Creation and application method of dynamic virtual channel based on remote display protocol

The invention provides a creation and application method of a dynamic virtual channel based on a remote display protocol. The method is as follows: installing a virtual channel data switching service program at a server side, and installing a virtual channel plug-in unit at a client side; creating a static virtual channel for communicating with client side program by the virtual channel data switching service program; and calling corresponding application programming interfaces by the server application program to register dynamic virtual channel and process data transmitting and receiving operations. The method of the invention packages data of virtual channel packets to dynamically expand one static virtual channel into multiple virtual channels and support dynamic creation.
