Abstract:
Embodiments are described which exploit a finding, according to which a higher compression rate or better rate/distortion ratio may be achieved by adopting or predicting second coding parameters used for encoding a second view of the multi-view signal from first coding parameters used in encoding a first view of the multi-view signal. In other words, the inventors found out that the redundancies between views of a multi-view signal are not restricted to the views themselves, such as the video information thereof, but that the coding parameters in parallely encoding these views show similarities which may be exploited in order to further improve the coding rate.

Claim (Index 1):
A decoder for decoding an encoded video data stream to generate a multi-view video, the decoder comprising:\n a view decoder configured for: extracting, from a data stream using a processor, first information associated with a first coding block in a first view of a multi-view video signal, wherein the first information is indicative of whether a motion parameter of the first coding block is to (a) be read from the data stream independent of another coding parameter, or (b) reuse one or more coding parameters of a second coding block located in a second view of the multi-view video signal; if the first information indicates that the motion parameter of the first coding block is to be read from the data stream independent of another coding parameter, extracting, using the processor, the motion parameter of the first coding block from the data stream; if the first information indicates that the motion parameter of the first coding block is to reuse the one or more coding parameters from the second coding block in the second view:\n receiving, using the processor, the one or more coding parameters including a motion parameter of the second coding block, \n predicting, using the processor, the motion parameter of the first coding block based on the motion parameter of the second coding block, and \n extracting prediction error data associated with the motion parameter of the first coding block; \n generating, using the processor, a prediction of the first coding block based on (i) the extracted or predicted motion parameter of the first coding block, and (ii) the prediction error data if the first information indicates that the motion parameter of the first coding block is to reuse the one or more coding parameters; obtaining, from the data stream using the processor, residual data associated with the first coding block; and reconstructing, using the processor, the first coding block using the prediction of the first coding block and the residual data to produce a part of a video frame in the first view of the multi-view video.
