Abstract

A pair of main-view and sub-view video streams and a graphics stream are recorded on a BD-ROM disc. Metadata is provided in each GOP in the sub-view video stream. The metadata includes offset information. The offset information specifies offset control for a plurality of pictures constituting a GOP. Offset control is to provide a left offset and right offset for the horizontal coordinates in a graphics plane to generate a pair of graphics planes, and to combine them separately with main-view and sub-view video planes. The sub-view video stream is packetized and multiplexed in a transport stream. A header of each TS packet includes a TS priority flag. TS packets containing the metadata have a different value of TS priority flag from TS packets containing sub-view pictures.
