Abstract: Advances in the Brazilian television sector have been consistently intertwined with the technological innovations of each era. From its beginnings supporting only live broadcasts, through the integration of content recorded on magnetic tapes, to the adoption of a color standard, broadcasts have always been characterized by the search for higher quality. Currently, the Brazilian Terrestrial Digital TV Forum (SBTVD) is working on a new national standard, called TV 3.0, which, among several guidelines, aims to incorporate multiple secondary devices, such as smartphones, Head Mounted Displays (HMDs), and sensory effects renderers for improving interactivity and immersion, and providing viewers with a richer content experience. In this context, this paper presents the first efforts in this direction, proposing architectural changes in the Ginga middleware to accommodate these new devices and functionalities, as well as a communication protocol for this new environment that is envisioned. Furthermore, two use cases are presented to validate these concepts, along with a brief discussion on the pros and cons of these new services and how they can find full applicability in the next generation of terrestrial TV system in Brazil.
