Abstract

SUPORTE DE CAMADA DE BASE NÃO-HEVC EM EXTENSÕES MULTICAMADAS DE HEVC. A presente invenção se refere a um aparelho configurado para decodificar informações de vídeo que inclui uma memória e um processador em comunicação com a memória. A memória é configurada para uma memória configurada para armazenar informações de vídeo associadas com fluxo de bits. O aparelho inclui ainda um processador em comunicação com a memória, o processador configurado para determinar que uma camada de referência não está incluída no fluxo de bits e para receber, a partir de uma fonte externa, uma imagem de camada de base decodificada. O processador é ainda configurado para receber, a partir da fonte externa, uma primeira indicação de que a imagem é uma imagem de ponto de acesso intra-aleatório (IRAP). O processador também é configurado para receber uma segunda indicação sobre se a imagem é uma dentre uma imagem de atualização de decodificador instantânea (IDR), uma imagem de acesso aleatório limpa (CRA) ou uma imagem um acesso link quebrado (BLA); e para decodificar as informações de vídeo com base, pelo menos em parte, nas primeira e segunda indicações.
