Abstract

sinalização de dados para imagens de referência de longo prazo para codificação de vídeo. um codificador de vídeo codifica um cabeçalho de fatia para uma fatia de dados de vídeo. o cabeçalho de fatia inclui um elemento de sintaxe que compreende informações de identificação para uma imagem de referência de longo prazo, em que as informações de identificação são explicitamente sinalizadas no cabeçalho de fatia ou derivadas de um conjunto de parâmetros de sequência que corresponde à fatia. quando o elemento de sintaxe indica que as informações de identificação para a imagem de referência de longo prazo são sinalizadas explicitamente, para codificar o cabeçalho de fatia, codificador de vídeo é também configurado para codificar um valor para as informações de identificação para imagem de referência de longo prazo no cabeçalho de fatia.
