Classification: CPC G  H | IPC G  H

Claim 0:
1. A computer-implemented method, comprising:
dividing a frame of image data into a plurality of blocks of pixels;
analyzing a first block of pixels of the plurality of block of pixels to determine whether the first block of pixels contains at least one edge;
select a type of compression to compress the first block of pixels with based on whether the block of pixels contains the at least one edge, wherein the type of compression is selected from a group comprising lossy compression corresponding to the first block of pixels including no edges and lossless compression corresponding to the first block of pixels including the at least one edge;
obtaining at least one first value associated with at least one second block of pixels adjacent to the first block of pixels, wherein the at least one first value comprises pixel values associated with the at least one second block of pixels;
compressing the first block of pixels using the selected type of compression and based on the at least one first value to yield at least one compressed value, wherein the at least one second block of pixels is compressed separately from the first block of pixels;
setting at least one second value associated with the first block of pixels to indicate the type of compression used to compress the first block of pixels; and
encoding the at least one compressed value to produce encoding image data.
