A Personal Media Relay (PMR) is used to retransmit data in a system for point-to-point data streaming over a TCP/IP network. It is “Personal” because it is downloadable by end-users will onto their own personal computers (PCs) in order to help their other devices (e.g. a mobile device) send or receive data. The user installs the PMR, which is a software application, onto a personal computer (PC) that is perhaps more powerful and accesses higher Internet bandwidth than the Sender. Subsequently, the user streams data from the Sender to the PMR, which resends the live streaming data to potentially many Viewers. During PMR installation and configuration, users are given the option of allowing others to utilize their PMR as well for rebroadcasting streaming data.
