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.
Features
Benefits
Combines a configurable DVB-C/DVB-T
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 for either DVB-C or
DVB-T networks

PCI
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
