| 摘要 |
The present invention relates to a system and a device for providing proximity control in a satellite television media content distribution system comprising at least a primary receiver and a secondary receiver, whereby authorisation to access the conditional access media content is given if the primary and secondary receivers are verified to be within a single household. The invention uses LNB control signaling, by the primary receiver, to cause the LNB to down-convert signals from pre-determined transponders onto a pre-determined frequency in the L-Band such that the secondary receiver may receive messages thus created through the primary receiver's controlling of the LNB. |
