US Patent:

6381747, Apr 30, 2002

Filed:

Aug 31, 1998

Appl. No.:

09/142039

Inventors:

Peter J. Wonfor - El Granada CA
Derek T. Nelson - Menlo Park CA

Assignee:

Macrovision Corp. - Sunnyvale CA

International Classification:

H04N 7173

US Classification:

725104, 386 94, 380201, 380203

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 ( ) to apply copy protection to the program material. The copy protection process is supplied to the rights holders or the service providers ( ) by a copy protection process licensor. The video service providers ( ) 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 settop box ( ) 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 ( ). Usage data pertinent to each consumer is returned by the settop box ( ) to the service providers ( ), which then report the copy protection usage to the respective rights holders and process licensor.

Assignee:

Applied Digital Access, Inc. - San Diego CA

International Classification:

G06F 1100

US Classification:

714712, 714 43

Abstract:

A protocol analysis access system (âPAASâ) and a restricted access method for remotely monitoring and testing embedded channels in a signal communicated over a telecommunications network. The PAAS system is capable of accessing a signal from a network circuit through digital cross-connect systems (âDCSsâ) or through direct connections. In case of restricted network access, the PAAS performs non-intrusive monitor-only function on the signal without interfering with or interrupting the data flow over the network circuit. In addition, the PAAS system is capable of performing non-intrusive conformance testing on a signal using a protocol analyzer. In case of non-restricted network access, the PAAS system allows full performance testing on a signal. The PAAS system functions are executed by an external command source from a remote network maintenance center via remote control links. The monitor-only and test results are reported back to the remote network maintenance center for further analysis.

International Classification:

H04N 591

US Classification:

386 94, 360 60, 380203

Abstract:

Method and apparatus for providing generational copy control of a video signal. A digital video signal contains content information, first supplemental information and second supplemental information. The first supplemental information is represented by a watermark pattern, the second by a control pattern. Copying of the content information is only permitted if a predetermined combination of the first and second supplemental information is present. Pseudo-sync pulses are added to a blanking interval of an analog video signal converted from a digital video signal, the pulses representing the second supplemental information.
