DSNG (we currently have 6 Digital Satellite News Gathering Units)

All about DSNG

A digital satellite news gathering unit (DSNG) is a transmission unit/van, used mainly for live events, for broadcast purposes. These vans/units are used for quick deployments. SABC TVOB has 5 DSNG units plus an ENG (Electronic News Gathering Unit), all in JHB, except for one CPT-based DSNG van. These are all wired to carry 2 cameras, but one is mostly used, and as such is referred to as a single camera unit (SCU). That it is called a news gathering unit does not limit it to news productions, but every live production is possible as a result of a DSNG‘s connectivity. It can be referred to as a satellite transceiver; as it receives and also transmits.  A final output from the OB van goes to the DSNG for transmission. A DSNG unit has to always be there for a live transmission. A cameraman and a technician or 2 are required to operate this unit.
