A method for making electronic files for electronic classrooms based on electronic blackboards

Abstract

The invention relates to a method for making an electronic record for an electronic class based on an electronic blackboard. The method comprises the following steps: automatically acquiring and storing all call-in content through an electronic record grasping module, starting to display an electronic record, and recording the electronic record use or play time in sequence according to the play time; synchronously recording electronic writing on a touch display panel and forming an electronic writing source file in real time according to the time sequence through an electronic writing capturing module; synchronously recording teacher instruction sound and forming a sound source file in real time according to the time sequence through a microphone; after receiving a user combination instruction, automatically combining the electronic file, the electronic writing source file and the sound source file according to the time sequence so as to form an electronic record through an electronic file combining module. By adopting the method, the teacher instruction habit does not need to be changed, a play vector file, a writing vector file and the sound source file can be automatically combined according to the time sequence so as to obtain an optimal electronic record in a video encoding manner by using the electronic blackboard in a common class.

Description

technical field [0001] The present invention relates to a method for making electronic teaching files used in electronic classrooms, in particular to a method for making electronic files for electronic classrooms based on electronic blackboards, through which the teaching content of teachers using electronic blackboards can be transferred to online Electronic files used in electronic classrooms. Background technique [0002] With the rapid development of network technology, electronic classroom or online education has gained more and more development applications. The content of electronic classrooms or online education is mostly electronic files made of offline teaching content, so how to make offline teaching content into electronic files so as to upload them to the network to form electronic classrooms is a very important issue. The method currently used in the market is mainly to record the teaching content and displayed electronic documents (including office series doc...

Problems solved by technology

The disadvantages of this method include: 1) The cost of recording and broadcasting classrooms is high, and only schools with sufficient funds can afford them; Teachers seldom use it actively, and it is generally used in public lectures or teaching exchanges; 3) This method takes up a lot of resource content, and the high-quality ones reach 20-100M storage capacity. Due to the extremely high bandwidth occupation, it is not conducive to remote lectures or students watching at home Reading; 4) Since the image content is video recording, the quality is not good, especially the display of text will produce blurred edges, unclear borders, and rough lines, resulting in poor viewing clarity
