1. A method, comprising: extracting, by a computer processor, a depth map and color data from at least one 3D image; reducing, by the computer processor, bandwidth of the depth map to produce a reduced bandwidth depth map comprising: generating a histogram of depth values in the depth map; performing a modal analysis on the histogram; identifying one or more depth values in the histogram associated with a modality in a distribution representing depth values in the depth map, wherein the modality is the most frequently occurring depth value of the one or more depth values in the distribution; and removing the identified one or more depth values associated with the modality in the depth map to produce the reduced bandwidth depth map; inserting, by the computer processor, the reduced bandwidth depth map into the color data to produce a reduced bandwidth 3D image; and transmitting, by the computer processor, the reduced bandwidth 3D image into a transmission channel for delivery to a display.
