Description

Teaching wireless recording and broadcasting system

Technical Field

The utility model relates to a teaching recorded broadcast technical field, in particular to wireless recorded broadcast system of teaching.

Background

The recording and playing system integrates and synchronously records video and audio recorded on site and image signals (including computers, video exhibition stands and the like) of electronic equipment to generate a standardized streaming media file for external live broadcasting, storage, later editing and on-demand playing. The recording and broadcasting system and the teaching of the school are integrated, a camera is installed in a classroom of the school, collected signals of competitive courses, important meetings and the like are recorded into a computer hard disk in a multi-azimuth mode through the camera, and students or teachers can watch video files from different camera viewing angles. Meanwhile, the information sources on the network can be sorted and uploaded, and the purpose of fully utilizing the network learning resources is achieved. The teaching and recording and broadcasting system is organically combined, the technology in the teaching and recording and broadcasting system and the requirements of all links are discussed, and therefore the teaching and recording and broadcasting system is formed.

In the recording and broadcasting process of the current classroom teaching, the problems that the camera captures images in place and the adjustment is delayed are easily caused by the problems of operators. For sound collection, the overall sound collection effect is not good.

Disclosure of Invention
