The live broadcast of the common league mainly adopts the design of streaming media data block by block. The secondary processing of streaming data is carried out on the server-side. It results in a higher delay during a live broadcast. The higher delay has numerous disadvantages during broadcasting for delay-sensitive applications. We have to solve the delay problems during a live broadcast. Therefore, in this paper, we optimize the synchronization of the tennis professional league live broadcast based on wireless network planning. In the proposed scheme, the 3D detection target model is first constructed, and the background is extracted from the moving video image. The extraction is performed using the interframe difference elimination algorithm, and the target motion trajectory is predicted. Then the phase difference characteristics of the image foreground trajectory are analyzed by the Hilbert transform to detect target missing points. By observing the vertex structure of the target missing point, the phase Fourier transform frame is constructed. Finally, the synchronization of the league live broadcast is encoded and decoded. Based on the timestamp, the synchronization optimization of the tennis professional league live broadcast is completed. The experimental results show that the synchronization optimization method has good synchronization, high resolution, short reaction time, and good detection effect.

基于无线网络规划的网球职业联赛直播同步优化

普通联赛的直播主要采用流媒体数据逐块的设计。流数据的二次处理在服务器端进行。这会导致直播期间的延迟更高。对于延迟敏感的应用程序，较高的延迟在广播期间具有许多缺点。我们必须解决直播过程中的延迟问题。因此，本文基于无线网络规划对网球职业联赛直播的同步进行优化。在所提出的方案中，首先构建3D检测目标模型，并从运动视频图像中提取背景。采用帧间差分消除算法进行提取，预测目标运动轨迹。然后通过希尔伯特变换分析图像前景轨迹的相位差特征，检测目标缺失点。通过观察目标缺失点的顶点结构，构建相位傅里叶变换框架。最后对联赛直播的同步进行编解码。基于时间戳完成网球职业联赛直播同步优化。实验结果表明，该同步优化方法同步性好、分辨率高、反应时间短、检测效果好。联赛直播的同步编码和解码。基于时间戳完成网球职业联赛直播同步优化。实验结果表明，该同步优化方法同步性好、分辨率高、反应时间短、检测效果好。联赛直播的同步编码和解码。基于时间戳完成网球职业联赛直播同步优化。实验结果表明，该同步优化方法同步性好、分辨率高、反应时间短、检测效果好。
