The latest developments towards a high-speed data bus standard will be introduced by 2005 in novel vehicle designs for numerous high-speed, real time multimedia applications. These applications will provide the car owner access to information, entertainment, communication, and safety as well as the Internet, driving the need to have a high-speed data bus serving as backbone for data traffic between different applications. Currently, the minimum bus speed being considered for such applications is 100 MBPS, which is suitable for transmitting a compressed video and audio data stream. Concerns about electromagnetic interference (EMI) and weight have driven the physical media requirement to be plastic optical fibre (POF). World-wide working groups and consortia have been aiming at developing one high-speed data bus standard to be used across the automotive industry. The ERTICO group has consolidated the list of potential standards down to five. Two relatively new groups have surfaced over the past year: the AMIC (Automotive Multimedia Interface Collaboration) group is made up of 96% of the world-wide car manufacturers, the IDB (Intelligent Data Bus) Forum is made up of over 60 companies including vehicle manufacturers, bus developers, the consumer electronics industry and IC developers. They will further ERTICO's efforts and will choose one bus standard. As of June, there are two standards, MOST and 1394b (Firewire), being under review by AMIC and the IDB Forum as potential automotive multimedia bus candidates. The focus of this paper will be describing the key features and major limitations of each of the two bus standards.
