MOST Bus Diagnosis
System Overview
MOST Technology
Until very recently, only very few entertainment-related control units were networked. In the
course of the development, the number of components increased continuously.
In addition, the scope of functions of individual components has been extended consider-
ably. In particular, however, completely new logical networking means that all the compo-
nents are growing to become a system: individual functions work together and produce a
high-quality overall system. This results in significant growth in system complexity.
This new dimension of system complexity can no longer be managed using the existing bus
systems.
MOST Multimedia Network
MOST technology meets 2 essential requirements:
1. The MOST bus transports control data as well as data from audio, video, navigation and
other services (SMS=Short Message Service, TMC =Traffic Message Channel, in other mar-
kets).
2. MOST technology provides a logical framework model for control of the variety and com-
plexity of data: the MOST Application Framework. The MOST Application Framework
organizes the functions of the overall system.
MOST is able to control and dynamically manage functions that are distributed in the vehi-
cle.
