Introduction STi7102

1 Introduction

The STi7102 is targeted at the latest Operator and CE manufacturer requirements for STBs
that use advanced HD decoding (H264/VC-1/MPEG2). The STi7102 conforms to DVB,
ISMA, ATIS-IIF, SCTE, ATSC, ARIB, CEA, ITU, OpenCable and MSTV specifications.

The STi7102 provides a solution for operators to specify a range of cost-effective, high
performance HD STBs including zappers, IP clients, interactive STBs, DVR standalone and
DVR server STBs. Content delivery is possible using broadcast or broadband networks, or
both (hybrid STBs).

The STi7102 offers current users of ST’s growing family of advanced decoding ICs
enhancements in performance and features, while reducing cost and time-to-market for the
next generation deployments.
