Abstract
A system and corresponding method for adjusting the brightness and color of MPEG encoded video images. A digital versatile disk player capable of decoding a previously encoded MPEG video signal and adjusting the brightness and color of the entire previously encoded MPEG video signal based on a subset of information contained in the encoded input signal. The brightness and color adjustments are performed while the encoded MPEG video signal is in the frequency (dct) domain before motion compensation is performed. The digital versatile disk player also determines whether the particular block to be decoded is of a predetermined type and decodes such block accordingly.
