2.4 Description
The cassette is a DVB-T / SPTS converter which combines COFDM-modulated
services (programmes) and transport streams supplied via the ASI interface
into one transport stream in the TPS module. This is emitted via the LAN inter-
face and can contain up to 16 services. For operating the cassette in a LAN
network it can be assigned its own IP address. The cassette is equipped with
two tuners. The accompanying channel strips consist of the digital tuners and
the digital signal processing levels. The resulting transport streams from the
“
Tuner A
”/“
Tuner B
” channel strips and from the transport streams supplied
via the ASI socket (ASI – Asynchronous Serial Interface according to DIN EN
50083-9) can take up to 16 services and are each assigned an IP address. The
signal supplied into the ASI input is provided again via the ASI output.
