220.127.116.11 Delayed Rendering of Clipboard Data
Delayed rendering is a data transfer principle that makes it possible to keep two clipboards in sync while minimizing the network bandwidth required for communication. The underlying premise of delayed rendering is that data needs to be provided only when requested. When a copy operation takes place, the actual data associated with the Clipboard Format (section 18.104.22.168) is not copied onto the remote clipboard. Only the format ID that represents the Clipboard Format is placed on the clipboard. The data associated with the Clipboard Format is sent only if a paste operation is executed. The Remote Desktop Protocol: Clipboard Virtual Channel Extension requires that the system clipboard support delayed rendering of data to ensure the efficiency of clipboard synchronization.
