摘　　要：针对车辆应用中多种视频格式解码的需求,为降低其对显示终端解码能力的要求,以光纤通道视频组播技术为基础,提出一种基于嵌入式Soc处理器解码和光纤通道视频发送的视频解码系统方案,对基于嵌入式Soc的视频解码模块的设计方案进行了阐述,重点介绍了视频编解码模块的软件设计思路和流程,通过工程化搭建了一个视频解码模块和三台显示终端的车载应用验证环境,对上述方案进行了H.265标准视频解码和时延测试验证,测试结果显示,所提方案可实现单个视频解码模块支持多台显示终端同时查看视频解码图像,系统解码总延时约172 ms,表明该方案可降低对显示终端视频本地解码能力的要求。In response to the demand for video decoding in various formats in vehicle applications,a video decoding system scheme based on embedded Soc processor decoding and fiber channel video transmission is proposed.Based on fiber channel video multicast technology,the design scheme of the video decoding module based on embedded Soc elaborates the software design ideas and processes of the video encoding and decoding module.Through engineering implementation,a vehicle application verification environment was built for one video decoding module and three display terminals.The above scheme was verified through H.265 standard decoding and delay testing.Test results showed that the proposed scheme can achieve a single video decoding module supporting multiple display terminals to view video decoded images simultaneously,with a total decoding delay of about 172 ms.This indicates that the solution can achieve the goal of reducing the demand of video decoding capability in the display terminal.
