The teaching programs in the central node are transferred to the teaching terminals , while the request of terminals can be feed back to the central node . thus , the broadcasting of teaching programs can be controlled at both the terminals and the central node , and many functions such as teachings by tv or computer can be carried out . the central node of this distance teaching system is consisted of a smart server controller , which provides the transmission ports , and a program controller , which manages the switch of teaching programs 實(shí)現(xiàn)遠(yuǎn)程教育的方法很多,本文主要目的是從學(xué)校遠(yuǎn)程教學(xué)的角度出發(fā),并結(jié)合傳統(tǒng)學(xué)校教學(xué)的特點(diǎn),構(gòu)建一種基于遠(yuǎn)程教育的校園多媒體綜合教學(xué)網(wǎng)絡(luò)系統(tǒng),可以把位于學(xué)校主控中心教學(xué)節(jié)目源的教學(xué)內(nèi)容傳送到各種教學(xué)節(jié)點(diǎn)上,同時(shí)教學(xué)節(jié)點(diǎn)的教學(xué)情況也可以回傳到主控中心,雙方可以實(shí)現(xiàn)雙向控制教學(xué)節(jié)目的播放,實(shí)現(xiàn)具有遠(yuǎn)程概念的雙向電視教學(xué)、計(jì)算機(jī)教學(xué)和教學(xué)觀摩等功能。
