Innovation

Next-Gen Broadcast Features

Designed to integrate seamlessly into live production trucks and cloud-based overlay workflows.

Low Latency

Engineered for live, low latency broadcasts. Features less than 64ms of end-to-end processing delay, keeping line overlays in perfect sync with live play-by-play video feeds.

👁️

Intelligent Player Occlusion

Advanced real-time chroma keying and depth estimation ensure player feet and jerseys remain naturally layered on top of the virtual lines, maintaining realistic field depth.

🤖

AI Field Tracking

No external sensors required. Our AI models continuously detect turf line intersections, camera pan/zoom/tilt angles, and camera configurations to auto-calibrate lines dynamically.

🎨

Brand & Sponsor Overlays

Monetize high-impact moments. Insert dynamic, high-fidelity sponsor logos and advertisements directly onto the field turf alongside standard virtual markings.

FAQ

Virtual First Down Line & Yellow Line Questions

What is the yellow line in football called?

The yellow line you see on the field during TV football broadcasts is a virtual first-down line — a graphic overlay inserted live onto the video feed to mark how far the offense needs to advance the ball for a first down. It isn't painted on the field; it's rendered in real-time by a first-and-10 line insertion system like the IOVS F10.

What is a "first and 10" system?

A first-and-10 system is the broadcast technology that tracks the camera and field geometry in real-time and inserts the virtual first-down (yellow) line and yardage markers directly into the live video, while keeping players and the ball layered naturally on top.

How does the virtual first down line work?

The IOVS F10 uses AI-based field and camera tracking — no on-field sensors required — to continuously calculate camera pan, tilt, and zoom, then renders the yellow first-down line and yardage overlays in perfect perspective on the turf, with player occlusion so athletes always appear in front of the line.

Can the yellow first-down line technology be used for other sports?

Yes. While the yellow line is most associated with American football, the same virtual line insertion technology can be configured for soccer offside lines, rugby distance markers, and other sports that benefit from real-time on-field overlays.
