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
