ATSC STANDARDS UPDATE: A/324:2022-06 PUBLISHED

Since the last issue of The Standard an update of A/324, “Scheduler / Studio to Transmitter Link,” has been published.

A/324 specifies the protocol for the Studio-to-Transmitter Link (STL) from the studio-side infrastructure to one or more set of transmitters. It also defines possible interfaces among the studio infrastructure and specifies certain constraints on the scheduling of content and signaling in the Physical Layer.

The newly published A/324:2022-06 version incorporates changes approved in an amendment titled, “MIMO Configuration in Broadcast Gateway.” This amendment added a new annex that provides a guideline for MIMO configurations from the Broadcast Gateway. The new Annex is in response to requests from implementers for additional guidance. The amendment was approved on 13 June 2022.
