Methods and systems for capture, replay and real-time seeking in remote presentation protocols

A recorder intercepts the protocol-data stream which is transmitted to the 2nd device from the 1st device and containing two or more packets, and a protocol-data stream expresses display data. A recorder copies at least one packet of a protocol-data stream. A recorder creates record of a protocol-data stream using at least one copied packet. Protocol engine reads at least one copied packet in record of a protocol-data stream. Protocol engine carries out regeneration of the display data expressed by the protocol-data stream using the information related with at least one copied packet.
