Web GUI Monitoring & Control

Consequently, streams borne on frames with less robust modulation and/or coding may be

prevented from contaminating other more robust streams. But it must be remembered that

occasional un-corrected transmission errors on a robust stream will result in the loss of entire base-

band frames.

4.9.3.3 PLS Seed

The DVB-S2 physical layer specification makes provision for the application of user specific

physical layer scrambling.

User specific physical layer scrambling may be applied by entering the appropriate value in the

PLS Seed Text box on the advanced window. The value of the seed entered must match the

value of the seed employed at the corresponding modulator.

4.9.4 Profiles

This option allows the user to save and recall a variety of operational profiles and exchange

profiles between different chassis via a host computer.

This facility may be used by selecting the Profiles tab from the main configuration window. A

window, similar to that shown in Figure 4.34 is displayed.
