Introduction

The STiH246 uses state-of-the-art process technology to provide fully featured HD AVC

decoder IC. It is a highly integrated system-on-chip suitable for STB markets across all

networks (satellite/IP/terrestrial/x-DSL) worldwide.

The STiH246 is targeted at the latest Operator and CE manufacturer requirements for STBs

which utilize advanced HD decoding (H264/VC-1/MPEG2), and which conform to DVB,

ISMA, ATIS-IIF, SCTE, DirecTV, ATSC, ARIB, CEA, ITU, OpenCable and MSTV

specifications.

The STiH246 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 STiH246

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 STiH246 offers current users of STs growing family of advanced decoding ICs

enhancements in performance and features whilst reducing cost and time-to-market for the

next generation deployments.

Features

Benefits

Superscalar performance from a single CPU core,

using standard tools and operating systems (Linux,

Windows CE, OS21)

Supports 3D side-by-side and 3D effect user

interface

Decoding of advanced standard definition MPEG2,

H264 and VC-1/WMV9 streams, with the

performance and flexibility for web-based content

decoding such as Flash, DivX, MJPEG, XviD and

Real

Advanced 2D graphics and display subsystem,

and 1080p 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 displays

Dual USB 2.0 hosts, Ethernet MAC with

MII/RMII and TMII, SD-MMC/SDIO

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), memory cards

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 subsystems

enables power-efficient active standby modes
