Research And Realization Of Multi-Screen Interactive Scheme In Future Classroom Environment

In the traditional classroom teaching, teachers and students mainly adopt the interaction form of language interaction between language and question answering,and their interactive forms and teaching scenes are single, it is difficult to meet the needs of modern teaching interaction. With the smart phones, tablet PCs and other mobile intelligent terminals are widely used in teaching, the teaching form of interactive teaching with intelligent mobile devices has emerged. And how to use intelligent mobile device terminal to improve the interaction of classroom teaching and improve the efficiency of teaching and learning, it is an important content of the future classroom planning.The future classroom is the use of new technology to create a new form of teaching and learning environment. In this paper, the design of the future classroom environment, multi-screen interaction, through the way of wireless network connection,in the classroom PCs, mobile phones, PAD and other different platforms between the terminal equipment of multiscreen display real-time content sharing, to achieve teachers?groups?students of the desktop synchronization display,to provide more effective support for the classroom group to study with students as the main mode of the teaching mode. The real-time content transmission of multi-screen interactive is based on streaming media technology to achieve, the existing streaming media and video broadcast solutions from the hardware costs and the convenience of use are difficult to meet the real-time?continuous and flexible sharing of display content needs between different devices within the classroom.In view of the above problems, this paper presents a software solution for multi-screen interaction in the future classroom environment based on the analysis of the existing technologies such as streaming media, sends the real-time display content of any role device in teachers, students or groups to other terminals and dynamically presented in real-time. In order to ensure the real-time transmission speed, this paper through the integration of multiple technical framework, and solve the key issues such as efficiency, ultimately achieve the multi-screen interactive of smooth and stable, and use convenient.The main work and innovation of this paper is to design a software solution architecture, a streaming media server and a client based on one-to-many content sharing between multi-platform display devices such as teachers, students and groups in the multi-screen interactive scene of classroom; Secondly, after the acquisition of the contents of the display code to form a video stream, and then send the video stream to the cache of the inverter, and then sent to the receiver through the inverter, combined with Live555 and VLC framework, and to improve the Live555 , solve the Live555 does not support the problem of reading from the memory, the design of a memory source can read the flow of the device, achieve the multi-platform device display content of each other push; Thirdly, in order to ensure the clarity and fluency, the framework of the interface, coding technology, communication mode, streaming media services, key frames, rate control, receiving decoding, and so on are improved and optimized.Experiments conducted in the context of actual future classroom typical equipment configurations show that the optimization measures in this solution are reduced in bandwidth and effectively reduce latency. The program from the receiver to show the synchronization, fluency and clarity, etc., have shown that it meets the real-time classroom interaction and quality requirements.The solution of this paper will be integrated into the cloud integrated teaching platform starC3, and deployed to the wisdom of the classroom trial test,followed by a larger scale to promote the application.
