We propose a high-speed playback method for the spatiotemporal division multiplexing electroholographic threedimensional (3D) video stored in a solid-state drive (SSD) using a digital micromirror device. The spatiotemporal division multiplexing electroholography prevents deterioration in the reconstructed 3D video from a 3D object comprising many object points. In the proposed method, the stored data is remarkably reduced using the packing technique, and the computer-generated holograms are played back at high speed. Consequently, we successfully reconstructed a clear 3D video of a 3D object comprising approximately 1,100,000 points at 60 frames per second by reducing the reading time of the stored data from an SSD.
