Fujitsu Launches World's First 1394 Automotive IC for HD Video
- Contributes to reduced costs, lighter wiring harness, and higher fuel efficiency -
Tokyo, April, 22, 2009 - Fujitsu Microelectronics Limited announced today the launch of the
world's first "1394 Automotive"(IDB-1394)(1) controller IC that realizes high-definition (HD) (1,280
dots x 720 lines) video transmission over the IDB-1394 in-vehicle multimedia network protocol.
The new IC, the MB88395, can simultaneously transmit multiple streams within the vehicle, such
as HD video from Blu-ray DVDs, digital TV, audio and car navigation images. The new IC realizes
this by utilizing a high-speed 800Mbps physical layer (2) as well as Fujitsu's proprietary
SmartCODEC that provides high compression and which can transmit HD video without
perceptible lag. This not only brings the rich HD experience to rear-seat entertainment, but
reduces the system cost of in-vehicle multimedia networks by a maximum of 30%, while reducing
the number of wire harnesses (cables) by a maximum of 70% to reduce vehicle weight and
improve fuel efficiency. Sample shipment of the new MB88395 will begin from April 22, 2009.
Fujitsu Microelectronics will present and demonstrate the new controller IC at the 1394
Automotive Tech seminar to be held in Detroit, US on April 30, 2009.

There is increasing attention being paid to 1394 Automotive for in-vehicle multimedia networking,
and it is expected to become common in the automotive market. The reason for this includes the
gradual shift to digital TV in each country, the increased availability of HD content, as well as the
analog output from Blu-ray players to be stopped from 2013, making 1394 Automotive necessary
for the upcoming flood of digital transmissions through in-car networks. Anticipating the future
needs for rear-seat entertainment systems, Fujitsu Microelectronics lead other vendors in
introducing 1394 Automotive controllers in 2005, and with this new 1394 controller co-developed
with Fujitsu VLSI Limited, allows more HD video content to be easily and flexibility viewed
throughout the vehicle.
This was emphasized by Yuji Kawaguchi, Operating Officer of Honda R&D Co., Ltd. in saying,
"Honda R&D welcomes the MB88395, the first IC to provide the 800Mbps speeds of the 1394
Automotive spec. The importance of high-speed digital transmissions will increase further in the
future to handle in-vehicle multimedia as well as to reduce weight. 1394 Automotive is an
in-vehicle network that can enrich entertainment and comfort. We plan to promptly evaluate the

800Mbps specification of 1394 Automotive - double the 400Mbps of the previous product - as
well the a version of the SmartCODEC compression codec for video that has an even higher
compression ratio, compressing video to one-fourth (1/4) its original size, compared to one-third
(1/3) that of the previous product. The SmartCODEC, which was developed by Fujitsu
Laboratories and is used in the BT.601 Transport Over IEEE-1394(3) standard, can compress and
decompress high resolution video in 2 to 3 milliseconds (2-3ms) without any perceptible
annoying time lag or out of sync contents, which can be a problem when watching the same
contents on the front and rear monitors.
This results in the ability to transmit HD video from Blu-ray DVDs and digital TV, as well as
high-resolution navigation images, within the vehicle without any perceptible time lag, making
this the first IC in the world to allow multiple streams of HD video and navigation images over
1394 Automotive. For example, a HD video stream (1,280 dots x 720 lines) from a Blu-ray DVD
that has been decompressed has a rate of 885Mbps. With subsequent compression to one-fourth
(1/4) with SmartCODEC, the rate becomes 249Mbps, so two (2) channels can be transmitted in
the 800Mbps bandwidth that was not possible over 400Mbps products.
Going forward, Fujitsu Microelectronics plans to expand its lineup of 1394 Automotive ICs to
handle the increasing information streams in automobiles, such as video content and peripheral
cameras on the vehicle, as well as to drive further reductions in system costs. These in-vehicle
networking chips complement Fujitsu Microelectronics' strong presence in automotive ICs for
processing graphics and video.

Key Features of the New Series
1. I Reduces system costs for rear-seat entertainment
The MB88395 IC includes the 1394 Automotive physical layer and link layer(4) as well as
DTCP digital rights management(5) on one chip, while encoding occurs only within
SmartCODEC's internal line memory, making an external frame buffer unnecessary, and
thus reducing the necessary system components and total multimedia network system
costs by a maximum of 30%. Also, by being able to simultaneously transmit at high speed
several video and audio streams as well as control signals on one network line - not
peer-to-peer - it reduces the number of the wire-harnesses (cables) by a maximum of
70%. This contributes to reducing vehicle weight, leading to higher fuel efficiency.
Concretely, this can produce a reduction in the environmental impact by approximately
10kg of CO 2 per year for a car traveling 10,000km (that translates into roughly the
amount of CO 2 a beech tree absorbs in 1 year).
2. HD video compression, decompression and transmission without perceptible time
Includes Fujitsu's proprietary SmartCODEC which can compress video data to one-fourth
in size, an improvement compared to the one-third of the previous product, and compress
and decompress video within 2-3 milliseconds. Such low latency, combined with the
doubling of the speed of the physical layer to 800Mbps, allows transmission of HD video
from Blu-ray DVDs and digital TV, within the vehicle without any perceptible time lag,
which can be a problem when watching the same contents on the front and rear monitors.
With an MPEG CODEC, there would be a perceptible time lag in transmission.
