Abstract: There are disclosed various methods, apparatuses and computer program products for video encoding/decoding. In some embodiments the method comprises decoding a coding unit being coded with palette coding, wherein an indication of a scan order of the palette mode is decoded for said coding unit. Mode information for at least one pixel within the coding unit is decoded. Depending on the mode information, a decoded pixel value is set based on indicated scan order; or an indication to determine the number of the pixels sharing the value and indication for a reconstruction value of number of pixels are decoded; or an indication for a reconstruction value of a pixel is decoded.

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 the method comprises coding motion information of an enhancement layer using motion vector information of a reference layer, wherein the coding comprises deriving a candidate list of motion vectors using at least one of motion vector information from the reference layer; motion vector information from the enhancement layer of the same picture; and motion vector information from the enhancement layer of a different picture. The method further comprises constructing a second candidate list of motion vectors using the first candidate list; and selecting a motion vector for said coding from said candidate list. There are also disclosed corresponding method for various methods, apparatuses and computer program products for video decoding.
