摘要： A method of providing personalized content to a user is disclosed. In particular, the method relates to receiving incoming content that includes primary content being content originally intended for use in a program and personalized replacement content being content for replacing the primary content in the program. If the personalized replacement content is determined to be more appropriate than the primary content, based upon personalization parameters, then the primary content is substituted with the personalized replacement content.

摘要： Embodiments of the present invention are directed to a method and system for altering a presentation of broadcast content. More specifically, embodiments provide an accurate and efficient mechanism for suppressing advertisements by using downloaded templates to identify advertisements before suppression for a duration indicated by information downloaded about the advertisement, where the suppression is effectuated by controlling a display or set-top box using remote-control functionality. In one embodiment, a digital signal comprising broadcast content is accessed. A plurality of templates are received and stored, wherein each template represents a known portion of the broadcast content. The digital signal is then compared against a portion of the plurality of stored templates. Upon a match, a control signal operable to alter a component of a presentation of the known portion of the broadcast content is generated.

摘要： A method of managing revocation when an alternate transmission method, using an alternate transmitter identity and an alternate receiver identity, is juxtaposed into an original transmission system, the original transmission system having its own original transmitter and receiver identities that communicate via an original transmission method involves at an alternate transmission receiver (ATR), providing a digital certificate, the digital certificate cryptographically binding the ATR identity to an original transmission (OT) re-transmitter identity; at the ATR, responsive to an initiation of a communication session from an alternate transmission transmitter (ATT), sending the digital certificate to the ATT using the alternate transmission method; at the ATT, extracting the original transmission identity from the certificate and sending it to the original transmission transmitter (OTT) using the original transmission method for checking in a revocation list; and if the OT identity is found to be in the revocation list, preventing copy protected content from being sent from the OTT. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

摘要： One embodiment provides a method and apparatus for obtaining metadata program information during channel changes. The method includes the capture of an on-screen display that is rendered by a rendering device such as, for example, a digital television system. The on-screen display may be generated by an access device such as a set-top box in response to a program selection event. Once captured, the on-screen display may be decoded to determine metadata for a program selected by the program selection event. In one embodiment, decoding may be provided using pattern matching, optical code recognition (OCR) or other like decoding technique for decoding a video frame to determine metadata for a program selected by the program selection event. In one embodiment, a copy of the program in conjunction with the captured metadata are stored within the persistent memory of a digital television device. Other embodiments are described and claimed.

摘要： According to one embodiment of the invention, the descrambler IC comprises a local memory to store a unique key and a plurality of process blocks. A first process block is adapted to perform cryptographic operations on input information using the unique key to produce a user key. A second process block is adapted to perform cryptographic operations on incoming information using the user key to produce a copy protection key while a third process block uses the unique key to decrypt an encrypted descrambling key and recover the descrambling key. The decryption logic uses the descrambling key to decrypt encrypted incoming digital content and produce digital content in a clear format. The encryption logic uses the copy protection key to re-encrypt the digital content in the clear format and produce encrypted digital content for transmission from the descrambler.

摘要： A system and method for identifying the player that leaked content encryption keys by loading a set of player keys into individual content players and determining the number of encryptions and the number of encryption keys to use in multiple encrypting critical content. The method produces copies of critical data content packets, each copy of which is separately encrypted using any one of a set of encryption keys that are related to one another through a mathematical algorithm. The related set of encryption keys and data describing key relationship and content player identity are transmitted to a previously determined license management agency. The transmitted encrypted content is written to a receiving device or file, or streamed to an individual player for non-synchronous playback. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

摘要： A method of sharing keys among a plurality of conditional access (CA) vendors having differing CA systems used at a distribution headend involves receiving a CA Value contribution from each of the plurality of CA vendors at the headend; hashing the CA Values from each of the plurality of CA vendors together using a hashing function to produce an output control word; and at an encrypter at the headend, using the output control word as a content key, wherein the content key is used as an encryption key to encrypt content provided to a plurality of receivers that decrypt the content using any of the conditional access systems. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
