A method of converting video data from a YUV format to an RGB format comprising (a) performing a matrix transformation of Y, U and V pixel data of a set of possible Y, U and V parameters into corresponding R, G and B parameters, (b) determining whether the set of R, G and B parameters forms a first lookup table whose size exceeds the size of a particular memory space, (c) in the event the lookup table is too large for the memory space, truncating least significant bits of at least the U and V parameters, (d) repeating steps (a), (b) and (c) until the first lookup table fits the memory space, and then storing the first lookup table in the memory space, and (e) using the first lookup table to provide RGB pixel data using the YUV data as addresses thereto.
