Methods and devices for applying motion compensation to wavelet encoded video images and for transmitting the motion compensated wavelet encoded video images. One aspect of the invention involves an encoding device and method operable for organizing wavelet encoded images into a plurality of bit-planes, inverse wavelet transforming selected ones of the bit-planes wherein an image corresponding to the inverse wavelet transformed bit-planes is representative of said video image and estimating motion between the video image and the inverse wavelet transformed images. Another aspect involves, a transmitting device and method for identifying a type of frame and initiating a first significance based transmission process when a first type of frame is determined and initiating a second significance based transmission process when a second type of frame is determined. |
