Culture is not a homogeneous whole; its dynamic character results from the fact that within its boundaries various „languages" operate, which are an expression of man’s semiotic activity. His culturegenerating role in the realm of nature consists of continuous transformation of nature into culture. Thus he generates various texts (both artistic and non-artislic) which are sequences of relevant signs arranged in a special manner. The signs have to be arranged according to a defined set of norms a id regulations, otherwise the given text is likely to lose its consistency. No text can exist beyond a given semiotic system; occasionally the existence of certain texts depends on several systems (for instance film texts). The notion of a text is not identical with the notion of an artistic work. The relation between the two corresponds to the signal-sing relation. * At the rnomeiv. it is difficult to explain the semiotic processes in the domain of film, as well as to define the segmentation of particular codes involved in their decipherment. Neither is it possible to say what a film sign is. Hence the interrogation mark in the title, indicative of the „incapacity" of present statements of purely arbitrary character.
