Abstract

The invention discloses a browser based screen frame transmission method. The method comprises the steps that a display frame in the present moment is captured; data of the captured display frame is transmitted to a local browser; on the basis of the local browser, the data of the display frame is sent to a server; and via the data, the server is triggered to send the frame of the display frame toa subscribed receiving-end device via a multimedia channel, and the receiving-end device which receives the data is triggered to render and display the data via a browser. The multimedia channel includes a communication line of UDP based on WebRTC. An embodiment of the invention further provides a screen frame transmission device and system and a storage medium. Thus, screen frame transmission can be more instant and smoother, and the upper limit of participators that can be supported in screen frame transmission can be increased.

Description

technical field [0001] The present invention relates to the field of screen sharing, in particular to a screen image transmission method, device, server, system and storage medium. Background technique [0002] Screen sharing is of high application value in modern work, and it is also widely used in modern teaching. For example, in the participation of the same activity, such as a meeting or a class, a participant wants to share the screen image being played by his source device with other participants, such as the speaker at the meeting will share the displayed content to the audience Play on the devices of the participants, or the teacher shares the lecture content on the devices of the students for display, so that multiple participants in the event can watch the same display content on their own devices. [0003] In the implementation of screen sharing, screen image transmission is the core technology. In the prior art, in order to realize the transmission of the scree...
