MPEG-2 Decoder for Set-Top-Boxes
INTRODUCTION:
FEATURES
The SmartMPEGTM is an integrated set-top-box
decoder. As a major component of a digital video
broadcast (DVB) set-top-box or IDTV this device
uses Fujitsu’s industry-leading Cx81 CMOS
technology (0.18µm).
It incorporates an ARC Tangent A4 RISC core
(@130MHz), two transport stream demultiplexers
with integrated DVB descramblers, a PAL/NTSC
digital video encoder and a display controller, which
overlays up to four layers of OSD. This set-top-box
decoder consists of a shared memory interface for
CPU and for MPEG decoding. The universal
processor interface allows connection to FLASH,
hard disk drives and other asynchronous devices.
The minimum SDRAM required is one 64Mbit
device using 16bit data bus.

The SmartMPEGTM is the 3rd generation of
Fujitsu’s MPEG decoder, the successor to the
MB87L2250. With the MB87L2250, Fujitsu offered a
set-top-box chip, which enabled very low end
product cost. Its successor, the SmartMPEGTM
incorporates all the features which are required for
standard set-top-boxes. This high level of
integration makes it ideally suited for todays
interactive set-top-box applications.
Furthermore the Fujitsu Application Programming
Interface (FAPI) ensures a short time-to-market by
making the software development easier. The FAPI
is the programming interface for Fujitsu DVB
components as well as easing migration to future
devices.
