PURPOSE: A school broadcasting system is provided to independently recognize the login of an administrator and a user in a server through an administrator DB and a user DB to selectively output D-BRO(Digital Broadcasting window) or D-LAB(Digital Laboratory window). CONSTITUTION: A server(20) independently recognizes the login of an administrator(10) and a user(10a) through an administrator DB(31) and a user DB(32). When the administrator logs in, the server outputs D-BRO in an administrator window. When the user logs in, the server outputs D-LAB in a user window. Broadcasting content is outputted in a speaker(50) of classrooms by D-BRO. A test or wave file is outputted in the speaker by D-LAB.
