2. General functional description
The devices of the HDS family are MPEG encoders with integrated DVB modulator. Depending on the device type,
up to 4 SDI signals can be encoded and from these as well as an additional ASI transport stream up to 4 program
bouquets in DVB-C or up to 2 program bouquets in DVB-T can be compiled. The integrated modulator generates
DVB-compliant signals, which contain all necessary program and service tables (PAT, PMT and SDT). Similarly, a
NIT is generated. Furthermore, the output signals are available in parallel on an IP interface and on 2 ASI transport
stream outputs for further processing. The devices support the encoding of MPEG2 HD/SD and MPEG4/AVC H.264
HD/SD signals, which are supplied as SDI signals and ASI transport streams e.g. from receivers, decoders or cam-
eras.
Depending on the application, the devices are preconfigured on the hardware side. The operating parameters can be
adapted to the required application via the integrated user interface (keypad or web browser).
NOTE
After a power failure, all data is retained.
