Description:
<jats:p>This essay presents the basic function and structure of shared multimedia didactical system,raises a scheme relating to the system which is based on computer network and central control equipment ,and able to achieve the multistage controlling to coordinate the control center with the classrooms,analyzes the technique of realizing it,especially the key technique;introduces its operational principle as well as clarifies the methods to develop and operate it.
Traditional teaching methods depend on blackboard and textbooks,which have many limitations not only on the category and ability to bear information but also on the convenience of using.With the high development of techniques of electron,communication and computer handling,massive electronic media merges,such as slide show,projection,sound recording,filming,videotape and so on.However,these contemporary teaching media have better abilities and convenience than that of traditional ones,and have already been applied in teaching.In the process,multimedia education can rationally select and apply modern didactical facilities,as well as work with traditional media so that students can study in a better circumstance and easily acquire more new and overall information.With the rapid development of computer and other related techniques,traditional multimedia classrooms came to appear,disposing projection machine,computer,video revealing plat,video tape recorder,video disk machine and so on.It is very inconvenient for lectures to play video or audio information via operating tele-controller or plat of device,even being ready to inter-cut signal line at any time.To such a case,we recommend adopting the didactical system of compositive multimedia sharing,which consists of one control of center and many multimedia classes relying on computer network and realizing its multistage control by developing corresponding software and hardware.</jats:p>
