Abstract: Techniques are disclosed for a user-mode based remote desktop protocol (RDP) encoding architecture. A user mode desktop application and user mode virtual channel application run in user-mode session space. Virtual channel data from the virtual channel application is marshaled and sent to a RDP encoder process in user-mode system space. There it is converted to RDP protocol data units (PDU) and sent to a remote client across a communications network. Graphics data from the desktop application is sent to a display driver in kernel-mode session space and then to a graphics reflector that marshals the graphics data and sends it to the RDP encoder for a similar transformation.

Abstract translation: 公开了用于基于用户模式的远程桌面协议（RDP）编码体系结构的技术。 用户模式桌面应用程序和用户模式虚拟频道应用程序在用户模式会话空间中运行。 来自虚拟通道应用程序的虚拟通道数据被编组并发送到用户模式系统空间中的RDP编码器进程。 在那里它被转换成RDP协议数据单元（PDU）并通过通信网络发送到远程客户端。 来自桌面应用程序的图形数据被发送到内核模式会话空间中的显示驱动程序，然后发送到图形反射器，该反射器将图形数据编组并发送给RDP编码器以进行类似的转换。
