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.

Features

Benefits

Combines a QAM demodulator with STB

decoding and display functions

This highly integrated SoC helps to reduce board

area and manufacturing cost, allowing low-cost

and small size STBs to be designed.

ST40 applications CPU,

32K I cache, 32K D cache

Superscalar performance from a single CPU core,

using standard tools and operating systems (Linux,

OS21).

STMicroelectronics' video decoding system

Decoding of advanced high definition standards for

MPEG2, H264, VC-1 broadcast, with the

performance and flexibility for web-based content

decoding such as Flash, DivX, MJPEG and Real.

Dual USB 2.0 hosts, e-SATA,

Ethernet MAC with MII/RMII and TMII,

interfaces, PCI interface

Extensive high speed connectivity for the widest

range of STB peripherals, such as Flash drives,

external HDDs, home network controllers (for

example MoCA, Wi-Fi), DOCSIS modem and so

on.

Low-power process, design and architecture

Best-in-class, low-power standby mode, to meet

emerging energy standards for STBs. Dynamic

configuration of power to individual sub-systems

enables power-efficient active standby modes.

Advanced 2D graphics and display subsystem

which also supports 3D user interface effects

and 1080p60 display output

Allows visually appealing user interfaces and video

rich navigation to be offered to consumers, while

high quality progressive output can be watched on

the latest high-definition displays.
