Virtual desktop data transmission method, server, client and storage medium

The embodiment of the invention discloses a virtual desktop data transmission method. The method comprises the following steps: identifying image data of different scene areas in an image frame corresponding to a virtual desktop; performing lossy coding on the image data of the natural image area and the video area through a hardware encoder of the server to obtain image data after lossy coding; performing lossless compression on the image data of the character area and the image-text mixed area through a processor of the server to obtain image data after lossless compression; and obtaining target image data based on the image data after the lossy coding and the image data after the lossless compression, and sending the target image data to the client. The embodiment of the invention further discloses a server and a storage medium. 本申请实施例公开了一种虚拟桌面数据传输方法，该方法包括：识别出虚拟桌面对应的图像帧中不同的场景区域的图像数据；通过服务器的硬件编码器，对自然图像区域和视频区域的图像数据进行有损编码，得到有损编码后的图像数据；通过服务器的处理器，对文字区域和图文混合区域的图像数据进行无损压缩，得到无损压缩后的图像数据；基于有损编码后的图像数据和无损压缩后的图像数据得到目标图像
