Abstract
método e aparelho para inicialização e gerenciamento de paleta um método e um aparelho para codificação de paleta de um bloco de dados de vídeo pela inicialização da paleta ou da paleta tripla ou usando-se uma paleta selecionada ou uma paleta tripla a partir de uma área de imagem precedente para o bloco de começo da área de imagem atual são expostos. 0 método recebe dados de entrada associados a uma área de imagem atual consistindo em múltiplos blocos. para o bloco de começo, o previsor de paleta é determinado com base em uma paleta inicial ou uma paleta tripla ou com base em uma paleta selecionada ou uma paleta tripla associada a um bloco selecionado localizado em uma localização antes do fim de uma área de imagem precedente. para blocos da área de imagem atual, uma codificação de paleta é aplicada aos blocos, em que pelo menos um bloco usa o previsor de paleta para o bloco de começa como o previsor de paleta.
