Problems solved by technology

[0002] The current method of realizing screen sharing generally establishes a connection between the source device and the client device, broadcasts and sends the code to the client for decoding, and realizes one-to-many screen sharing, but this method is easy to mistakenly connect devices that do not need to be shared. The security and reliability are not high; and when sharing, you will encounter delay problems caused by process inconsistencies between devices

Embodiment Construction

[0036] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0037] see figure 1 , which is a schematic flow chart of a screen mirroring method according to the present invention, including step S102: after the sending device detects that a connection is established with the receiving device, the sending device performs priority encoding on the content displayed on the screen; in step S104, the sending device encodes the preferentially encoded video code Stream is stored, and only the video code stream of the priority encoding of the preset duration is reserved, and the preset duration is the time length of the current time going back; when the sending device in step S106 receives the screen mirroring start instruction, it starts real-time encoding Initialize the operation and transmit the pref...

Abstract

A screen mirroring method and system, wherein the method includes the following steps: after the sending device detects that a connection is established with the receiving device, the sending device performs priority encoding on the content displayed on the screen; the sending device stores the preferentially encoded video stream, And only keep the video code stream of the priority encoding of the preset duration, the preset duration is the time length of the current time going back; when the sending device receives the screen mirroring start instruction, it starts the real-time encoding initialization operation, and will prioritize The coded video stream is transmitted to the receiving device; it enables the pre-sending of the preferentially coded video stream during the real-time coding initialization process, which solves the delay problem of the screen sharing technology.

Description

technical field [0001] The invention relates to the field of device display image sharing, in particular to a screen mirroring method and system. Background technique [0002] The current method of realizing screen sharing generally establishes a connection between the source device and the client device, broadcasts and sends the code to the client for decoding, and realizes one-to-many screen sharing, but this method is easy to mistakenly connect devices that do not need to be shared. The security and reliability are not high; and when sharing, you will encounter delay problems caused by process inconsistencies between devices. Contents of the invention [0003] Therefore, it is necessary to provide a screen mirroring method and system to solve the delay problem of the screen sharing technology. [0004] In order to achieve the above object, the inventor provides a method for screen mirroring, which includes the following steps: after the sending device detects that it h...
