Proposal for the Harmonization of Digital Terrestrial Television Networks in Colombia Using a MultiCriteria Decision Process

In Colombia, the third and eighth phases of Digital Terrestrial Television (DTT) were deployed by the public (RTVC) and private (CCNP) National Broadcasters, respectively. However, considerable difficulties have been evidenced in the reception of the signal of the public channels in some zones of the country, compared with the ease to access the TV signal of the National Private Channels.This article shows a practical case of analysis applying a multicriterion decision-making method called the analytic hierarchy process or AHP. This method was used to propose a way to harmonize the transmission power levels of the TV stations of the Colombian public and private channels, by evaluating the technical, legal, regulatory, economic, political, social, and environmental implications of the different alternatives.
