ABSTRACT:
A system for communicating content streams (e.g., voice, video, data) between a content server connected to a network and a remote electronic device. In one implementation, the network is a power-line communication (PLC) network and the remote device is configured for ultra-wide band connectivity with an interface module. The interface module is a power-line communication/ultra-wide band (PLC/UWB) module preferably connected to a conventional power outlet on the network. The interface module converts the power-line signals from the server to ultra-wide band signals which are broadcast for reception by the wireless electronic device. Return communications with the server from the wireless electronic device are also preferably supported. The power-line communication and/or ultra-wide band signal can also be encrypted for improved security. The content server and interface module are preferably configured to communicate content streams only within the portions of the bandwidth allocated by a bus master, which may be a content server with programming for controlling bandwidth use on the physical power-line communications network. In another implementation, the content is sent to the remote device over a connection to the Internet.
