Method, device and system for cloud projection

Abstract

The embodiment of the invention provides a cloud projection method, device and system. The method comprises the following steps: recording image data of a screen of a projection sending end; collecting audio data of the projection sending end; and sending the image data and the audio data to a projection display end through WebRTC standard, thereby enabling the projection display end to project the image data and play the audio data. The projection sending end and the projection display end transmit the image data and the audio data in a unified way through the WebRTC standard without utilizing a data adaption line of the corresponding protocol, the point-to-point projection way is realized, the thread deployment and the management difficulty can be lowered, and the simultaneous display ofthe image data and the audio data is realized, and the user experience is excellent.

Description

technical field [0001] The present invention relates to the technical field of information display, in particular to a cloud projection method, device and system. Background technique [0002] With the development of multimedia technology, the projection function has become an essential function for office meetings and life entertainment. Such as figure 1 As shown, the projection sending end equipment includes such as Notebook (notebook computer), Tablet PC (tablet computer), MobilePhone (smart phone), PC (desktop motor), DVD Player (digital versatile disc player), KTV (karaoke player) ) and Game Console (game console), etc., are connected to projection display end devices (such as projectors) through data adapter cables to realize projection display. [0003] However, the inventor found in the process of realizing the present invention that the prior art has at least the following problems: [0004] With the diversification of projection sending end devices, projection d...

AI Technical Summary

Problems solved by technology

[0004] With the diversification of projection sending end devices, projection display end devices need to communicate under multiple data protocols in order to receive data signals from different types of projection sending end devices, but the communication ports of different types of data protocols are different, including: VGA (Video Graphics Array, Video Graphics Array), DVI (Digital Visual Interface, Digital Video Interface), HDMI (High Definition Multimedia Interface, High Definition Multimedia Interface), USB (Universal Serial Bus, Universal Serial Bus), DP (Display Port , display interface) and other ports, so the projection display device needs to be equipped with various types of data adapter lines, which leads to complicated line deployment and increases the difficulty of line management
