Patent ID: 6985528

Claim:
An apparatus for encoding a moving picture by using wavelet transformation based on a frame and motion estimation based on a block comprising: an input module for receiving original image data; a wavelet module for wavelet-processing the data received through the input module; a motion estimation module for obtaining a motion vector; a motion compensation module for motion compensation by using the motion vector; a storage module for storing the original image data being transmitted from the input module, the motion rector being transmitted from the motion estimation module, and difference signal data being transmitted from the motion compensation module, and for transmitting the stored data to a corresponding module according to request of the corresponding module; an output module for outputting one bit stream by coupling the data being inputted from the wavelet module with the motion vector being inputted from the storage module; and a control module for controlling operations of the respective modules, wherein said motion estimation module comprises: at least one input buffer for storing data being transmitted from the storage module; and an input buffer controller for controlling an output sequence of the data stored in the at least one input buffer.
