Predict a new frame from a previous frame and only code the

prediction error

• Prediction error will be coded using an image coding method (e.g.,

DCT-based as in JPEG)

• Prediction errors have smaller energy than the original pixel values

and can be coded with fewer bits

• Those regions that cannot be predicted well will be coded directly

using DCT-based method

• Use motion-compensated prediction to account for object motion

• Work on each macroblock (MB) (16x16 pixels) independently f-Predict a new frame from a previous frame and only code the
