The invention discloses a
video transmission method of an embedded remote teaching experiment
system. The
video transmission method comprises the following steps: 1, establishing a
DASH live broadcast
server cluster; 2, establishing a
DASH on-demand
server cluster; 3, preparing a video, and
transcoding and
slicing the recorded video file; 4, establishing a
reverse proxy server; 5, establishing a Node.js operation environment for operating a
signal server code; 6, establishing a
Web server and a
Sip server for protocol conversion to realize
remote communication between the
client and the embedded equipment; 7, playing on-demand and live videos through a
DASH transmission protocol by the
client; 8, setting up an access for establishing a
WebRTC communication
signal server and a
WEB server and used for realizing through the Node.js operation environment and used for achieving the
signal interaction function of
WebRTC communication and the access of a video playing page,and finally realizing the function that two users share the desktop remotely in real time through a browser. Therefore, students share the desktop content to a teacher browser page. The function of online
question answering of the teacher is realized through
voice communication.
