I believe it is the same system. The camera is dangled over the stadium
from pillars at the four corners. Four stepper motors release or pull each
wire independently in small steps, positioning the camera anywhere in the
3-D space above the stadium. Three additional degrees of freedom allow
rotating the camera, tilting it up or down, and zooming it.
The software controls the entire system. Predetermined trajectories are
programmed into the computers to move the camera swiftly from one place to
another. For example: go to the pole vault pit, or follow lane 1 on the
track.
