A broadcast system includes a central broadcasting station 120 producing a stream of common broadcast content for transmission to a plurality of local units 140 which may be in venues such as licensed premises, hotels, leisure or retail centres or workplaces, and may have a storage unit 170. The common broadcast content may be distributed to the local units via a central unit 130. A custom content unit, which may be the central unit, stores custom content items for the local units. A production studio 180 may create the custom content items such as news items or promotional messages, and the local items may then download specific items of content or packages of content from the central unit, which are then stored in the local units storage unit 170. For example, an operator may decide locally to select certain promotional messages for playback at his particular location, from a menu of such items prepared by the studio 180 and stored on the central unit 130. A signal from the broadcast unit 110 controls when the local units cease to play common content and instead play the custom content that they have stored in their storage units. |
