Frame switching method, device and system

Abstract

The embodiment of the invention discloses a frame switching method, and aims to solve the problems that an existing broadcasting switching method easily has broadcasting misjudgement and inaccurate broadcasting switching timing; the method comprises the following steps: detecting a video frame in a first assigned area has a first user, and detecting the audio signals in the first assigned area comprise the first user voices, then a first switching signal is formed; detecting a video frame in a second assigned area has a second user, and detecting the audio signals in the second assigned area comprise the second user voices, then a second switching signal is formed; switching the main frame of the display equipment according to the first switching signal and / or the second switching signal and preset main frame switching rules. The embodiment also provides a frame switching device and a recording and broadcasting system.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a screen switching method, device and system. Background technique [0002] When using the recording and broadcasting system, while people are pursuing higher video quality, a smoother video experience of role switching during video playback is often a potential quality requirement of people. [0003] At present, the recording and broadcasting systems on the market generally adopt the method of manual broadcasting, or the method of automatic broadcasting switching by dividing specific identification areas and judging the height of users. For example, in the application scene of teaching, when using the recording and broadcasting system, there are generally two camera bolts, the first bolt is installed at the rear of the classroom, and the camera is taken from the rear of the classroom. The main shooting area is the entire podium, and the shooting The object is t...

Problems solved by technology

[0004] The existing automatic guide switching method not only needs to pre-set a specific area in the panoramic screen (such as setting the teacher's area in the teacher's panoramic screen), but also judges whether there is a corresponding action by the user in the screen through the frame difference method. Misjudgments are often prone to occur. For example, when a student raises his hand, it is easy to be misjudged as the student standing up

It can be seen that the existing technology is prone to the problems of misjudgment of the director and inaccurate switching timing of the director
