Abstract

SINALIZAÇÃO DE SUBIMAGEM NA CODIFICAÇÃO DE VÍDEO. Um exemplo de dispositivo para codificar dados de vídeo inclui memória configurada para armazenar os dados de vídeo e um ou mais processadores implementados no conjunto de circuitos e acoplados comunicativamente à memória. Os um ou mais processadores são configurados para determinar se um conjunto de parâmetros de sequência dos dados de vídeo refere-se a um conjunto de parâmetros de vídeo. Com base no conjunto de parâmetros de sequência que não se refere ao conjunto de parâmetros de vídeo, os um ou mais processadores são configurados para determinar um valor de um primeiro elemento de sintaxe para ser indicativo de uma estrutura de camada de perfil de camada sendo sinalizada no conjunto de parâmetros de sequência e codifica os dados de vídeo com base na estrutura de camada de perfil de camada.
