Description
The STiH273 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 cable and terrestrial networks, and is
suitable for operator markets (with advanced
security) and retail markets worldwide.
The STiH273 provides a solution for operators
and manufacturers to specify a range of cost-
effective, high performance STBs, including basic
zappers, interactive STBs, and DVR STBs with
content delivery possible using broadcast or
broadband networks or both (hybrid STBs).
The STiH273 integrates a high performance dual
mode, cable/terrestrial receiver, supporting
DVB-C or DVB-T reception, channel
demodulation, and forward error correction (FEC).
The DVB-C receiver is compliant with ITU-T J.83
Annex A/C, and the DVB-T receiver is compliant
with ETSI EN-300744 v1.5.1, Nordig Unified
(v2.2.1) and DTG 7.2.
