Title:
METHOD AND TECHNICAL EQUIPMENT FOR VIDEO ENCODING AND DECODING
Document Type and Number:
WIPO Patent Application WO/2015/140402
Kind Code:
A3
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.
