    摘要: A pair of main-view and sub-view video streams, a graphics stream, and playlist information are recorded on a BD-ROM disc. The sub-view video stream includes metadata arranged in each GOP. The metadata includes a correspondence table associating offset identifiers and offset information. The offset information defines offset control for each picture in a GOP. Offset control is processing to provide a left offset and right offset for the horizontal coordinates in a graphics plane to generate a pair of graphics planes that are respectively combined with main-view and sub-view video planes. The playlist information includes a stream selection table for each playback section. When the stream selection table associates a stream number with a packet identifier of a graphics stream, one of the offset identifiers is further allocated to the stream number.
