Patent ID: 7397962

Claim:
A method for reducing datastream transmission bandwidth requirements, comprising: in response to determining that an image data structure is present in a datastream, wherein the image data structure contains data of an image; extracting said image data structure from said datastream; dividing said image data structure into one or more subregions; associating a corresponding identifier with a first selected one of said one or more subregions; in response to determining that said first selected one of said one or more subregions is substantially identical to a second selected one of said one or more subregions, replacing second selected one of said one or more subregions with said corresponding identifier of said first selected one of said one or more subregions; reducing transmission bandwidth requirements by generating a packaged image, which includes a decoding table comprising said first selected one or more subregions and said corresponding identifier of said first selected one of said one or more subregions in place of said second selected one of said one or more subregions, wherein the decoding table contains all identifiers needed for decoding the data stream; and inserting said packaged image into said data stream; and transmitting said modified data stream.
