Industry's first devices that enable rear-seat entertainment using
high-speed video image transmission
SUNNYVALE, Calif., Nov. 5 /CNW/ -- Fujitsu Microelectronics America, Inc.
(FMA) today announced the two new controller ICs -- the MB88388A and MB88389
-- that support the IDB-1394 standard for in-vehicle multimedia networks.
The MB88388A is the industry's first device to support vehicle navigation
imaging using the IDB-1394 standard. The controller implements the Fujitsu
proprietary SmartCODEC, a video codec specified under the IDB-1394
international standard for in-vehicle video transmission. SmartCODEC, which
was developed by Fujitsu Laboratories Ltd., can compress and decompress
high-resolution video without perceptible latencies in two to three
milliseconds, which is much faster than the video frame rate. By combining the
MB88388A with the MB88389 IC for IDB-1394-compliant audio, it is possible to
realize a high-quality, cost-effective, rear-seat entertainment system.
Both the MB88388A and the MB88389 ICs incorporate the physical layer
(PHY) and link layer functions specified in the IDB-1394 standard, with
support for 100/200/400 Mbps data transmission speeds. This single-chip
implementation reduces the number of parts required. Both of the new devices
also implement digital transmission content protection (DTCP) to prevent
unauthorized duplication of digital content. Two streams can be simultaneously
encrypted and decrypted.
IDB-1394 Network Expected to Move into Widespread Use
IDB-1394 is an international data networking standard for transmitting
video, audio, and other multimedia data over a vehicle network. Various
automobile manufacturers now view the standard as ideal for rear-seat
entertainment systems that can play DVDs, show digital TV programs, and offer
access to the car navigation system. Anticipating the future demand for
rear-seat entertainment systems, Fujitsu and Fujitsu VLSI Limited co-developed
the MB88388A navigation-imaging, video and audio transmission controller, and
the MB88389 audio transmission controller based on the IDB-1394 standard.
The SmartCODEC codec for video is used in the BT.601 Transport over IEEE
1394 standard, a protocol for sending BT.601 video streams such as YUV and RGB
over the IDB-1394 network. The codec enables video from DVD, digital TV, and
navigation sources to move through the network while maintaining high-quality
images at one third of the original image data size. Encoding occurs only
within the SmartCODEC's internal line memory, so external frame buffers are
Also, because IDB-1394 can be configured as a multiplexing network,
multiple video and audio streams can be transmitted simultaneously over the
same physical layer. As a result, the vehicle network can carry complex
information over a single cable, reducing wiring-harness complexity and
weight. The MB88389 controller can be integrated easily into the IDB-1394
network to reduce the cost of audio networking.
Fujitsu plans to expand its range of IDB-1394-compliant offerings to
accommodate various types of multiple data transmission from peripheral
vehicle cameras, while reducing system cost even further.
"We are pleased to see the first fully integrated IDB-1394 compliant LSI
product from Fujitsu," said Mark Spain, director of the Microsoft Automotive
Business Unit of Microsoft Corporation. "We support this standard and plan to
utilize it for the Microsoft Auto platform designed to create advanced
in-vehicle infotainment systems. As digital experiences grow, software and
services are expected to converge in the car, requiring standard platforms and
enabling technologies like those from Microsoft and Fujitsu."
Sample Pricing and Availability
The new MB88388A and MB83389 will be packaged in LQFPs and will be
available beginning in December with sample prices starting at $17 and $12.80,
