Abstract:
A method of encoding or decoding coding units of a video content in a palette coding mode using an adaptive palette predictor is provided. The method includes adaptively determining a maximum size of the adaptive palette predictor based on at least one of a complexity of the video content and coding quality of the video content; and encoding or decoding the coding units of the video content in the palette coding mode using the adaptive palette predictor while limiting the adaptive palette predictor that is derived from all palette(s) of previously encoded or decoded coding unit(s) of the video content within the maximum size determined in the adaptively determining step. An apparatus of encoding or decoding coding units of a video content in a palette coding mode using an adaptive palette predictor is also provided.
