Cryptography > Video Cryptography > Video Electric Signal Modification (e.g., Scrambling) > Image Data Converted To Digital Before Modification > Having Compression (e.g., Mpeg) Having Compression (e.g., Mpeg)Having Compression (e.g., Mpeg) 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.09/20/07 - 20070217607 - Repetition coded compression for encrypting highly correlated data A method for an encryption of highly correlated data using a repetition coded compression is disclosed. The method includes the steps of receiving digital data, reshaping the digital data into a digital data matrix, encoding the repetitions of elements in the digital data matrix into a bit-plane index to form ... 07/12/07 - 20070160209 - Content management method, content management program, and electronic device Data in a storage medium not using an encryption double key scheme is transferred to a storage medium using an encryption double key scheme. A title key Kt encrypting content data C in an SD audio card SDa is further encrypted by a user key Kua generated in a key ... 05/03/07 - 20070098167 - Information processing device, information recording medium and information processing method, and computer program A configuration is provided which improves scrambling processing of content and eliminates unauthorized use of content. Scramble rules which differ for each content are used for content scrambling processing. For example, in the event of using shuffling processing, various shuffle states are specified as scramble rules. In the event of ... 12/07/06 - 20060274895 - Transmitter apparatus for mpeg-4 ipmp extended isma media stream A device which transmits an ISMA media stream subjected to MPEG-4 IPMP extension. An ISMA media stream having an ISMA header and including contents as a payload is constituted, an IPMP tool list descriptor representing, as a tool required for processing of the contents, at least one tool selected from ... 10/12/06 - 20060227970 - Image display system An image control apparatus in an image display system applies scrambling only to image data which requires content protection and notifies to a display apparatus which pixel or pixels are scrambled. Alternatively, when a plurality of windows are displayed at the same time, the image control apparatus scrambles each window ... 03/16/06 - 20060056627 - Tunneling information in compressed audio and/or video bit streams A method for conveying private or enhancement information in a compressed bit stream comprising the steps of (A) generating a compressed bit stream in response to a first data stream and a plurality of encoding choices and (B) controlling the encoding choices in response to a second data stream comprising ... 03/09/06 - 20060050881 - Encoding documents using pixel classification-based preprocessing and jpeg encoding A method for JPEG encoding an image that includes preprocessing steps performed prior to a JPEG compression step. The preprocessing steps include transforming block image data, using a variable quantization table selected for each block according to the classification of pixels in that block to produce quantized image data, and ... 01/05/06 - 20060002552 - Automatic and adaptive process and system for analyzing and scrambling digital video streams A process for automatically and adaptively scrambling digital video streams including analyzing structure and visual content of the digital video stream, and scrambling the digital video stream under regulation of an inference or decisional engine that selects a scrambling tool or tools to be applied to the digital video stream ... 01/05/06 - 20060002551 - In-band signaling to control encryption and transcoding resources in vod/on-demand system A method for controlling flow of a video content signal through a communications system, such as a video on-demand system creates a unique message for each individual video content signal and attaches the unique message to each individual video content signal prior to transmitting the video content signal through the ... 09/29/05 - 20050213760 - Device for the transformation of mpeg 2-type multimedia and audiovisual contents into secured contents of the same type A process for distributing video sequences according to a nominal flux format including a succession of images, where each image includes a succession of blocks, and in which at least one of blocks in one of the images is calculated by motion prediction relative to at least one reference image, ... 06/23/05 - 20050135619 - Apparatus and method for encoding and storage of digital image and audio signals An apparatus and method for the encoding and storage of signals representing at least image information onto a storage medium is claimed. A source generator is configured to convert the signals into digitized image information. A compressor is configured to receive the digitized image information from the source generator and ... 06/09/05 - 20050123136 - Motion picture file encryption method and digital rights management method using the same A method of encrypting a motion picture file and a method of digital rights management using the same, wherein encryption method includes: extracting information on the location of at least one video sample, which is a real-time streaming unit, from meta-data of the motion picture file; extracting the video samples ... ### FreshPatents.com Support |
