Role of the Modulator
The Modulator is designed specifically for the broadcasting of digital
satellite television signals to ETSI standards EN 300 421 (DVB-S) and
EN 301 210 (DVB-DSNG).
The unit is designed for the transmission of MPEG-2 digitally-compressed
video, audio and data services provided by the evolution 5000 range of
products, although it could be used with other types of equipment
providing the specification is compatible (see Annex B, Technical
Specification). The input data interfaces to the unit conform to the DVB
Asynchronous Serial Interface (DVB ASI) standard, and optionally the DVB
Synchronous Parallel Interface (DVB SPI) standard if the
SM66XX/HWO/ASI-SPI option is fitted.
The Modulator can be configured by its front panel, a VT100 terminal, or a
PC running a terminal emulator (see Figure 1.3). Alternatively, the
Modulator may be controlled remotely, either via its Ethernet ports or
RS-232/485 port.
