White Paper – ST2110-41: Revolutionizing IP-Based Metadata Workflows

Executive Summary

SMPTE ST 2110-41 is a pivotal standard within the SMPTE ST 2110 suite, designed to enhance the transport of metadata in IP-based broadcast infrastructures. It enables the carriage, synchronization, and description of separate elementary essence streams over IP for real-time production, playout, and other professional media applications. This standard has been under discussion for several years, but the SMPTE specifications were recently approved in March 2024 and now complete the 2110 family of standards related to IP transport.

In traditional Serial Digital Interface (SDI) systems, metadata is embedded within the same stream as audio and video, leading to challenges in flexibility and scalability. SMPTE ST 2110-41 addresses these issues by allowing for the separate routing of video, audio, and metadata streams over IP networks. This separation facilitates more efficient workflows and enables broadcasters to manage each component independently, leading to improved operational efficiency.  Utilizing standard Ethernet networks, SMPTE ST 2110-41 enables broadcasters to expand operations by adding metadata streams without the need for new physical infrastructure. This scalability is crucial to accommodate the growing demand for high-quality content and services. 

In summary, SMPTE ST 2110-41 plays a crucial role in modernizing metadata transport within IP-based broadcast infrastructures, offering enhanced flexibility, scalability, and future-proofing capabilities for broadcasters.
