A plurality of media data, including audio data or audio/video data, are stored in a central database. A plurality of in-room, user interface systems access the media data through a central server. The central server presents to the in-room system a selection menu through which at least one of the media data may be selected. Upon selection of a media data by the user interface, the central server accesses the selected media data from the central database and transmits it to the in-room system. The media data may be transmitted by downloading the data to an intermediate system, playing the media data at the intermediate system and outputting the played media data to the in-room system through a communications line. The media data may also be transmitted by streaming the media data to the in-room system through a communications line. The central server may present to the in-room system any of a number of additional menus including a purchase menu through which the selected media data may be purchased, an activation menu through which communication between the in-room system and the central server may be established for a period of time, a radio menu through which any of a plurality of programmed media-data channels may be accessed and a mood menu through which the brightness of the image displayed on the in-room system video monitor may be affected.
