Abstract
In a method for encoding and an encoder for a 3D video signal, center view frames, a depth map for center view frames and an occlusion data frame are encoded. On the basis of the depth map for the center view frame a distinction is made between functional and non-functional data in an occlusion data frame. This allows a strong reduction in bits needed for the encoded occlusion data frame. In the decoder a combined data stream is made of functional data in the encoded occlusion data frames and the center view frames. Preferably the center view frames are used as reference frames in encoding the occlusion data frames.
