PRINCETON, N.J.—Triveni Digital today announced that it has added ISDB-Tb capability for its StreamScope MT-70 MPEG analyzer platform. Designed specifically for Brazilian broadcasters, the solution provides comprehensive monitoring and troubleshooting capabilities for ISDB-Tb services while supporting the country’s transition to TV 3.0 (also known as DTV+), according to the company.

Triveni will showcase StreamScope MT-70 with support for ISDB-tb and TV 3.0 at the 2026 NAB Show, April 19-22, in Las Vegas in ATSC booth C1655.

In 2025, Brazil announced adoption of the physical layer of the ATSC 3.0 protocol for TV 3.0, its next generation broadcast standard.

“As Brazil transitions to TV 3.0, broadcasters need reliable, end-to-end visibility across both legacy and next-generation broadcast television services,” said Mark Simpson, president and CEO at Triveni Digital. “With StreamScope MT-70 ISDB-Tb, we’re extending our proven monitoring and analysis capabilities and empowering Brazilian broadcasters to deliver exceptional quality, quickly resolve issues, and confidently manage the complexities of operating in a dual-standard environment.”

The new version of StreamScope MT-70 seamlessly integrates with Triveni’s StreamScope Enterprise centralized quality assurance system, enabling broadcasters to monitor and analyze quality across their entire broadcast operation—from ISDB-Tb to TV 3.0 services. This unified approach is critical as Brazil enters a lengthy simulcast period where both standards will coexist on air, Triveni said.

Built with Brazil-specific support for SBTVD ABNT NBR 15603 tables and descriptors, StreamScope MT-70 ensures accurate validation and deep visibility into regional broadcast requirements. The solution is available in multiple deployment options, including rack-mount systems, software, and in the cloud, giving broadcasters the flexibility to deploy it based on their operational needs.

CINCINNATI — Broadcaster ATB Bolivia has transitioned to ISDB-Tb digital television in Cochabamba and La Paz, Bolivia, with the assistance of GatesAir and its regional partner Sonotec.

The transition fulfills a requirement of the Bolivian government to deliver digital television to the city of Santa Cruz.

“While the Santa Cruz site had an existing analog TV transmitter we were able to convert in the field, the Cochabamba and La Paz sites were very challenging as we needed new transmitters that could work with the existing RF infrastructure,” said Javier Fernandez, ATB’s CTO.

In 2011, the Bolivian government adopted ISDB-Tb. The country is in the first phase of its ISDB-Tb rollout, which is due to be finished in 2024.

ATB chose the GatesAir Maxiva ULXTE liquid-cooled transmitter for the transition in both locales. GatesAir expedited the delivery of the transmitters, which Sonotec installed. They were commissioned prior to the June deadline.

The new Maxiva ULXTEs transmit one ISDB-Tb HD channel and one mobile channel. Satellite relay extends coverage to those in rural areas. The Bolivian broadcaster anticipates adding another channel shortly, GatesAir said.

According to Fernandez, ATB has experienced “a remarkable improvement” in the quality of its transmitted signals and bandwidth efficiency.

One reason contributing to ATB’s selection of the Maxiva transmitters was the efficiency of their liquid-cooled design, which lowers the requirement for air conditioning and reduces power consumption, said Fernandez.

Regional GatesAir sales engineers conducted training seminars and on-site visits to ensure a smooth installation and commissioning, the company added.

Maxiva UAX transmitter
SAO PAULO—ISDB-Tb, Brazil’s standard for digital TV, is a CODFM-based modulation scheme that—on a pure signal transmission level—is not dissimilar to the more widely used DVB-T2 standard. However, the ISDB-Tb architecture typically carries a heavier bandwidth signal. That can quickly translate to high transport costs when delivering over-the-air content across very large geographical areas.

This is exactly the case in Brazil, where we broadcast to coastal and interior areas throughout the greater Sao Paulo region. Working with the systems design and integration specialists at Foccus Digital, we deployed a single-frequency network architecture for hybrid analog and ISDB-Tb digital TV. GatesAir transmitters comprise the network and keep our costs manageable en route to a full DTV transition.

REMUX FEATURE

The GatesAir SFN architecture comprises of 31 Maxiva UAX UHF transmitters of varying power levels (50 watts to 1kW), all synchronized to deliver content on the same frequency. From a strictly performance and quality viewpoint, the network performs as assured.

In an SFN configuration, Maxiva UAX transmitters provide an ideal manner to optimize spectrum and bandwidth for TV. GatesAir addresses the previously mentioned higher transport costs with a variety of transmitter input options that enable management and delivery of satellite, L-Band and ASI over IP sources across the network.

The Maxiva design for Brazilian TV networks integrates a multiplexing solution to “remux” the over-the-air broadcast transport stream inside the transmitter. This means that regardless of how the signal reaches the transmitter, the signal is recreated for broadcast in analog or ISDB-Tb DTV.

This is a significant operational benefit given the complex nature of managing many analog and digital signals across long distances. Remux reduces the costs of bandwidth-heavy transport and the architecture allows us to deliver more DTV-associated services, including ISDBTb mobile channels, across the Rede VTV network.

LOW LABOR AND OPERATIONAL COSTS

The plug-and-play GatesAir SFN architecture simplified both the initial rollout and commissioning of the network, as deployed and managed by Foccus Digital. Maxiva transmitters lack the intensive software programming associated with many SFN transmitter networks, often required to remove signal overlap and interference between transmitters of close proximity.

Additionally, the high reliability of these transmitters minimize our current and long-term maintenance requirements. Coupled with a modest set of common spare parts to share across the network—along with the redundant, modular and hot-pluggable architecture of Maxiva UAX transmitters—our labor and operational costs will remain exceptionally low over the life of the network.

Though Brazil has set a national analog TV shutoff for 2018, the main Rede VTV coverage cities of Campinas and Santos will turn off analog programming in 2017. Foccus Digital has designed a turnkey system for hybrid analog and ISDB-Tb programming to help prepare us for this transition. With ERI and Spinner filters and combiners to marry analog and digital signals in common antenna systems, as well as Selenio networking/encoding systems from Imagine Communications to support high-quality, multichannel DTV programming with outstanding bandwidth efficiency, the GatesAir SFN architecture has Rede VTV prepared for the DTV era well into the future.
