FIELD: information technologies.
SUBSTANCE: device for reproducing the data recorded on record medium includes recording/reading head, local memory and decoder. Recording/reading head reads the main data recorded on the record medium. Local memory stores sub-data associated with the main data. Sub-data can include flows of interactive graphics or flows of text sub-titles. Decoder decodes the main data and sub-data by using PlayList. PlayList file includes the main sequence and sub-sequence. The main sequence includes PlayItem for reproducing the main data. Sub-sequence consists of at least one SubPlayItem associated with PlayItem in order to reproduce sub-data together with the main data. In addition, PlayList file includes the information on the type of sub-sequence which specifies whether SubPlayItem included in the sub-sequence is synchronised with PlayIem.
EFFECT: possibility of reproducing the data recorded on record medium and the data stored in local memory.
