Apparatus and method for encoding and decoding moving picture using wavelet transformation and motion estimation

The apparatus of claim. 1., wherein the output module comprises:

• a FIFO recording controller for gating an input of a stream FIFO and monitoring whether the stream FIFO is full or not;
• a FIFO read controller for gating an output of the stream FIFO and monitoring whether the stream FIFO is empty or not;
• a coupler for coupling the input data inputted from the wavelet module and the motion vector data inputted from the storage module;
• and
• the stream FIFO for storing the data inputted from the coupler.

A moving picture decoding apparatus, using motion estimation based on a block and a wavelet transformation based on a frame, for decoding an image signal inputted by being encoded in one bit-stream type, the moving picture decoding apparatus comprising:

• an input module for receiving the encoded image signal of the one bit-stream type;
• a wavelet module for receiving a difference signal among the image signal from the input module and reversely wavelet-transforming the difference signal;
• a FIFO for storing a signal outputted from the wavelet module;
• a storage module to which a motion vector among the image signal is transmitted from the input module and the reverse-wavelet-transformed difference signal is transmitted from the FIFO;
• a motion compensation module for compensating a motion by using the motion vector and the difference signal transmitted from the storage module;
• and
• an output buffer for finally outputting an image signal encoded by the motion compensation module received from the storage module.
