Fujitsu and XSYS Develop MPEG-2 Encoder System For Prototype In-Car Digital Video System

Feb 06, 2001, 00:00 ET from Fujitsu Microelectronics Europe

    LONDON, Feb. 6 /PRNewswire/ -- Fujitsu Microelectronics Europe has
 announced that it is working closely with XSYS Interactive Research of
 Villingen, Germany, on the implementation of Fujitsu's MPEG-2 encoder in a
 sophisticated in-car digital video and data distribution system.
     Unlike previous-generation analogue systems which were based on copper
 coaxial cabling, the highly advanced video and data processing developed by
 XSYS for this application allows the transmission via a digital bus based on
 plastic optical fibre.
     The Fujitsu MB86390 MPEG-2 encoder is one of the industry's first
 single-chip solutions for MPEG-2 encoding, including all three key functional
 elements; video, audio and system multiplexing, in a single IC.  An embedded
 Fujitsu SPARClite CPU controls the complete encoding and multiplexing process.
 Implementation within a single-chip enables costs to be minimised, allowing
 the device to meet the particularly cost-sensitive demands of in-car systems.
     The MPEG-2 encoder has been proven by XSYS to have exceptionally stable
 performance in the demanding environmental conditions prevalent within the
 car, being especially robust against analogue 'noise' to which MPEG image
 compression techniques are normally susceptible.  The reason for that is the
 using of smart and sophisticated coding algorithms.
     A typical in-car video distribution system, using the MB86390, would
 consist of TV tuner, MPEG-2 encoder and LCD displays with built-in MPEG
 decoders.
     In order to achieve the typical 320 pixels by 240 lines resolution of LCD
 displays in such a system with a progressive frame format, it has been shown
 that a bit-rate of approximately 5Mbit/sec is sufficient, even with noisy TV
 signals.
     In less noisy applications, such as those with in-car cameras as the
 signal source, the bit rate can be reduced to about 1.5Mbit/sec.
 
     XSYS is a leading German design house specialising in advanced systems for
 automotive entertainment and communication, including car radios, CD players
 and navigation systems.  A subsidiary company of Harman/Becker, XSYS creates
 new designs and builds finished prototypes, which are transferred to its
 parent group for volume production.
     Fujitsu Microelectronics Europe is a major supplier of semiconductor
 products to the European and global market. The company's main business focus
 is on providing systems solutions to the networking/telecommunications, mobile
 communications, automotive and multimedia markets. This integrated solutions
 approach is supported by a broad range of semiconductor devices, including ATM
 telecommunications ICs, RF devices, PLLs and SAW filters, microcontrollers and
 microprocessors, FCRAMs and Flash memory.  The company is also a leader in
 colour plasma display panels.
