Abstract

recepção de uma pluralidade de elementos de sintaxe que são indicativos de uma paleta que foi usada para codificar um bloco de dados de vídeo, a pluralidade de elementos de sintaxe incluindo um primeiro elemento de sintaxe que indica uma série de valores de paleta para a paleta que são explicitamente sinalizadas no fluxo de bits de vídeo codificado, em que o primeiro elemento de sintaxe é codificado usando um ou mais códigos de golomb de modo que o comprimento do primeiro elemento de sintaxe codificado seja menor ou igual a um número máximo predeterminado de bits, decodificação da pluralidade de elementos de sintaxe, incluindo a decodificação do primeiro elemento de sintaxe usando um ou mais códigos golomb, reconstrução da paleta com base na pluralidade decodificada de elementos de sintaxe e decodificação do bloco de dados de vídeo usando a paleta reconstruída.
