The authors discuss recent updates to the Brazilian digital TV (DTV) standards to better combine TV broadcast and internet services without interrupting existing TV services. They focus on improving the middleware layer, which helps run apps on TVs, specifically the Ginga system used in Brazil. Their work highlights advances in the Ginga D-profile, enabling new uses for DTV receivers while maintaining compatibility during the transition from analog to digital TV. This effort was carried out by the Brazilian DTV Forum with academic collaboration.

Abstract
The Brazilian DTV system standards have been recently revised in order to address new use cases related to deeper integration be- tween broadcast services and broadband services. Such an evolution could not disrupt the current DTV services since Brazil and many ISDB-T countries are still under the switch-off process from ana- log to digital. The middleware layer is the best candidate for such an incremental (yet powerful) evolution. In the case of Ginga, the Brazilian DTV middleware, as an open platform based on receiver profiles, the results were impressive. In this paper, we focus on the advances and new use cases addressed by the D-profile Ginga DTV receiver specification carried out in the Brazilian DTV Forum under a collaborative effort led by the Academia
