Abstract Among the variety of vehicle technology trend issues, the biggest one is focus on automotive network system. Especially, optical network system is preferred. The aim in optical network system including vehicular environment information is that realization of media streaming service beyond the current car audio system. This paper is introduced the implementation of media streaming service which is consist of optical network as called MOST (Media Oriented System Transport) and realization of car audio system adapted to vehicular environment information collected from (On-Board Diagnosis) OBD via (Controller Area Network) CAN. Keywords In-vehicle network systems systems Media streaming service

1 Introduction With the passage of time, vehicle technology in modern times has been developed rapidly. Recent of today’s automobile research area has been gradually changed from mechanics to electronics to the way of offering entertainment service to customs that can serve the connection to smart device easily and conveniently.

In particular, most of people want to be experienced in high quality audio streaming service while they drive. According to customer’s demands, MOST system is developed to provide an efficient and cost effective fabric to transmit audio data between any devices attached to the harsh environment of automobile. Compared to conventional car audio system which has been used in many of audio electrical line, bundle of lines per an audio channel, dissimilarly being with the one optical line in order to transit the audio data source, the advanced streaming service adopted optical network system makes light harness system. As the simply network construction, it can be obtained the high fuel efficiency from the usage of plastic optical fiber and for optical signal characteristics, it makes be free on electro-magnetic problems. Considered on driving environment, car audio system as the streaming service gathering automobile information via CAN enables to tune the volume automatically for their vehicular conditions. To develop the selfcontained audio system, the complex information having vehicular status is needed to be accessed more comfortable. In Sect. 2, MOST network system and MOST data processing are introduced for vehicle environment scenario. The vehicle information processing module which classified into vehicular status information to be collected from CAN network is described in Sect. 3. In Sect. 4, plat
