It then outlines some technical elements used in media like mise-en-scene, camerawork, sound, and editing. It also discusses codes, signs, and semiotics - how meaning is constructed through visual, audio and written codes and signs in media texts.

Key theorists like Saussure, Peirce and Barthes are mentioned for their contributions to understanding signs and myth-making in media.
