062386 - Steganographic encoding and decoding of auxiliary codes in media signals One aspect of the invention is a method of decoding an auxiliary code embedded in an audio signal. The method performs a statistical decoding of a multibit auxiliary code embedded in an audio signal. The auxiliary code has been repetitively embedded in the audio signal. The method decodes code values ... 11/24/05 - 20050259822 - Sinusoidal audio coding Coding (1) an audio signal (x) comprises providing a respective set of sampled signal values for each of a plurality of sequential segments. The sampled signal values are analysed (130) to generate one or more sinusoidal components for each of the plurality of sequential segments. The sinusoidal components are linked ... ### FreshPatents.com Support |
