SMPTE ST 2110 and the NETGEAR M Series for Broadcast

Today, the broadcast and professional media industries are undergoing a monumental shift. For decades, Serial Digital Interface (SDI) has been the cornerstone of video transmission. It reliably moves uncompressed video, audio, and metadata over coaxial cables. However, demand for higher resolutions like 4K and 8K keeps growing, alongside the need for more flexible production environments. Traditional SDI infrastructures are reaching their limits. Enter SMPTE ST 2110, the standard that is redefining media transport by moving it to the realm of Internet Protocol (IP).

This article explores what SMPTE ST 2110 is, along with its transformative applications and benefits. It also explains why the NETGEAR M Series of managed switches — particularly the AV Line — is the ideal network foundation for this new era of broadcast.

What is SMPTE ST 2110?

The Society of Motion Picture and Television Engineers (SMPTE) released the ST 2110 suite in 2017. It defines the transport of professional media over managed IP networks . SDI multiplexes video, audio, and ancillary data into a single, rigid stream. SMPTE ST 2110, by contrast, separates these elements into independent essence streams.

This separation means the network packages and transports video, audio, and metadata individually. Each stream is self-contained. The Precision Time Protocol (PTP), specifically the SMPTE ST 2059 standard, keeps them synchronized and ensures frame-accurate alignment across the entire network .

The ST 2110 suite breaks down into several key components:

•ST 2110-10: System Timing and Synchronization (based on PTP).

•ST 2110-20: Uncompressed Active Video.

•ST 2110-30: PCM Digital Audio (based on AES67).

•ST 2110-40: Ancillary Data (metadata, timecode, closed captions).

SMPTE ST 2110 uses standard IP networking protocols, multicast routing, and commercial off-the-shelf (COTS) IT equipment. In doing so, it bridges the gap between broadcast engineering and enterprise IT .

Applications and Benefits of SMPTE ST 2110

In practice, the transition to an IP-based media infrastructure unlocks a wealth of possibilities for broadcasters, live event producers, and AV professionals.

1. Unprecedented Scalability and Flexibility

In an SDI environment, adding a new camera feed or audio channel often means pulling new cables and expanding baseband routers. With SMPTE ST 2110, the infrastructure runs on standard Ethernet networks. Instead, adding new endpoints is as simple as connecting a device to a network switch. Facilities can therefore scale seamlessly and route any signal to any destination, free from the constraints of physical matrix routers .

2. Bandwidth Efficiency

Because ST 2110 separates media into independent essence streams, devices subscribe only to the specific data they require. For instance, an audio mixing console can subscribe solely to the ST 2110-30 audio stream. It never has to receive and demultiplex a massive 4K video payload . In turn, this significantly optimizes network bandwidth and processing power.

3. Future-Proofing for High Resolutions

The industry keeps moving toward 4K, 8K, and high-dynamic-range (HDR) content. Consequently, bandwidth requirements exceed the practical limits of traditional SDI cabling. SMPTE ST 2110 leverages high-speed IT networking, such as 10G, 25G, and 100G Ethernet. As a result, it can support tomorrow’s massive data payloads without a complete infrastructure overhaul .

4. Remote and Distributed Production

Likewise, the IP nature of ST 2110 makes it ideal for remote production (REMI). A live sports venue can send camera feeds and audio over wide-area networks (WANs) directly to a centralized control room hundreds of miles away. That reduces the need to dispatch massive broadcast trucks and crews to every event.

The NETGEAR M Series: Built for Broadcast IP

While the benefits of SMPTE ST 2110 are clear, the standard requires a robust, high-performance network backbone to function correctly. Specifically, the network must handle massive amounts of multicast traffic with zero packet loss and provide precise PTP timing. This is where the NETGEAR M Series, specifically the M4250, M4300, and M4350 managed switches, truly shines.

NETGEAR has strategically positioned its AV Line of switches to drop the barrier to entry for broadcast IP workflows. Complex network configurations become simpler and more reliable .

Key Advantages of NETGEAR M Series for ST 2110

Feature	Benefit for Broadcast and ST 2110
Out-of-the-Box AV Profiles	NETGEAR switches feature pre-configured, certified profiles for major AV-over-IP protocols. Therefore, setting up a switch for ST 2110, Dante, or NDI is as simple as selecting the profile in the dedicated AV user interface. That eliminates complex command-line configurations .
PTP Grandmaster and Boundary Clock	Above all, precise timing is the lifeblood of ST 2110. Select NETGEAR M4350 models include hardware support for PTP Boundary Clock (BC) and Grandmaster Clock (GM) modes, ensuring frame-accurate synchronization across all media streams .
High Bandwidth Options	The M4350 series scales from 1 Gigabit up to 100 Gigabit ports, providing the massive throughput required for uncompressed 4K and 8K ST 2110 video streams .
NETGEAR IGMP Plus™	Multicast traffic can easily flood a network if not managed correctly. NETGEAR’s proprietary IGMP Plus™ ensures that multicast streams are automatically and efficiently routed only to the ports that request them, right out of the box .
Redundancy and Reliability	Broadcast environments demand high availability. The M4350 series offers redundant modular power supplies, Non-Stop Forwarding (NSF), and hitless failover stacking, ensuring the show goes on even in the event of a hardware issue .

Indeed, the NETGEAR M4350 series in particular represents a massive leap forward for broadcast professionals. It integrates enterprise-grade IT features with an AV-centric design and dedicated support for SMPTE ST 2110. The result is a network solution that is both incredibly powerful and refreshingly accessible.
