Embodiment Construction

[0026] Such as figure 1 As shown, the present invention is a dynamic adaptive system for transmitting high-quality online course videos, which consists of a server and a client. The server is responsible for video receiving content identification and classified storage, mainly deploying video receiving module, video segmentation module, video segmentation classification module, and video transcoding storage module; the client is oriented to students, providing students with content-based dynamic To adapt to video streaming, mainly deploy video viewing module and dynamic bit rate adjustment module.

[0027] The overall implementation process of the system is as follows:

[0028] (1) Receive the video sent by the teacher, record the receiving time and store it in the server, and assign transcoding tasks according to the teacher's video sending time;

[0029] (2) segment the video sent by the teacher according to the color feature, and obtain video segments with different conte...

Abstract

The invention relates to a dynamic adaptive stream system for transmitting high-quality online course videos. The dynamic adaptive streaming system is composed of a server and a client; the server is used responsible for identification and classified storage work of receiving contents of a video and is mainly deployed with a video receiving module, a video division module, a video classification module and a video transcoding storage module; and the client is oriented to students for providing dynamic adaptive video stream based on the contents to the students and is mainly deployed with a video watching module, and a code rate adjustment module. The dynamic adaptive stream system provided by the invention effectively improves the utilization rate of the bandwidth and the user experience, and can effectively transmit the online course videos.

Description

technical field [0001] The invention relates to a dynamic self-adaptive streaming system and method for transmitting high-quality online course videos, belonging to the field of computer network applications and computer multimedia fields. Background technique [0002] Currently, Massive Open Online Courses have become the most popular channel for knowledge acquisition. Web-based teaching allows teachers around the world to present their courses to anyone interested in learning; students can also take courses at a convenient location. This technology enables users to efficiently share or obtain the most cutting-edge information, making the learning mode innovative. For online learning platforms, due to the often changing network environment, it is very important to use adaptive video streaming to transmit high-quality Massive Open Online Courses (Massive Open Online Course, MOOC) courses. Although Dynamic Adaptive Streaming (DASH) has been widely adopted in streaming media...
