Abstract
A mobile audio visual presentation system contained within a telescoping tower platform that provides height adjustment means for video display devices. The telescoping tower provides stability, transportability, versatility and optimum sound/video projection angles for multimedia audio visual presentations. The system remotely programs and controls a plurality of multimedia projection devices by interfacing ambulatory hand-held controllers, via radio frequency, to select and control multimedia elements within the system. The radio frequency signals containing desired commands are transmitted and automatically switched to multimedia devices sensitive to either infrared signals or X.10 power line carrier signal (PLC). The remote controls interface the multimedia devices in real time and provide the ability to access chosen segments of recorded video, sound and data, thereby, providing multiple operators with the freedom to interact with an audience during a multimedia presentation and vary time and sequence of events without encountering signal dropout.
