2 MOST150 Rolls Off the Line This year, the MOST Cooperation is celebrating a significant milestone of MOST Technology: with MOST150, the third MOST generation is going into series. Thus, for the first time, the MOST Ethernet channel is used in practice to transmit IP data within the vehicle. MOST150 provides an automotive-ready physical layer for Ethernet protocols while transporting high Quality of Service (QoS) audio and video over a single transmission medium. The flexibility of MOST allows various topologies implemented on different physical layers such as plastic optical fibers (POF), coax based electrical physical layer, and shielded and unshielded twisted pair (STP/ UTP) copper wires. We are proud that our core partner members Audi and Daimler will be the first carmakers to integrate MOST150 into series production vehicles following the new revision of the MOST Specifications. This reflects MOSTCO s path of success, with fastgrowing acceptance of this de-facto automotive network standard by key carmakers worldwide. The number of vehicle models relying on the MOST infotainment backbone already totals over 115 vehicle models on the road today will in addition mark the expansion to the American continent with the first US carmaker releasing vehicles including MOST.

6 Information mobile connectivity Entertainment connected services Driver assist MOST Technology Founded fourteen years ago, the MOST Cooperation is the organization through which MOST Technology is standardized and refined. So far, more than 300 engineers from over 100 companies have contributed their know-how for a robust and reliable network. Media Oriented Systems Transport is a multimedia network of 25, 50 and 150 Mbps bandwidth optimized for multimedia and infotainment applications. It is a network originally developed by the automotive industry for the automotive industry. MOST is a synchronous network. A timing master supplies the clock with a synchronous and continuous data signal and all other devices synchronize their operation to this base signal. This technology eliminates the need for buffering and sample rate conversion so that very simple and inexpensive devices can be connected and the hardware of the network interface itself is lean and cost effective. The technology is similar to what the public switched telephone network uses. Within the synchronous base data signal, multiple streaming data channels, asynchronous channels, and a control channel are transported. The control channel is used to set up what streaming data channels the sender and receiver are to use. Once the connection is established, data can flow continuously and no further addressing or processing of packet label information is required. The bandwidth of the streaming data channels is always available and reserved for the dedicated stream so there are no interruptions, collisions, or slow-downs in the transport of the data stream. This is the optimum mechanism for delivering streaming data (information that flows continuously) like audio and video. MOST meets the requirements not only for the traditional areas of entertainment and information, but also for the new domains of mobile connectivity, connected services, and driver assistance. In addition to transporting high Quality of Service (QoS) audio and video, it also provides an automotiveready physical layer for Ethernet protocols within the car. MOST is thus equivalent to an IEEE802.x network. The flexibility of MOST network technology allows star, daisy-chain, tree, and other topologies implemented on different physical layers: Plastic Optical Fiber (POF/LED), Glass Optical Fiber (PCS), Shielded Twisted Pair (STP) and Unshielded Twisted Pair (UTP) copper wires, and coax based electrical physical layer. MOST not only defines the physical interconnection between devices but also specifies and standardizes a lean embedded communication protocol and software framework that simplifies the development of complete systems and applications to distribute and manage multimedia content.

7 MOST Status 6 // 7 MOST Compliance Compliance to the specifications is one major element for the success of MOST Technology: The MOST Cooperation implemented an integrated compliance verification process to enhance quality while simultaneously reducing cost. The MOST compliance process covers three aspects: legal requirements, interoperability and quality. To cover legal requirements the Cooperation defines a license to use member IP such as patents and the MOST logo. In order to support functionality the compliance process assures a basic level of interoperability. MOST is synonymous with high quality and as such network implementation and its components have to be MOST compliant. Through the MOST compliance process the system integrator gets pre-tested devices and components. This inherently reduces complexity of the integration effort and increases quality substantially. The Compliance Tests are effected by MOST Compliance Test Houses (MCTHs) approved by the MOST Cooperation. They are accredited according to ISO standard General Requirements for the Competence of Testing and Calibration Laboratories by the German Accreditation Body (Deutsche Akkreditierungsstelle, DAkkS GmbH, Frankfurt, Germany). MOST Application Recommendations For further optimization, the MOST compliance testing process has been enhanced. The compliance test specifications have been extended to complete the documentation. Compliance testing in parallel to the development process has proven to be best practice. With over 75 companies contributing to MOST Technology with hundreds of solutions and products it is indispensable to assure compliance to the MOST specifications. Compliance itself mainly addresses conformity to the specification and represents the compulsory parts. In order to assure high quality, robustness and interoperability, additional recommendations called Application Recommendations have been elaborated by the OEMs Audi, BMW and Daimler with the help of some MOST Compliance Test Houses (MCTHs). In order to give an estimate for the distance from hard no-go constraints, a quality index is introduced, providing a statistical value for the assessment of a device under test. The Application Recommendations consist of several parts organized in subdocuments considering both physical layer and for core compliance aspects. These Application Recommendation documents are hosted by MOST Cooperation and thus enable the MOST Compliance Test Houses to offer additional services. MOST Annual Achievement Report 2012

9 MOST Achievements 8 // 9 Automotive Ethernet Put into Practice by MOST150 The MOST Cooperation is proud to announce that automotive Ethernet is going into series in 2012 via MOST150. 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 equivalent 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 Sample Implementation MOSTCO demonstrated at exhibitions: Seamless integration capabilities of Ethernet based devices with MOST (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.

11 MOST Achievements 10 // 11 MOST Roadmap The first and second generations of MOST are now on the road around the world in over 115 vehicle models from many car manufacturers with the third generation starting series production. The first generation MOST25 operates at 25 Mbps. A detailed Data Link Layer specification for MOST25 has already been made available by SMSC and HARMAN and can be requested by members of the MOST Cooperation. With the MOST Specification Rev. 2.5 for MOST50 the second generation the MOST Cooperation doubles the bandwidth for automotive infotainment solutions from 25 to 50 Mbps. The MOST Specification of Electrical Physical Layer Rev. 1.1 is an additional key specification that enables data transmission over a shielded or even an unshielded twisted pair (UTP) of copper wires while meeting the stringent automotive electromagnetic compatibility requirements. One carmaker in Asia has vehicles on the road that are based on this specification. Other carmakers will launch respective vehicles soon. MOST150 is the third generation offering a bandwidth of 150 Mbps. With the transmission over legacy POF/LED optical physical layer MOST150 offers a smooth migration from MOST25 and MOST50 allowing carmakers to continue to use POF and LEDs as light sources. In addition to higher bandwidth MOST150 features an isochronous transport mechanism to support extensive video applications, as well as an Ethernet channel for efficient transport of IP-based packet data. This channel carries legacy Ethernet packets (according to IEEE 802.3) so standard TCP/IP stacks can be used without change. Thus, the new generation of MOST provides the automotive-ready physical layer for Ethernet in the car. This way, MOST will be open to a broad variety of IP based applications. It even allows to adjust the bandwidth of conventional streaming connection on the one hand and the IP communication on the other according to the corresponding requirements. Besides, MOST150 still supports the wellknown asynchronous channel to ensure backward compatibility of MOST25 applications. With MOST150, audio and video signals can be transported with high bandwidth efficiency and without any overhead for addressing, collision detection/recovery or broadcast. Multiple high definition (HD) video streams and multi-channel surround sound with premium quality of service can be transmitted, while simultaneously moving high loads of packet data around. Next steps in the MOST roadmap comprise the next generation infotainment connectivity requirements and considering cost-down effects. Emerging applications in the infotainment domain are: Seamless integration of portable consumer electronic devices Support of HD audio and video content, e.g. Blu-ray or HDTV Camera applications Rear seat entertainment systems Gateways (Ethernet SW download and diagnosis ) IP communication between applications Enhanced diagnostics capabilities Driver assistance systems Future generation MOST will enhance the bandwidth in the range of several Gbps. MOST network needs to support digital audio, video and data services equally: High QoS Synchronous (PCM audio ) High QoS Isochronous (MPEG Transport Streams, audio and video over IP ) High performance Packet with IP support Real-time Control Improved Connector Concepts: Improvements and innovations in the physical layer, e.g. optical connections MOST Annual Achievement Report 2012
