METHOD AND SYSTEM FOR ENCODING A 3D VIDEO SIGNAL, ENCLOSED 3D VIDEO SIGNAL, METHOD AND SYSTEM FOR DECODER FOR A 3D VIDEO SIGNAL

摘要

In a method for encoding and an encoder for a 3D video signal, centre view frames, a depth map for centre view frames and an occlusion data frame are encoded. On the basis of the depth map for the centre 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 centre view frames. Preferably the centre view frames are used as reference frames in encoding the occlusion data frames.
