与其他远程控制软件相比，为什么 RDP 如此之快? [英] Why is RDP so fast compared to other remote control software?

问题描述

我使用基于 RDP 的 Windows 远程客户端桌面实用程序从我的笔记本电脑连接到我的桌面.它比 TeamViewer 等远程控制应用程序更快且看起来更好.

I use RDP-based Windows' Remote Client Desktop utility to connect to my desktop from my laptop. It's much faster and looks better than remote control applications like TeamViewer etc.

出于好奇，为什么 RDP 更好?

Out of curiosity, why is RDP better?

谢谢.

推荐答案

RDP 是一种特定的协议，它允许传输低级屏幕绘制操作.它还知道屏幕上的像素图实体.例如，它了解何时绘制图标并将其缓存(通常以有损压缩格式)在客户端.

RDP is a specific protocol which allows to transmit low-level screen drawing operations. It is also aware of pixmap entities on the screen. For example it understands when an icon is drawn and caches it (typically in a lossy compressed format) on the client side.

其他软件没有这种低级访问:它等待屏幕改变，然后重新传输屏幕或改变区域的捕获.每当屏幕发生变化时，都必须传输像素图表示.因为这通常是有损压缩，所以看起来也更糟.

Other software does not have this low-level access: It waits for the screen to change and then re-transmit a capture of the screen or the changed regions. Whenever the screen changes, a pixmap representation has to be transmitted. Because this is lossy compressed in general, it also looks worse.
