为了更清楚地说明本发明，下面结合优选实施例和附图对本发明做进一步的说明。附图中相似的部件以相同的附图标记进行表示。本领域技术人员应当理解，下面所具体描述的内容是说明性的而非限制性的，不应以此限制本发明的保护范围。In order to explain the present invention more clearly, the present invention will be further described in conjunction with the preferred embodiments and the accompanying drawings. Similar components in the drawings are denoted by the same reference numerals. It should be understood by those skilled in the art that the following detailed description is intended to be illustrative and not restrictive.

在线教育是通过应用信息科技和互联网技术进行内容传播和快速学习的方法。随着互联网技术的发展，远程实时的在线授课，老师与学生之间可以实时的互动，良好的用户体验使在线教育成为越来越普通的教育形式。Online education is a method of content dissemination and rapid learning through the application of information technology and internet technology. With the development of Internet technology, remote real-time online teaching, real-time interaction between teachers and students, a good user experience makes online education an increasingly common form of education.

为了便于用户及在线教育机构对在线授课的课程情况进行回顾和评价，通常会保存网络教学的相关视频和课件等文件并向用户或在线教育机构相关部门提供回放功能，对于幼儿教育，也可使家长可以随时随地观看老师和学生的上课情况。In order to facilitate users and online educational institutions to review and evaluate the courses taught online, it usually saves relevant videos and courseware files for online teaching and provides playback functions to users or relevant departments of online educational institutions. Parents can watch the classes of teachers and students anytime, anywhere.

但是，目前的网络课程结束后，***需保存老师和学生的上课音频、视频和上课的课件等多个文件，老师和学生的音频和视频单独保存，且根据老师端和学生端的设备不同，保存的音视频的格式可能不统一(例如视频可以是FLV或MP4等格式)，在向用户展示回放页面时，需要将老师和学生的音视频和课件依次加载至回放页面，回放页面对于多种格式的视频文件，大多不支持视频的直接加载，需要依赖于第三方软件(例如FLASH)加载播放教学视频，一方面，采用第三方软件播放视频会导致视频加载慢，另一方面，第三方软件的升级会对用户使用造成不便，也可能会导致视频文件无法播放。而对于音视频的获取，通常会采用CDN边缘节点拉取音视频数据，而CDN等缓存***的升级也可能导致音视频文件在传输过程中的损坏，导致音视频无法播放。此外，回放页面需要加载音视频以及课件等多个文件并后端控制多个文件的运行，在用户进行拖拽或跳转时处理逻辑复杂，以上的各种问题会导致回放页面出现进入和拖动速度慢、卡顿感较强，更甚至会导致回放页面的不可用，用户体验效果差。However, after the current online course is over, the system needs to save multiple files such as audio and video of the teacher and students, and the courseware of the class. The audio and video of the teacher and the student are saved separately, and are saved according to the equipment of the teacher and the student. The format of audio and video may not be uniform (for example, the video may be in FLV or MP4 format). When displaying the playback page to the user, the audio and video and the courseware of the teacher and the student need to be sequentially loaded to the playback page, and the playback page is for multiple formats. Most of the video files do not support the direct loading of video. It is necessary to rely on third-party software (such as FLASH) to load and play the teaching video. On the one hand, playing video with third-party software will cause the video to load slowly. On the other hand, the third-party software The upgrade may be inconvenient for the user to use, and may also cause the video file to be unplayable. For the acquisition of audio and video, CDN edge nodes are usually used to pull audio and video data, and the upgrade of the cache system such as CDN may also cause damage to audio and video files during transmission, resulting in inability to play audio and video. In addition, the playback page needs to load multiple files such as audio and video and courseware and control the running of multiple files in the back end. The processing logic is complicated when the user drags or jumps. The above various problems will cause the playback page to enter and drag. The moving speed is slow, the sensation is strong, and even the playback page is unavailable, and the user experience is poor.
