Earth Station Satellite Modulator , Uplink Station Satellite Communication Modulator

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 IRDs 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 (combined ASI+Ethernet interface), providing broadcasters the following capabilities:

- The ability to transmit two transport streams simultaneously in DVB-S2 Multistream mode (via a second ASI input).

- The ability to interface (via a GbE input) with equipment or networks that carry transport streams over IP with the RTP or UDP protocols. The IP layer is removed by the modulator before transmission.

- The ability to transmit IP services (file transfers, VoIP, TCP services…) and transport stream(s) simultaneously. In this case the modulator performs the encapsulation of the IP data in XPE  mode - The ability to transmit IP services or transport stream(s) alternatively.  In this case the modulator performs the encapsulation of the IP data in XPE  or MPE mode.

- The ability to configure Quality of Service (QoS) of the IP traffic, while keeping absolute priority to the ASI streams When several transport streams and/or IP services are transmitted simultaneously, the Variable Coding and Modulation (VCM) option allows each stream to be modulated with its own parameters.

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.
