ATSC Standards Update: New Amendment Approved
Since the last issue of The Standard newsletter, an amendment has been approved and will be published soon on ATSC the web site. Document S32-653r3, “ATSC Proposed Recommended Practice: A/327:2024-04 Amendment No. 1, SISO Operation of MIMO-Capable Transmitters,” was approved by the ATSC membership in a ballot that closed on 3 December 2024. This amendment adds a description of MIMO (Multiple-Input Multiple-Output) / SISO (Single-Input Single-Output) combo operations. The latest changes in A/322:2024-09, “Physical Layer Protocol,” and work in process on A/324:2024-04, “Scheduler / Studio to Transmitter Link,” relating to joint MIMO, LDM, and Channel Bonding allow for SISO operation to be mixed with MIMO operations. This amendment clarifies that application.
PlugFest Opportunity
PlugFests are an important tool for successful implementation of ATSC 3.0. Given the complexity of various ATSC Standards, PlugFests provide a valuable opportunity to test new designs and optimize existing designs. One ongoing PlugFest is focused on testing updates and revisions to A/331, “Signaling, Delivery, Synchronization, and Error Protection.” The project, supported by NAB and News Press & Gazette, utilizes live signals to “road test” the standard. This effort not only helps improve the functionality of commercial products but also provides feedback to ATSC specialists on areas of the standard that may be unclear or need revision. If your company is interested in this project, please reach out to the chair of S33 or to Kelly Williams at NAB to join the roster. The live test bed is located at the NP&G station in Santa Barbara, CA, which is implementing NEXTGEN TV features with support from key vendors.
