Design of IP sharing device for multimedia streaming using UDP datagram switching mechanism

In this paper, we propose a mechanism to support switching of multimedia services toward one display equipment among others connected to IP sharing device especially in home network. For this, we developed a client agent mounted on display equipment for recognizing of user's information, a switching agent mounted on IP sharing device, which is related to IPtables management in the device, and embedded board with NAT(Network Address Translation) function. A user can be provided a seamless multimedia service with his information without other signaling procedure between multimedia streaming server and IP sharing device.
