This document provides an overview of key concepts in media semiotics, including denotation, connotation, ideology, and structuralism. It explains that semiotics views media as constructing reality rather than just describing it. Meaning is produced socially and culturally through signs like words, images, and sounds. Roland Barthes was influential in semiotic analysis of media. Binary oppositions are contrasting signs that shape meaning, like urban/rural myths. Ideology refers to unconscious perpetuation of dominant beliefs through media. Producers represent prevailing values of the time without conscious intent.
