Embodiment Construction

[0020] As shown in Fig. 1, the present invention includes: an audio and video collection tool, an electronic document collection tool, a synchronous teaching support platform, and a synchronous courseware browsing tool. The audio and video collection tool is responsible for collecting and compressing the audio and video signals of the teaching site, and sending them to the synchronous teaching support platform. The electronic document collection tool is responsible for collecting the screen data taught by teachers in real time, compressing them into Web pictures and sending them to the synchronous teaching support platform. The synchronous teaching support platform receives the audio and video teaching scene and the teacher's teaching screen data, organizes the three media of audio and video data and screen data synchronously, performs live broadcast service to the synchronous courseware browsing tool after streaming, and provides on-demand service.

Abstract

A network-based multi-media real-time synchronous teaching system in the field of network technology, including: audio and video collection tools, electronic document collection tools, synchronous teaching support platforms, and synchronous courseware browsing tools. The video signal is sent to the synchronous teaching support platform; the electronic document collection tool is responsible for collecting the screen data taught by the teacher in real time, compressing it into a Web picture and sending it to the synchronous teaching support platform; On-site audio and video teaching data, while receiving the teacher’s teaching screen data collected by electronic document collection tools, synchronously organizing the three media of audio and video data and screen data, after streaming, provide live broadcast services to the synchronous courseware browsing tool, and provide on-demand services . The invention realizes the characteristics of powerful function, high efficiency and quickness, simple operation, friendly man-machine interface and the like.

Description

technical field [0001] The invention relates to a system in the field of network technology, in particular to a network-based real-time multi-media synchronous teaching system. Background technique [0002] In the past five years, China's online education software market has been expanding rapidly with a growth rate of more than 40%. However, the current situation of China's online education is still far behind the level of developed countries in the world, and China's online education still has huge growth potential. Looking at the products in the field of online education at home and abroad, most of them are based on Microsoft's Windows operating system and network multimedia technology platforms with foreign copyrights. In the context of the country's strong support for domestic operating systems and various supporting application systems, it is of great significance to develop an online education platform based on domestic Linux. The Linux platform has advantages that ...
