Abstract
The present invention relates to a method in a graphics system for creating a graphics stream allowing to form a three-dimensional graphics data, the graphics stream consisting of segments. The graphics stream is divided into at least a first segment and a second segment, the first segment comprises two-dimensional graphics data and the second segment comprises a depth map for the two-dimensional graphics data. The graphics stream can be decoded by a decoder to form two data sequences to be output separately to a display device for rendering a three-dimensional subtitle or graphics image for a three-dimensional video image.
