Claim:
A method of processing image data, the method comprising acts of: receiving a bit-stream configured according to a first scheme, wherein said bit-stream includes a block of frequency coefficients that is a frequency domain representation of a block of image data; identifying frequency coefficients in the block of frequency coefficients based on a desired level of resolution and a desired level of quality; extracting the identified frequency coefficients from the block of frequency coefficients, thereby generating an extracted block of frequency coefficients; after generating the extracted block of frequency coefficients, re-sampling said extracted block of coefficients, thereby generating a resampled block of frequency coefficients; after generating the resampled block of frequency coefficients, performing an inverse quantization operation on the resampled block of frequency coefficients, thereby generating a block of inverse quantized frequency coefficients; and applying an inverse transform to the block of inverse quantized frequency coefficients, thereby generating a reconstructed version of the block of image data, wherein the reconstructed version of the block of image data has the desired level of resolution and the desired level of quality.
