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.
