Abstract
Subject matter includes methods of using conventional set-top boxes that receive streaming video modulated on coaxial cable rather than over an IP-based LAN as nodes in a media network. In one implementation, an exemplary adapter is used to integrate a conventional set-top box into a media network. In one implementation, an exemplary filter is used to reserve frequencies for communications between a conventional set-top box and a hub and to prevent communications from leaving a media network. In one implementation, an exemplary content protection method provides a way of encrypting program content on the media network in a manner that a conventional set-top box can decode.
