Abstract
An adaptive method of lossless compression of video data (46) including evaluating a block of consecutive video data values, selecting one mode of a plurality of possible lossless data compression modes based upon the evaluation of the block, compressing the video data values (50) to the selected mode to result in compressed video data values for the block, and adding an indication of the selected mode to the compressed video data values for the block.
