为解决传统广播系统音质不佳,容易受干扰,维护管理复杂,互动性能差和无法指定区域进行广播问题,在VS2008平台下设计了基于以太网的数字广播系统,采用UDP传输方式,将系统服务器采集到的音频数据通过以太网传送到指定广播终端进行播放,同时采用多线程和多缓冲技术来保证系统的实时性和连续性,并分别设计了系统服务器和终端控制界面.测试结果表明,广播系统播放音质清晰,实时性良好,性能稳定.
為解決傳統廣播繫統音質不佳,容易受榦擾,維護管理複雜,互動性能差和無法指定區域進行廣播問題,在VS2008平檯下設計瞭基于以太網的數字廣播繫統,採用UDP傳輸方式,將繫統服務器採集到的音頻數據通過以太網傳送到指定廣播終耑進行播放,同時採用多線程和多緩遲技術來保證繫統的實時性和連續性,併分彆設計瞭繫統服務器和終耑控製界麵.測試結果錶明,廣播繫統播放音質清晰,實時性良好,性能穩定.

To solve the problems that the traditional broadcasting system has poor quality,vulnerable tointerference,complex maintenance management,poor interactive performance and cannot specify the broadcasting terminals,a digital broadcasting system based on Ethernet was designed over the VS2008 platform,which used UDP transmission to transmit the voice data collected by the system server to the specified terminal to broadcast through Ethernet,simultaneously used multithread and multi-buffer technology to ensure the real time and continuity of the system.The controlling GUI of the server and the terminal were designed respectively.The results indicate that the broadcasting system works with clear sound quality,good real time and stable performance.
