Audio/video two-in-one collecting device and cloud recording and playing method applied to video teaching

Abstract

The invention discloses an audio / video two-in-one collecting device. The device comprises a recording and playing camera unit for collecting recorded sound data and image data of recorded objects, thus forming teaching courseware; a switch unit for receiving the teaching courseware of the recording and playing camera unit and sending the received teaching courseware to cloud servers by a network; and cloud server units for processing the received teaching courseware, wherein the recording and playing camera unit is in communication connection with the switch unit by the network. The switch unit is in communication connection with the cloud server units by the network. The device and the method have the advantages that wireless integration between the switch and the servers can be finished only by one high integrated recording and playing camera unit, the video teaching cost is greatly reduced, the teaching load is mitigated, and live broadcast and video-on-demand can be carried out to the video teaching contents only by carrying out the simple and high integrated recording and playing camera unit in an ordinary classroom.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of network equipment, is a network multimedia device, and in particular relates to an audio and video two-in-one collection device and a cloud recording and broadcasting method for video teaching. Background technique [0002] With the transformation of educational thoughts and concepts, the application of science and technology in the field of education is becoming more and more popular. The current automatic recording and broadcasting tracking device is the most critical device for the application of online education, which involves more equipment and mode, and its control principles include the following three types: infrared tracking technology, image recognition analysis technology and ultrasonic tracking switching technology. [0003] When the infrared tracking technology is used to record and broadcast the picture, the camera picture will also move when the person or object b...

Problems solved by technology

[0003] When the infrared tracking technology is used to record and broadcast the picture, the camera picture will also move when the person or object being photographed moves, which will cause the whole picture to shake continuously, which will bring eye fatigue to the people watching the recorded and broadcast video; adopt image recognition and analysis technology , it needs to use at least three positioning cameras when collecting images, and there are a lot of auxiliary equipment, which requires complicated equipment installation and circuit wiring, which is difficult to achieve in conventional classrooms; while using ultrasonic tracking technology, due to the uncertainty of the sound source , will produce more abnormal video images, which are not suitable for large and small classrooms, and the potential harm of ultrasonic technology has been controversial. Therefore, the automatic recording and broadcasting tracking devices using the above three technologies are all It has its limitations and cannot be applied to existing complex recording and broadcasting hairstyles

[0004] Therefore, how to realize the current decentralized equipment, high cost and various types of automatic tracking recording and broadcasting devices that are difficult to install
