SIGNAL PROCESSING METHOD AND APPARATUS FOR THREE-DIMENSIONAL REPRODUCTION OF ADDITIONAL DATA

摘要

FIELD: physics.SUBSTANCE: signal processing method includes extracting three-dimensional (3D) reproduction information from subtitle data. The subtitle data include information on the region in which the subtitles are displayed. The 3D reproduction information includes an offset value which indicates the depth and direction of offset. The offset direction indicates the direction in which the offset value is applied for each of said at least one region.EFFECT: high efficiency of displaying subtitles when reproducing 3D video.4 cl, 30 dwg, 35 tbl
