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 costeffective, 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.

Introduction	STiH273

1 Introduction

The STiH273 offers current users of ST’s growing family of advanced decoding ICs enhancements in performance and features, enabling operators to offer consumers new multimedia-rich services and viewing experiences, including new 3DTV features. Faster DDR3 memory is also supported, and the applications CPU benefits from an L2 cache. The STiH273 keeps pace with the latest advanced security requirements of the main CA vendors, and an integrated standby controller enables the STiH273 to target stringent low power regulations.

Features		Benefits
