A media recognition system comprises an object management space, an object processing module and a media object space for storing media objects generated by object processing, wherein a pattern definition list stored in the object management space includes a plurality of action statements defining script programs to be executed in association with pattern formulas which designate the attributes of objects. The object processing module generates a new media object having different attributes by executing media processing corresponding to the input media object based on the pattern definition list, and repeats recursive media processing on the generated media object as the new input media object in accordance with the pattern definition list.
