摘　　要：在实施中央广播电视节目无线覆盖工程的实践中,发现使用总局前端统一传送的中星6A节目流时,机顶盒收看不到中央台的节目。通过对节目码流、机顶盒接收原理进行分析,找到了问题的解决办法,为此,对故障处理过程进行总结,对当前的无线覆盖工程建设具有重要的意义。In the practice of implementing the radio coverage project of CCTV programs,we found that when using the Zhongxing 6 A program stream uniformly transmitted by the front end of the general administration,the set-top box can not watch the programs of CCTV.Through the analysis of the program code stream and the receiving principle of set-top box,the solutions to the problems are found,which is of great significance to the current wireless coverage project construction.
