Abstract
Los elementos necesarios para un receptor de television digital estan estructurados como una pluralidad de bloques que procesan la senal digital y un bloque que procesa la operacion aritmetica hospedera. Los bloques estan conectados a traves de un bus o colector para propositos generales. Las instrucciones para controlar las operaciones de los bloques y los datos de una corriente se transfieren a traves del bus. Cuando en cada bloque se coloca un codificador/decodificador para encriptacion, es posible proteger los contenidos transferidos a traves del bus. Cuando se ubica un circuito codificador/decodificador para encriptacion en una interfaz a la cual se conecta una tarjeta enchufable para expansion, es posible proteger los contenidos que salen de la interfaz.
