Abstract:
For the last four decades, the number and sophistication of electronic systems in vehicles have shown an exponential increase. One high-growth area is telematics systems – the convergence of mobile telecommunications and information processing in cars (radios, Web browsers, CD/DVD players, telematics, and infotainment systems). There is the need for a high-speed serial interface for future vehicles, able to share audio-video sources between all passengers and able to connect automotive electronic world with consumer electronic world. Different networks are available for multimedia automotive applications. Because of their capabilities IDB-1394b and Most are strong candidate. IDB 1394 is the automotive version of IEEE 1394 version b. It is designed for high-speed multimedia applications that require large amounts of information to be moved quickly in a vehicle. Key features include hot plug capability, compatibility with consumer electronics and the ability to use small, flexible, and inexpensive cables and connectors. Its flexible topology supports both branching and daisychaining of nodes. MOST (Media Oriented Systems Transport) is a Multimedia optical fiber system transport that is designed for the automotive environment. This paper presents the main characteristics of these two multimedia protocols. It includes the electrical characteristics, topology, transmission media, software layers… It includes as well some examples of applications and platform development
