Video Compression from MPEG-2 to H.264 Extends Recording Time by a Factor
of 2.5 for High-Volume Consumer Applications
SUNNYVALE, Calif., Aug. 28 /CNW/ -- Fujitsu Microelectronics America,
Inc. (FMA) today extended its family of high-performance H.264-compliant ICs,
announcing a new transcoder designed to compress full high definition (1920 x
1080) MPEG-2 video data to H.264 data for high-volume consumer applications.
The new Fujitsu MB86H52 can compress MPEG-2 video data to less than half
its original size, enabling transmission of full HD video over narrow
bandwidths while maintaining high video quality. The combination of
capabilities makes the MB86H52 ideal for high-volume consumer products,
including hard disk recorders (where recording time can be lengthened by more
than 2.5 times), video recorders (PVRs) and set-top boxes (where the
compression technologies reduce video data sizes significantly, creating
longer recording times).
The transcoder operates at an internal frequency of 216MHz, and
incorporates DDR2 memory, with a 324MHz interface. Power requirements are 2W,
with 1.2V typical during HD transcoding.
The functionality of the new transcoder is based on video processing
technology developed for the MB86H51, an H.264 CODEC introduced by Fujitsu in
May 2007 (see related press release at
http://www.fujitsu.com/us/news/pr/fma_20070523.html). The MB86H52 incorporates
the full HD H.264 CODEC used in the MB86H51 for video encoding and decoding.
As with all the members of the product family, the MB86H52 uses proprietary
video compression algorithms developed by Fujitsu Laboratories to reduce the
processing burden while producing superior image quality. Fujitsu's system
memory technologies enable a compact system with low power consumption.
H.264 is the most recent international standard for video compression,
jointly defined by the ITU-T (International Telecommunication Union,
Telecommunication Standardization Sector) and ISO/IEC (International
Organization for Standardization/International Electrotechnical Commission).
"The MB86H52 delivers an H.264 compression ratio that is 2.5 times the
ratio of MPEG-2, providing customers with significant savings in total hard
disk space," said Davy Yoshida, director of business development, Fujitsu
Microelectronics America. "For bandwidth-limited applications that require
transmission of high-definition video streams, the benefits of compressing
from MPEG-2 to H.264 are compelling. The new MB86H52 transcoder is ideal for
Pricing and Availability
The new MB86H52 transcoder will be available in September. It is packaged
in a 496-pin PBGA, and sample pricing will start at $250 each.
