Abstract:

With the growing number of the in-vehicle electronic devices, the weight of vehicle increases, wiring becomes more difficult, EMI (Electronic Magnetism Interfere) affects the quality of transmission.The software and hardware design of MOST-based in-vehicle audio system are introduced. Audio devices can be controlled, stream data can be transmitted, and functions related to transmission can be explored. The experiment indicates that MOST bus has the advantages of anti-interference, low quality, high speed and low cost. So it becomes foundation and theory for applying MOST to in-vehicle multimedia, smart homes, or add other in-vehicle devices to MOST bus afterwards.

Key words: media oriented system transport bus, media oriented system transport protocol, audio system
