TLDR
In this article, a set-top box (10) is provided to each consumer and contains a copy protection circuit which is adapted to apply selected anticopy waveforms to the video signal corresponding to the program material in response to commands from the service providers (3).Abstract:
A method and system of providing copy protection of video analog and digital signals and the like, wherein the signals are transmitted via a digital delivery network, and may comprise, for example, pay-per-view (PPV) program materials protected by copyrights of respective program rights holders. The right holders authorize video service providers (3) to apply copy protection to the program material. The copy protection process is supplied to the rights holders or the service providers (3) by a copy protection process licensor. The video service providers (3) supply suitable copy protection control software via respective control and billing (tracking) centers to generate commands which activate, control and reconfigure the copy protection process being applied to the programs being transmitted. A set-top box (10) is provided to each consumer and contains a copy protection circuit which is adapted to apply selected anticopy waveforms to the video signal corresponding to the program material in response to the commands from the service providers (3). Usage data pertinent to each consumer is returned by the set-top box (10) to the service providers (3), which then report the copy protection usage to the respective rights holders and process licensor.read more

Patent
Steganographic method and device
TL;DR: In this paper, an apparatus and method for encoding and decoding additional information into a stream of digitized samples in an integral manner is presented. But the method does not cause a significant degradation to the sample stream.
Patent
Optimization methods for the insertion, protection, and detection of digital watermarks in digitized data
TL;DR: In this article, the authors present methods and systems for encoding digital watermarks into content signals, including window identifier for identifying a sample window in the signal; an interval calculator for determining a quantization interval of the sample window; and a sampler for normalizing sample window to provide normalized samples.
Patent
System for controlling the distribution and use of rendered digital works through watermarking
TL;DR: A trusted rendering system as mentioned in this paper facilitates the protection of rendered digital works which have been rendered on a system which controls the distribution and use of digital works through the use of dynamically generated watermark information that is embedded in the rendered output.
Patent
Method and system for digital watermarking
TL;DR: In this article, a method for applying a digital watermark to a content signal is described, and a watermarking key is identified, which includes a binary sequence and information describing application of that binary sequence to the content signal.
Patent
Method of inserting/overlaying markers, data packets and objects relative to viewable content and enabling live social networking, n-dimensional virtual environments and/or other value derivable from the content
TL;DR: In this paper, a method by which a user can associate selectable Markers, Data Packets and/or Objects with Content is presented, where the Content may be distributed electronically, and the Markers allow for insertion and overlay of Objects when the Content is selected for viewing by a Viewer.

Patent
Copy protection for hybrid digital video tape recording and unprotected source material
TL;DR: In this article, a hybrid digital/analog video recorder prevents both analog and digital copying by detecting anti-copy bits present in the input material and in response preventing recording, and then adding an anti copy bit to the input digital stream, preventing later copying of such material.
Patent
Apparatus and method for comprehensive copy protection for video platforms and unprotected source material
TL;DR: In this paper, a video recording platform prevents both analog and digital copying of copy protected material by using a specially adapted video recorder, playback device (10, 100), or set top decoder.
Patent
Apparatus and method for preventing unauthorized copying of video signals
TL;DR: In this article, a copy protect bit in the reproduced digital video signal is detected, and a code is generated and inserted into the vertical blanking interval of the reproduced video signal in a digital video tape recorder.
Patent
Intelligent multimedia set-top control method and apparatus in which billing signals are communicated to an information network upon presentation of downloaded media programs
TL;DR: In this article, a method and apparatus for effectuating the reception and local storage of source information signals representative of a media program transmitted from a source information network over a cable television channel on a pay-per-view basis is disclosed.
Patent
Method and apparatus for processing a video signal so as to prohibit the making of acceptable video tape recordings thereof
TL;DR: In this article, a video signal is modified so that a television receiver will still provide a normal color picture from the modified video signal while a videotape recording of the recorded video signal produces generally unacceptable pictures.
