This paper introduces a novel approach to assist the author during the production process of new audiovisual documents from audiovisual archives. Our research relies on rhetorical tradition to relate author's intentions to forms and contents of target audiovisual discourse. We present the different levels of structure which are involved in the authoring process, together with their associated components (topic structure, intentional discourse structure, concrete discourse structure, discursive and narrative components). The paper specially focuses on reuse of audiovisual resources and shows how the context of their indexation can be articulated with the new publication context, so emphasizing the interest of multiple discursive structures interaction. We illustrate our approach with an example of TV news publication based on political TV archives.
