    • A remote controlling system for a public address sound system is provided to perform selective broadcasting in the whole area or a designated area to manage the public address sound system optimally. A remote controlling system for a public address sound system includes a plurality of amps(300), a plurality of speakers(400), a sound source generating unit(10), a matrix switch(30), a testing apparatus(50), a control computer(90), and a controlling apparatus(70). The matrix switch connects the output of the sound source generating unit with the combination of at least one amp and the speaker. The testing apparatus is electrically connected with the amps and the speakers, and tests the amps and the speakers. The control computer sets the combination of the amp and the speaker according to the input information of a broadcasting menu, and generates a connection control signal of the combination of the amp and the speaker according to the setting. The controlling apparatus transmits an output signal of the testing apparatus to the control computer, and drives the matrix switch according to the connection control signal of the combination of the amp and the speaker of the control computer. The broadcasting setting menu of the control computer includes a broadcasting menu and a sub broadcasting menu. The broadcasting menu includes morning broadcasting, lunch broadcasting, finishing broadcasting, and emergency broadcasting. The sub menu includes broadcast state check, broadcast state change, broadcast subscription, broadcasting by grades, and overall broadcasting. When the broadcast state check or the broadcast state change is selected, the testing apparatus is driven and detects the states of the amp and the speaker which are displayed on the control computer. When the emergency broadcasting is selected, the predetermined channel is put in the first priority.
    • 提供用于公共广播音响系统的远程控制系统,以在整个区域或指定区域中进行选择性广播,以最佳地管理公共音频系统。 一种用于公共音频系统的遥控系统包括多个放大器(300),多个扬声器(400),声源产生单元(10),矩阵开关(30),测试装置(50) 控制计算机(90)和控制装置(70)。 矩阵开关将声源产生单元的输出与至少一个放大器和扬声器的组合连接。 测试装置与放大器和扬声器电连接,并测试放大器和扬声器。 控制计算机根据广播菜单的输入信息来设置放大器和扬声器的组合,并且根据该设置产生放大器和扬声器的组合的连接控制信号。 控制装置将测试装置的输出信号发送到控制计算机,并根据控制计算机的放大器和扬声器的组合的连接控制信号驱动矩阵开关。 控制计算机的广播设置菜单包括广播菜单和子广播菜单。 广播菜单包括早播,午餐广播,整理广播和应急广播。 子菜单包括广播状态检查,广播状态改变,广播订阅,按等级广播和整体广播。 当选择广播状态检查或广播状态改变时,测试装置被驱动并且检测在控制计算机上显示的放大器和扬声器的状态。 当选择紧急广播时,预先确定的频道处于第一优先级。

    • An object-based 3-dimensional audio service providing system and method using preset audio scenes are provided to offer previously generated preset audio scenes to users such that the users do not personally control audio signals and easily use object-based audio service. A 3-dimensional audio service providing system includes an audio input unit(31), an audio scene generator(32), an encoder(33), and a transmitter(34). The audio input unit receives an audio signal. The audio scene generator extracts object audio signals from the received audio signal, arranges the extracted object audio signals in a 3-dimensional space, and edits attributes of the object audio signals to generate at least one 3-dimensional audio scene. An encoder encodes the audio signal and the 3-dimensional audio scene. The transmitter converts the encoded object-based 3-dimensional audio scene according to a transmission format and transmits the object-based 3-dimensional audio scene to an audio playing terminal(40) through a digital broadcasting network(50).
