HD cable/terrestrial STB processor with integrated demodulators and low power standby controller
  • active Active

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.
