Certain embodiments provide a set top box, comprising: a processing entity configured to obtain data for a channel stacking switch, to obtain a security data element and to formulate a message for the channel stacking switch by combining the security data element with the data; a communications interface configured to send the message to channel stacking switch. Other embodiments provide a channel stacking switch, comprising: a communication interface configured to receive a message from a set top box; a processing entity configured to determine whether or not the message is legitimate and to take an action that depends on whether or not the message is legitimate. Still further embodiments provide a satellite signal receiving system comprising a channel stacking switch and at least one set top box in secure communication with the channel stacking switch.

Signal security in a satellite signal distribution environment

A communications system and method involving a set top box (STB) and a channel stacking switch (CSS). The STB comprises a communications interface configured to issue a request for a user band, the request identifying the STB and further configured to receive a message identifying an assigned user band; and a tuning element configured to tune to the assigned user band in response to receipt of the message. The CSS comprises a communications interface configured to receive the request for a user band identifying the STB; a memory; and a processing entity configured to access the memory to identify a particular user band that is available for the STB and to assign the particular user band to the STB; wherein the communications interface is further configured to issue to the STB a message identifying the particular user band assigned to the STB.
