<p>The present invention is embodied in a system for building a data compression encoder (38) for use with the discrete cosine transform compression process (48). The invention results in enhanced compression using the discrete cosine transform by constructing a prediction engine (46) that breaks the data received into predicted and unpredicted portions. The predicted portions are excluded from the discrete cosine transform reducing the time required to compress a file. The prediction engine (46) relies, in part, upon look-up tables that are developed by the present invention to determine the predicted blocks. A table build engine and database compiler are used to create the look-up tables.</p> |
