摘要
传统广播电视监测系统的数据处理速率慢,导致监测效果差,对此提出云计算技术在广播电视监测系统中的应用方法。构建系统整体架构,选择数字电视发射机机型,定位数字电视监测节点,实现监测数据的传输、处理与存储。对音视频播出信号进行监测,通过云计算技术同步化管理多源数据,采用尺度间小波系数降噪处理数据,调度监测资源,判断异态并发出报警,利用多画面显示信息。实验结果表明,系统响应时间在3 s以内,需求覆盖率为99.1%,各模块的bug率低于3%,效果较好且具有一定的可行性。
The data processing rate of traditional radio and television monitoring system is slow, resulting in poor monitoring effect. In this regard, an application method of cloud computing technology in radio and television monitoring system is proposed. Build the overall structure of the system, select the digital TV transmitter model, locate the digital TV monitoring node, and realize the transmission,processing and storage of monitoring data. Monitor audio and video broadcast signals, manage multi-source data synchronously through cloud computing technology, use inter-scale wavelet coefficients to reduce noise, process data, schedule monitoring resources,determine abnormality and issue alarms, and use multi-screen display information. The experimental results show that the system response time is within 3 s, the demand coverage rate is 99.1%, and the bug rate of each module is less than 3%, which is effective and feasible.
