With the development of science and technology, education informatization is an inevitable trend of development. How to use science and technology to help improve the level of education and teaching, and better develop, manage, and share educational resources is the goal of educational technology development. However, in the actual teaching process, there is often such a problem. In order to record a complete classroom video, it often takes a long time to make careful preparations, and there must be a special person on site to record, and it must be equipped with corresponding sound pickup equipment. Recording audio, this situation not only caused a waste of time and energy, but the recorded educational resources cannot be stored, managed and shared in a timely and effective manner.
In order to solve the above problems and better optimize the application process of educational technology, Synchronous Technology has developed a series of solutions, in which the educational resource recording system can automatically record the teaching videos taken by each machine in the classroom according to the submitted automatic course application , Without personnel on duty. All the recorded educational resources can be stored and managed in a unified manner, and the recorded video can be live broadcasted or ordered on-line. This system can be seamlessly connected with the synchronous data remote transmission system, distributed transcoding system, and power management system, creating a system for energy-saving management of video and audio signal transmission, recording, storage, management, sharing, transcoding, output, and equipment Digital application platform.
system applications
Ø Automated course recording method Teachers only need to submit an application for recording a course in advance, and they can easily complete automatic recording of video and audio content, and realize automatic unattended recording. While submitting the application, teachers can also enter information related to the recorded course, such as teaching goals, teaching difficulties and other related information, so that the educational resources are more optimized and targeted.
Ø Course recording approval
After the teacher's application for recording the course is approved, the result of the approval will be automatically recorded in the system's database, and the system will automatically start and stop the course recording process according to the arrangement of the course.
Ø Resource management
The system can manage personnel, etc., through account settings, you can set different permissions for different users and management personnel, to provide protection for system management and security. In addition, related resources can also be set.
Ø Unified storage and management of course resources
The recorded education resources are stored and managed by the intelligent storage system in a unified manner. The relevant operators can retrieve the courses, and set the course publicity, whether it can be evaluated, graded and other related settings.
Ø Online live classroom teaching site
The system provides a live broadcast of the teaching site content, you can easily click to watch multimedia courseware, classroom lecture live, live live and other angles of the teaching site, you can also see relevant introductions about teachers, courses, etc. While watching the live broadcast, you can also make relevant evaluations as needed, increase interaction between teachers, and facilitate mutual learning with teachers and improve teaching levels.
Ø On-demand wonderful classroom content after class
The recorded classroom videos can be watched on-demand on the Internet. Teachers can observe themselves and improve the quality of teaching through the on-demand classroom videos after class; students can watch and learn again on demand; even parents can learn more about student learning through on-demand .
System Features
Ø High quality video and audio recording
Through seamless connection with the integrated data remote transmission system, using optical signal transmission, from transmission to collection, the signals picked up by classrooms, blackboards, students, computer playback screens, DVD screens and audio equipment in the course of lossless recording and recording are guaranteed. Maintain the original video and audio quality.
Ø Multi-screen selection for viewing
Whether it is live or on-demand webcast, you can selectively switch the screen you want to watch in the multi-channel screen.
Ø Easily zoom and move to watch educational resource content
The system provides a zoomed viewing method to watch the required classroom content at close range. In addition, through the mobile viewing mode, you can view all the pictures taken in the classroom.
Ø Abnormal time continuous recording ability The system has the ability of continuous time course recording, without the trouble of changing tape, card or disk.
Ø High-reliability and technical guarantee system The high-reliable technical guarantee system can guarantee the security of video recording.
Application platform
Ø Seamlessly connect with the integrated data remote transmission system to easily complete the transmission of data in various teaching
The synchronous remote integrated data transmission system is a multi-channel video and audio optical transmission system, which can be used to solve the high-quality real-time transmission of long-distance, high-bandwidth multi-channel high-definition video and audio recording of educational resources, and provides early signal layout and recording for educational resource recording systems For convenience.
Ø Seamlessly connect with the distributed transcoding system to complete the ultra real-time conversion of the required video format
The educational resource management system can be seamlessly connected with the distributed transcoding system. With powerful conversion capabilities, the material can be converted into video files or video streams in multiple formats at the same time, while satisfying resource storage, webcast, video editing, video in education Many different needs such as on-demand, CD burning, etc.
Ø Seamless connection with power management system to achieve safe, efficient and energy-saving equipment management.
All equipment in the system can be managed uniformly through the power management system. It can remotely control and manage the power through the computer, the Internet, and the 3G network of the mobile phone; so that all equipment in education and teaching can be managed uniformly, improving work efficiency, And achieved the purpose of intelligent safety and energy saving.
Applications
On December 25, 2009, Synchronous Technology won the bid for the multimedia teaching project of the Chaoyang District Modern Education Technology Information Network Center.
The project is built on the basis of Beijing Xinghe Experimental Primary School. It was built in 2007 and is a public school supported by Beijing Municipality. It is a high starting point school directly supported by the Chaoyang District Education Commission. With the philosophy of "taking quality as life, promoting development with science, opening education walls, and opening an open international brand school", the school has rapidly developed into a prestigious school with a good reputation.
In order to make the high-quality teaching resources of Xinghe Experimental Primary School convenient for internal and external communication, Synchronous Technology specially designed and developed application platforms such as distributed coding, educational resource recording, 3G bandwidth multi-signal format transmission, and remote power management. The project realized the live broadcast of four channels of high-definition signals, through the high-quality recording and preservation of the teaching process, and the promotion of Ma Xinlan's teaching methods and effects with high-quality video and audio teaching resources to achieve a larger range of radiation to surrounding schools The purpose is to achieve the sharing of high-quality educational resources.
