FIELD: technology for encoding data to provide for slide show with possible paging.
SUBSTANCE: decoding device has decoder of main stream of image data, subject for reproduction in slide show with possible paging; decoder of sub-audio data, attached to image data; counter of system temporal synchronization of main flow, which provides series of system temporal synchronization for controlling time of decoding of packet data of main flow for decoder of main flow, and counter of sub-audio system temporal synchronization, which provides system temporal synchronization series for controlling time of decoding of packet sub-audio data for sub-audio decoder.
EFFECT: possible smooth reproduction of sub-audio data, even when user selects direct or reverse viewing in the middle of reproduction of data of fixed image with sub-audio data added in slide show with possible paging.
