Abstract

método e aparelho de sinalização de alto nível para predição ponderada. a presente invenção fornece um método de codificação, em que o método compreende: determinar elementos de sintaxe a serem codificados, em que os elementos de sintaxe incluem uma estrutura de lista de imagens de referência e pelo menos um parâmetro de predição ponderada de sintaxe de alto nível (hls); codificar o pelo menos um parâmetro de predição ponderada de hls; e codificar a estrutura de lista de imagens de referência seguindo a codificação do pelo menos um parâmetro de predição ponderada de hls. os elementos de sintaxe são reordenados de modo que codificar a estrutura de lista de imagens de referência possa ser baseada em valores do pelo menos um parâmetro de predição ponderada de hls.
