The follwing service information is carried via the ASTRA satellite network:
NIT (Network Information Table) are transmitted on each ASTRA-transponder
with DVB-signals. NIT carries the dynamically updated network and
transponder specific information (frequenzies, code rates etc.) for all
transponders of the network. NIT is transmitted every 10 seconds.
