Overview

The DigiCaster-R is DigiCAP’s software-based redundancy switch designed specifically for STLTP delivery in ATSC 3.0 and TV 3.0 workflows. The DigiCaster-R continuously monitors STL streams and automatically switches to a backup source the moment it detects an issue, ensuring uninterrupted broadcast operations. For broadcasters like TV Globo, DigiCaster-R adds a critical layer of resilience, delivering high availability and safeguarding viewer experience across large-scale deployments.
