Abstract

1/1 resumo “decodificação e codificação de imagens de uma sequência de vídeo” a presente invenção refere-se a modalidades que reduzem o atraso na saída de imagens através da determinação, após uma imagem atual ter sido decodificada e armazenada em um armazenador temporário de imagens decodificadas, dpb, (125, 225, 325, 425, 525, 625), um número de imagens no dpb (125, 225, 325, 425, 525, 625) que estão marcadas como que precisam ser emitidas. esse número é comparado, após uma imagem atual ter sido decodificada e armazenada no dpb (125, 225, 325, 425, 525, 625), com um valor derivado de ao menos um elemento de sintaxe presente ou a estar presente em um fluxo de bits (10) representando imagens de uma sequência de vídeo. se esse número é maior do que o valor, uma imagem, que é a primeira imagem em ordem de saída, das imagens no dpb (125, 225, 325, 425, 525, 625) que estão marcadas como que precisam ser emitidas, é preferencialmente emitida e marcada como que não precisa ser emitida.
