摘　　要：为了解决车载实时视频传输问题,本文提出了一种车载实时视频流协议。使用Hi3520D作为车载核心芯片,通过TCP协议传送自行设计的视频控制协议与视频流传输协议,公有云上的服务器将视频流数据转发给客户端。该视频流实时传输协议经过测试,传输QCIF和CIF格式视频,可实时播放。In order to solve the real-time video transmission of the vehicle,an in-vehicle real-time video stream protocol is proposed.The Hi3520 Dis used as the core chip,and the self-designed video control protocol and the video stream transmission protocol are transmitted through the TCP protocol.Then the server on the public cloud transports the video stream data to the client.The video real-time stream transmission protocol is tested and transmitted in CIF and QCIF format video.The video can play in real time.
