Abstract:

The car multimedia systems generally use a traditional connection with the transmission, there is no uniform standard wiring harness and it is difficult to expand. In the study of MOST (Media Oriented Systems Transport) for multimedia transport protocol, based on the combination of MOST NetServices using ATmega128 provides the basic functions of the design and implementation of the MOST fiber-optic network DVD (Digital Versatile Disc) playback node hardware and software, and connect to the MOST fiber optic network, to achieve with the audio node, master node to control the transmission of information and multimedia information. The experimental test, based on the MOST network, multimedia messaging, voice received smooth, clear sound, no noise, smooth video playback.

Key words: media oriented systems transport（MOST）, netservices, multimedia
