摘　　要：为了减少广播电视信号发射时信号数据丢包次数较多而影响广播电视节目的正常传输与接收等问题,提出一种广播电视信号无线发射技术。利用无线发射技术采集广播电视信号,基于采集的信号建立信号模型,分析信号数据传输链路,根据信号接收端设备的信号接收情况对信号发射端链路进行校准,以保证接收到的信号数据完整无误。实验结果表明,在不同通信距离条件下,设计的无线发射技术丢包次数较少,具有较好的信号传输稳定性与可靠性,能够保证广播电视节目的完整播出,可以很好地应用于广播电视信号传输。In order to reduce the problem that the number of signal data packets lost during the transmission of radio and television signals affects the normal transmission and reception of radio and television programs,a wireless transmission technology of radio and television signals is proposed.Wireless transmission technology is used to collect radio and television signals.Based on the collected signals,a signal model is established,and the signal data transmission link is analyzed.According to the signal receiving situation of the signal receiving end equipment,the signal transmitting end link is calibrated to ensure that the received signal data is complete and correct.The experimental results show that under different communication distances,the designed wireless transmission technology has fewer packet loss times,better signal transmission stability and reliability,and can ensure the complete broadcast of radio and television programs,and can be well applied to radio and television signal transmission.
