ABSTRACT:
A portable multimedia marketing system is useful for playing back prerecorded audiovisual presentations. A portable carrying case holds the various components which include an audio and video playback device for playing the presentations. A presenter's monitor is used by the presenter to monitor the video portion of the presentation and a hand-held customer monitor is used by the person to whom the presentation is directed for viewing the video portion of the presentation. A pair of loudspeakers removably mounted within the carrying case provide the audio portion of the presentation. While the loudspeakers may be removed, from the carrying case, they are designed to remain in the case during use. Various umbilicals provide power, audio and video signals to or from the individual components.
