Problems solved by technology
[0003] The difference between the teaching recording and broadcasting system and the conventional recording and broadcasting system is that in the process of interaction between teachers and students, there are often scenes of self-study by students. However, the existing recording and broadcasting systems have relatively simple recording strategies, and usually only set video The total duration cannot be automatically paused and started according to the specific scene where the teacher suspends the lecture and the students study by themselves during the recording process, resulting in a large amount of video data obtained after the recording ends, which in turn brings a lot of inconvenience to video storage and transmission; 45 minutes of class (recording 1080P resolution video), 8 classes per day as an example, the amount of video data per day is: 6Mbit / s÷8÷1024×60sec / min×45min×8=1.5G

The invention discloses an intelligent recording and broadcasting method and system. The intelligent recording and broadcasting method comprises steps of monitoring audio frequency input and input signals coming from an input device after a recording process starts, if at some moment, the audio frequency input and the input signals of any input device are not detected, starting timing, if audio frequency input or input signal from the input device are detected in the timing process, zeroing out the timing and continuing to monitor, and if the timing reaches the threshold duration, pausing the recording process, and restarting a recording process when audio frequency input and the input signal from the input device are detected. The intelligent recording and broadcasting method and system can automatically suspend recording when not detecting the teaching activity during a certain time, and restart the recording after the teaching activity is detected, which reaches the effect of saving the storage space and optimizing the video content.
Description
technical field [0001] The invention relates to the field of teaching image recording and broadcasting, in particular to an intelligent recording and broadcasting method and system capable of filtering redundant time in the teaching process. Background technique [0002] The recording and broadcasting system is to integrate and record the video, audio, and image signals of electronic equipment (including computers, video booths, etc.) recorded on the spot, and generate standardized streaming media files for external live broadcast, storage, post-editing, and on-demand broadcasting. Integrate the recording and broadcasting system with school teaching, install cameras in school classrooms, and record signals collected from high-quality courses and important meetings to computer hard drives in multiple directions through cameras. Students or teachers can watch video files from different camera perspectives. At the same time, it is also possible to organize and upload online inf...
