Advantech’s SBD75e DVB-S/S2 Broadcast Receiver is designed for the reception and forwarding of digital television signals and/or transmission of high-speed data (IP) over industry standard Digital Video Broadcasting over Satellite (DVB-S/S2). At the heart of the SBD75e is the Satellite Broadcast receiver (SBR-75)which is a low profile embedded card in a compact form. For all broadcast applications, this fully featured Demodulator offers unrivalled flexibility supporting DVB-S2 LDPC + BCH coding, SHORT and NORMAL FEC frame, and up to 45 Msys. This card can also be specified with DVB-S and DVB-DNSG Pragmatic Trellis decoding allowing the demodulation of existing QPSK, 8PSK and 16QAM DVB-S and DVBDSNG PTCM signals. When used in DVB-S2 modes the card offers performance gains of up to 2.5dB compared to older 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 available throughput on given satellite channels. The performance benefits, reliability and interoperability of standarts based DVB-S2 makes it the ideal solution for broadcasters considering implementing new services or upgrades to current DVB-S networks. The SBR75 supports up to 4 DVB ASI ports, providing the means to de-multiplex and remap DVB MPEG Transport streams (TS) to individual ASI ports, from a single carrier or may also duplicate a single MPEG TS so that the output appears at both ASI outputs.. Additionally, an optional 10/100/1000BaseT interface is available providing the means to simultaneously support both ASI and Ethernet based data and video streams. The SBD75e can support up to 2 SBR75 in distinct and/or redundant formation within a 1RU chassis providing compact solution for multi receiver applications. Optionally, Advantech’s Media Gateway (MG) may be combined with the demodulator providing the AMT75 with advanced ASI, IP and media handling capabilities.
