摘　　要：为了给予用户更加良好的直播交互体验,设计了基于云架构的全媒体交互式直播系统。该系统可以在硬件设备的支撑下,将直播内容导入云端监控,通过节点建立用户端与直播终端的通信与交互请求,计算云端直播通信传输节点权值,实现对节点信息的动态更新与缓冲请求。此外,该系统引进了帧差分析法比较直播画面中两个相邻帧,采用重新调整或设定阈值的方式,动态调整直播画面帧,实现对直播画面帧差的连续化处理。对比实验结果证明,开发的直播系统可以在提高同步在线人数的同时,保证直播展示界面保持较高的清晰度与流畅度。In order to give users a better live interactive experience, an all media interactive live broadcast system based on cloud architecture is designed. Select the system hardware equipment, and under the support of the hardware equipment, import the live broadcast content into the cloud monitoring, establish the communication and interaction request between the user end and the live broadcast terminal through the node, calculate the weight of the cloud live broadcast communication transmission node, and realize the dynamic update and buffer request of the node information;The frame difference analysis method is introduced to compare two adjacent frames in the live broadcast picture, and the live broadcast picture frame is dynamically adjusted by readjusting or setting the threshold value to realize the continuous processing of the live broadcast picture frame difference. Design a contrast experiment, and the experimental results prove that the live broadcast system can improve the number of synchronized online people, while maintaining a high definition and fluency of the live broadcast display interface.
