Highlights
High integration and more DMIPS deliver
leading-edge capabilities
IBM STB04xxx and STBx5xxx Digital
Set-Top Box Integrated Controllers
provide manufacturers and service
providers with high-performance,
highly integrated semiconductors for
demanding set-top box (STB) applica-
tions, including PVR, VideoGuard
and
XTVTM from NDS, interactive TV, Web
browsing, and data broadcasting. The
newest members of the IBM family of
STB products, these advanced con-
trollers incorporate the IBM STB
architecture, advanced 0.15-micron pro-
cess technology, and design flexibility.
These controllers deliver high DMIPS
performance and robust functionality
geared to today's diverse and increas-
ingly large bandwidth requirements.

performance, the controllers integrate
a glueless integrated external
processor interface that enables dual-
processor solutions.
To support NDS conditional access
(VideoGuard) and XTV applications,
IBM offers controllers that comply with
these NDS services (STB15xxx).
Additionally, customers can select a
controller with Macrovision copy pro-
tection support, Dolby
Digital audio
support, or both. A broad spectrum of
peripheral interfaces and support for
a range of industry-standard memory
further extend design flexibility.
PowerPC 405 delivers high performance
The PowerPC 405 processor, the heart
of the processor subsystem, features
high-speed operation at 126 MHz or
252 MHz, 16-KB instruction cache, and
16-KB data cache to maximize appli-
cation performance. With this process-
ing capability, STB manufacturers can
design products to support:
PVR
Internet gaming
Interactive TV
Web browsing
E-commerce applications
Personal TV services (NDS XTV)
Advanced digital audio and video features
support next-generation and multi-stream
applications
The digital audio and video subsystem
delivers high-quality video and sound,
enabling state-of-the-art features for
consumer applications. An advanced
MPEG-2 transport demultiplexer func-
tion, including three demultiplexers
and multistreaming capabilities, sup-
ports simultaneous dual-stream
recording and single-stream playback.
Capabilities include playing a video
stream from an HDD, live streaming
of video, and variable video scaling.
In STB15xxx controllers, the transport
function also supports NDS conditional
access and XTV Services. The digital
audio and video subsystem operates
with minimal processor intervention,
making more DMIPS available for cus-
tom application functions.
The STB04xxx and STBx5xxx
digital audio and video subsystem
incorporates:
MPEG-2 video decoder; decodes
MPEG-2 Main Profile at Main Level
(MP@ML) video
Three MPEG-2 transport
demultiplexers/DVB descramblers
(DES encode and decode in
STB05xxx and STB15xxx controllers)
Digital encoders, including NTSC,
PAL, and SECAM analog conversion,
and six concurrent analog video
outputs
MPEG-2 audio decoder; decodes
MPEG-2 Layer I & Layer II
MPEG-2 Layer III (MP3) audio
decoder
Dolby Digital-compliant decoding*
(STB04x1x and STBx5x1x
controllers only; Dolby Digital
license is required)
Macrovision copy protection support
(STB04xx1 and STBx5xx1 controllers
only; a Macrovision license is
required)
Support for NDS VideoGuard and
NDS XTV (STB15xxx controllers only;
an NDS license is required)
High performance and support for
multiple transport inputs and memory
streaming enable solutions such as
dual tuners and HDD applications.
The solution is designed to enable
middleware environments, such as
MediaHighway, which facilitate STB
services, including live broadcasts and
storing and receiving video and audio.
The IBM PowerPC ArchitectureTM pro-
vides a clear software migration path to
high-performance processors for more
demanding applications. In addition,
IBM's enabling tools can help STB man-
ufacturers improve their time-to-market.
The STB04xxx and STBx5xxx design
allows base audio and video decoding
activities to execute with minimal
host processing, thereby making more
DMIPS available to enable high-end
functions performed concurrently with
audio/video programming and enter-
tainment.
STB04xxx and STBx5xxx controllers
include five subsystems: processor,
memory, digital audio/video, 2-D
graphics, and peripheral interface.
Third-generation single-chip devices,
STB04xxx and STBx5xxx controllers
demonstrate IBM's commitment to
satisfying emerging STB requirements
through a range of advanced features.
Design flexibility supports diverse
applications
STB04xxx and STBx5xxx controllers
can offer the flexibility to satisfy
manufacturers' individual application
requirements. STB manufacturers can
choose from controllers featuring either
a 175-DMIPS or a 350-DMIPS
embedded PowerPC 405. For
applications requiring even more

Graphics subsystem enables full 2-D
capabilities
The 2-D graphics subsystem incorpo-
rates a 2-D bitBLT engine supporting
up to 32 bits per pixel, graphic scaler,
command list controller, and display
engine to enable creation of brilliant
graphics and animation. This capability
allows service providers to offer graphi-
cally rich user interfaces for next-gen-
eration interactive applications.
The graphic scaler can perform
independent horizontal and vertical
scaling, using arbitrary scaling factors,
to provide zooming capabilities. The
command list controller executes a
command list from memory to control
the operations of the BLT engine
and graphic scaler, without processor
intervention. The display unit supports
up to five physical layers, including
background, image (still), video,
graphic, and cursor. In addition, it can
support many logical layers based on
the system memory available. The 2-D
graphics subsystem features:
Support for frame-based,enhanced
color depth
Programmable background color
behind the background layer
Multilevel blending
Graphic control output for the
external multiplexer (picture-in-
picture)
Square pixel filter for the graphic
and cursor layers
Automatic RGB/YCbCr conversion
for the graphic plane
Anti-flicker filter

two DMA controllers, providing a total
of 8 channels supporting up to 256 MB
of SDRAM; two SDRAM controllers; an
external bus interface unit (EBIU) sup-
porting up to 256 MB of RAM, ROM, or
Flash memory; an intelligent crossbar
switch (ICBS); and an external pro-
cessor interface (EPI) to a PowerPC
processor. The ICBS is designed to
