Satellite signal distribution over a single coaxial cable - Second generation
|Publication Date:||1 March 2015|
|ICS Code (Cabled distribution systems):||33.060.40|
This European Standard describes:
▪ the system physical structure;
▪ the system control signals, which implement a set of messages using DiSEqC physical layer but not the DiSEqC message structure;
▪ the definition of identified configurations;
▪ the management of the potential collisions in the control signals traffic.
Figure 1 illustrates the physical system configuration considered in this standard.
Several satellite signal demodulators can receive signals from any of the input signal banks (Bank 1, Bank 2, Bank M, with M ≤ 256) of the LNB or the switch. The signals selected by the demodulators (or receivers) are transported via a single cable to these demodulators (Receiver 1, Receiver 2, Receiver N, with N ≤ 32).
To achieve these single cable distributions, the Single Cable Interface (SCIF, likely embedded in a LNB or a Switch) features some specific functions and characteristics.
