Single-chip decoders for professional customers
CS24 Digital Audio/Video Decoders
Enabling cost-effective,
value-added products
The IBM MPEG-2 digital audio/video
decoders, CS24, CS24E, CS24D,
and CS24DE, are advanced, high-
performance chips designed to satisfy
the needs of customers developing
professional audio/video products.
These single-chip decoders are
intended for professional audio/video
editing, broadcast, and a range of

performance solutions.
A 鏗俥xible, single-chip solution for
high-performance systems
IBM鈥檚 family of CS24 decoders
features an integrated transport
stream demultiplexer, MPEG-2 video
decoder, dual audio decoders, and
an SDRAM interface. By integrating
these features on a single chip, the
decoders enable more complex
designs while helping to reduce
design time and effort.
Integrated transport
emerging applications.
The IBM family of CS24 decoders
can decode MPEG-2 4:2:2 Pro鏗乴e at
Main Level video, Main Pro鏗乴e at Main
Level (MP @ ML) video, and MPEG-2
stereo Layers I & II (CD-quality) audio.
The CS24D and CS24DE also offer
the ability to decode Dolby
廬
Digital
audio. The new members of the
*
CS24 decoder family, the CS24E
and CS24DE, provide all of the features
of their counterparts (the CS24 and
CS24D, respectively) with enhance-
ments such as encoded Dolby Digital
pass-through. Together, these four
CS24 decoders give our customers a
broad selection of functionality for
designing value-added products
quickly and affordably.
stream demultiplexer
The integrated transport stream
demultiplexer accepts continuous
input at a rate of up to 160 Mb/sec in
parallel format or 60 Mb/sec in serial
format. Compliant with the ISO/IEC
13818-1 system layer standard, it
incorporates a range of capabilities.
These include data error reporting
and concealment, programmable
PID and table 鏗乴tering, and 鏗俥xible
packet-data routing. These features
assist in the design of very-high-
performance, complex systems
using fewer external components.
