Tech Papers 2023: This paper presents how Globo and SBTVD Forum showcased Brazil’s next-generation digital TV technologies (TV 2.5 and TV 3.0) during the FIFA World Cup 2022, featuring immersive audio, 4K HDR video, and interactive broadcast-streaming integration.
Abstract
In 2016, the Sistema Brasileiro de Televisão Digital (SBTVD) Forum decided to update the current digital terrestrial television (DTT) system, using a two-step approach: extending the life span of the existing DTT system through a backward-compatible evolution (TV 2.5 Project) and starting the development of the next-generation DTT system (TV 3.0 Project). While the deployment of TV 2.5 started in 2020, the TV 3.0 standard will be finalized in 2024 and is expected to launch in 2025.
