Advantages compared to other SNG Systems:
Requires half of the satellite bandwidth compared to MPEG-2 systems at the same quality (2.25 MHz for news, 4.5 MHz for sports) Smaller and easier to use equipment Remote line-up feature via UMTS/ GSM (requires no satcom technicians in the field) Lower equipment and service costs Supports point-to-point uplinks and IP streaming
