In order to make full use of existing resources (6M satellite broadband and excellent teaching resources) and better carry out distance education, the institute of Continuing Education in Tsinghua University has purchased PowerCreator courseware real-time recording systems, PowerCreator class broadcast system, PowerCreator study management system and PowerCreator courseware encryption system. Also, the audio-visual center of Tsinghua University purchased several sets of real-time recording systems to solve how to record fine courses. Because of the reasonable structure, comprehensive application, advanced technology and high reference value, we will introduce this case in detail.

 It can make full use of existing resources, especially satellite network. Before the procurement of PowerCreator class live broadcast system, Tsinghua University live broadcasted the teaching process with MPEG2 format, while 6M satellite network broadband only could broadcast programs of one channel. With the increasing of teaching tasks, it is urgently needed to simultaneously live broadcast programs of multiple channels. PowerCreator class live broadcast system adopts highly efficient coding algorithm, which has high compression rate and occupies less network resources. Now, Tsinghua University can live broadcast programs of nine channels at the same time.

 PowerCreator Composer reduces the cost and cycle of courseware. Before, Tsinghua always contracted out and delegated other companies to make streaming media courseware. First, record teaching videos, deliver it to the courseware company together with teaching lectures, and then the company will make use of relevant software to simultaneously handle the videos and lectures. There are many problems existing in this mode such as the long circle (typically one-hour courseware taking four hours), large investment (one subject costing RMB10 million), terrible quality (makers can not fully understand the professional knowledge). PowerCreator Composer can easily solve these problems. The streaming media courseware can automatically generate after teaching and it is no need to make courseware, so there are no questions about the quality.

 Sky Net and Ground Net complement each other’s advantages. Sky Net means satellite web while Ground Net means Internet. Both of them have their own good points. Because of the large coverage of Sky Net, poor remote mountainous areas also can receive excellent teaching resources from Tsinghua University. With an interactive feature, Ground Net can conveniently achieve the interaction between teachers and students.

 PowerCreator provides rich and varied teaching methods. The teaching mode of Tsinghua University has its unique features. So our company develops PowerCreator conference materials on-demand system in collaboration with Tsinghua. This system mainly contains following modes: account management, curriculum management, online Q & A, character chat, study statistics, courseware on-demand, class live broadcast, courseware recording and broadcasting, examinations online, system maintenance, log management, etc.
