RECORD MEDIUM, PLAYBACK UNIT, RECORDING METHOD, INTEGRAL MICROCHIP, PROGRAMME AND PLAYBACK METHOD Russian patent published in 2008 - IPC H04N5/92 H04N7/08 G11B20/10 

FIELD: information technology.

SUBSTANCE: invention belongs to such record medium as the BD-ROM (blue-ray disc read-only memory), particularly to the systems displaying subtitles and interactive content via graphic means. The AVClip stream recorded on a BD-ROM disc is formed by multiplexing the graphic stream with the video stream. The graphic data stream is a succession of PES-packets, which includes PES-packets with graphic data (ODS segments) (Object Definition Segments) and PES-packets with control information (PCS segments) (Presentation Composition Segments). In each ODS segment, the values of DTS-score (decoding time score) and PTS-score (presentation time score) refer to the decoding start and stop moments for respective graphic data. In each PCS-segment, the value of the PTS-score refers to the time moment where the respective decoded graphic data is combined with the video data stream.

EFFECT: creating a record medium that would actualise high level of graphic data resolution without increasing the factory costs.
