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.

SDT (Service Description Table) is carried on the two Barker channel (V/H). 
A Barker channel is a private data stream within a DVB/MPEG-2 multiplex. SDT

every 2 seconds.
