Screen projection method and equipment thereof

Abstract

The invention discloses a screen projection method and equipment thereof, and the method comprises the steps that target equipment receives multiple pieces of position information which are transmitted by source equipment in real time and are used for indicating the position of an active window through a first channel, and receives display contents which are transmitted by the source equipment in real time through a second channel, and the display contents comprise active window display contents and background display contents; and after receiving one piece of position information of the active window each time, the target equipment generates a target active window according to one piece of position information of the currently received active window and the initial active window display content, and then synthesizes target display content according to the target active window and the latest background display content and displays the target display content. According to the scheme, the position information and the display content of the active window are transmitted through different channels, the target active window is generated according to the real-time received position information of the active window and the initial display content of the active window, and due to the fact that the information amount of the position information is generally small, the time delay of updating the active window by screen projection display equipment can be shortened, and the user experience is improved. The screen projection efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of terminals, and in particular to a screen projection method and equipment thereof. Background technique [0002] With the development of Internet technology, there are various types of terminal devices and various uses. In some scenarios, users have an increasingly strong demand for convenient sharing of content between the screens of multiple terminal devices, and screen projection technology can largely meet this demand of users. [0003] In the traditional wired screen projection technology, various cables are used to connect the source device and the target device to realize the display function. However, this wired screen projection method is often limited by the length of the cable, the number of host interfaces, and inconsistent interface standards on both sides. Factors, thus causing various inconveniences in actual use. In addition, in the existing wireless screen projection technology...

AI Technical Summary

Problems solved by technology

[0004] In the existing wireless screen projection technology, the content to be projected from the source device is transmitted to the target device in real time and displayed on the display screen of the target device. However, after the source device transmits the content to be projected to the target device In the process of screen content, it is usually affected by various transmission protocols and transmission bandwidth, resulting in a long time for transmitting the content to be projected. Therefore, when the content to be projected on the source device changes, the The display screen of the target device may not be able to update the display in time. For example, in a scenario that has high requirements for office efficiency, when the user moves the mouse pointer on the display screen of the source device, or drags the active window to move with the mouse pointer, the target device The simultaneous display of the mouse pointer and the active window on the display screen will cause movement lag, which makes the user's office efficiency poor
