Introduction
The
MO-480/481
is a broadcast grade
DVB-T/T2
modulator available in a
standard 1U high 19" rack case (
MO-480
) and also in an open frame chassis
(
MO-481
) that can be used for MFN as well as SFN applications.
The modulator has several
Transport Stream
and
T2-MI
inputs in ASI and IP
formats so that it can be easily interfaced with other existing transmission
equipments such as gateways. The modulator can be configured to generate any
of the transmission modes listed in the corresponding
DVB-T2
standard
including single and multiple
PLP
,
MISO
or
SISO
. It can also be used for DVB-T
applications.
The modulator inputs consist of an
MPEG-2
transport stream (TS) in
TS over IP
or
DVB-ASI
format, a 10 MHz GPS reference and a 1pps GPS reference. The
GPS inputs are for SFN synchronisation purposes. The outputs are
DVB-T/T2
signals COFDM-modulated and up-converted to RF.
The interest in
DVB-T2
is now increasing with the growing demand for
bandwidth mostly to deliver high definition television programmes. Several
countries already have T2 commercial services, some others are running test
trials and many more are on the planning stage.
