摘要： A method of encrypting a digital television signal carried out in any operative order involves duplicating packets in the digital television signal so as to create first and second duplicate packets; encrypting the first duplicate packets according to a first encryption method to create first encrypted packets; encrypting the second duplicate packets according to a second encryption method to create second encrypted packets; identifying packets in the digital television signal that are of a packet type, while other packets are not of the packet type; replacing the identified packets in the digital television signal with corresponding first and second encrypted packets to produce a multiple partially encrypted digital television signal comprising the other packets that are unencrypted and the first and second encrypted packets; and distributing the multiple partially encrypted digital television signal. This abstract is not to be considered limiting as other embodiments may include more or fewer or differing elements than appear in the abstract.

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. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

摘要： A television content delivery system consistent with certain embodiments has a receiver system that receives television content from a plurality of content suppliers. A selective multiple encrypter selectively multiple encrypts the television content, wherein the resultant selectively multiple encrypted content stream is encrypted under at least one conditional access system (CAS) and at least one digital rights management system (DRMS). A transmitter transmits the selectively multiple encrypted television content stream to multiple receivers, so that the selectively multiple encrypted television content stream can be decrypted under either a system using at least one CAS or at least one DRMS.
