Overview

Advantech Wireless’ SBM75e Satellite Broadcast Modulator is designed for the transmission of industry standard Digital Video Broadcasting over Satellite (DVB-S/S2/DSNG).

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.

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 Multi-Streaming 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:

  • Video Contribution Digital Satellite News Gathering (DSNG)
  • Primary Distribution of Digital Television for Mobile and Terrestrial applications
  • Direct To Home
