Problems solved by technology

In this way, on the one hand, the more common situation for users to use the WiFi Display function is to project document content to the large screen of the receiving device for browsing; on the other hand, projecting the screen interface to the receiving device in real time requires a large amount of mobile terminal equipment. resources, and sending a large amount of data in real time will have an impact on the power consumption and system memory of the mobile terminal device, which will cause slow data transmission or freeze, and bring a bad experience to users

Embodiment 1

[0199] Figure 8 It is an interactive flowchart of the document projection method provided by another embodiment of the present invention. Such as Figure 8 As shown, the document projection method in this embodiment includes:

[0200] Step 801, mobile terminal A and mobile terminal B establish a wireless display WiFi Display connection channel;

[0201] Step 802, mobile terminal A sends a WiFiDisplay media data stream to mobile terminal B through the WiFi Display connection channel for screen projection;

[0202] Both the mobile terminal A and the mobile terminal B support the WiFi Display (WFD) screen projection function. The WiFi Display screen projection function refers to projecting the interface and status of mobile terminal A (also known as source device or projection device) to mobile terminal B (also known as receiving device Sink device) in a wireless manner, and mobile terminal B The mobile terminal A can be operated wirelessly.

[0203] Step 803, the mobile te...

Abstract

The invention discloses a document projection method, terminal equipment and system. The document projection method is applied to the first terminal equipment, and comprises the following steps: establishing a wireless display WiFi Display connection channel with the second terminal equipment, and sending the WiFi Display media data stream to the second terminal equipment through the established WiFi Display connection channel so as to perform screen projection; after starting a document projection mode and opening the document, stopping sending the WiFi Display media data stream to the second terminal equipment through the WiFi Display connection channel; and sending the opened document to the second terminal equipment through a first connection channel so as to perform the document projection, wherein the first connection channel is the WiFi Display connection channel, or other wireless connection channel. By use of the technical scheme disclosed by the invention, the screen projection is stopped after the document projection mode is started and the document is opened, the media data transmission is reduced, only the document projection is performed, and the user experience is improved.

Description

technical field [0001] The present invention relates to but not limited to WiFi Display technology, especially a document projection method, terminal equipment and system. Background technique [0002] With the rapid development of the electronics industry, the intelligence of terminal equipment is getting higher and higher. Terminal equipment research and development companies are also paying more and more attention to intelligent and humanized design. In the context of the rapid development of terminal equipment, the convenient operation and user-friendly design of terminal equipment have become a part of terminal equipment that cannot be ignored. [0003] With the rapid popularization of mobile terminals in today's society, more and more users begin to hold two or more mobile terminal devices. Therefore, the wireless display (WFD, WiFi Display) function was born with the wave of technological development, that is, the existing mobile terminal devices The WFD function. ...
