ABSTRACT:
A method of performing color control in a digital video decoder while minimizing memory bandwidth. A decoded color image bit map is stored in a RAM in lines corresponding to horizontal lines of pixels. Each line also has dedicated bytes for a corresponding color look up table comprising a control field and color address fields. Entries in separate preloaded color component tables are addressed by the color address fields. A transparency bit in the control field is used to select modifiers to the data in the address fields for transparency mode.
