A method includes the step of intercepting, by a recorder, a presentation layer protocol data stream representing display data and comprising a plurality of packets, during transmission of the presentation layer protocol data stream from a first device to a second device. A protocol engine uses information associated with at least one copied packet to regenerate the display data represented by the at least one copied packet. In another aspect, a foreground protocol engine receives a request for rendering the contents of a packet in a presentation layer protocol data stream comprising a first plurality of packets already received and a second plurality of packets yet to be received. The foreground protocol engine displays, during transmission of the presentation layer protocol data stream from a first device to a second device, the requested packet responsive to an identified state-snapshot having an associated timestamp previous to that of the requested packet. |
