How DSNG system works?
DSNG stands for Digital Satellite News
Gathering. DSNG system is used as mobile earth station. To perform live
broadcasting from a remote place where any physical link like optical
fiber, transmission wire, radio link are not available, then the
satellite link is the only way to send the raw footage to the main TV
station. The DSNG system is approximately similar to the earth station
system together with a mini program control system. The signal flow in
the DSNG system as like as below.

TV station can use the same satellite or
different satellite for main up-link and DSNG system. After
transmitting the raw footage by DSNG, main station receives that signal.
Now it comes to the base band section, processed and then made ready
for final on-air through the main up-link.
