Problems solved by technology

[0002] At present, standard recording and broadcasting classrooms are usually expensive and need to be equipped with multiple photography and recording equipment. After collecting the recorded and broadcasting content, the data needs to be edited and synthesized. The equipment used for synthesis is often expensive, and each school usually only has a few Demonstration lessons can be held in recording classrooms, which is not conducive to the large-scale implementation of recording and broadcasting, and is not conducive to the sharing and utilization of high-quality educational resources
Reduce the cost of recording and broadcasting equipment, and realize the widespread implementation of recording and broadcasting. At present, no better solution has been proposed

Abstract

The invention provides a lightweight recorded broadcast system, apparatus and system, and relates to the technical field of recorded broadcast. The method comprises the following steps: obtaining first video information, audio information and screen display information of a scene; identifying an action of a target object in the first video information; comparing the action with action data in an action library to determine a target action matching the action; adjusting the focal length and direction of a camera according to the target action to generate a zoomed or multi-view-angle second video information; and performing synchronous processing on the first video information, the second video information, the audio information and the screen display information to generate a recorded broadcast file. According to the lightweight recorded broadcast system, apparatus and system provided by the invention, the multi-focal length and multi-direction record of live video information can be achieved just by using one camera, thereby reducing the number of used camera devices, relieving the synthesis and production difficulty of the subsequent recorded broadcast file, reducing the implementation cost of the recorded broadcast file, and facilitating the sharing and use of high-quality education resources.

Description

technical field [0001] The invention relates to the technical field of recording and broadcasting, in particular to a lightweight recording and broadcasting method, device and system. Background technique [0002] At present, standard recording and broadcasting classrooms are usually expensive and need to be equipped with multiple photography and recording equipment. After collecting the recorded and broadcasting content, the data needs to be edited and synthesized. The equipment used for synthesis is often expensive, and each school usually only has a few Demonstration lessons can be held in recording classrooms, which is not conducive to the large-scale implementation of recording and broadcasting, and is not conducive to the sharing and utilization of high-quality educational resources. To reduce the cost of recording and broadcasting equipment and realize the widespread implementation of recording and broadcasting, no better solution has been proposed yet. Contents of ...
