Description
The AZ110 is a state-of-the-art satellite modulator designed for broadcast
contribution, DSNG and distribution applications over satellite in full compliance
with the DVB standards. Depending on the applications and the activated features,
the AZ110 can be used in conjunction with set-top boxes, professional integrated
receivers/decoders or satellite demodulators such as the AZ910.
In its default configuration, the AZ110 is capable of transmitting one MPEG
transport stream in DVB-S, DVB-DSNG or DVB-S2 mode. The AZ110 allows
automatic or manual selection between two ASI inputs and has dual ASI
monitoring outputs. Optionally, an optical ASI interface can be added.
To simplify the migration towards IP, the AZ110 is also available
with DualFlow.
Refer to the
User Manual for AZ110 Broadcast Satellite
Modulator with Dualflow Option
for more information.
To protect the satellite transmission, the BISS/BISSM or AES option can be
activated. BISS scrambles a single program transport stream, BISSM a multiple
program transport stream available on the ASI interface. AES allows to encrypt
with a high security level the content of all DVB-S2 streams. When activated, the
per stream mode allows to encrypt up to four S2 streams with individual keys.
At the output of the modulator, the signal is available on an L-band interface.
Extended L-band, IF- and RF-band as well as BUC power supply and reference
frequency are available as configuration options, providing a compact and cost
effective solution.
This modulator provides exceptional performance and bandwidth efficiency. When
activated, the unique linear and non- linear predistortion option Equalink™
provides an additional link margin improvement of up to 2,5dB, truly unleashing the
full efficiency of higher modulation schemes such as 16 and 32 APSK.
