HD satellite STB processor with integrated demodulator and low power standby controller
  • active Active

The STiH237 uses the latest process technology to provide a cost-effective, feature rich, highly integrated SoC for set-top boxes (STBs). It is targeted at the advanced decoding STB market across satellite networks, and is suitable for operator markets (with advanced security) and retail markets worldwide.

The STiH237 provides a solution for operators and manufacturers to specify a range of cost-effective, high performance zapper STBs, with content delivery possible using broadcast or broadband networks, or both (hybrid STBs).

The STiH237 integrates a high performance satellite receiver supporting DVB compliant reception, channel demodulation, and forward error correction (FEC). The single stream demodulator is compatible with DVB-S2 (QPSK/8PSK), DVB-S (QPSK) and legacy DirecTVTMtransmission standards.
