Abstract
A recorder creating an encoded data stream comprising an encoded video stream and an encoded graphics stream, the video stream comprising an encoded 3D (three-dimensional) video object, and the graphics stream comprising at least a first encoded segment and a second encoded segment, the first segment comprising 2D (two-dimensional) graphics data and the second segment comprises a depth map for the 2D graphics data. A graphics decoder decoding the first and second encoded segments to form respective first and second decoded sequences. Outputting the first and second decoded sequences separately to a 3D display unit. The 3D display unit combining the first and second decoded sequences and rendering the combination as a 3D graphics image overlaying a 3D video image simultaneously rendered from a decoded 3D video object decoded from the encoded 3D video object.
