DISTRIBUTING AUDIO VISUAL CONTENT

摘要

Audio visual content is distributed from a server (16) to stations (14). The server (16) stores pre-arranged sequences of content for each station (14). The stations (14) periodically identify themselves to the server (16) and request information identifying further content for display. The stations (14) also identify to the server the content which has been displayed. The server (16) is therefore able to verify that previous content has been displayed as requested, and to identify further content to be displayed.
