SUMMARY:

Digital Terrestrial Television (DTT) services still play an important role in Brazil in delivering media content to a large number of people. Besides the growing penetration of broadband connectivity and overthe-top services, television broadcasting is still the main platform for providing information, entertainment, and culture, especially in economically less favored regions. Furthermore, second-generation DTT systems are already internationally standardized and in operation in many countries. These new technologies provide essential enhancements such as High Definition (UHDTV) video transmissions with High Dynamic Range (HDR) and Wide Color Gamut (WCG) capabilities, immersive audio techniques, and new generations of middleware platforms, which will bring new converged broadcasting-broadband experiences to viewers. To allow the evolution of DTT services, spectrum availability should be deemed for deploying new technologies. Hence, in this work we study the current and future spectrum availability of the 174-216 MHz VHF band and 470-698 MHz UHF band in Brazil for the deployment of second-generation Digital Terrestrial Television Systems, which are being studied under the “TV 3.0 Project” initiative, coordinated by The Brazilian Digital Terrestrial Television System Forum (SBTVD Forum). Coverage simulations using the Recommendation ITU-R P.1812 were computed for all expected operating television stations, in different scenarios, to estimate the spectrum usage over the Brazilian territory. Results indicate that even after the analog TV switch-off there will be no spectrum availability in the main metropolitan regions for simulcast transmissions between the current ISDB-Tb System and the future TV 3.0. Hence, hybrid approaches should be implemented to smoothly introduce a new digital television system in Brazil.
