Murat Demirci maps a full ST 2110 television campus
This article provides a high-level overview of designing and implementing a television campus utilizing SMPTE ST 2110 for live video, audio, and ancillary data over IP. It details the architecture, including PTP timing, media flow types, and switch orchestration, along with concrete VLAN and QoS configurations for network engineers. The author outlines the end-to-end integration of sources, destinations, and network infrastructure, emphasizing the role of IS-06/SDN for switch orchestration and practical bandwidth planning.
Key Takeaways
- The campus uses three planes on one fabric: media, timing, and control, with PTP, multicast RTP, and IS-06 or SDN handling different jobs.
- PTP is built on IEEE 1588-2008 PTPv2, with one grandmaster and boundary clocks in the core or aggregation layer.
- The media plane separates ST 2110-20 video, ST 2110-30 audio, and ST 2110-40 ANC/data into distinct RTP multicast flows.
- A sample VLAN plan assigns VLAN 2 to PTP, VLAN 100 to video and ANC/data, VLAN 101 to audio, and VLAN 200 to control.
- Bandwidth rules of thumb in the article cite roughly 1.2 Gbit/s for a 1080p50 2110-20 flow and 10-12 Gbit/s for 2160p50.
Why It Matters
The immediate takeaway is that ST 2110 campus design is being treated as a network-engineering problem, not just a media-format migration: timing, multicast, and QoS have to be planned together. The article’s core/access topology, VLAN split, and DSCP mapping show how broadcasters are expected to structure the fabric for cameras, playout, monitors, and recorders. On the control side, it also makes clear that IS-06 exists but is still unevenly adopted, with receiver-driven IGMP and vendor SDN often filling the gap. Watch for the article’s cited operational checks: PTP domain alignment, IGMP snooping/querier on video and audio VLANs, and whether devices lock cleanly to the grandmaster.
