Abstract

MéTODO E APARELHO PARA REPRODUZIR DADOS GRAVADOS EM MEIO DE GRAVAçãO Um aparelho para reproduzir dados gravados em um meio de gravação que contém uma unidade fonocaptora, um armazenamento local e um decodificador. A unidade fonocaptora lê os dados principais gravados no meio de gravação e o armazenamento local armazena os subdados associados aos dados principais. Os subdados podem conter fluxos de gráficos interativos ou fluxos de legendas de texto, O decodificador decodifica os dados principais e os subdados utilizando uma PlayList que contém um caminho principal e um subcaminho. O caminho principal contém um PlayItem para realizar o playback dos dados principais e o subcaminho contém pelo menos um SubPlayItem associado ao PlayItem para realizar o playback dos subdados associados ao play-back dos dados principais. O Arquivo de PlayList também contém informações do tipo de subcaminho que indicam se o SubPlayItem contido no subcaminho está sincronizado com o PlayItem.METHOD AND APPLIANCE FOR PLAYING DATA RECORDED BY RECORDING A device for playing back data recorded on a recording medium that contains a recording unit, local storage and a decoder. The recorder unit reads the master data written to the recording medium and local storage stores the subdata associated with the master data. Subdata can contain interactive graphic streams or text subtitle streams. The decoder decodes the master data and the subdata using a PlayList that contains a main path and a subpath. The main path contains a PlayItem for playback of the master data and the subpath contains at least one SubPlayItem associated with the PlayItem to playback the subdata associated with the master data playback. The PlayList File also contains subpath type information that indicates whether the SubPlayItem contained in the subpath is synchronized with PlayItem.
