The document discusses Stuart Hall's encoding/decoding model of media texts. It explains that decoding involves making meaning from the codes within a media text, which can be visual or auditory symbols. Hall proposed that audiences can have preferred, oppositional, or negotiated readings of the codes and ideologies implicitly or explicitly presented in a media text based on their own beliefs. The document analyzes some examples of visual codes in media like magazines and games to illustrate how audiences make interpretations.
