Novel recording and broadcasting equipment

Abstract

The invention discloses novel recording and broadcasting equipment. Comprising a video source interface module, a picture layout module, a video source conversion module, an audio input module, a control module, a recording module, a live broadcast output module, a display module and an audio output module, wherein the video source interface module is used for accessing original video signals acquired by more than two camera acquisition devices for different scenes and a PC signal. The picture layout module is used for defining a picture style and a display scale of a recorded video, wherein the picture style is a form of simultaneously displaying more than one video signal and a display position on a video picture; according to the display scale, more than one video signal and more than one PC signal are proportionally converted and displayed on the same recorded picture according to the size and the display style of the recorded picture. The video source conversion module is used for converting the original video signal accessed by the video source interface module; the novel recording and broadcasting equipment has the advantages that the video recording quality is improved, and the workload of video processing is reduced.

Description

technical field [0001] The invention relates to the technical field of recording and broadcasting, in particular to a novel recording and broadcasting device. Background technique [0002] The development of the online education industry needs to convert more classroom teaching into video resources. Classroom teaching usually needs to collect video sources and VGA / DVI / HDMI signals of multiple scenes, and synthesize them into a complete video during post-editing or recording. The technical scheme of post-editing and synthesis consumes a lot of manpower and time. The technical scheme of recording process synthesis is adopted, generally using artificial guide synthesis in the background, and automatic scene tracking and switching based on image recognition, infrared detection and other methods to realize the synthesis of recorded video. For example, the authorized announcement number: CN103177615B proposes a recording and broadcasting system based on cloud computing technolog...

AI Technical Summary

Problems solved by technology

If manual broadcasting in the background is used, the director needs to be familiar with the teaching content in advance and cooperate with the lecturer tacitly, which requires additional manpower input and increases the difficulty of recording

If image recognition, infrared detection and other methods are used to automatically track and switch scenes, it often results in a large number of invalid switches and many waste shots.
