Abstract: Apparatus and methods for embedding and associating triggers within a promotion or other similar content element with the event being promoted are disclosed. In one exemplary embodiment, consumer premises equipment (CPE) such as a digital set-top box is used to interface between the user and an external network (such as an HFC cable network) and facilitate the user selecting and scheduling viewing or recording of a subsequent event (e.g., broadcast movie) via the promotion itself. The trigger(s) within the promotion allow the user to contemporaneously select the promoted event for viewing, recording, etc. without any further action. The trigger(s) then initiates tuning of the user's receiver to the scheduled event at the appropriate date and time. This approach obviates additional actions by the user (such as programming their DVR), and also permits the user to commit to viewing the event when their interest level is highest; i.e., contemporaneous with the promotion.

Abstract: The invention relates to a method and system which are used for the visual scrambling of a video sequence and for the reconstruction (descrambling) of the original content thereof from a digital video stream obtained from encoding based on a wavelet transform. The method for the secure distribution of video sequences according to a digital stream format stems from wavelet-based coding, said format consisting of frames comprising blocks containing wavelet coefficients which describe visual elements. According to the invention, before transmission to the client equipment, the stream is analysed in order to generate (i) a modified main stream through the removal and replacement of certain pieces of information encoding the original stream and having the same format as said original stream, and (ii) a complementary piece of information with any format, comprising digital information which encode the original stream and which can be used to reconstruct the aforementioned modified frames. The modified main stream and the complementary information thus generated are then transmitted separately from the server to the destination equipment and, subsequently, a synthesis of a stream with the nominal format is calculated on the destination equipment as a function of the modified main stream and the complementary information. The invention also relates to a system comprising at least one multimedia server containing the original video sequences, a video stream analysis device, a device for separating the original video stream into a modified main stream and a complementary piece of information according to the aforementioned analysis and at least one device on the destination equipment for the reconstruction of the video stream as a function of the modified main stream and the complementary information.

Abstract: An encryption technology uses an encryption map and video graphics processing technology to combine an encryption map with the image data. Video image processing using maps, such as texture maps, bump maps and the like are combined with an encryption map to generate and encrypted image data. The image is subsequently decrypted using encryption keys that are combined with the encrypted image data using video graphics processing technologies. The decryption map is combined with the encrypted signal to generate a viewable image. The encryption keys may be on a per pixel basis with a separate encryption key for each pixel. Alternatively, an encryption key may contain active keys that may be used to decrypt more than one pixel as well as decoy keys that do not decrypt the signal and thus confound unauthorized decryption attempts. Using encryption maps, single video frames or portions of video frames may be encrypted. The encryption maps may be used with scaled image data and with two dimensional or three dimensional graphics processors.
