TV Mode is when you can change the shutter speed of the camera for taking pictures while the subject is in motion. When the mode is set at a high fraction number, like 1/4000, the lens will will open and close back up very quickly, so the picture comes out sharp and in focus even though the things were moving around. It looks really cool because you can catch things midaction, like Bruce doing a flip and breakdacing in these pictures.
When you set the TV mode to a low fraction number, like 1/60, the motion of your subject gets slightly blurred, so you can see the several spots it was in throughout the motion.
Here you can see how Bruce is blurry to show his flipping motion, while the background stays clear.
Here, he was doing a head spin.
