Embodiment Construction

[0052] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0053] The invention provides an audio-visual synchronous linkage method for online learning. The specific technical content of each part is as follows:

[0054] 1. Synchronous linkage method

[0055] The execution process of the audio-visual synchronous linkage method can be expressed as figure 1 shown. to combine figure 1 The labels in are described in detail below.

[0056] (1) Timing trigger mechanism of audio and video

[0057] During the playback of audio and video, an asynchronous mechanism is used to trigger events. Such as figure 1 In part ①, in the asynchronous thread, through a preset small polling time t, regular polling checks whether there is an event that meets the conditions and triggers it.

[0058] (2) Synchronization time point check

[0059] The synchronization time point is a preset and stored array. The value of the time point is in sec...

Abstract

The invention discloses an audio and video synchronized driving method used for online learning and relates to computer online education. The method comprises the first step of timing triggering of audio and video, the second step of checking of a synchronization time point, the third step of mapping and triggering of the synchronization time point and a teaching material, the fourth step of mapping and triggering of the synchronization time point and a note, the fifth step of mapping and triggering of the synchronization time point and a sign, the sixth step of mapping and triggering of the synchronization time point and an outline, and the seventh step of synchronization of a non-audio-or-video entity. The scene of traditional course teaching is reproduced, so that the learning process is immersive; in addition, after the course teaching material is separated from the audio and video, a learner can conveniently learn the note and mark key points / difficulties / doubtful points / and the like, and the note and the sign are also synchronously linked with the audio and video.

Description

technical field [0001] The invention relates to the technical field of computer online education, in particular to an audio-visual synchronous linkage method for online learning. Background technique [0002] Online learning can transcend the constraints of time and space, listen to excellent courses from first-class lecturers, and quickly master the knowledge and skills you need. This is a development trend of contemporary learning forms and a trend of modern distance learning methods. [0003] Through online learning, learners can acquire the knowledge or skills they need at home, in the workplace, or even on the road, without being limited by the traditional face-to-face education methods that require centralized locations, fixed time, etc. provide great convenience to people. [0004] The currently commonly used online learning methods are mainly audio and video, and learners learn online by watching audio and video. The content of learning is usually placed in audio a...
