Motion Compensation in MPEG
In MPEG, images are predicted from previous frames (P frames) or bidirectionally from previous and future frames (B frames). B frames are more complex because the image sequence must be transmitted/stored out of order so that the future frame is available to generate the B frames.
After predicting frames using motion compensation, the coder finds the error (residual) which is then compressed and transmitted.

Famous quotes containing the words motion and/or compensation:
“If we shall stand still
In fear our motion will be mocked or carped at,
We should take root here where we sit, or sit
State-statues only.”
—William Shakespeare (1564–1616)
“Senators and presidents have climbed so high with pain enough, not because they think the place specially agreeable, but as an apology for real worth, and to vindicate their manhood in our eyes. This conspicuous chair is their compensation to themselves for being of a poor, cold, hard nature.”
—Ralph Waldo Emerson (1803–1882)
