Overview
Advantech Wireless’ SBM75e Satellite Broadcast Modulator is
designed for the transmission of industry standard Digital Video
Broadcasting over Satellite (DVB-S/S2/DSNG).
New DVB-S2 modes of operation, such as Variable Coding
Modulation (VCM), further improve carrier efficiency by
permitting multiple modulation and coding combinations
within the same carrier. VCM operation is targeted at MultiStreaming modes of operation where more than one
Transport Stream can occupy a single carrier. Each
Transport Stream can be transmitted with different
modulation and coding combinations to maximize channel
efficiency.
Application
The SBM75e is designed to provide best in class
performance for critical applications such as:



For all broadcast applications, the fully featured SBM75e modulator
offers unrivalled flexibility supporting DVB-S2 LDPC + BCH coding,
SHORT and NORMAL FEC frame, Constant Coding Modulation
(CCM), Variable Coding and Modulation (VCM) and Adaptive Coding
and Modulation (ACM) modes of operation, and performance up to 45
Msys. The SBM75e also supports legacy DVB-S and DVB-DSNG
standards.
DVB-S2 is the latest standard targeted and optimized for broadcast
applications. With a wide range of modulation and coding options, it
permits broadcasters to achieve optimal efficiency. DVB-S2 offers
performance gains of up to 2.5dB compared to DVB-S systems. This
translates, approximately, to a 30% performance increase in a given
transponder bandwidth. This performance gain can be used to
increase the data throughput in a given transponder bandwidth,
provide more link margin or even to reduce antenna size.
