Functional Description
Gold codes (also known as the "Gold Sequence Number") are built into the
functionality of DVB-S2 and are designed to randomize/scramble the Physical Layer
Frames just before being modulated to a DVB-S2 signal. To recover the scrambled
frames after demodulation, the same Gold code must be entered in the RX8000
configuration.
This randomization is used to reduce signal correlation within a satellite link. This
means the bandwidth of the satellite can be used in the most efficient manner. Also
this provides a rudimentary form of Conditional Access whereby only a downlink that
knows the Gold Code can use the Transport Stream.
To use this system, the Gold Code from the source modulator must be entered into
the RX8000 Gold Seq N (S2 Only) menu item on the Input > Sat Input > Input 1...4.
Note:
The Gold Code or Gold Sequence Number is a decimal number within the range 0 –
262141 and is only used when the input is in DVB-S2 mode (not DVB-S).
3-184
Description
A different Gold Code can be provided for each satellite input.
