The present invention provides a packet based communication medical system for communicating video, voice and medical data between a central monitoring station and a patient monitoring station located remote to the central monitoring station. The patient monitoring station obtains digital video, voice and medical measurement data from the patient, seals the data in a packet and sends the packet through the network to the central monitoring station. Since the information is sealed in packets, the information can be transmitted over a wireless or asynchronous transmission mode (ATM) network, a publicly connected television (CATV) network, a public switched telephone network (PSTN), an integrated services digital network (ISDN), It can be sent over various forms or combinations of network structures, including the Internet, local area networks (LANs), and wide area networks (WANs). Therefore, separate transmission protocols do not require different types of transmission media, respectively. Rather, a single transport / network layer protocol is used to seal the information in packets at the transmitting end and to open the information at the receiving end. Moreover, by sending information in packets, video, voice and measurement data can be integrated and sent over a single network.
