Propuesta de guías para el laboratorio de investigación del DETRI, enfocadas al estudio del estándar de televisión digital ISDB-Tb

Abstract

The project presents an overview of Digital Terrestrial Television standards worldwide, and focuses on the theoretical and practical study of the transmission parameters of the ISDB-Tb standard adopted by Ecuador. The study of the standard is based on a series of practical tests performed with the support of the radiofrequency equipment of Investigation and Simulation Laboratory of the Department of Electronics, Telecommunications and Information Networks (DETRI) of the National Polytechnic School. In addition, the information and tests performed with the equipment is structured as laboratory guides, whose purpose is to provide students, teachers and researchers with an understanding of the transmission system of the standard detailed in ABNT-NBR-5601. Finally, the optimal transmission and reception parameters of the television signal are determined by analyzing concepts such as: bandwidth, frequency channeling, modulation schemes, guard intervals, hierarchies and system modes in three scenarios that include: fully simulated television signals, mixed television signals simulating transmission parameters, but audio and video information is real, and a commercial television signal broadcast in Ecuador currently.
