Abstract

Sistemas multimedia interactivos que incluyen canal de retorno. Tiene por objeto la participación del usuario final en el funcionamiento del sistema. Se constituye mediante la asociación funcional de una estación principal (HUB), interface entre los proveedores de servicios y el satélite (S); y, estación/es secundaria/s (ES), que hace/n de interface entre las estaciones de usuario (EU) y el satélite (S) en el canal de retorno (CRE), estaciones de usuario (EU) que disponen de un modem que demodula la información del satélite (S).Interactive multimedia systems that include return channel. Its purpose is the participation of the end user in the operation of the system. It is constituted by the functional association of a main station (HUB), an interface between the service providers and the satellite (S); and, secondary station / s (ES), which acts as an interface between the user stations (EU) and the satellite (S) in the return channel (CRE), user stations (EU) that have a modem that demodulates satellite information (S).
