Overview of ST 2110: Its Fundamentals

In the rapidly evolving world of broadcast technology, SMPTE ST 2110 IP video systems have emerged as the gold standard for high-end professional environments. These systems offer uncompressed, tightly synchronized, and modular streaming capabilities, making them ideal for live sports, multi-camera studios, and master control centres.

The latest trends and best practices for AV integrators involve tailoring ST 2110 implementations to specific use cases and environments. For instance, ST 2110 is best suited for high-end professional broadcast environments requiring separate routing of video, audio, and ancillary data streams with frame-level sync through Precision Time Protocol (PTP). It supports uncompressed video and ensures deterministic latency, essential for live production.

Successful ST 2110 deployment demands multicast-capable networks and full PTP-aware equipment, including switches with grandmaster and boundary clock functions to ensure precise time synchronization. For example, NETGEAR's M4350 switches now have built-in grandmaster and boundary clocks to support ST 2110 deployments.

In many real-world applications, ST 2110 coexists with protocols like IPMX to cover different deployment needs – ST 2110 for core broadcast and IPMX for outreach and lighter AV setups. Cross-protocol gateways and FPGA-based adapters enable interoperability across these environments.

Recent developments in hardware and software solutions have further bolstered the appeal of ST 2110. Ross Video's Carbonite Hypermax, for instance, supports multi-viewing and routing in a hyperconverged form, while Grass Valley's ACE 3901 gateway manages hundreds of SDI to IP transitions. Advanced monitoring and analysis tools by Tag Video Systems support uncompressed and compressed streams with real-time transcoding and signal analysis.

Panasonic's KAIROS platform updates now include multi-unit control, seamless integration with major graphics platforms, and expanded resolution support. Additionally, Panasonic’s Media Production Suite adds AI-based features such as AI Keying and advanced auto-framing for PTZ cameras, improving operational efficiency within ST 2110 workflows.

To ensure reliability and redundancy, broadcast communications solutions like RTS’s ODIN intercom system (fully compliant with ST 2110) emphasize robustness in critical broadcast communications.

Best practices for AV integrators implementing ST 2110 systems include deploying and verifying a fully PTP-synchronized network with multicast routing and proper Quality of Service (QoS) to meet deterministic latency requirements. They should also invest in management and orchestration frameworks like NMOS for device discovery and stream connection management to maintain operational simplicity.

Planning for hybrid workflows combining ST 2110 with complementary protocols (IPMX, NDI) via gateway devices can maximize interoperability and flexibility. Selecting hardware and software that support seamless integration with third-party production platforms, graphics, and AI-based processing tools can streamline deployments and enhance content quality.

In summary, SMPTE ST 2110 offers a flexible and future-proof alternative to traditional SDI infrastructure. Building an ST 2110 system is relatively easy and doesn't need to be all IP or nothing. Modern buildings often have 10G Ethernet cables installed, allowing users to take advantage of existing infrastructure for ST 2110 systems. Optical fiber Ethernet is a cost-effective option for ST 2110 systems at 10G speed, compared to 25G or 40G Ethernet.

IP video allows consolidation of equipment by managing both network and video functions. Point-to-point ST 2110 connections can be as simple as an Ethernet cable between a rack and a monitor converter or camera, providing remote power and bidirectional video. Video-over-IP technology is revolutionizing workflows and becoming more prevalent in products.

NMOS-enabled products are beneficial in larger ST 2110 systems, as they describe how devices are discovered and controlled on IP networks. SMPTE ST 2110 supports 4K, HDR, and other emerging formats and is vendor and video format agnostic. It is gaining traction as an option for Pro AV users seeking flexibility with connections, resolutions, and frame rates.

When using an Ethernet switch, a controller is needed to manage all handshakes. Some companies offer free software controllers. Users can send sources to multiple buildings using IP video and ST 2110-based converters without needing a dedicated cable for every source and destination. ST 2110 allows users to split the video and audio stream, saving bandwidth in case of a poor connection. In larger ST 2110 systems, users can connect their video gear to an Ethernet switch and configure the switch to make connections between devices.

ST 2110 products are designed for various industries, not just the IT world. As the adoption of IP video continues to grow, it's clear that SMPTE ST 2110 is leading the charge in revolutionising broadcast workflows.
