Around 1996 and 1997 many operators started using the successful
DVB-S (EN 300 421) standard for the delivery of occasional D-SNG
(Digital Satellite News Gathering) services over satellites.
While not specifically designed for such operations, the DVB-S
standard performed quite well. This practical implementation led to DVB
adding extensions to DVB-S, DVB-SI (EN 300 468) and MPEG (TR 101
154) to provide support for these services.
The DVB-DSNG group was formed and produced the following DVB standards:
Three application areas by satellite are considered:
- EN 301 210 V1.1.1 (02/99) Framing structure,
channel coding and modulation for Digital Satellite News Gathering
(DSNG) and other contribution applications by satellite
- TR 101 221 V1.1.1 (03/99) User guideline for
Digital Satellite News Gathering (DSNG) and other contribution
applications by satellite
- EN 301 222 V1.1.1 (07/99) Co-ordination channels associated with Digital Satellite News Gathering (DSNG)
The DVB-DSNG activities have largely been superseded by the DVB-S2 activity.
