Accelerating the Shift to SMPTE ST 2110: The Future of IP Broadcast Production
The broadcast industry is currently navigating a pivotal transition from traditional Serial Digital Interface (SDI) infrastructures to IP-based production workflows. At the heart of this evolution is the SMPTE ST 2110 suite of standards, designed to provide the scaling, flexibility, and remote connectivity that modern media environments demand. Although the transition isn’t without its hurdles, new industry initiatives are accelerating the pace of adoption.
- SMPTE ST 2110 allows professional media to be sent over managed IP networks.
- SDI remains the dominant backbone in 82% of broadcast operations as of 2026.
- The standard breaks media into separate “essences” (video, audio, and metadata) for greater flexibility.
- Adoption is being driven by new-build requirements and the need to replace aging SDI facilities.
Understanding SMPTE ST 2110
SMPTE ST 2110 is a comprehensive suite of standards developed by the Society of Motion Picture and Television Engineers (SMPTE). Unlike previous methods, ST 2110 describes how to send digital media over an IP network in a way that prioritizes quality and flexibility over bandwidth efficiency.
The foundation of these standards is built upon work previously published by the Video Services Forum (VSF). The core innovation of ST 2110 is the concept of “essences.” Instead of bundling audio, video, and metadata into a single stream, ST 2110 carries them as separate individual streams. This allows engineers to route, process, and manage each element independently.
The ST 2110 Standard Breakdown
The suite is divided into several specific parts to handle different aspects of the production chain:
- ST 2110-10: Focuses on system architecture and synchronization, utilizing RTP, SDP, and PTP.
- ST 2110-20: Manages uncompressed video transport, based on SMPTE 2022-6 and IETF RFC 4175.
- ST 2110-30: Handles audio transport, based on the AES67 standard.
- ST 2110-40: Manages the transport of ancillary data.
The Challenge of Migration
Despite the advantages, migrating an entire facility to ST 2110 is a complex undertaking. According to a 2026 Haivision annual survey on global broadcast tech trends, SDI still serves as the dominant production backbone in 82% of broadcast operations. Industry leaders, including Matrox Video’s Samuel Recine, have noted that migrating entire facilities to 2110 isn’t easy, and users often face significant hurdles during the process.
Yet, the momentum is shifting. Broadcasters are increasingly moving toward IP production due to inevitable migrations triggered by aging SDI hardware and the specific requirements of new facility builds.
Real-World Application: ITN Productions
The practical benefits of this shift are evident in recent deployments. London-based ITN Productions recently launched a new IP-based production control room (PCR) designed to deliver daily news coverage across two newsrooms. By combining the TAG Video Systems Realtime media platform with Matrox Video ConvertIP decoders, ITN has achieved reduced latency and greater flexibility, providing a fully configurable monitoring system.
Technical Synchronization and Stability
A critical component of a successful ST 2110 deployment is precise timing. The integration of Precision Time Protocol (PTP) through SMPTE ST 2059 is essential for reliable operations. While the Boundary Clock Manager (BMCA) provides a robust framework for synchronization, the use of Dynamic Priority can further enhance system stability, ensuring that broadcast services remain uninterrupted.
Frequently Asked Questions
What is the main difference between SDI and ST 2110?
SDI (Serial Digital Interface) is a traditional point-to-point hardware connection. ST 2110 is an IP-based standard that allows media to be routed over a network, treating video, audio, and metadata as separate streams (essences) rather than a single combined signal.
Why is ST 2110 preferred for high-conclude production?
It’s intended for environments where quality and flexibility are more important than bandwidth efficiency, allowing for easier scaling and remote connectivity.
How is synchronization handled in IP workflows?
Synchronization is managed via SMPTE ST 2059, which integrates PTP (Precision Time Protocol) to ensure all devices in the network are perfectly aligned.
Looking Ahead
As the industry continues to move away from the constraints of SDI, the adoption of SMPTE ST 2110 will likely accelerate. The combination of new industry initiatives, the necessity of upgrading legacy hardware, and the proven success of IP-based control rooms suggests a future where managed IP networks are the universal standard for professional media production.
