摘要
随着地面数字电视(Digital Television Terrestrial Multimedia Broadcasting,DTMB)技术在广播电视领域的应用范围不断扩大,如何准确评估DTMB异构分配网络的覆盖效果并精准定位用户端广播电视节目信号的接收质量,是一个值得深入研究的问题。通过分析影响DTMB网络覆盖效果评估的因素,提出一种基于位置精准性识别算法的DTMB网络覆盖效果评估方案,即利用多源位置信息匹配用户轨迹的同时,精准识别地理位置数据。经过对比验证,该方案大幅提升了DTMB网络覆盖效果评估的精确度。
With the continuous expansion of the application of Digital Television Terrestrial Multimedia Broadcasting(DTMB)technology in the field of radio and television,how to accurately evaluate the coverage effect of DTMB heterogeneous distribution network and accurately locate the reception quality of radio and television program signals at the user end is a problem worthy of indepth study.By analyzing the factors that affect the coverage evaluation of DTMB network,this paper puts forward a coverage evaluation scheme of DTMB network based on location accuracy identification algorithm,that is,using multi-source location information to match user trajectories and accurately identify geographical location data.After comparison and verification,the scheme greatly improves the accuracy of the evaluation of DTMB network coverage effect.
