【摘要】：随着全球信息化进程的不断发展,教育信息化势在必行。现代教育中一个重要的教学手段就是多媒体教学,但是由于多媒体教学的存在,一些类似缺乏选择性、重技轻教、使用死板等问题都严重阻碍了教师的教学。现在的多媒体教学应当注重视听效果,设计出合理的多媒体学习资料,并且根据不同类型的学生推荐不同的视频课程,从而帮助教师完成教学目标。同时大数据技术的兴起和应用为推荐工作提供了强大的技术支持。另外直播技术的成熟与普及也使直播多媒体教学逐渐成为主流教育形式。直播多媒体教学拓展了教学的时空纬度,为学习者提供了更为丰富、优质的学习资源,这必将对提高教学质量、转变教学观念以及推进全民教育产生积极影响。本课题针对现有教学资源和管理需要,设计并实现了一个具备大数据推荐功能的直播多媒体教学系统。本系统结合了大数据推荐系统和主流直播平台的主流媒体的技术,解决了现有直播教学系统难以截取播放器画面的问题,提高了截屏和画屏的速度。在多媒体数据压缩方面,根据不同的媒体信息的特性采用了不同的压缩方式,使媒体信息在客户端能正确、同步重现;控制命令以及文件的传输使用UDP方式,并且通过应用层协议,使文件的UDP方式高效率地传递给客户端。在教学辅助的其他方面,提供了遥控辅导、文件传输、直播信息、屏幕录像等实用的功能。本直播系统的最大特色——推荐模块功能的实现,使学校的直播系统具备了商业化系统的重要功能。希望通过本论文的研究结果,能够很好地将现在热门的直播和传统的教学相结合,从而提高教学效率,减轻教师的教学负担,这在教学研究领域具有更广泛的实用价值。
[Abstract]:With the continuous development of global informatization, education informatization is imperative. An important teaching means in modern education is multimedia teaching. However, due to the existence of multimedia teaching, some similar lack of selectivity, emphasis on technology and education, The use of stereotypes has seriously hindered the teaching of teachers. Nowadays, multimedia teaching should pay attention to audio-visual effects, design reasonable multimedia learning materials, and recommend different video courses according to different types of students. At the same time, the rise and application of big data technology provided strong technical support for the recommendation work. In addition, the maturity and popularization of live broadcast technology also made live multimedia teaching become the mainstream teaching gradually. Education form. Direct broadcast multimedia teaching has expanded the space and time latitude of teaching, It will have a positive impact on improving teaching quality, changing teaching concepts and promoting education for all. This topic aims at the existing teaching resources and management needs. A live multimedia teaching system with big data recommendation function is designed and implemented. This system combines the technologies of big data recommendation system and mainstream media on the mainstream live broadcast platform. It solves the problem that it is difficult for the current direct broadcast teaching system to intercept the player picture, and improves the speed of screen capture and screen drawing. In the aspect of multimedia data compression, different compression methods are adopted according to the characteristics of different media information. The media information can be correctly and synchronously reproduced in the client, the control command and file transmission are made by UDP mode, and through the application layer protocol, the UDP mode of the file can be transferred to the client efficiently. Provides remote control guidance, file transmission, live information, screen video and other practical functions. It is hoped that through the research results of this paper, the current popular live broadcast system can be combined with traditional teaching to improve the teaching efficiency and lighten the teaching burden of the teachers, so as to make the school live broadcast system have the important function of the commercial system, and hope that through the research results of this paper, we can combine the popular live broadcast with traditional teaching. This has more extensive practical value in the field of teaching and research.
