No. of bitstreams: 1 Renato de Melo Faria.pdf: 4613150 bytes, checksum: 69b6e3b76d003f29092583ba8cd22c48 (MD5) Previous issue date: 2008-06-27 / In broad terms, this work suggests a new premise for the planning of channels of digital TV that focuses on optimizing spectrum. It made a contextualization on the decrees, laws and regulations concerning the Digital TV in Brazil. It presents the most relevant technical aspects of the Brazilian System of Digital Terrestrial Television (SBTVD-T), particularly those ones that can in any way affect the use of the spectrum. It will be presented with the Basic Plan of Distribution Channels for Digital Television (PBTVD) and the assumptions that have guided its construction. A new proposal is focused considering that each broadcaster uses only one channel in some specific region and holds a case study of this proposal in the micro of Campinas, State of S?o Paulo. This work concludes with an analysis of the results of case studies and presents opportunities for future work. / De forma ampla, este trabalho prop?e uma nova premissa para o planejamento de canais de TV Digital que privilegia a otimiza??o de espectro. ? feita uma contextualiza??o sobre os decretos, leis e regulamentos que tratam da TV Digital no Brasil.
