The SDR-9000 receiver is available from the VPC factory with one of three operating modes: MPE, MPEG/PID and SCPC. For multi-user data distribution networks using PC's or other workstations, Multiprotocol Encapsulation is an excellent choice. Data access is through any compatible browser software, including Microsoft Internet Explorer or Netscape Navigator, reducing the need for expensive customized software solutions. The MPE conforms to the appropriate international standards, including EN 301 192 within the MPEG transport stream.
The SDR-9000 also has the capability to operate in the encapsulated PID mode, sharing a digital stream with other MPEG services. The DVB-formatted Reed-Solomon FEC provides a significant performance advantage over other SCPC receiver systems with Viterbi-only FEC, and a significant advantage over non-DVB/Reed systems as well. The SCPC mode operates from a minimum speed of 1.5 Mb/sec to 20 Mb/sec.
To help recognize and diagnose any installation or operational problems, the SDR-9000 is equipped with a front panel diagnostic system using LED diagnostic indicators and a liquid crystal (LCD) display. Front panel LED's show: Cable Fault, which identifies potential failure problems in the coaxial cable lead-in from the LNB; LNB Connect, which shows electrical continuity between the satellite receiver and LNB; and Data Output, which indicates presence of actual data output.
The LCD display shows the following items: Signal acquisition, "Searching for Signal;" Data acquisition, "Not receiving Data;" and Data Quality (Excellent, Good, Fair, Poor) based on actual received bit error rate and PID control (optional at no charge depending on network operator preference). Operational features include: a serial input that permits programming channels to receive data in 1-bit per second increments (SCPC Mode) and control other operating parameters; various Viterbi FEC rates; L-Band frequency settings from 950 MHz to 2,150 MHz; MPE decoding; PID selection where specified; automatic power supply protection; DVB-formatted Reed-Solomon FEC; RS-232 or RS-422 data output, Ethernet or MPE/Ethernet; available rack mount; FCC/CE certified.
