ATSC Proposed Standard: Revision of A/337:2018, Application Event Delivery
Approved 29 March 2019. This document is currently at ballot as a Proposed Standard.
This document specifies the delivery of events/actions for ATSC 3.0 applications and synchronization of these application events/actions with underlying audio/video content. This Candidate Standard reversion of A/337 has the HELD and DWD signaling tables and related text removed. Those tables are being moved to A/331. An A/331 revision accommodating this change is also under development. A redline version of the document is available here.
