Description of the Invention: [Technical Field of the Invention] The present invention relates to a video teaching method, and more particularly to an instant interactive video teaching method. [Prior Art] General video conferencing, video teaching, etc. refers to the method of teaching and communicating between the presenter and the audience through images; that is, in the speaker's field, there is a photographic device to shoot the speaker's speech or teaching content. And through the computer conversion and then transmitted to the audience 'in the audience, there is a computer capable of playing video' and the computer system of the presenter and the listener is connected to each other through a servo device. Therefore, regardless of the location of the presenter and the listener, the presenter As long as the listener connects to the servo device through the computer, the viewer can instantly capture the image of the presenter's and instantly play it to the audience, so that the listener can also watch the speaker's speech or teaching at the far end. In addition to the instant video broadcast, the video can be recorded as an image file, allowing the listener to view the video by simply clicking on the image file to be viewed. For example, if the presenter is a lecturer and the audience is a student, in the general video teaching, whether the student is watching the live video of the lecturer or watching the recorded video mark, the student is unilaterally watching the lecturer in front of the computer. For the lecturer, the lecturer cannot know the student's learning status in the process of teaching. For the student, the student can't immediately respond to the question: it is an immediate response to the lecturer's class content. Therefore, the lecturer cannot understand the learning situation of each student, and does not adjust the teaching content to affect the teaching efficiency. SUMMARY 201243788 SUMMARY OF THE INVENTION Accordingly, it is a primary object of the present invention to provide an interactive video teaching method that enables a presenter and a listener to maintain high interaction during video playback so that the listener can immediately send a response message for the presenter to immediately grasp the audience. The echoes to enhance the interactive effect. In order to achieve the above, the technical means adopted by the present invention is that the interactive video teaching method includes an instant mode, and the instant mode includes the following steps: capturing a video from a main terminal and storing it, and generating at the main terminal A message feedback display interface; determining whether a rebroadcast request is received from more than one listener; if receiving a broadcast request, the video is immediately transmitted to the listener, and an instant feedback interface is generated on the listener for feedback. The message is received and received by the listener; and the received sync mark message is synchronously updated to the message feedback display interface of the presenter and the instant feedback interface of the listener. Through the pre-existing instant mode, while the presenter is speaking or teaching, the audience can immediately send out the markup message on the audience and synchronize it at the main speaker, so that the presenter can immediately grasp the reaction of each listener, and then accelerate and slow down accordingly. The speech or teaching content, in order to achieve the purpose of the speaker and listen to the movement. Another object of the present invention is to enable the interactive video teaching method to include a non-time mode. The non-instant mode includes the following steps: providing one or more video files; accepting one or more listener requests; and transmitting a video file. To the listening end, and generate a 4 201243788 interface in the listener's display of the historical feedback information of the video by the feedback message statistical interface for the listener to respond to the feedback message; receiving the synchronization mark message sent from the listener; Save the sync mark message and update the feedback message statistics interface. Through the non-instant mode, the listener can refer to the historical feedback message to make corresponding actions when viewing the video. For example, refer to the historical feedback message to select the video playback progress, and in this mode, the listener is still watching the video while still listening to the video. A sync mark message can be sent, and the presenter can understand the reaction of the listener to view the video by synchronizing the mark message. [Embodiment] Please refer to the preferred embodiment of the present invention shown in FIG. 1 , which mainly provides a teaching method for executing a media-to-media (4) server 1Q, and the media transmitter 1 and a terminal 20 can be a computer.
