Single-chip controllers enable
advanced STB products
IBM STB03xxx digital set-top box inte-
grated controllers provide single-chip,
high-performance solutions for digital
video broadcasting (DVB), digital record-
ing, and demanding video delivery
applications, including interactive Web
browsing. New members of IBM's family of
STB products, these advanced controllers
incorporate an IBM PowerPC 405
TM
processor within IBM's STB architecture.
Featuring IBM Blue Logic
TM
technology
and manufactured using IBM's advanced
0.25-micron process, the STB03xxx
controllers incorporate four powerful
subsystems -- processor, digital audio/
video, peripheral and memory interface.
The efficient STB03xxx controller design
makes more MIPS available to STB
manufacturers by allowing the base audio
and video decoding activities to execute
with minimal host processing. A unified
memory architecture provides configura-
Highlights
tion flexibility. The advanced features of
STB03xxx controllers include:
Integrated PowerPC 405 processor
MPEG-2 audio/video decoder
Dolby
Digital audio decoder option*
(IBM STB0321x and STB0341x only)
MPEG-2 transport demultiplexer
On-screen display controller
NTSC/PAL digital encoder
IDE interface for hard disk drive (HDD),
smart card, parallel and serial ports
Design flexibility supports
diverse applications
Designers have the flexibility to choose
from a range of STB03xxx controllers to
satisfy their individual application
requirements. They can choose a
controller with an embedded PowerPC
405 featuring either 150-MIPS or 225-
MIPS performance. In addition, they have
the flexibility to select a controller with
Macrovision Copy Protection
support,
Dolby Digital audio support or both. The
new IDE interface and anti-flicker-filter
feature allow easier enablement of digital
video recording and Web browsing
applications.
PowerPC 405 delivers high
performance
The PowerPC 405 processor, the heart of
the processor subsystem, features high-
speed operation at 108 MHz or 162 MHz,
a 16-KB instruction cache and an 8-KB
data cache to enhance overall applica-
tion performance. With this processing
capability, products can support elec-
tronic programming guides, e-commerce
applications, Web browsing and other
interactive applications.
Digital audio and video capabili-
ties support next-generation
applications
The digital audio and video subsystem
delivers high-quality video and sound,
enabling service providers to offer
graphically rich user interfaces for next-
generation interactive applications. The
digital audio and video subsystem
incorporates:
MPEG-2 video decoder with anti-flicker
filter and five on-screen display (OSD)/
video planes; decodes MPEG-2 Main
Profile at Main Level (MP @ ML) video
MPEG-2 transport and DVB descrambler
MPEG-2 audio decoder; decodes
MPEG-2 Layer I & Layer II (CD quality)
audio
Dolby Digital-compliant decoding (IBM
STB03x1x controllers only; a Dolby
Digital license is required)
Digital encoder, including NTSC/PAL
analog conversion, six concurrent analog
video outputs and compatibility with
SCART connectors
STB03xxx controllers provide single-
chip, high-performance solutions.
