Abstract

resumo uma forma explícita para sinalizar uma imagem colocalizada para codificação de vídeo de alta eficiência (hevc) um sistema é fornecido para determinar uma imagem de referência colocalizada para permitir codificação e decodificação de uma imagem atual para uma codificação de vídeo de alta eficiência (hevc). a imagem colocalizada é identificada por acessar sintaxe que pode incluir um índice para uma lista0 e uma lista1, um número de conjunto de imagem de referência indicando o número de imagens em lista0 e lista1, e um sinalizador indicando se a imagem colocalizada é em lista0 ou lista1. o sistema pode ainda usar tipo de fatia para determinar se ambas lista0 e lista1 devem ser acessadas.
