Abstract
Official abstract text for this publication.
Two or more set-top boxes are installed in a household. A communications link, preferably a physical link, is provided between or among the set-top boxes. One of the boxes is designated as a “master” box while the other box or boxes are “slaves.” The slave box will use the communications link to communicate in a secured and encrypted manner with the master box. If that communication is severed, e.g., if an attempt is made to move the slave box to another household to provide unauthorized service in that household, the slave box will stop working when it can no longer communicate with the master box.
