Research And Design Of Vehicle Player Based On AVB

With the rapid development of automobile industry,the on-board audio and video entertainment system is one of the most important of the automotive electronic components,its market value.This paper introduces the research and implementation of the application of on-board Ethernet AVB technology in vehicle-borne entertainment system,introduces and analyzes the transmission and communication of automobile network,and studies the overall framework of automobile network.The entertainment system on-board is established in the project of DTV of CTYAET by author.Referring to the traditional research method of the vehicle audio and video entertainment system,this research adds the current vehicle networking technology,through the addition of network communication module,the audio and video signals on the network can be transmitted to the vehicle inside the vehicle,and the left and right back headrest screen and so on.By changing the traditional audio and video transmission protocol(LVDS)into the fast developing Ethernet AVB protocol,a set of on-board player based on AVB is developed by using the traditional radio,digital TV and other functions.The main goal of this research is to complete a set of hardware vehicle,left rear headrest screen,right rear headrest screen,wire harness,and cooperate with software engineer to realize audio and video interconnection based on Ethernet AVB.Receive DTMB digital TV signal and network video in the car,left rear headrest screen,right rear headrest screen real-time synchronization and switching functions.The paper improves the correct vehicle networking technology through through addition the network module,the research of this vehicle audio and video entertainment system will be applied in the hongqi-h7 based on.
