Preferably, the teaching teacher can be determined by integrating the preset curriculum schedule and the local classroom recording data, and then the corresponding classroom audio data is extracted from the complete classroom recording data. The content corresponding to the classroom audio data is matched with the preset teaching keywords, and the content corresponding to the classroom audio data which is consistent in matching can be used as teaching content of the teaching teacher as the preset teaching keywords used by the teaching teacher in the class. And then, the main voiceprints in the matched consistent classroom audio data are used as the voiceprints of the teaching teacher, the voiceprints of the teaching teacher are subjected to noise removal and enhancement, other irrelevant voiceprints and environmental noise are weakened or removed on the basis of not influencing the voiceprints of the teaching teacher, and the clear classroom recording data are obtained by splicing with other data except the teaching content data. And then, referring to the step S204, the clear classroom recorded data is analyzed to obtain the corresponding classroom recorded video.

According to the embodiment, the teaching teacher and the classroom audio data corresponding to the complete classroom recording data are obtained, the preset teaching keywords are used for matching, and teaching content data of the teaching teacher are determined. And obtaining voiceprints of teaching teachers, carrying out clear processing on teaching content data to obtain clear classroom recording data, and then analyzing the clear classroom recording data to obtain corresponding classroom recorded broadcast videos. And after the explanation definition of teaching content data of the teaching teacher is improved, processing the clear classroom recorded data, and improving the transmission effect of the classroom recorded video finally obtained.

In some embodiments, the method may specifically further include: acquiring a preset heavy difficulty point course from a course database, and judging whether the course corresponding to the recorded data of the complete classroom is the preset heavy difficulty point course or not; if not, carrying out coding compression on the complete classroom recorded data;

correspondingly, the method for obtaining the voiceprint of the teaching teacher and performing the definition processing on the teaching content data corresponding to the voiceprint of the teaching teacher in the complete classroom recording data to obtain the definition classroom recording data specifically may include: if yes, the voiceprint of the teaching teacher is obtained, and the teaching content data corresponding to the voiceprint of the teaching teacher in the complete classroom recording data is subjected to clear processing, so that clear classroom recording data is obtained.

The course database can be preset in the video transmission server in advance and is used for storing the names and course contents of the preset heavy difficulty courses. The preset heavy difficulty course can be a course which is important to learn and review when the recording time corresponding to the data is recorded in the local classroom. In some implementations, the preset heavy difficulty course can be formulated according to the requirements of schools and countries, for example, some course contents are courses which are important to be examined in the examination process. In addition, if the recording time corresponding to the local classroom recording data is not the time period of the test and the examination, the course corresponding to the local classroom recording data and the associated course can be used as the preset heavy difficulty course. The preset heavy difficulty courses stored in the video transmission server may be updated according to the requirements of schools or countries.

The encoding compression can be a processing mode for adjusting the definition of the complete classroom recorded data, and when the complete classroom recorded data is encoded and compressed, the definition of the complete classroom recorded data can be reduced at the moment, and the occupied storage space is smaller.

Specifically, the name and the course content of the preset heavy difficulty course can be obtained from the course database, then the complete classroom recording data can be analyzed, and the corresponding course content is obtained to be matched with the course content of the preset heavy difficulty course. If the matching results are inconsistent, the course corresponding to the complete classroom recorded data is not a preset heavy difficulty course, and the complete classroom recorded data can be encoded and compressed at the moment; if the matching results are consistent, the course corresponding to the complete classroom recorded data is a preset heavy and difficult course, and at the moment, voiceprints of teaching teachers can be obtained, and the clear processing of the complete classroom recorded data is performed to obtain clear classroom processing data.

According to the embodiment, the preset heavy difficulty course can be obtained from the course database, and if the course corresponding to the complete classroom recorded data is judged not to be the preset heavy difficulty course, the complete classroom recorded data can be encoded and compressed, so that the storage space of the course recorded and broadcast video is saved.
