Where do spectators see the replays, at the arena on the jumbotron? On TV? On the Web?
The replays would be controlled and generated by in-house staff at the facility, becoming part of their normal flow of game-time production. The video could be displayed on the jumbotron, a feed can be patched back to the broadcast truck, or it can be pumped through to a web-based video streaming server for viewers online.
So yes! You can do all three.

Is this system really worth 5 Million dollars?
No, we don't think so. That's why it costs a LOT less. Using a mix of hardware and software not previously available, we've innovated in areas that have not been brought fully to market. By finding the right mix of vendors -- over 30 from 4 countries across the globe -- we bring the right products to the table to integrate into your existing in-house video feed. It only sounds like millions of dollars.

Is this the same system that was once seen in the Superbowl?
No. That system was produced by another company, and was far more complicated and expensive. We've introduced a more efficient (patent-pending) and more cost-effective way of achieving a similar effect.
