Newtec AZ910 SNG Contribution Modulator
Newtec AZ910 SNG Contribution Modulator is a highly sophisticated, state-of-the-art satellite modulator that's designed for broadcast contribution, Satellite News Gathering
(SNG) and Primary distribution applications over satellite in full
compliance with DVB standards.
In its default configuration, the AZ910 is capable to demodulate
one MPEG transport stream in DVB-S, DVB-SNG or DVB-S2
mode and to interface with terrestrial broadcast network
through a standard ASI interface. Optionally, an optical ASI
interface can be added. BISSM descrambling option can be
activated to descramble Multiple program streams
To simplify the migration towards IP, the AZ910 is also available
with DualFlow (combined ASI+Ethernet interface), providing
broadcasters the following capabilities:
- The ability to demodulate Multistream and VCM carriers,
and to output up to two transport streams and one IP
stream simultaneously.
- The ability to interface (via a GbE output) with equipment
or networks that accept transport streams carried over IP
with the RTP protocol
- The ability to receive IP services (fi le transfers, VoIP, TCP
services…) simultaneously or alternatively with transport
stream(s). In this case the demodulator also performs the
extraction of the IP packets encapsulated in MPE or XPE
mode.
The AZ910 has a dual L-band input (950-2150 MHz). The
active input is selected by the user and can provide DC power
and frequency band selection signals compatible with most
professional and commercial LNBs. Optionally, one L-band input
can be replaced by an IF (50-180 MHz) input.
The AZ910 is equipped with an adaptive equalizer to
compensates linear distortion of the transmission channel.
The integrated Noise & Distortion Estimator tool provides an
accurate reading of the satellite link margin even in presence of
non-linear distortion and allows the user to fi nd the optimum
input back-off setting very easily for 16APSK or 32APSK
operation, whether or not non-linear predistortion is applied .
