Abstract
A connection is established between a first device and a server. When the first device opens the connection, the server determines the remote IP address of the first device. Determining the remote IP address can be performed in a variety of different manners. The first device is then tasked to determine its local IP address. The same steps can be repeated with a second device. Thereafter, either of the first device or the second device are able to query the server to find out if there is another device on the network. If one of the devices is capable of accepting incoming connections, the devices can communicate directly using the local IP addresses. Otherwise, messages can be sent through the server. The communication between the first and second devices can allow enhanced media viewing capabilities. Other embodiments are also disclosed herein.
