Abstract:
1. An apparatus to determine an inverse transform of encoded data, the encoded data comprising a plurality of compressed data elements in the frequency domain, the apparatus comprising: (a) a variable length decoder configured to receive the plurality of frequency domain compressed data elements and to translate the plurality of frequency domain compressed data elements into compressed values defining magnitude and position within a block; (b) an inverse serializer configured to receive the compressed values defining magnitude and position and to resequence the compressed values; (c) an inverse quantizer configured to decompress the values defining magnitude and position and to translate the values defining magnitude and position into individual frequency domain elements; and (d) an IDQT/IDCT transformer configured to transform the data elements from the frequency domain to the pixel domain, the IDQT/IDCT transformer further comprising:
