| Abstract: | In this paper,4G wireless router of telecommunications operator is used to receive network streaming media,and multiple FM broadcasting sources are output by a computer.Then emergency backup of the sources in unmanned alpine transmitting and broadcasting station is realized through emergency switcher.At the same time,through FRP intranet penetration technology,VNC is used to realize remote desktop function.The paper realizes secure real-time broadcasting control,which can be a reference for low-cost implementation of source backup of transmitter replacement sites. |
