Abstract

Preferred data compression and decompression processes (500, 600) of this invention speed transmission of a color XGA image (502). A first compression step employs an RGB-to-YCrCb color conversion compression process (504), and a second step employs an Lempel-Ziv-Oberhumer ('LZO') compression process (506) for generating compressed image data for transmission through a wireless transmission medium. A preferred data decompression process receives the compressed image data from the LZO compression process. A first decompression step employs an LZO decompression process (602), and a second decompression step employs a YCrCb-to-RGB color conversion decompression process (604) for generating decompressed data suitable for rendering an image (606) that is substantially the sane as the original XGA image.
