摘要：
Disclosed is a system of transporting multimedia based on network, and more particularly, to an apparatus for inserting, transporting and extracting a timestamp through a network protocol. A network timestamp is transported without changing a preset transport standard such as a UDP, an RTP and a MPEG-2 standard by adding a packet having a timestamp, which is used to compensate for network jitter and used for synchronization, to a packet stream transported through a UDP or an RTP.
