2.2 IPBoard recording and live broadcast system

The intelligent recording and broadcasting live broadcast system mainly completes the automatic tracking and acquisition of teachers and students' videos, intelligent audio acquisition and screen interception of teachers' electronic whiteboard. The above signal sources are automatically transmitted to the courseware real-time recording system to generate high-quality excellent courses. At the same time, the interactive live broadcast system is used to broadcast live on LAN and Internet, providing a real-time online learning platform for remote users.

The main body of the system is divided into five subsystems:

Teacher tracking system Teacher tracking system is an intelligent system that uses image recognition and tracking technology to automatically track and take pictures of teachers' whole teaching activities.

Student Positioning System The student positioning system is an intelligent system, which can automatically locate the students who are talking in real time and take close-ups shots.

Intelligent Audio System The intelligent audio system mainly realizes that the voice signals of teachers and students answering questions or discussing in class are collected through the intelligent mixer and transmitted to the courseware recording system in real time, so as to complete the real-time recording of courseware.

The courseware real-time recording system can record the whole classroom scene in real time very simply and conveniently, and generate streaming media courseware with audio and video and electronic documents. And the compression ratio is very high, and the functions of dynamically grabbing and automatically generating a text index can be realized.

Interactive live broadcast system plays class content through IP network (such as LAN and Internet). The classroom content includes audio, video and computer screen content, and the receiving end can watch the live classroom content through IE browser.

The main subsystems are introduced in 2.2. 1. Teacher tracking system.

The teacher tracking system adopts the most advanced tracking technology-image recognition technology to automatically track the subject. The teacher tracking system completely adopts unattended operation mode, and the whole tracking work process does not need manual intervention. In the classroom, teachers only need to carry out normal teaching activities according to the usual class mode, and they can complete tracking shooting without wearing any equipment, which eliminates the discomfort of teachers and makes them more focused on teaching activities. Whether the teacher walks around the classroom quickly or writes on the blackboard, the system can accurately adopt different strategies to automatically zoom and track the shooting. The whole tracking process is continuous, stable and smooth, and the whole picture output is very stable.

2.2. 1. 1 tracking strategy 1) When the teacher is not walking around lecturing or writing on the blackboard, the tracking system automatically focuses and takes close-up shots;

2) When the teacher walks into the classroom, the tracking system automatically focuses and takes close-up shots;

3) When many people appear on the podium at the same time, the tracking system automatically focuses and shoots the middle scene;

2.2. 1.2 main functions and characteristics

autotrack

The tracking range is not limited to the camera's inherent field of vision, but within the scope of the whole teaching activity. No matter what the teacher is doing, it can automatically track without blind spots.

Real-time close range tracking

When tracking, the system automatically takes a close-up shot of the tracked object, so that the tracked object always becomes the focus of the picture, which meets the requirements of shooting people and avoids the problem that the tracked object cannot be close-up when tracking by using the induction area positioning method. This function is especially important for classes with more blackboard writing.

fully automatic

Tracking and camera shooting can be completed automatically by the system without the help of operators, and the whole tracking process is very close to manual shooting;

Strong anti-interference ability

The tracking system is not affected by external environment such as sound, electromagnetic wave, infrared ray and light, and has strong anti-interference ability;

Teacher's other tracking equipment

The tracking system adopts advanced image recognition technology without wearing or operating any tracking equipment on teachers.

Easy installation

The tracking system adopts advanced image processing technology, which has no special requirements for the environment, and does not need to install any sensing equipment or carry out any construction, thus greatly reducing the workload of installation and construction.

2.2.2 Student Positioning System

The student positioning system is an intelligent system, which can automatically position the students who are talking in real time and take close-ups When students stand up to speak or answer questions, the student positioning system will automatically call the student camera to position the students who are speaking and take close-up shots.

2.2.2. 1 positioning strategy 1) When students stand up to answer questions, the teacher tracking system is automatically controlled by the student positioning system, which automatically positions the standing students for close-up shooting at the same time, and the system automatically returns to the teacher tracking system after the students answer;

2) When the teacher tracking system does not find the tracking target on the platform, it is automatically controlled by the learning positioning system, and the student positioning system is automatically adjusted to panoramic shooting;

2.2.2.2's main function and characteristics-intelligent positioning.

The whole system automatically completes the student positioning, without manual intervention, and can perfectly shoot all the details without missing any students who speak;

◇ Close-up shooting

At the same time, the system will automatically zoom to provide close-ups for the students who speak. It solves the problem that traditional shooting methods can't provide students with close-range shooting.

Automatic return

After the students finish speaking, the system automatically switches to the teacher's lens;

Strong anti-interference ability

The tracking system is not affected by external environment such as sound, electromagnetic wave, infrared ray and light, and has strong anti-interference ability;

No other tracking equipment is needed.

The tracking system adopts advanced image recognition technology, without operating any tracking equipment or using infrared tracking microphone;

Intelligent audio system

The intelligent audio system mainly realizes that the voice of the teacher when teaching and the voice of the students answering questions or discussing in class are holographic collected by the intelligent mixer and transmitted to the courseware recording system in real time to complete the classroom recording.

2.2.3. 1 main equipment

According to the sound characteristics in the teaching process, the teacher uses the desktop interface microphone, and according to the special situation of the students, the students use the lifting interface microphone, and the pickup distance is far, which can ensure every position in the classroom. Students can collect the answering sound when answering questions, and eliminate the tuner through digital feedback, so there will be no noise and good sound effect.

2.2.4 courseware real-time recording system

It is very simple and convenient to record the whole classroom scene in real time and generate streaming media courseware with audio and video and electronic documents. And the compression ratio is very high, and the functions of dynamically grabbing and automatically generating a text index can be realized.

2.2.4. 1 system function

Dynamic screen capture can completely record the contents of computer screen, including mouse movement trajectory, electronic whiteboard content and so on. When recording screen content, the software has two characteristics:

It only takes up very little CPU resources and does not affect the operation of other programs; The compression ratio is very high, and it takes up little disk space. The automatic text index generation system can automatically generate text indexes according to the contents of teachers' PPT documents and Word documents. Text index brings great convenience for students to play courseware. However, similar software can't automatically generate text index when recording, so it can only add index later, which brings great workload to teachers.

Courseware editing

After recording the courseware, you can cut the courseware at will, delete the useless parts, and cut the video and lecture notes synchronously. You can also splice multiple courseware to realize the function of adding a title and a title.

After the courseware recorded by network courseware on demand is published to the resource website, it is not necessary to install other client software, but only use the Internet Explorer browser to order courseware.

Audio-visual monitoring function provides audio-visual preview and monitoring function before and during courseware recording, which ensures the recording effect of courseware and avoids the phenomenon of "mute courseware".

The courseware generated by diversified courseware modes can be three-screen mode, single-screen movie mode, and files of both modes can be generated at the same time. Among them, the pictures in the single-screen movie mode include the teacher's explanation, the teacher's blackboard writing, the computer teaching courseware used by the teacher synchronously, the interaction between the teacher and the students, the students' answers, the students' operation exercises, etc., which realizes the picture-in-picture mode.

Generate courseware file format The video part of the courseware is in ASF format, and the screen part is in ASF or VGA format. The advantage of using ASF format is that you don't need to install any client software and plug-ins when you order, and the advantage of using VGA format is that the courseware is small and the picture quality is not lost.

Automatically adding titles and trailers can automatically generate titles and trailers of video, single-screen mode can realize picture-in-picture mode, and text or graphic logo can be added in the upper left corner of video.

Rich courseware style templates After recording the courseware, you can choose the appearance style template of the courseware according to your own preferences.

The operation is extremely simple.

There is no requirement for the teaching teacher, and the teaching teacher does not need to change the previous teaching habits; For audio-visual teachers, only three mouse clicks are needed to generate courseware; The whole system is easy to operate and is very suitable for the education industry.
