How does interpolation work?

Interpolation is a process where a display unit (TV/Monitor) takes two frames and puts them together (similar to an "average") to generate an extra frame in the middle. By inserting an extra frame between each one that was recorded, you effectively double the frames per second and can bring 30 to 60.
