Abstract: There are disclosed various methods, apparatuses and computer program products for video encoding. The type of prediction used for a reference picture index may be signaled in the video bit-stream. The omission of motion vectors from the video bit-stream for a certain image element may also be signaled; signaling may indicate to the decoder that motion vectors used in prediction are to be construed at the decoder. The construction of motion vectors may take place by using disparity information that has been obtained from depth information of the picture being used as a reference.

Abstract: There are disclosed various methods, apparatuses and computer program products for video encoding/decoding. In some embodiments the method comprises signalling a long-term palette information, where the long-term palette information comprises at least information on the color values for each entry in the long-term palette; generating a palette that is used for coding a coding unit by either selecting at least one color value from a long-term palette or by separately signaling at least one color value, or performing both. Alternatively the method comprises constructing a long-term palette during an encoding process or a decoding process; and updating the long-term palette dynamically after coding a coding unit, and constructing a palette used for encoding or decoding a coding unit using information from the long-term palette.

Abstract: There are disclosed various methods, apparatuses and computer program products for video encoding and decoding. In some embodiments, to indicate a composition of pictures of different time instants, some usability information may be embedded to the video bitstream indicating the intended display behavior when more than one layer is used and associated display behavior using this information. More specifically, the embedded information may indicate how the layers need to be composed in the video bitstream. The information may indicate if the intended display behaviour is to combine (overlay) base layer and enhancement layer decoded pictures. The information may indicate that the base and enhancement layer decoded pictures are allowed to be overlaid. In addition or alternatively, the information may indicate that the enhancement layer picture should not be combined with base layer picture during display.
