Abstract

This research proposes: designing a system for transmission of digital terrestrial television under the ISDB-Tb standard for municipal channel TV operator Guaranda 5TV, in Guaranda city. For the research all factors involved in the operation of communications systems for television, whether climatic, geographic, saturation of spectrum, current status of the operator and the analysis thereof it considered was held design of a single frequency network (SFN) to study the microwave link system Digital Terrestrial Television (DTT) design in which we analyze the specific parameters that allow us to visualize the line of sight, signal level and scope of coverage depending on the geographical and topographical situation is 45 kilometers (km). For DTT system design the Google Earth application was used to determine latitude, longitude, height and topographic profiles, Radio Mobile software for the simulation of digital microwave link and analysis of system parameters. Regarding the legal aspect, the laws and regulations enacted by the CONARTEL and Superintendence of Telecommunications of Ecuador (SUPERTEL) was analyzed. An analysis of the cost of annual maintenance that will face Guaranda 5TV station with simultaneous transmission of analog and digital signal during Stage Simulcast proposed in the Master Plan was developed. With the proposed documentation system a signal is obtained by a reliability rate of 98%. It is recommended to Illustrious Decentralized Municipality of the Guaranda Canton. This study is considered as corresponding to the future implementation of Digital Terrestrial Television (DTT) in Guaranda 5TV station.
