MULTIMEDIA DATA TRANSFER SYSTEM USING IN-CAR LAN
This paper discusses and verifies the feasibility of a prototype system that transfers music signals via an in-car local area network (LAN). In recent years, along with diversification of in-car electronic devices, a lot of attention has been given to in-car LAN, which reduces wiring harnesses and enables common control among electronic devices. Currently, most of the communication network for audio/visual (AV) devices is done only be "control command." In the specific case of transferring compact disk (CD) digital data by packet communication of in-car LAN, time lag will be generated by asynchronous clocks of transmitter and receiver. This time difference is the problem to be solved. In conventional transfer of CD digital data, synchronous communication is realized by separate and specific lines of data transfer and command control. In this paper, an explanation is provided on how to solve time difference of asynchronous clocks of transmitter and receiver by "connecting operation" using shock-proof memory controller. Using its memory controller, asynchronization of different clocks will be absorbed and CD digital data transfer will be realized by in-car LAN packet communication. As an example of in-car LAN using transfer method ARCNET, the prototype sample of the music transfer system between CD changer and CD controller was made. In the prototype system, music data transfer in connection between asynchronous-operating CD changer and CD controller by LAN was verified not depending on transfer rate of CD digital data.
