PROBLEM TO BE SOLVED: To enable a plurality of persons can enjoy different videos and audios with one display by periodically time-division displaying a plurality of video signals on the same screen and opening a shutter glasses only at a selected period. SOLUTION: For instance, four pieces of video signals and audio signals are inputted, and are signal processed respectively to be supplied to FIFOs 14A-14D. A memory controller 21 outputs a write-in clock of a regular frequency to the FIFOs 14A-14D also to write in the data, and further, outputs a read-out clock of a regular frequency in order of field to control so as to read out from the FIFOs 14A-14D. Then, shutter drive signals are generated from respective shutter glasses drive circuits 20A-20D synchronized with an odd field and an even field of four pieces of video signals, and the shutters of the shutter glasses 2A-2D are opened/closed by these signals. |
