Introduction STi7197
1 Introduction
The STi7197 is targeted at the latest operator and CE manufacturer requirements for STBs
that use advanced HD decoding (H264/VC-1/MPEG2). The STi7197 conforms to DVB,
ISMA, ATIS-IIF, SCTE, ATSC, ARIB, CEA, ITU and OpenCable specifications.
The STi7197 provides a solution for operators to specify a range of cost-effective, high
performance HD STBs including cost-effective zappers, IP clients, interactive STBs, DVR
standalone and DVR server/home network-capable STBs. Content delivery is possible using
broadcast or broadband networks, or both (hybrid STBs). The STi7197 incorporates the
latest generation of advanced security features.
The STi7197 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.
