摘要： A method and apparatus for content substitution, consistent with certain embodiments of the present invention involves receiving data representing content, the data having at least first and second packet identifiers (PIDs) associated with first and second portions of content. The content having the first PID is placed into a data stream. An initiation flag is received indicating initiation of a PID mapping operation. The content having the second PID is then mapped to the first PID and the mapped content is placed into the data stream. A termination flag is received indicating termination of the PID mapping operation at which point the process returns to placing content having the first PID into the data stream. The content substitution process can be used to replace advertisements, provide multiple plots, multiple endings, multiple views as well as other applications.

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.

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： A method and apparatus for content substitution, consistent with certain embodiments of the present invention involves receiving data representing one or more macroblocks of content, the data having at least first and second packet identifiers (PIDs) associated with first and second portions of content. The content having the first PID is placed into a data stream. An initiation flag is received indicating initiation of a PID mapping operation. The substitute macroblocks of content having the second PID is then mapped to the first PID and the mapped content is placed into the data stream. A termination flag is received indicating termination of the PID mapping operation at which point the process returns to placing content having the first PID into the data stream. The content substitution process can be used to replace advertisements, provide multiple plots, multiple endings, multiple views as well as other applications. This abstract should not be considered limiting, since other embodiments may incorporate more, fewer or different elements that those described in this abstract.
