摘要:
In one embodiment the present invention includes a system for identifying an unauthorized display of content. The system includes a preprocessor, an inserter, an observation device, and a subscriber information device. The preprocessor device preprocesses the content for subsequent insertion of semi-visible information. The inserter device inserts a semi-visible watermark into the content as having been preprocessed by the preprocessor device. The semi-visible watermark corresponds to a subscriber identifier. The observation device executes processing, including receiving an input from an observer that observes a display of the content that includes the semi-visible watermark. The input corresponds to the semi visible watermark. The processing further includes processing the input to generate an input result. The subscriber information device stores subscriber identifiers and identifies a particular subscriber by comparing the input result and the subscriber identifiers.

A content distribution system and method which prevents unauthorized access to secured content such as movies and music. The system includes a source, a receiver, an authorized security device such as a conditional access module (CAM) for decrypting authorized content and an output device for outputting content. The system can also include a backend for managing accounts and system operations. One aspect of this invention is that the content data is derived from the Internet. The system allows for the verification of authorization to play secured content, the addition of watermarks to the secured content, the conversion of the secured content to a displayable form and the means for preventing output of the secured content.
摘要:
To enable the source of an unauthorized copy of an information-bearing medium, such as a video DVD, to be traced, a compressed digital signal stream to be stored on the medium is altered to include “running marks,” that comprise pixel blocks changing in position frame by frame and encoded with information designating where and when the copy was made. The medium under test is played back synchronously with a reference medium containing the locations of the running marks together with original video. The source of copying message is advantageously encrypted and scrambled to avoid detection or alteration by a copyist. The message preferably is spread, for example into a spread spectrum carrier, to enhance discrimination among a large number of sources and enable demodulation in the presence of noise.

A content distribution system and method which prevents unauthorized access to secured content such as movies and music. The apparatus includes a source, a receiver, an authorized security device such as a conditional access module (CAM) for decrypting authorized content, an output device for outputting content and a backend for managing accounts and system operations. One aspect of this invention provides a mechanism for providing secured content on a medium such as a DVD optical disc. These devices may verify that there is authorization to play the secured content, add watermarks to the secured content, convert the secured content to a displayable form and provide a means for preventing output of the secured content.

One embodiment of the present invention includes a system comprising a housing having an upper end and a lower end. The housing carries a plurality of movable blades defining an entry aperture proximate to the upper end, an exit aperture proximate to the lower end, and a chamber there between. An adapter may be provided for connection to the housing and for receiving an article storage container. The upper end of the housing carries a sensor responsive to the presence and absence of the article storage container. A memory device carries information about the presence and absence of the article storage container. An article determining and actuating station has electronics for interrogating the memory device, for controlling the plurality of blades and for determining the number of items dispensed. A receptacle collects articles that have been dispensed. Methods of associating a flow control device with an article storage container and of dispensing items are also disclosed.

Methods and apparatus for navigating video content. Digital markers may be placed at desired locations within recorded or cached video content. In one embodiment, these markers (or bookmarks) may be used to instantly jump to a particular scene or location within a video presentation. Such markers may be manually or automatically placed during live caching of video content or playback of previously recorded content. In another embodiment, selectable thumbnailed images that are representative of the video content at previously bookmarked locations may be presented to a user. Such selectable thumbnailed images may be integrated with a DVR status bar and, when selected, may be used to begin viewing stored video content from the bookmark corresponding to which ever thumbnail is chosen.

Characterizing descriptor information for a presently viewed program is used to develop selection criteria by which to identify other program choices of potential interest to the viewer. Such options are then displayed to the viewer, either upon command or automatically at a time that is temporally proximal to a conclusion of the presently viewed program.
