SATELLITE BROADCAST SIGNAL RECEIVER, METHOD OF OPERATION OF SATELLITE BROADCAST SIGNAL RECEIVERS AND SWITCH THEREFOR

摘要

A plurality of satellite broadcast signal receivers (10) are connected in series to a low-noise block downconverter, LNB (22), of a satellite dish and operate according to single cable distribution. One of the receivers (10) transmits a control signal ultimately to be received by the LNB (22) to select a channel to be received from the LNB (22) for the receiver (10). If the one receiver (10) is the first receiver (10₁) in the series connection of receivers to the LNB (22), the one receiver (10₁) transmits the control signal to the LNB 2. Otherwise, if the one receiver (10) is further down the series connection of receivers (10) to the LNB (22), the one receiver (10_x) transmits the control signal to another receiver (10_x-1) that is further up the series connection of receivers (10) to the LNB (22) for that other receiver to pass on the control signal for the control signal to be received ultimately by the LNB (22).
