Introduction STi5206
1 Introduction
The STi5206 is targeted at the latest operator and CE manufacturer requirements for STB
markets across all networks (cable/satellite/DTT/x-DSL/IP) worldwide.
The STi5206 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
possible using satellite broadcast or broadband networks, or both (Hybrid STBs).
The STi5206 is optimized for secure Pay-TV applications with integrated DVB, DES, AES,
Multi-2 and ICAM descramblers and smartcard interfaces.
The STi5206 offers enhancements in performance, features and integration to current users
of ST’s SD AVC family of audio/video decoders, while reducing cost and time-to-market for
the next generation deployments.
