Problems solved by technology

[0005] The purpose of the present invention is to provide a video acquisition device, a video acquisition system and a live broadcast method for remote teaching, which solves the problem of the live broadcast system in the prior art. The hardware equipment is not optimized for the teaching system, and the live lecture cannot be displayed in an all-round way. The real situation in the room cannot meet the listening needs of student members of different levels, and it is not suitable for the classroom teaching environment. When the network signal is not good, the video signal is blurred, stuck or the live broadcast is interrupted; at the same time, the network signal is stolen. serious

Abstract

The invention provides a video acquisition device and system used for remote teaching, and a direct broadcast method. The device includes a first camera, a second camera, a third camera, a fourth camera, a first A / D chip, a second A / D chip, a third A / D chip, a fourth A / D chip, a first encoder, a second encoder, a third encoder, a fourth encoder, an FPGA chip and a tetrahedral installation rack; and the first camera, the second camera, the third camera and the fourth camera are separately arranged in the center of each of the four faces of the tetrahedral installation rack. The video acquisition device and system used for remote teaching, and the direct broadcast method collect different video data through the four cameras, obtain the video data with different definition after video conversion, and send the video data with different definition to different users, so that video playing can be safer and more fluent, and user demands can be met.

Description

technical field [0001] The invention relates to the technical field of live video broadcasting, in particular to a video acquisition device, a video acquisition system and a live broadcast method for remote teaching. Background technique [0002] The business education system is becoming more and more popular. A remote teaching live broadcast system that has emerged in recent years can effectively solve the problems of traditional education such as regionality and teachers. It can take advantage of the network's advantage of not being disseminated by regions to integrate the best educational resources and original intellectual property rights. Creators can solve problems such as the regional restrictions of traditional classroom teaching, the randomness of recorded and broadcast lectures, and the high cost of one-on-one online teaching. [0003] In the live broadcast system in the prior art, the hardware equipment is not optimized for the teaching system, and it cannot fully...
