This paper presents a mathematically solid framework for the study of audio-visual contents based on the development by Keith Devlin of situation theory. In order to obtain this framework, we present accounts of the processes carried out by agents from the reception of the audio-visual content to the extraction of information, in accordance with the definition by Israel and Perry. We finally justify why these accounts concerning the extraction of information from audio-visual content can be included as part of a mathematical formulation of situation theory.
