Introduction STi7167

1 Introduction

The STi7167 is targeted at the latest Operator and CE manufacturer requirements for STBs that use advanced HD decoding (H264/VC-1/MPEG2), and which conform to DVB, ISMA, ATIS-IIF, SCTE, ATSC, ARIB, CEA, ITU, OpenCable and MSTV specifications.

The STi7167 provides a solution for operators to specify a range of low-cost, high performance HD STBs including low-cost zappers, IP clients, interactive STBs, DVR standalone and DVR server/home network-capable STBs, and with content delivery possible using broadcast or broadband networks, or both (hybrid STBs). The STi7167 keeps pace with the latest conditional access, DRM and trusted platform requirements of major operators worldwide by incorporating the latest generation of advanced security features.

The STi7167 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.
