For the purpose of the construction of models of messages of various formats classification of messages by structural signs at the applied level, as well as by the distribution of the information sequence on spatial co-ordinates of the message is given. Thus structure co-ordinates are chosen on an with human organs of sense perception: hearing, sense of smell - a un-dimensional system (a shift on X co-ordinate); touch - a bi-dimensional system (a shift on X,Y co-ordinates); sight - tri-dimensional system (a shift on X,Y co-ordinates within the limits of one indication of a retina (a shot) and Z dynamics between shots. Messages of various formats are represented by their images as the distribution of information sequences in spatial co-ordinates. Investigating perception processes, it is possible to estimate potentially informative processes, that is to sincle out those material objects from which one can get a maximum quantity of information does not depend on the subject of perception, it is objective and inherent in the of the analysis. The described models of estimation of potential comprehension can be used for selection of potentially informative motionless images, video images and radio signals, thereby considerably reducing data flows to information processing systems.
