Signal processing concerns designing algorithms for manipulating signals to best achieve some signal-based criterion. Information theory focuses on how best to communicate and represent digital streams. What is missing from both is a consideration of the information represented by signals no matter what their form. In particular, multimedia data streams are quite complex, varied and highly interdependent. By melding aspects of signal processing and information theory, information processing theory quantifies how well signals represent information regardless of their form and how well systems process (extract information components at the expense of others) and extract information.
