MOST Cooperation Demonstrates Seamless Integration of Ethernet-based Devices with MOST

The MOST Cooperation (MOSTCO) – the standardization organization for the leading automotive multimedia network Media Oriented Systems Transport (MOST) – presents the seamless integration capabilities of Ethernet-based devices with MOST. „We are proud to announce that automotive Ethernet will go into series in 2012 via MOST150,“ stated Dr. Christian Thiel, MOST Cooperation Administrator. „Prepared for rollout in 2012, MOST150 provides an automotive-ready physical layer for Ethernet protocols in addition to transporting high-definition audio and video within the car. This makes MOST the ideal network backbone for a broad variety of IP-based applications such as supporting apps on connected services and Internet access in general. MOST is thus comparable to an IEEE802.x network.“ The MOST150 network supports today’s consumer standards such as UPnP (Universal Plug-n-Play) and DLNA (Digital Living Network Alliance) as well as diagnostics standards (DoIP). The flexibility of MOST network technology allows star, daisy-chain, tree, and other topologies implemented on different physical layers: POF, coax based electrical physical layer, and shielded and unshielded twisted pair (STP/UTP) copper wires.

Typical Ethernet-based applications include: an Ethernet gateway lifts Ethernet Packets from a 100BaseT Network to a MOST Network and vice versa. A web server provides web content to other participants in the MOST network. A Network Attached Storage (NAS) provides a file system to other participants in the MOST network. A UPnP server/client architecture can be directly applied to the MOST system to stream audio/video data from UPnP server to the iPad. The central MOST Hub device shows how the different physical layer and topology options may be applied according to the application requirements.

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 fibers (POF), coax based electrical physical layer, and shielded and unshielded twisted pair (STP/UTP) copper wires, that meet automotive environmental requirements. Today, MOST is used in over 110 car models as the communication backbone for their information and entertainment equipment.

About MOST Cooperation
The MOST Cooperation (MOSTCO) 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 60 key component suppliers. They have joined together to work with the 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 and SMSC are its core partners and constitute its Steering Committee. For more information see http://www.mostcooperation.com.
