摘　　要：随着数字化、网络化进程的不断提高,安防产业的快速发展,NVR作为新一代视频监控的代表产品已经逐渐取代DVR的地位。但随着NVR接入前端IPC设备数量和质量的不断提高,保证客户端在低带宽环境下多通道预览的实时性是具有重要价值的。本文以海思3535平台为基础,提出并设计了一种视频拼接预览方案,将需要网传的多通道码流拼接编码成单通道码流供客户端使用。经过验证测试,该方案成功将16个D1码流拼接编码成1个D1码流,并在客户端显示,有效的降低了客户端多通道画面预览所需的码流带宽,保证了在低带宽环境下客户端预览的实时性。With the continuous improvement of the digital and the networking, and the rapid development of security industry. As the representative of a new generation of video monitoring products, NVR has gradually replaced the status of the DVR. However, with the continuous improvement of the quantity and quality of front-end IPC devices accessed by NVR, in order to meet real-time for Multi-channel previews on client in the networks with low bandwidth, it has an important value. This document was based on hi3535 platform, it put forward and designed a solution of video stitching preview, Stitched and coded the multi-route flows which need transferred over the network into one route flows for the client. Through the verification testing, this project successfully stitched and coded sixteen D1 streams into a D1 stream, and displayed on the client. It effectively reduces the network bandwidth that need by Multi-channel previewing on client, ensures the real-time for client preview in low bandwidth environment.
