Description Technical Specs
 
The OM2000 produces an out-of-band (OOB) data stream to digital set-tops providing a signaling channel, transmission of program guide information, code downloads, infrared codes, application information and the downstream path in an interactive system. Data input is configurable through Ethernet and serial connections. The OM2000 Quadrature Phase Shift Key Modulator (QPSK) modulates data on a 1.5 MHz wide carrier in the 71 to 129 MHz band with transmitted data multiplexed either in the OM2000 or externally. Null packets are used as necessary to perform rate aggregation between its inputs and the 2.048 Mbps output. Forward error correction (FEC) encoding and interleaving protects data integrity.
