1 Annual Achievement Report 2013

2 MOST150 Pumps Up the Volume Succeeding the initial rollout in 2012, the third MOST generation MOST150 based on the MOST Specification Rev. 3.0 is now tremendously increasing in volume. The rollout has started in the new Audi A3 and will be followed by Daimler s S-Class vehicles. Following this, the technology will roll out successively through other car models in these two groups. Further carmakers in Europe and Asia will also use MOST150 for their upcoming car models. With the MOST Ethernet channel being used on the road to transmit IP data within the vehicle, there is no more need to force all data into a particular format to fit a single transmission protocol. MOST transports different types of data in parallel and independent data channels that provide mechanisms optimized for the specific characteristics of the data to be transported. In addition, the flexibility of MOST allows various topologies like star, daisy-chain, tree, and more implemented on different physical layers such as plastic optical fiber (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, are 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 rapidly growing acceptance of this de-facto automotive network standard by key carmakers worldwide. The number of vehicle models based on the MOST backbone already totals over 140 vehicle models on the road today will also mark the ongoing expansion into the American continent with General Motors releasing further vehicles including MOST.

6 MOST Technology Founded 15 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 knowledge 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 which 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 automotive-ready 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), Polymer Clad Silica (PCS), Shielded (STP) and Unshielded Twisted Pair (UTP) copper wires, coax based electrical physical layer, in addition for the future Glass Optical Fiber. 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 2013

8 MOST Specifications Update Whereas MOST Specification Rev. 3.0 and its collaterals are finalized and the first vehicles are on the road with MOST150 Technology, the MOST specifications are continually amended and upgraded to further enhance MOST multimedia network technology towards the carmakers needs. Currently, MOST Specification Rev. 3.1 is in preparation and investigations towards MOSTnG are ongoing. The various Working Groups have published new revisions of several specifications, e.g., the MOST Dynamic Specification, MOST Content Security Specification, and MOST Stream Transmission Specification. Considering content protection, on one hand, the DTCP Content Protection Scheme has been amended with respect to new DTCP Supplement H (DTCP with AES-128) issued by DTLA. On the other hand, the content protection scheme HDCP has been investigated and the HDCP Content Protection Scheme Specification has been prepared. Beyond that, additional Function Blocks have been overhauled with the help of the revised MOST Database Editor, e.g. AuxIn, Diagnosis, DVD Video Player and TV Tuner Function Blocks, and their corresponding xml exchange format which defines the API (Application Programming Interface). Working Groups Working Groups One of the routine tasks is the optimization of the Compliance Testing Process and the Compliance Test specifications. The mandatory Core Compliance Tests have been extended with Electrical Control Line and MOST High Protocol test cases. Further development, e.g. a cable model, has been done regarding MOST150 on a coax-based electrical physical layer, which meets the requirements not only for the traditional areas of entertainment and information, but also for driver assistance. With the option of different topologies and the combination of different physical layers, one of the up and coming features is providing the power supply on the same cable.

9 MOST Achievements 8 // 9 MOST150 Has Hit the Road in the New Audi A3 The MOST Cooperation welcomes the recent rollout of the new Audi A3, the first car model that integrates the latest MOST Generation MOST150. Since first implementing MOST in an Audi car in 2002, MOST has become the established standard for the networking of premium infotainment systems at Audi. Now the new generation MOST150 is being launched in the new Audi A3 series. Following the Audi A3, the technology will roll out successively through each series in the Volkswagen group. In-car Ethernet Released into Series Production With the current MOST150 rollout, the MOST Cooperation has added the dedicated Ethernet channel to the other widely used transport mechanisms already supported by MOST for the transmission of audio, video and control information. The Ethernet Channel of MOST150 runs like an IEEE802.x network. MOST150 adds Ethernet technology to a networking technology that was designed to meet stringent automotive requirements. MOST provides the ideal network backbone for a broad variety of IP-based applications such as supporting apps on connected services and Internet access in general. The MOST Ethernet Channel provides the necessary infrastructure to implement all necessary protocols and mechanisms required to support Internet access in a distributed infotainment system, such as the Internet Protocol (IP), the Transmission Control Protocol (TCP), or the Hypertext Transfer Protocol (HTTP). Simultaneously, MOST maintains other essential communication features, such as synchronous and isochronous channels for easy and efficient audio and video streaming. The MOST150 network provides an efficient and easy to use solution for transmitting IP traffic. Investigations on the throughput with the maximum bandwidth allocated for the packet channel proved that a net bandwidth of over 107 Mbit/s can be achieved, showing that the maximum bandwidth of Mbit/s can be utilized with efficiency of over 75 percent. Application Note for MOST150 Coaxial Standard An application note has been made available that describes a test board for the MOST150 Coax Physical Standard that uses a cable model based on available discrete components. Set up by the Working Group Physical Layer according to the compliance measurement guideline, this application note is available for MOSTCO members to be used for compliance checking. The application note refers to the released MOST150 Electrical Physical Layer Sub-Specification Rev. 1.0 based on coaxial cable. This MOST150 coax physical standard complements the existing MOST150 optical physical layer in the infotainment domain, especially for OEMs who have strong preferences for an electrical physical layer. In addition, this new standard opens the way for using MOST in other vehicle domains. For example, it fits well in the driver assistance domain, as this physical layer is able to provide bi-directional communication and power supply on a single coaxial cable.

10 MOST Events Worldwide 13th MOST Interconnectivity Conference Asia The MOST Cooperation hosted the 13th MOST Interconnectivity Conference Asia on November 15, 2012 in Seoul, South Korea. Representatives of the MOST Cooperation presented an update on the latest technology achievements and the MOST standardization roadmap to up to 100 attendees of Asian carmakers and their suppliers. In the accompanying exhibition, the MOST Cooperation presented the network integration of diverse applications such as Advanced Driver Assist Systems (ADAS) and easier connection to IT systems inside and outside the vehicle. In addition to the MOST Cooperation, further demonstrations were shown by member companies. International VDI Congress Electronic Systems for Vehicles At SAE Convergence on October 16 to 17, 2012, the MOST Cooperation exhibited the latest technology highlights at Booth 706. During this leading automotive exhibition in Detroit (Michigan, United States) at the Cobo Center, the MOST Cooperation also celebrated the expansion of MOST Technology to the United States. The MOST Cooperation welcomes the newest vehicles from General Motors to the MOST family. The first cars on the road are the all-new Cadillac XTS luxury sedan, the Cadillac ATS and the Cadillac SRX, which will be followed by other GM car models. MOST Forum The fourth MOST Forum on March 20, 2012 in Stuttgart/Esslingen (Germany) celebrated a significant milestone of MOST Technology: with MOST150, the third MOST generation has gone into series in Thus, for the first time, the MOST Ethernet channel is being used in practice to transmit IP data within the vehicle. MOST150 provides an automotive-ready physical layer for Ethernet protocols in addition to transporting high Quality of Service (QoS) audio and video within the car. The recent MOST Forum provided exciting presentations about the latest developments and research results. Several carmakers and suppliers gave insight into automotive IP-based data transmission and presented an outlook on future network technology and applications connected over MOST, such as driver assist systems, mobile devices, and Internet access.

11 MOST Achievements 10 // 11 MOST Roadmap The first and second generations of MOST are now on the road around the world in over 140 vehicle models from many car manufacturers, and the third generation has started series production as well. The first generation, MOST25, operates at 25 Mbit/s. 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 Mbit/s. 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, and recently another US carmaker has launched MOST50 based vehicles. MOST150 is the third generation, offering a bandwidth of 150 Mbit/s. 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 manufacturers to adjust the bandwidth of a conventional streaming connection on the one hand and IP communication on the other according to the corresponding requirements. In addition, MOST150 still supports the well-known asynchronous channel to ensure backward compatibility with 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. The next steps in the MOST roadmap are the connectivity requirements and considering the costs of the next generation infotainment. Emerging applications and trends in the infotainment domain are: Seamless HD audio/video integration with content protection Integration of portable consumer devices Freely programmable instrument clusters Rear seat entertainment systems Concurrent control MOST Cooperation will provide appropriate specification modules for these kinds of applications. There will be a need to define new gateways, for example, for car-to-car and car-toinfrastructure and WLAN hotspot access. As a mainstream technology, IP communication will play a major role, bridging to heterogeneous networks, audio and video on demand; connected services as well as seamless integration of consumer stacks will be reflected in standardization. Applicability to other vehicle domains such as driver assistance is another important aspect, especially in the case that these domains are growing together with infotainment. As a consequence, the next generation network must allow for compressed and uncompressed video transmission, increased functional safety requirements, transmission of other sensor data, and support of additional topologies and physical layers. Next generation MOST will enhance the bandwidth up to 5 Gbit/s. This will lead to improvements and innovations in the physical layer, in both FOT concepts and optical connections. The 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 and Extended diagnostic capabilities MOST Annual Achievement Report 2013
