Is it possible to track a tennis match in real time?

understand that the ball is going back and forth
estimate the distance between the players
detect a racket/ball hit
estimate the average speed of the ball
detect floor collisions inside/outside the court
...

Then interpret all this information and show to the public in a big screen in real time.

If this is not possible, how far are we from that?

Can we introduce some restrictions to make it work somehow, e.g., smaller court, bigger ball, etc.?

Yes it is possible, see HawkEye (ELC - Understanding the tennis ball bounce ). There are always some preconditions to make it works:

multiple cameras strategically located
cameras calibrated (intrinsics (focal length, distorsion, ...) + extrinsics (how each cameras are related to each other))
high framerate cameras
...

If you don't have any experience in computer vision, simple tennis ball tracking should be feasible more or less easily (HSV color segmentation for instance).
