    Abstract: An arrangement for grouping multiple television channels for recording is presented. Television channel usage data indicative of television programs being requested by users of the television receivers may be received. The television channel usage data may provide usage data for television channels being transmitted using a plurality of transponders. The television channel usage data may be analyzed to determine a grouping of television channels. Based on the television channel usage data, a television channel may be reassigned from a first transponder to a second transponder for transmission to the plurality of television receivers such that the grouping of television channels are transmitted using the second transponder.

    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.
