【摘要】：以计算机多媒体技术、网络技术、多媒体控制技术为代表的新技术不断更新,现代化教学方法也随之发展。校园网络应用的逐步普及,对学校多媒体教学提出了新的需求,即学校如何在多媒体教学应用的基础上,将传统模拟节目资源转换成为网络上可供随意点播的资源,并且能够简单方便的进行操作。随着现代化教学的进一步发展,多媒体课件得到了广泛应用,传统的示范课堂、教学技能训练和教学评估以及信息化教学中的远程教学等,都需要采取一定形式把课堂教学过程或者讲义图像录制下来,真实还原课堂,并作为精品课程资源,以迎合教育部提出的“精品课程”建设。“精品课程"建设项目的提出,有利于提高学校的教学质量和人才培养质量。应用先进的教育录播系统,将课堂实况、教师课件,按照课程进度录制,并以此建立共享资源库,方便了校际间的课程交流,知识的传播也变得简单易行。教师在授课过程中,既要保证课堂质量,又要对多媒体课件进行同步录制,既要得到高清晰度的视频文件,又要快速、方便的生成课件,因此,操作流程的简单化和智能化成为一种新的需求。在这一新的需求条件下,教育录播系统建设项目的推广和普及势在必行。本教育录播系统项目通过VGA信号的实时采集压缩,采用先进的图像识别跟踪技术,支持高清画面直播且音、视频精确同步,能够真实还原教师授课和师生的课堂互动场景,同时可以将黑板板书、讲义等制作成多媒体教学课件,供教师互相观摩学习和学生自主学习。本文主要探讨录播系统在项目管理下的建设实施,从录播系统的设计原则、关键技术及客户需求入手,通过分析项目建设的内外部环境,结合项目管理的相关知识,针对录播系统项目建设中的组织机构的设置和人员管理等问题,探讨项目管理模式下录播系统的建设,利用项目管理方法和理论,对本项目的具体方案、实施进程、存在的问题及质量控制、成本控制、风险控制等进行详细的规划设计,在理论结合实际的原则下,使整个系统能够协调一致,达到录播系统顺利运行的目的。
[Abstract]:The new technology, represented by computer multimedia technology, network technology and multimedia control technology, is constantly updated, and modern teaching methods are also developed. With the gradual popularization of campus network applications, a new demand is put forward for multimedia teaching in schools, that is, how to transform the traditional analog program resources into the resources available on the network for random demand on the basis of multimedia teaching applications. And can be simple and convenient to operate. With the further development of modern teaching, multimedia courseware has been widely used, such as traditional demonstration class, teaching skill training and teaching evaluation, and distance teaching in information teaching, etc. It is necessary to take some form to record the teaching process or handout images, to restore the classroom, and to serve as an excellent course resource in order to meet the construction of the "excellent course" put forward by the Ministry of Education. The construction project of "excellent course" is propitious to improve the teaching quality and talent training quality of the school. By using the advanced educational recording and broadcasting system, the classroom reality and teacher courseware are recorded according to the course schedule, and the shared resources database is established, which facilitates the exchange of courses between schools, and the dissemination of knowledge becomes simple and easy. In the course of teaching, teachers should not only guarantee the classroom quality, but also record the multimedia courseware synchronously. They should not only obtain high definition video files, but also produce courseware quickly and conveniently. The simplification and intelligence of operation flow has become a new demand. Under this new demand condition, it is imperative to popularize and popularize the construction project of educational recording and broadcasting system. This educational recording and broadcasting system project adopts the advanced image recognition and tracking technology through the real-time collection and compression of VGA signal, supports the high-definition picture live broadcast and the audio and video accurate synchronization, can truly restore the teacher teaching and the classroom interactive scene of teachers and students. At the same time, blackboard writing, handouts and so on can be made into multimedia teaching courseware for teachers to observe each other and students to learn independently. This paper mainly discusses the construction and implementation of video and broadcast system under project management, starting with the design principles, key technologies and customer requirements of the system, through analyzing the internal and external environment of the project construction, combining with the relevant knowledge of project management. Aiming at the problems of organization setting and personnel management in the project construction of video and broadcast system, this paper discusses the construction of the recording and broadcasting system under the project management mode, and makes use of the project management method and theory to carry out the concrete scheme and implementation process of the project. The existing problems and quality control, cost control, risk control and so on are planned and designed in detail. Under the principle of combining theory with practice, the whole system can be coordinated and consistent to achieve the purpose of smooth operation of the recording and broadcasting system.
