4D Sight

4D Sight develops computer-vision software that inserts or replaces advertising inside live video without requiring physical signage at the venue. It works with broadcasters, rights holders and gaming platforms, and its website names UFC, WWE and NFL among the production environments using its technology. The company says it is headquartered in San Francisco with operations in the USA and Turkey. Its platform also provides measurement tools for on-screen placements. Availability and advertising rules depend on the broadcast, market and rights agreement; this is not a consumer streaming subscription.
