Description

A self-service multifunctional micro-lecture recording system

technical field

The utility model relates to a teaching appliance, in particular to a self-service multifunctional micro-lesson recording system.

Background technique

As a kind of electronic teaching courseware commonly used in current school teaching, micro-course refers to a micro-network courseware composed of short lecture videos with multiple teaching links. Its main features are video and simplicity.

At present, in schools, the recording methods of micro-lectures usually involve a lot of expensive and complicated special equipment, including studios, high-definition cameras, background curtains and lighting, and corresponding video editing systems. These special equipment are not only expensive, but also occupy a fixed site and space; the hardware equipment involved is of various types, the cost of use and maintenance is high, and the operation method is complicated, so professionals must be required to operate and use it. From a practical point of view, this kind of equipment is far from being mastered and used by teachers of ordinary subjects, and it is impossible to popularize it. Therefore, currently in schools, the production of micro-lessons is mainly filmed and produced by professional audio-visual teachers for teachers. This results in time-consuming and labor-intensive production process, high design cost and long production cycle. However, the micro-lectures produced in this mode have high cost and small quantity, and the teaching effect is not ideal. The main reason is that due to the complex technology and difficult operation of the production process, subject teachers can only participate passively, lacking initiative and enthusiasm. Especially when recording video in front of a professional videographer in the studio, most teachers showed a strong sense of nervousness and discomfort, and the video effect was poor. In addition, because the production process involves too many technical factors, it is difficult for subject teachers to fully implement their own teaching design ideas into the production, resulting in the separation of the two links of technical production and teaching application.

Obviously, the above-mentioned factors not only limit the scope of application of micro-lectures in teaching, but also affect the quality of micro-lecture production-because the micro-lectures designed by audio-visual educators often fail to meet the actual teaching needs of subject teachers, the actual effect not ideal.

detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

A kind of self-service multifunctional micro-class recording system as shown in Figure 1 and Figure 2, comprises computer 1, video acquisition device 2, monitor display device 3 and curtain wall 4, and described computer 1 is fixed on computer desk by docking station 5 6, the video capture device 2 is connected to the external interface of the docking station 5, the monitoring display device 3 is connected to the video capture device 2, and the curtain wall 4 and the computer table 6 are provided with auxiliary lighting equipment 7.

Wherein, the video collection device 2 includes a high-sensitivity directional microphone and a miniature digital camera; the connection between the monitoring display device 3 and the video collection device 2 can be a kind of HDMI cable or a Wi-Fi signal; The computer desk 6 is liftable and is provided with universal casters at the bottom of the computer desk 6; a display is also connected to the external interface of the docking station 5; the curtain wall 4 includes a metal bracket 41 and is installed on the metal bracket 41. On the screen 42, the metal bracket 41 is foldable.

A kind of self-service multifunctional micro-class recording system mentioned in the above specific embodiments, when it is recording a specific micro-class, the auxiliary lighting equipment 7 is fixed on the opened curtain 42 and the metal support 41, and placed on the teacher's side Behind the back, the computer 1 , the video capture device 2 and the display are connected to each other through various interfaces provided by the docking station 5 , which can transmit computer video signals to the display in real time.
