Abstract

método implementado por decodificador, dispositivos de codificação e de decodificação de vídeo, e meio não transitório legível em computador. a presente invenção refere-se a codificação de vídeo; método implementado por decodificador, dispositivos de codificação e de decodificação, e de produto de computador (dispositivos e meio de legível armazenamento). o mecanismo inclui a codificação de um fluxo de bits que compreende um conjunto de parâmetros de vídeo (vps) e uma ou mais subcamadas. uma mensagem de informação suplementar de enriquecimento (sei) do período de buffering (bp) que compreende um máximo de subcamadas menos um (bp_max_sublayers_minus1) de bp também é codificada no fluxo de bits. o bp_max_sublayers_minus1 é definido como um valor em uma faixa de zero a um número máximo de subcamadas indicado no vps. um decodificador de referência hipotético (hrd) é inicializado com base na mensagem sei de bp. um conjunto de testes de conformidade de fluxo de bits é executado nas subcamadas. o fluxo de bits é armazenado para comunicação com um decodificador.
