Single-chip decoders for professional customers
MPEGCS24 Digital Audio/Video Decoders
Highlights
Enabling c ost-effec tive,
value-add produc ts
The IBM
MPEG-2 digital audio/video
decoders, IBM MPEGCS24 and IBM
MPEGCS24D, are advanced, high-
performance chips designed to satisfy
the needs of customers developing
professional audio/video products. New
members of IBM’s family of MPEG-2
products, these single-chip decoders
are suited for professional audio/video
editing, broadcast, and a range of
emerging applications.
IBM MPEGCS24 and IBM MPEGCS24D
decoders can decode MPEG-2 4:2:2
Profile at Main Level video, Main Profile
at Main Level (MP @ ML) video, and
MPEG-2 stereo Layer I & II (CD quality)
audio. The IBM MPEGCS24D decoder
offers the added ability to decode
Dolby
Digital audio.* Both decoders
feature an
integrated transport stream
demultiplexer
and SDRAM interface.
The MPEGCD21 was IBM’s initial 4:2:2
profile decoder offering. Today the IBM
MPEGCS24 and MPEGCS24D decoders
build on this successful technology to
give customers a combination of
capabilities for designing value-add
products quickly and affordably.
A flexible, single-chip solution
for high-performance systems
IBM MPEGCS24 and IBM MPEGCS24D
decoders feature 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
expense.
Integrated transport stream
demultiplexer
The integrated transport stream
demultiplexer accepts continuous input
at a rate of up to 160 Mb/s in parallel
format or 60 Mb/s in serial format.
Compliant with the ISO/IEC 13818-1
system layer standard, it incorporates a
range of capabilities, including data error
detection, reporting and concealment,
programmable PID and table filtering,
and flexible packet data routing. These
features assist in the design of very
high-performance, complex systems
using fewer external components.
IBM’s single-chip digital audio/video decoders integrate advanced features for high-
performance solutions.
