Brazil’s next-generation broadcast television system, TV 3.0 (publicly branded as “DTV+”), is a regionally optimized configuration of the ATSC 3.0 suite of standards. It is arguably the ATSC 3.0 system’s most technically advanced implementation to date. Developed to satisfy a comprehensive set of requirements defined in Brazil for its next-generation digital television platform, the TV 3.0 standards mandate numerous features that are optional in other ATSC 3.0 configurations, while excluding certain elements considered mandatory elsewhere. It also introduces additional components not present in earlier configurations.

As ATSC 3.0 continues to expand into new markets, TV 3.0’s selective adaptation provides a compelling illustration of how a versatile, modular core standards set can be both constrained and extended to address specific requirements in local technology, regulatory, and market conditions.

This paper examines the principal differences among the current U.S., Korean, and Brazilian configurations of ATSC 3.0 technologies. It discusses ATSC’s ongoing efforts as an international Standards Development Organization (SDO) to accommodate these variations by incorporating regionally originated extensions into the ATSC 3.0 core standards as they evolve, thereby fostering greater interoperability while enabling all participating regions to evaluate and potentially benefit from the resulting innovations.
