ABSTRACT:
In some embodiments of the present invention, frequently occurring inverse linear transform results are calculated and stored in look-up-tables. In real time, incoming blocks of linear transform coefficients are divided into two or more groups. A numerical code is determined for each group and checked against a look-up-table for that group to see whether it corresponds to a pre-calculated inverse linear transform result.
