Special:Badtitle/NS90:Milestone-Proposal talk:Emergency Warning Code Signal Broadcasting System/Queries to Proposer/reply (5)

Dear Mr.Sampathkumar Veeraraghavan,

We would appreciate if we could have your help to improve the citation. Let us share the fact that the code signals transmit within the bandwidth of audio frequency. The code signals are within the audio of analog radio and digital TV. While the TMCC signaling is specifically for digital system. Below is a draft version.

The emergency warning broadcast system in Japan has been successfully in operation since 1985, after NHK (Japan Broadcasting Corporation) developed the system having code signals forming a special pattern. The system provides reliable and prompt transmission of emergency warning information to the public. Today, both in analog radio and digital television services, the system guarantees the transmission of emergency information at any time when needed.

Thank you very much for your kind support in advance.
