Broadcast Gateway

ATSC 3.0 gateway/scheduler

Triveni Digital ATSC 3.0 Broadcast Gateway

The new Broadcast Gateway from Triveni Digital encapsulates ROUTE and MMTP inputs and sends STLTP outputs to ATSC 3.0 exciters.

For Next Get TV broadcasting

Broadcast Gateway User Interface

The Broadcast Gateway can receive multiple IP streams from encoders, such as GuideBuilder XM, to generate L1 and L2 signals for transmission. It's easily configured to allows multi-subframe and multi-PLP delivery, and supports and external clock.

In a variety of networks

Broadcast Gateway Network Topology

The Broadcast Gateway is well-suited for TV networks that are transitioning to ATSC 3.0. (Click to enlarge.)

With the Broadcast Gateway, TV stations can implement and manage revenue-enhancing ATSC 3.0 services in a variety of network configurations. Integrated with Triveni Digital’s GuideBuilder XM encoder, the Broadcast Gateway ensures an easy transition to Next Gen TV broadcasting.
