Overview

Advantech’s AMt 75 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 AMT 75 is the Satellite Broadcast receiver (SBR75) which is a low-profi le embedded card in a compact form. For all broadcast applications, this fully featured Demodulator offers unrivalled fl exibility supporting DVB-S2 LDPC coded data rates of up to 130 Mbps in a 36 MHz channel using 32APSK (110 Mbps using 16APSK or 80 Mbps using 8PSK, respectively in a 36Mhz transponder). The card supports both the SHORT FEC frame and the NORMAL FEC frame. The SHORT frame is particularly useful to minimize latency in low data rate contribution applications. This card can also be specifi ed with DVB-S and DVB-DSNG 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 can be translated to approximately a 30% capacity increase in a given transponder bandwidth. This performance gain can be used to either increase the data throughput via a given Satellite bandwidth, therefore signifi cantly reducing transponder costs, to provide more link margin or even to reduce antenna size. The card also supports new DVB-S2 modes of operation, such as Variable Coding Modulation (VCM) and Adaptive Coding Modulations (ACM), which further improve available throughput on given satellite channels. The performance benefi ts, reliability and interoperability of standards based DVB-S2 makes it the ideal solution for broadcasters considering implementing new services or upgrades current deployed 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. 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 AMT75 can support up to 3 SBR75 in distinct and/or redundant formation within a 1RU chassis providing compact solution for multi receiver applications.

Applications

• The SBR75/AMT75 is designed to provide best in class performance for critical applications such as:
• Digital Video Broadcast (DVB)
• Digital Satellite News Gathering (DSNG)
• Business enterprise data distribution (ultra high speed IP delivery, e-learning, streaming video and audio)
• Distribution of Digital Terrestrial Transmission
