Introduction	STi5197L, STi5197

1 Introduction

The STi5197 uses state-of-the-art process technology to provide an ultra low cost, full featured, SD set-top box SoC. It is a highly integrated solution combining QAM demodulation, audio/video decoding and applications processing into a single chip, suitable for MPEG2-based Cable networks worldwide.

The STi5197 provides a solution for operators to specify a range of low cost SD STBs including low cost Zappers, Interactive STBs and DVR-capable STBs, with content delivery using broadcast or broadband networks, or both (Hybrid STBs).

The STi5197 is optimized for secure Pay-TV applications with integrated DVB, DES, Multi2 and ICAM descramblers and smartcard interfaces.

The STi5197 offers enhancements in performance, features and integration to current users of ST’s MPEG2 SD family of audio/video decoders and QAM demodulators, whilst reducing cost and time-to-market for the next generation of deployments. Few external components are required to realize a complete STB solution, resulting in very low BOM cost.

Features
