Claim:
1. A three dimensional source device for transferring a three dimensional video signal to a three dimensional destination device, the three dimensional source device comprising: an output circuit arranged to generate the three dimensional video signal, wherein the output circuit is arranged to transfer the three dimensional video signal to the three dimensional destination device, wherein the three dimensional source device is arranged to provide a source depth map relating to the three dimensional video signal, wherein the three dimensional video signal comprises: a source stereo-to-depth convertor circuit arranged to generate a second generated depth map based on first video information and the second video information; and a source depth processor circuit arranged to provide a depth helper data only when a difference between the source depth map and the second generated depth map exceeds a predetermined threshold, wherein the three dimensional destination device comprises: a depth processor circuit for generating a destination depth map based on the first generated depth map when none of the depth helper data is available in the three dimensional video signal, and based on the depth helper data when the depth helper data is available in the three dimensional video signal.
