Abstract

decodificador de referência hipotético para v-pcc. é descrito um mecanismo de codificação de vídeo. o mecanismo inclui codificar uma sequência de componentes de compressão de nuvem de pontos (pcc) em um fluxo de bits. uma mensagem de informação sobre aprimoramento suplementar (sei) do período de armazenamento em buffer também é codificada no fluxo de bits. um decodificador de referência hipotético (hrd) é inicializado em uma unidade de acesso (au) atlas codificada associada à mensagem sei do período de armazenamento em buffer. uma verificação de conformidade pelo hrd do fluxo de bits é realizada começando na au atlas codificada. o fluxo de bits é armazenado para comunicação com um decodificador.
