Description
The IBM39MPEGCS24PFA16C and
IBM39MPEGCS24DPFA16C are high performance
audio/video decoders, designed for high-end decom-
pression applications, such as broadcast distribution,
professional audio/video editing and content creation,
digital television set-top boxes, and high-end PC multi-
media applications. They comply with the ISO/IEC
13818-2 Recommendation H.262 Draft International
Standard (MPEG-2 standard) Main Profile @ Main
Level and 4:2:2 Profile @ Main Level. They support
interlaced output video data and are capable of sup-
porting MPEG-2 I,P,B compressed data streams up to
a sustained rate of 50 Mbps.
These decoders provide an MPEG transport demulti-
plexer, an MPEG video decoder and two MPEG/Dolby
Digital audio decoders. The transport demultiplexer can
receive transport streams up to 160 Mbps. The video
decoder can decode MPEG-2 Main Profile as well as
4:2:2 Profile @ Main Level video packetized elemen-
tary streams. Dual audio decoders can decode MPEG
Layers I and II and Dolby Digital
(IBM39MPEGCS24DPFA16C only) packetized ele-
mentary streams. Two built-in PLLs generate the audio
sampling frequencies and support audio and video
synchronization. Gen-lock is supported by providing
separate video and STC clock inputs. The
IBM39MPEGCS24PFA16C and
IBM39MPEGCS24DPFA16C are 208 pin, plastic quad
flat pack (PQFP) package devices.
The integrated audio decoder is capable of decoding
Dolby Digital 5.1 channels, or MPEG-2 compatible
Layer I and II streams in support of compliant bit rates
and sample rates to produce two-channel basic stereo
(with no downmixing) digital audio output.
