Answer 2

Video

In digital video, a reference frame is one used to define future frames within a coding format.

Physics

A reference frame is a system in which observations are made about the position or properties of physical objects. It can be a coordinate system such as the Cartesian axes, or latitiude and longitude, or a set of objects with a fixed relationship that are not accelerating with respect to one another (inertial frame of reference).

Example of a reference frame :

A passenger on an airliner, reading a book, flies directly over a friend on the ground. The person on the ground says that the book whizzed by him at 400 miles an hour. At the same moment, the passenger says that the book isn't moving at all. Both are correct within that person's frame of reference, because motion is defined according to the observer's point of view.

For the passenger of the aircraft, the aircraft and everything on it is his reference frame. For the stationary observer on the ground, everything in the aircraft is seen in motion, while he is standing still. But the person on the ground (and everything on the planet) is also in a moving reference frame, the rotating and orbiting Earth.

So there is no such thing as a "real" speed, or a "real" distance, or a "real"

location. They all depend on what you are comparing them to.
