RESUMO

This work presents an approach to the network relay station for free broadcasting television that may constructed with the future digital television in Brazil based on COFDM modulation. Differently of the traditional system, the network relay in multi frequencies (MFN), the proposal here described considers the use of a net in only one frequency (SFN) for the network relay. The initial point is the current network with multiple analogical channels of existing network relay. Its covering will have to be talked back by the new net in an unique channel where only one TV programming passes through. The modification proposal presents advantages for the network relay broadcasting television destined to extend its covering in a local area with some cities being gotten environment of a much more controlled and safe net. The work presents covering simulation showing that the possibility to work with nets SFN appears as a faster alternative of accomplishment of the Digital TV for the regional area of Brazil
