Description
STi7108 is the next generation of HD, AVC set-top
box decoder for satellite, cable, terrestrial and
IP-STB markets.
The STi7108 provides a solution for operators to
specify a range of high-performance, MPEG2 /
H.264 / VC-1 STBs.
The STi7108 can be used with zappers, IP
clients, DVR standalone, and DVR server/home
network STBs, especially where true 3D graphics
is required.
Content delivery is possible using broadcast or
broadband networks, or both (hybrid STBs).
The STi7108 is also targeted at next generation
DLNA compatible Blu-ray (BD) and HD Media
players.

Introduction STi7108
1 Introduction
The STi7108 integrates in a single IC, multi-stream transport demultiplexing, an applications
CPU, a real-time CPU, A/V decode, video processing, true 3D graphics and display,
advanced security, STB peripherals, audio/video DACs, digital A/V outputs, HDMI, dual
eSATA ports, triple USB ports, dual Ethernet controllers (GbE capable) and an
SDIO/SD-MMC card controller.
Features Benefits
ST40 applications CPU, ST40 real-time CPU,
ST231 applications co-processor. Each CPU
has 32KI and 32K L1 caches with 256K L2
cache for the ST40 applications CPU.
Integrated graphics processing unit (GPU).
Programmable Vertex (geometry) processor and
fragment (pixel) processor, accelerated four
times full scene anti-aliasing (4 × FSAA).
Latest generation of ST's video decoder with an
ST231-based controller.
The high performance ST40 CPU for applications
and middleware, is enhanced by a real-time
companion ST40. The real-time ST40 off loads a/v
management and network protocols. The
applications CPU is complemented by a coprocessor, for multimedia processing and
security/DRM in home networks. Each ST40 works
with the ST231 to deliver unparalleled CPU
performance from a single STB SoC.
True 3D graphics and 2D vector graphics
acceleration, optimized for HD consumer digital
video applications. Compatible with the latest Open
GL ES 1.1/2.0 and OpenVG 1.1 libraries, for bestin-class 3D graphics effects/games, font rendering
and Adobe Flash support. Open GL ES 2.x ready.
Decoded HD video can be used as textures for
visually enhanced, video rich navigation guides
and user interfaces, and provides a platform for 3D
gaming.
Decoding of advanced high definition standards for
broadcast (MPEG2, H264, VC-1, AVS) plus the
performance and flexibility for web-based content
decoding such as Flash, DivX, MJPEG and Real.
New capabilities such as, Dual H264 HP@L4.1
decoding for HD PIP, and video-video transition
effects, decoding of H264 HP@L4.2 (1080p50,
1080p60 decoding) and premium rescaling
techniques open the way for high quality viewing of
enhanced HD services on the latest generation of
TVs.
Latest generation transport/security subsystem,
with enhanced performance for DVR
client/server-based home networks.
Triple USB 2.0 hosts, dual e-SATA, Dual
Ethernet MAC with MII/RMII/TMII/GMII
interfaces, PCI, SD-MMC/SDIO interface.
2/4 Doc ID 16790 Rev 3
Multi-stream transport demultiplexing,
descrambling and section/data filtering. Up to 6 live
TS inputs supported.
Extensive high speed connectivity for the widest
range of STB peripherals, such as Flash drives,
external HDDs, Gigabit Ethernet, home network
controllers (for example, MoCA, WiFi), DOCSIS
modem and memory cards.
