Estudio e implementación de un sistema de acceso condicional para un servicio de tv pagado.

Abstract

Study and implementation of a conditional access system for a tv paid service of the Telecommunications and Nets Electronic Engineering School at ESPOCH. The main reason for the development of this theme is the vulnerability in the transmission of the services that current Tv providers supply. Therefore, the applied method is the GMS communication which aims to set a safe access control to the service. The implemented system is made up of two circuits, a coder and a decoder that will work together through GMS communication, simulating the function of a provider central with its corresponding client, which functioning base is the remote access that will allow, through SMS codification, the service activation to the final consumers after making a prove of the equipment series numbers, with them it is assured that the number of registered benefactors will only be those that pay for the service. The results obtained throughout this process is the efficiency of an access system that disables the signal theft by people strange to the terminal. It is concluded that a new way of conditional access, practical and economical is the one that is introduced in this project, using a micro controlled intervention system that allows the conditioned access either physically or remotely. Finally, it is recommended the development of a quantifiable study that allows a marketing incursion to this new product.
