Description
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
DirecTV^TM transmission standards.
