Encoding method, encoder and screen sharing device and system

Abstract

The embodiment of the invention provides an encoding method, an encoder and a screen sharing device and system. The method includes the steps of firstly, determining a first class of pattern layer and a second class of pattern layer according to the pattern layer properties of display data in a frame buffer area; secondly, obtaining coordinate parameters, corresponding to the first class of pattern layer and the second class of pattern layer, in a display area of a target display interface; thirdly, dividing the final display area into at least one first class pattern layer display area body and at least one second class pattern layer display area body according to the coordinate parameters, filling a blank area with transparent data, and encoding and compressing the transparent data through a corresponding encoding and compressing method to form at least one first class pattern layer encoded datum and at least one second class pattern layer encoded datum; fourthly, enabling the first class pattern layer encoded data and the second class pattern layer encoded data to serve as output code streams. In the encoding method, the encoder and the screen sharing device and system, display data are encoded and transmitted according to classifications of the pattern layer properties, and the problem of displaying a graphic video mixture on a shared screen can be solved to a certain extent.

Description

technical field [0001] Embodiments of the present invention relate to the field of image processing, and more specifically, relate to an encoding method, an encoder, a screen sharing device, and a system. Background technique [0002] Screen sharing appears after the graphical user interface (GUI). The purpose of screen sharing is to reproduce the interface display content of the host screen on the remote client, or appear in a virtual concept, so that the remote user feels like sitting Same as host. [0003] The method of screen copy sharing is mainly to transmit the data stream processed by a distortion-free or special compression algorithm to the client, and the client receives the data stream for decoding and display. [0004] However, in the prior art, for a shared screen where both pictures and videos exist, either the frame rate is low and the display is not smooth, or the details are not clearly displayed, and the display effect is poor. [0005] Therefore, there i...
