Description
Technical Field
The invention relates to the field of live-broadcast lecture, in particular to a live-broadcast lecture system and a live-broadcast lecture method for online and offline fusion training of enterprises.
Background
Live teaching system is a system that carries out video live teaching, the sudden attack of following the epidemic situation, live trade rapid development, more and more enterprises use the live to carry out staff training, compare live low-cost and can high-efficient a large amount of staff of covering of off-line class journey live, but live and traditional off-line teaching individual have the thousand years to training effect, off-line face-to-face training, the teacher can effectively supervise the student, on-line live broadcast, training data can be preserved, the teacher easily carries out the result of training and rewrites, therefore, more and more lecturers hope to use the on-line and off-line to fuse the training, come full play the advantage separately of two kinds of training mode, traditional on-line and off-line fuses the training mode, the separation of difference is gone on-line in the teaching, off-line goes on, let on-line teaching performance digitization and the advantage that covers the region fast, let off-line teaching performance traditional learning effect, at present, the mode of supervising generally is that enterprise lecturers will be fit for on-line understanding the content that the link will be suitable for on-line by oneself through live teaching, and part is suitable for learning or the operation of accomplishing after-line completion. With the wide application of the two-teacher classroom mode in the K12 field, many enterprises apply the two-teacher classroom mode to online and offline teaching scenes, for example, headquarters train teachers to live broadcast on line, and local students concentrate on watching through a large screen of an offline classroom, and a field also has an effect of assisting the teachers to supervise and answer questions, and with the continuous development of science and technology, the manufacturing process requirements of people on a live broadcast teaching system are higher and higher.
The prior teaching system has certain disadvantages in use, firstly, most of the prior teaching systems give lessons off line and can not well cover a large number of staff, the training of staff is difficult, the use of people is not facilitated, the students cannot be effectively supervised well, enterprises hope that all online and offline teaching interaction links can be kept online while online and offline fusion training is realized, but because of the technical limitation, partial offline interactive data is difficult to capture, so that the data is lost in offline nodes, the problem can be solved to a great extent by a classroom of two teachers, the lecturer interacts with the student through a remote lecture-listening display screen, and the data is stored, however, the hardware construction mode is complex and has higher price, for example, the mode with the lowest cost can be used, for example, a lecturer can use one computer to connect a classroom field display screen, synchronously display the PPT to a field large screen to give lectures to field students, and in addition, use another computer to enter a lecturer lecture end to synchronously broadcast field pictures to remote students in a live way, which means that, under the condition that a live lecturer controls a live large screen, the PPT at the live lecturer end needs to be synchronized by another auxiliary lecturer along with the page turning progress of the live large screen PPT, and the operation may cause that live content and live content cannot be synchronized in real time, other defects are that the shared screen part of a lecturer cannot be displayed in live broadcasting, a field student enters into the live broadcasting to cause interference on a computer for live broadcasting lecture, interaction cannot be participated, the whole step increases a use threshold for training the lecturer, certain adverse influence is brought to the use process of people, and therefore the live broadcasting lecture teaching system and the method for online and offline fusion training of enterprises are provided.
