Abstract
1/1 resumo codificação e decodificação de sequências de vídeo compreendendo conjuntos de imagens de referência a presente invenção refere-se a um método (1000) de codificação de uma sequência de vídeos compreendendo conjuntos de imagens de referência (rpss). o método compreende dispor (1101) os rpss em ordem de transmissão em uma estrutura de dados, tal como um conjunto de parâmetros de sequência (sps), determinar (1003) se a transmissão explícita de rps é usada para um rps de uma imagem atual da sequência de vídeo, e codificar (1004) a informação que indica um rps compreendido na estrutura de dados a ser usado para predizer o rps da imagem atual, tal como delta_idx_minus1, somente se a transmissão explícita de rps for usada. transmitir delta_idx_minus1 somente se a transmissão explícita de rps for usada, e interpretar delta_idx_minus1 como sendo igual a zero, caso contrário, uma taxa de bits reduzida é aplicada. ademais, um método de decodificar uma sequência de vídeo compreendendo rpss, correspondentes a programas de computador e produtos de programas de computador, bem como codificadores e decodificadores correspondentes são fornecidos.
