Claim One:
1. A method for processing image data that has been encoded using a discrete cosine transform to provide reduced image data having a relatively lower definition than the image data, the method comprising the steps of: receiving image data that has been encoded using a discrete cosine transform; processing the received image data with an inverse discrete cosine transform (IDCT) to cause IDCT processed image data to be generated, wherein the IDCT processed image data has the same definition as the image data, separately processing the received image data with an inverse discrete wavelet transform (IDWT) to cause IDWT reduced image data to be generated, wherein the IDWT reduced image data has a relatively lower definition than the image data; and generating reduced image data using both the IDCT processed image data and the IDWT reduced image data, wherein the reduced image data has a relatively higher definition than the IDWT reduced image data and a relatively lower definition than the image data.
