摘要： PURPOSE: A multimedia electronic lecture system is provided to prevent unnecessary power consumption, by automatically blocking the power supply to a device if a multimedia device is judged to be in a non-operational state after it is operated. CONSTITUTION: It is judged whether a lecture start key is operated(210). If a lecture start key signal is received, a main control unit turns off a lamp of a lecture room(220). The main control unit judges whether a human body sensing signal is received(230). If the human body sensing signal is not received, it is judged whether another image signal is received through an image input part(240). If another image signal is not received, all the power sources of a multimedia device are turned off(250). If the human body sensing signal is received, it is judged whether a computer operation signal is received(260). If the computer operation signal is not received and another image signal is received, a power source supplied to the computer is blocked(265). If the computer operational signal is received, it is judged whether an electrical screen is in a rolled state(270). If a signal indicating the rolled electrical screen is received, the main control unit maintains the power supply only to the computer and turns off the power source of the other multimedia device(280). If the electric screen maintains its unfolded state, the main control unit judges whether a motion signal is received(290). If the motion signal is not received, all power sources are turned off by judging that the multimedia device is not used. If the motion signal is received, the operational state of the multimedia device maintains the current state(300), and it is judged whether a lecture end signal is received(310). If the lecture end signal is received, the power source of a device under operation is blocked(310). [Reference numerals] (210) Is a lecture start signal received ?; (220) Turn off a lamp of a lecture room; (230) Is a human body sensing signal received ?; (240) Is another image signal received ?; (250) Turn off power sources of a multimedia device; (260) Is a computer operation signal received ?; (265) Turn off a computer; (270) Is a proximity sensor signal received ?; (280) Maintain power supply to only the computer; (290) Is a camera motion signal received ?; (300) Maintain a current state; (310) Is a lecture end signal received ?; (AA) Start; (BB,DD,FF,II,JJ,LL,NN) No; (CC,EE,GG,HH,KK,MM,OO) Yes
摘要翻译：目的：提供一种多媒体电子讲座系统，以防止在操作多媒体设备后处于非操作状态时自动阻止对设备的电源的不必要的功耗。构成：判断演讲开始键是否被操作（210）。如果接收到讲话开始键信号，则主控制单元关闭讲座室（220）的灯。主控制单元判断是否接收到人体感测信号（230）。如果未接收到人体感测信号，则判断是否通过图像输入部（240）接收另一图像信号。如果没有接收到另一个图像信号，则多媒体设备的所有电源都被关闭（250）。如果接收到人体感测信号，则判断是否接收到计算机操作信号（260）。如果未接收到计算机操作信号并且接收到另一图像信号，则阻止向计算机提供的电源（265）。如果接收到计算机操作信号，则判断电子屏幕是否处于滚动状态（270）。如果接收到指示滚动的电屏幕的信号，则主控制单元仅将电源保持到计算机并且关闭另一个多媒体设备（280）的电源。如果电屏幕保持其展开状态，则主控制单元判断是否接收到运动信号（290）。如果未接收到运动信号，则通过判断不使用多媒体设备来关闭所有电源。如果接收到运动信号，则多媒体装置的运行状态保持当前状态（300），并且判断是否接收到讲话结束信号（310）。如果接收到讲话结束信号，则被操作的设备的电源被阻塞（310）。（附图标记）（210）接收到讲话开始信号α; （220）关闭演讲室的灯; （230）是否接收到人体感知信号？（240）是否接收到另一个图像信号？（250）关闭多媒体设备的电源; （260）是否接收到计算机操作信号？（265）关闭电脑; （270）接收传感器信号？（280）仅维护电脑供电; （290）是否接收到摄像机运动信号？（300）保持现状; （310）是否收到演讲结束信号？（AA）开始; （BB，DD，FF，II，JJ，LL，NN）否; （CC，EE，GG，HH，KK，MM，OO）是的

摘要： 본발명은실시간양방향데이터전송이가능한스마트전자교탁시스템에관한것으로서, 강의실마다설치되며강의자가보유한마스터단말기와수강자가보유한슬레이브단말기와정보공유를지원할수 있도록된 전자교탁과, 전자교탁과통신망을통해접속되며강의자들과관련된정보가기록된학교서버와, 강의실에설치되며전자교탁에의해제어되어수강자에게표시정보를표시하는메인표시기를구비하고, 전자교탁은마스터단말기를통해접속을시도하는강의자에의해입력된고유정보가접속된학교서버에등록된정보와일치하면마스터단말기의접속을허용하고, 작동을개시하는작동온키가조작되어작동이개시되면, 슬레이브단말기의접속을허용하기위한억세스고유정보를발생하여메인표시기에표시하고, 억세스고유정보는작동온키가조작될때마다변경되게생성하도록되어있다. 이러한스마트전자교탁시스템에의하면, 전자교탁이가동되면억세스고유정보를프로젝터또는전자칠판과같은메인표시기에표시하여강의실내의수강자로접속을제한할수 있고, 강의자가이용하는마스터단말기에로딩된파일들에대해서는마스터단말기의화면표시와관계없이수강자가사용하는슬레이브단말기에전송함으로서, 로딩된파일의특정페이지가마스터단말기에화면에표시될때 슬레이브단말기의화면에연동되어데이터전송지연없이로딩시킬수 있도록지원하는장점이있다.
摘要翻译：本发明涉及一种能实时双向数据传输的智能电子讲台系统。智能电子讲座包括：安装在每个演讲室中的电子讲台，以支持由讲师所拥有的主终端和受训者所拥有的从属终端之间的信息共享; 记录通过通信网络访问电子讲台的学习服务器，记录与讲师有关的信息; 并且安装在演讲室中的主显示装置由电子讲台控制，并向受训者显示显示信息。当通过主终端尝试访问电子讲座的讲师输入的特定信息与登记在所访问的学校服务器中的信息相匹配时，电子演讲台允许主终端的访问，生成访问特定信息以允许访问操作开始操作的操作键开始操作时的从属终端，并且在主显示设备上显示生成的访问特定信息。每当操作操作键被操作时，访问特定信息被不同地生成。根据这种智能电子演讲台系统，当电子演讲台被操作时，在主显示装置（例如投影仪或电子黑板）上显示访问特定信息，从而限制了在演讲室中的学员的访问。由讲师使用的主终端中加载的文件，无论主终端的画面显示如何，均被传送给实习生使用的从属终端。因此，具有这样的优点：当在主终端的屏幕上显示加载的文件的特定页面时，可以通过与从属终端的屏幕互通而不传输延迟来加载数据。
