    摘要: An interface adapter device consistent with certain embodiments has a first electrical connector adapted to connect to a conditional access service card to receive encrypted television signals therefrom. A second electrical connector is adapted to connect to a television receiver device in order to provide the encrypted television signals to the television receiver device. An interface circuit receives the encrypted television signals from the first electrical connector and adapts the signals for transmission to a television receiver device over the second electrical connector. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

    摘要: A selective encryption decoder for decrypting and decoding a selectively encrypted digital video signal has a demultiplexer that receives packets of digital video, certain of the packets being unencrypted and certain of the packets being encrypted. Certain of the encrypted packets carry data representing an active region of a video frame. The unencrypted packets have a first packet identifier (PID) and the encrypted packets have a second packet identifier (PID). A decrypter receives the encrypted packets having the second PID and decrypts the encrypted packets using a first encryption method to produce decrypted packets. A PID remapper changes at least one of the first and second PIDs so that the unencrypted packets and the decrypted packets have the same PID. A decoder decodes the unencrypted and decrypted packets to produce a decoded video signal. This abstract is not to be considered limiting since other embodiments can include more, fewer or different features than those described in this abstract.

    摘要: An electronic storage device facilitates transmission or reception of multiple partial encrypted digital video has a segment of digital video content recorded on the electronic storage device as a data structure with a first set of data packets encrypted under a first encryption process so that the first set of data packets can be decrypted by a first decryption process; a second set of data packets encrypted under a second encryption process so that the second set of data packets can be decrypted under a second decryption process. The first set of video data packets and the second set of video data packets, when unencrypted, represent duplicate copies of the same video information. A third set of data packets contains unencrypted video data that is contextually contiguous to the first set of data packets and the second set of data packets. The first set of data packets together with the third set of data packets represents all video content in the segment of digital video content as does the second set of data packets together with the third set of data packets. The data structure enables the first set, the second set, and the third set of digital video content to be read out of the electronic storage device in an order that facilitates decryption of the segment of digital video content by use of a decrypter having capabilities for decryption of encrypted information under the first decryption or by use of a decrypter having capabilities for decryption of encrypted information under the second decryption process, at either a transmission facility or a receiver.

    摘要: A method of content substitution involves receiving an ordered stream of packets containing content marked by a first packet identifier (PID) and one or more substitute content portions marked by one or more secondary PIDs, where the number and placement of packets marked by secondary PIDs ahead of packets marked by the first PID in the stream is retained during transmission of the ordered stream of packets; initiating processing for display or storage of content contained in packets having the first PID; initiating processing for display or storage of content contained in packets having a selected secondary PID that meets a substitution criterion; and either deleting or processing the content having the first PID depending upon a number of received intervening packets having secondary PIDs that reside between the packets having the first PID and the packets having the selected secondary PID that meets the substitution criterion. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
