MOST(r) Technology Successfully Adopted by Asian Carmakers

80 Car Models Worldwide Now Have MOST Inside

The MOST Cooperation gladly reports the fast-growing acceptance of MOST Technology worldwide. Since the first MOST car model in 2001, 80 vehicle models have implemented the MOST infotainment backbone. Besides Europe, MOST Technology is gaining widespread popularity in Asia's automotive market. Its latest vehicle models are the Toyota Land Cruiser and the Lexus HS250h. Representing the practical application of infotainment technology in hybrid vehicles, MOST multimedia networks feature in the Toyota Crown Hybrid, Prius, and in the hybrid version of the new Lexus RX SUV and Lexus HS250h. In addition, the use of MOST Technology in the Toyota Prius shows that the multimedia network has also made inroads into the mass-produced models of the mid-range sector. The new premium sector Hyundai Equus also relies on MOST for data transmission within its all-round driver information system. The vehicles presented so far along with the Hyundai Genesis, Kia Mohave, Lexus IS, SsangYong Chairman, and the Toyota models Alphard, Crown, Estima, Mark X ZiO, and Vellfire, add up to a grand total of 14 models manufactured by Asian automakers with MOST built in.

Whereas MOST25 Technology - based on optical data transmission using optical fibers and under development for many years in Europe - has established itself in the Korean market, the Japanese market in particular prefers MOST50, the second generation of the multimedia standard. The most significant new feature of MOST50 is that it allows electrical implementations instead of using plastic optical fiber (POF). It enables data transmission over an unshielded twisted pair (UTP) of copper wires while meeting stringent automotive electromagnetic compatibility requirements.

To cope with the harsh environment in the vehicle - in particular with regard to the electromagnetic properties of the electrical physical transmission medium - numerous measures were implemented in the development of the second MOST generation. Both emitted radiation and immunity against electromagnetic interference, generated, for example, by the electric drive train of a hybrid or electric vehicle, have been optimized in a way that allows use of the technology in the demanding environment of automotive applications. The measures extend to all levels of the ISO/OSI layer model. On the level of the physical transmission medium, for instance, cost-efficient transformers for decoupling are used as a means of wiring up the network controller. The catalyst for Asian manufacturers planning to take MOST50 onboard was the option of retaining their existing wiring and assembly processes - eliminating the need to switch to fiber optics.

This year, the MOST Cooperation will once more demonstrate outstanding infotainment solutions to Asian carmakers, suppliers, and media representatives. The MOST Interconnectivity Conference Asia will celebrate its 10th jubilee in Tokyo (Japan) on November 5, 2009, presenting a summary of recent technological innovations and future trends, along with a roadmap for moving forward.

About MOST Technology

MOST (Media Oriented Systems Transport) is a multimedia networking technology optimized for use in cars and other applications. It enables the transport of high Quality of Service audio and video together with packet data and real-time control over a single transmission medium. MOST can use plastic optical fiber or electrical unshielded or shielded twisted pair wire physical layers that meet automotive environmental requirements. Today MOST is used in 80 car models as the communication backbone for their information and entertainment equipment.

About MOST Cooperation

The MOST Cooperation is the organization through which MOST Technology is standardized and refined so that it continues to stay abreast of the latest industry requirements. Today it consists of 16 international carmakers and more than 65 key component suppliers. They have joined together to work with MOST Technology and to contribute to its innovation. The MOST Cooperation is prepared to embrace efforts to further develop and standardize the technology for other industries and to establish the corresponding work structures. The MOST Cooperation was founded in 1998 to standardize MOST Technology as a global standard for multimedia networking. Audi, BMW, Daimler, Harman/Becker and SMSC are its core partners and constitute its Steering Committee. For more information see www.mostcooperation.com.
