A/371, “Delivery of ATSC 3.0 Services for Redistribution”Approved: 14 April 2026

This Recommended Practice describes methods for transporting ATSC 3.0 Services for Redistribution, including both Direct Feed distribution and OTA delivery, ensuring smooth distribution to service operators such as MVPDs, Virtual MVPDs, and other similar service providers. In this framework, content feeds such as those managed by STLTP, DSTP, and Essence handlers play a critical role, facilitating the secure and seamless delivery of ATSC 3.0 content to service operators. Additionally, this practice incorporates OTA delivery as a failover mechanism, enabling (v)MVPDs to maintain access to ATSC 3.0 Services in the event of primary distribution interruptions, ensuring high signal quality for downstream distribution to end-users. While this recommended practice is intended to cover all ATSC 3.0 features and how they may be delivered to a (v)MVPD by OTA reception or by Direct Feed, not all (v)MVPDs have the ability, for technical reasons, to carry all ATSC 3.0 features described here. Such situations are often subject to commercial agreements, which are beyond the scope of this document.
