    Abstract: Various arrangements for encrypting multiple television channels are presented. A first television channel of a plurality of television channels to be protected via a first entitlement control message (ECM) using a first encryption scheme may be designated. The plurality of television channels may be transmitted using a single transponder stream. A second television channel of the plurality of television channels to be protected via a second ECM encrypted using a second encryption scheme while the first television channel of the plurality of television channels is protected using the first encryption scheme may be designated. The first and second ECMs may be transmitted to a plurality of television receivers. Data from the first ECM may be used for descrambling of the first television channel by the plurality of television receivers. Data from the second ECM may be used for descrambling of the second television channel by the plurality of television receivers.

    Abstract: Various arrangements for descrambling multiple television channels concurrently are presented. A set-top box may receive a first plurality of television channels as scrambled data packets. A previously-received locally-stored networking information table may be accessed that associates each of the multiple television channels with the same entitlement control message, as indicated by a packet identifier. An entitlement control message having the same packet identifier may be received. A smartcard may be used to decrypt the entitlement control message having the same packet identifier to obtain a first control word and a second control word. Scrambled data packets corresponding to the multiple television channels may be descrambled using the first control word and the second control word. These television channels may be stored and/or output for presentation by the set-top box.

    Abstract: A method for providing a user of a target device with placeshifted content. The method includes detecting, utilizing the target device, a matrix code associated with an audio/visual program. Data encoded in the matrix code includes program identifying information and elapsed time information with respect to the program. The method further includes generating, utilizing the target device, a request for the program based at least in part on the encoded data. The method also includes transmitting, utilizing the target device, the program request across a network.
