Proceso de cambio de equipamiento análogo a digital en las estaciones de tv abierta

Abstract

This research is focused on the detailed analysis involving the transmission shift from analog to digital broadcast TV stations in Ecuador, taking as reference points the study and facilities Telerama channel. The investigation begins with a brief explanation of the different departments that contains a television station and their respective functions, followed by the instrumentation used to obtain audio and video. It also examines the technical structure of an analog channel from capture and generation of audio and video signals to your radio broadcast RF signals, using schematic diagrams describing the various phases through which the signal passes through: monitoring, processing and transmission stations of the same operator through guided media (coaxial cable, optical fiber) and unguided (microwave, satellite). Then we describe the structure of a digital channel by publicizing the benefits to viewers, and the changes brought to transmit digitally. Finally, we show the design of a digitized channel and approximate investment required in equipment operators to transmit under the standard adopted by Ecuador.
