TV 3.0: Technology Overview

TV 3.0, in the final specification phase by the SBTVD Forum, brings together the best in Digital TV technology in the world, with many Brazilian innovations. MIMO transmission, designed for internal antenna reception, IP-based, complete and transparent integration between broadcast and internet, application-based user interface, UHD HDR video, immersive and customizable audio, advanced accessibility features and emergency alerts, personalized content and geographically segmented, are some of the characteristics of the new system. Find out more about the TV technology of the future, explained by those responsible for coordinating the development of these specifications.

Chair: Luiz Fausto de Souza Brito, Chair – Technical Module, SBTVD Forum

Luiz Fausto has over 20 years of experience in media technology. At Globo since 2006, he is currently a Technology & Regulatory Specialist. He has chaired the SBTVD Forum’s Technical Module since 2020 and has been a member of the Brazilian Delegation to ITU-R and CITEL PCC.II since 2013 and of SET since 2009. At ITU-R, he co-chairs the Future of Broadcasting Rapporteur Group and chairs SWG 6B-2 (Multimedia). He holds a Master’s in Applied Computing, an MBA in IT, and a Bachelor’s in Electronic Engineering.

TV 3.0 as an Application-Oriented TV Platform

TV 3.0 represents a paradigm shift in the way viewers perceive and navigate broadcast content. Consumption no longer begins with selecting a broadcaster’s channel, but rather with selecting its app. This transition means that the range of broadcasting services is now offered in a harmonized format, in a dedicated environment that aggregates broadcasters’ OTA/OTT content, full of personalized and immersive experiences. All of this is based on the pillars of national technology that positions the country as a historic contributor to the state of the art in interactive TV.

Speaker: Marcelo F. Moreno, Associate Professor, Federal University of Juiz de Fora (UFJF) | Technical Module of the SBTVD Forum

Associate Professor at the Federal University of Juiz de Fora (UFJF), Brazil, with a Ph.D. in Computer Science from PUC-Rio and expertise in multimedia systems and computer networks. He was a Visiting Professor at the International Audio Laboratories Erlangen (FAU/Fraunhofer IIS) in 2022–2023. He co-edited ITU-T Recommendation H.761 (“NCL and Ginga-NCL”) and has contributed to several international standards, having chaired ITU-T working groups for over a decade. Since 2015, he has coordinated the Application Coding Working Group of the Brazilian Digital TV System Forum (SBTVD), where he also serves as editor of ABNT standards for TV 2.5 and TV 3.0. His research bridges academic innovation and standardization, with a focus on application-oriented broadcasting, second-screen integration, audience measurement, and privacy-aware media platforms for next-generation digital TV.

TV 3.0 technological status

The presentation will cover the progress of actions in the subtitles, audio coding and video coding working groups at the SBTVD Forum. The maturity of the technological ecosystem will also be presented with the example of the demonstrations carried out during the 2024 Olympics.

Speaker: Carlos Cosme, Researcher at Medialech Lab - Globo | Member of the Technical Module - SBTVD Forum

Carlos Cosme holds a degree in Electrical Engineering from Universidade Estácio de Sá (2007), a postgraduate degree in Control and Automation Engineering from Universidade Gama Filho (2011) and a specialization in Computer Networks from PUC Rio (2013). He has been with Globo since 1998, where he worked in the areas of operation, support and currently works as innovation specialist in the Telecom group of the Infrastructure and Security Hub. He is a member of the Sistema Brasileiro de Televisão Digital (SBTVD) Forum, where he coordinates the Audio coding, Captions and Video coding working groups for TV 3.0 project. At Globo, he focus on broadcast and broadband technologies that can increase and/or improve the quality of experience for viewers consuming Globo's products.

TV 3.0 Transport and Physical Layer

This presentation will cover the innovative transport and physical layer features used in TV 3.0. The transport layer uses the DASH Internet protocol in conjunction with ROUTE and allows content to be received over the air and over the Internet. The ATSC 3.0 system with MIMO extensions has been recommended in the physical layer. It includes using two cross-polarized antennas in transmit/receive, which allows up to double the channel capacity. LDM allows the multiplexing of PLPs in two layers with different Modcods, allowing mobile and fixed reception with an internal antenna with unequal error protection and an identifier called TxID that allows the origin of the transmitted signal to be identified, facilitating geographical segmentation.

Speaker: Cristiano Akamine, Professor and Researcher, Digital TV Laboratory, School of Engineering, Mackenzie Presbyterian University | SBTVD Forum Technical Module

Received the B.Sc.degree from Mackenzie Presbyterian University, Sao Paulo, Brazil, in 1999, and the M.Sc. and Ph.D. degrees from the State University of Campinas, Sao Paulo, in 2004 and 2011, respectively,all in electrical engineering. He is a Professor of Embedded Systems, Software Defined Radio, and Advanced Communication Systems, Mackenzie Presbyterian University. Since 1998, he has been a Researcher with the Digital TV Research Laboratory, Mackenzie Presbyterian University, where he had the opportunity to work with several digital TV systems. His research interests are in SoC for broadcast TV and software defined radio.

Advances and Proposals for Accessibility and Emergency Alarms in TV 3.0

The talk will present proposals for improving accessibility and emergency alarms on TV 3.0 in Brazil. The challenges and advances in the implementation of subtitles, audio description and LIBRAS will be addressed, with a view to ensuring the inclusion of people with disabilities. In addition, solutions will be discussed for the transmission and presentation of effective visual and audible alerts, ensuring that everyone has access to information in situations of risk.

Speaker: Guido Lemos, Full Professor at the Center for Informatics at UFPB | Secretary of Science and Technology of João Pessoa

PhD in Computer Science from the Pontifical Catholic University of Rio de Janeiro (PUC-RIO). He coordinates LAVID (Research and Extension Center in Digital Video Applications), where he conducts research in the following areas: digital television, digital cinema, distributed multimedia applications, video distribution networks, distributed artistic performances, accessibility, information security, fake news, telehealth, and blockchain applications. He participated in the development of the Ginga middleware, published as ITU-T and ITU-R recommendations, and adopted as the standard in the Brazilian Digital Television System and in several other Latin American countries. Its implementation is a software currently installed on approximately 100 million TV sets. Other highlights of his research include the development of a system for storage, transmission, and display of 4K 3D videos called Fogo Player; the development of a platform to support distributed performances in dance, theater, and music called Arthron; the development of video servers for live and on-demand streaming, called DLive and DVod, which were used in RNP’s Digital Video Network and in USP-SP’s IPTV service; the accessibility software VLibras (used on the websites www.brasil.gov.br, senado.leg.br, and câmara.leg.br), executed 1.5 billion times per year; the development of technologies for registration, validation, and preservation of Digital Diplomas based on blockchain, which will be used in 270 public universities in Brazil; and finally, the development of the V4H health video system, which uses digital signature technologies, blockchain registration, and preservation to enhance security in the use of videos generated during medical consultations. He was the coordinator of the REUNI program at UFPB and participated in its creation and implementation, resulting in an increase from 20,000 to 45,000 undergraduate and graduate students. He also serves as a member of the Deliberative Council of the Brazilian Digital Television System Forum and is a guest of Ancine’s Technical Accessibility Chamber.
