Stereoscopic video is one of the simplest forms of multi view video, which can be easily adapted for communication applications. Much current research is based on colour and depth map stereoscopic video, due to its reduced bandwidth requirements and backward compatibility. Existing immersive media research is more focused on application processing than aspects related to transfer of immersive content over communication channels. As video over packet networks is affected by missing frames, caused by packet loss, this paper proposes a frame concealment method for colour and depth map based stereoscopic video. The proposed method exploits the motion correlation of colour and depth map image sequences. The colour motion information is reused for prediction during depth map coding. The redundant motion information is then used to conceal transmission errors at the decoder. The experimental results show that the proposed frame concealment scheme performs better than applying error concealment for colour and depth map video separately in a range of packet error conditions.
