Abstract
A video processing system for reducing data content requirements along a transmission path. A movement processor which includes a framestore is capable of detecting both interfield and interframe movement and uses this to manipulate the data so as to inhibit or attenuate the movement content so that the available bandwidth is not exceeded. This manipulation can also be used to provide residual movement persistence between frames and to reduce picture noise content. A processor at the remote end of the transmission path can reconstitute the data to make it available at normal video rates.
