Medición y evaluación de parámetros de calidad en la recepción de señales de televisión digital vía satélite fundamentado en el estándar DVB-S, mediante el equipo Tv Explorer HD.

Abstract

This research was developed for measuring and evaluating the quality parameters of the signals reception in digital satellite television based on digital video broadcasting -satellite (DVB-S) the same which was defined for the MPEG-2 transport frame due to lack of information and few studies in this area. It was applied the satellite Amazon 2 which has frequencies in the bands C, Ku and Ka located at 61 ° W. An 11302H transponder was also used with horizontal polarization at a central frequency of 1552.97 MHz. This research was considered as a technological proposal the same which required a study through the application of methods and techniques of a basic/application research. Regarding the data collection about the materials and equipment used for developing the manual, it was necessary to take into account the descriptive research for listing some processes to be followed. A receiving system was developed for which a TV Explorer High Definition (HD) of the latest technology was handled using the established values for reception parameters and thus evaluate the signal quality of the digital channel the same which is being studied. A non- experimental study was developed for the evaluation of parameters identifying its characteristic through the observation and tests. A NetUpdate4 program was applied for gathering data in order to generate illustrations in the Matlab software to gain a better understanding. Finally, it is concluded that the studied channel and the development of the practices manual allowed to evaluate and visualize an acceptable quality in the signals perceptions of digital television via satellite. It is recommended to foster further studies based on any of the topics discussed in this research and encourage a better understanding in one of the most important communications systems which is known as digital satellite television.
