Abstract

Se instalan dos o mas cajas de television por cable en un hogar. Un enlace de comunicaciones, preferentemente un enlace fisico, se proporciona entre las cajas de television por cable. Una de las cajas se conoce como caja "maestra", mientras que la otra caja o las cajas se conocen como caja(s) "subordinada(s)". La caja subordinada utilizara el enlace de comunicaciones para comunicar en forma segura y criptografiada con la caja maestra. Si se corta dicha comunicacion, por ejemplo si se intenta desplazar la caja subordinada hacia otro hogar para proporcionar un servicio no autorizado en dicho hogar, la caja subordinada dejara de funcionar cuando ya no pueda comunicar con la caja maestra.
