Abstract

formatos de arquivo e análise e codificação de dados de vídeo são definidos para promover acessibilidade aleatória mais eficiente de dados de vídeo codificados. restrições podem ser impostas na colocação de conjuntos de parâmetros e a definição de amostras de sincronização em arquivos de vídeo. dados de conjunto de parâmetros para dados de vídeo podem ser codificados, para uma amostra não sincronizada, apenas na entrada de amostra para a amostra, a amostra, uma amostra anterior na ordem de decodificação que uma amostra de sincronização, ou em uma amostra ocorrendo na ordem de decodificação entre a amostra e amostra anterior na ordem de decodificação que é uma amostra de sincronização.
