What is DSNG ?
A- Satellite news gathering (SNG) is the use of mobile communications equipment for the purpose of worldwide newscasting. Mobile units are usually vans equipped with advanced, two-way audio and video transmitters and receivers, using dish antennas that can be aimed geo-stationary satellites. The earliest SNG equipment used analog modulation similar to conventional television and radio. During the 1990s, digital modulation supplanted analog modulation, giving rise to the newer technology of digital satellite news gathering (DSNG). A modern DSNG van is a sophisticated affair, capable of deployment practically anywhere in the world. Signals are beamed between a geo-stationary satellite and the van, and between the satellite and a control room run by a broadcast station or network. In the most advanced systems, Internet Protocol, IP, is used. Broadcast engineers are currently working on designs remotely controlled, robotic DSNG vehicles that can be tele-operated in hostile environments suc
