摘要： A method, medium, and apparatus hierarchically encoding or decoding an image format. In this method, a basic image is generated by down-sampling an original image. A basic layer bitstream is generated by encoding the basic image. A restoration image of the basic image is generated and up-sampled. Enhancement layer bitstreams are generated by encoding a residue image corresponding to a difference between the original image and the up-sampled restoration image by using different quantization parameters.
