Hybrid video coding supporting intermediate view synthesis

An encoder for encoding multi-view data, comprising:

• a prediction unit configured to encode multi-view data comprising data related to a first-view video and a second-view video, wherein to encode the multi-view data, the prediction unit is at least configured to determine a disparity vector and a prediction residual associated with a sub-region of a frame of the second-view video, the disparity vector indicating a spatial displacement of the sub-region of the frame of the second-view video with respect to a frame of the first-view video;
• and a data signal generator configured to insert the multi-view data including the disparity vector and the prediction residual into a data stream, wherein data associated with a portion of the frame of the first-view video and a scaled disparity vector are used to synthesize a portion of a frame of a third-view video, and the scaled disparity vector is determined using the disparity vector and a scaling factor.

A method for encoding a video comprising:

• encoding multi-view data comprising data related to a first-view video and a second-view video, the encoding multi-view data comprising:
• determining a disparity vector and a prediction residual associated with a sub-region of a frame of the second-view video, the disparity vector indicating a spatial displacement of the sub-region of the frame of the second-view video with respect to a frame of the first-view video;
• and inserting the multi-view data including the disparity vector and the prediction residual into a data stream, wherein data associated with a portion of the frame of the first-view video and a scaled disparity vector are used to synthesize a portion of a frame of a third-view video, and the scaled disparity vector is determined using the disparity vector and a scaling factor.

A non-transitory computer-readable medium for storing data associated with a video, comprising:

• a data stream stored in the non-transitory computer-readable medium, the data stream comprising multi-view data including at least a first-view video and a second-view video, the multi-view data comprising a disparity vector and a prediction residual associated with a sub-region of a frame of the second-view video, wherein the disparity vector indicates a spatial displacement of the sub-region of the frame of the second-view video with respect to a frame of the first-view video, wherein data associated with a portion of the frame of the first-view video and a scaled disparity vector are used to synthesize a portion of a frame of a third-view video, and the scaled disparity vector is determined using the disparity vector and a scaling factor.
