摘　　要：为了适应机动灵活、快速反应的要求,视音频系统建设已从地面固定模式向机动模式快速发展。考虑到车内实际安装环境,上车设备要求集成度高、体积小,同时对外接口尽量统一,方便车内布线,传统的固定场所内的视音频设备很难满足使用要求,这就需要研制一种新的车载式视音频装置。提出了一种车载视音频综合处理装置的设计方案,该装置按3U VPX标准尺寸进行模块化设计,集成了视音频编解码、视频会议、视频矩阵等功能,并可进行功能扩展。In order to meet the requirements of flexible and quick response,the construction of video and audio system has been developing rapidly from fixed mode to mobile mode.Considering the actual installation environment in the car,the equipment on board required high integration,small size,as well as unified external interface to facilitate cabling in the car.It was difficult for the traditional audio-visual equipment in fixed places to meet the use requirements,which required the development of a new vehicle-mounted audio-visual device.It was presented that a design scheme of vehicle audio-visual integrated processing device,the device was modularized according to 3 U VPX standard size.It integrated network coding and decoding,video conferencing,video matrix and other functions,and can be extended.
