Abstract

sinalização de preditor de paleta com código run length para codificação de vídeo. técnicas para codificar um vetor de predição binário para predizer uma paleta para codificação de vídeo baseada em paleta são descritas. em um exemplo, um método de decodificação de vídeo compreende receber um vetor de predição binário codificado para um bloco atual de dados de vídeo, decodificar o vetor de predição binário codificado usando uma técnica de decodificação run length, gerar uma paleta para o bloco atual de dados de vídeo baseado no vetor de predição de binário, o vetor de predição binário compreendendo entradas indicando se ou não entradas de paleta previamente utilizadas são reutilizadas para a paleta para o bloco atual de dados de vídeo e decodificação do bloco atual de dados de vídeo usando a paleta.
