A three dimensional [3D] video signal (41) is provided for transferring to a 3D destination device (50). Depth metadata is determined indicative of depths occurring in the 3D video data, which depth metadata includes a near value indicative of depths of video data nearest to a user. The 3D video signal, which comprises the 3D video data, now also includes the depth metadata. The 3D destination device (50) is enabled to retrieve the depth metadata, to provide auxiliary data, and to position the auxiliary data at an auxiliary depth in dependence of the retrieved metadata for displaying the auxiliary data in combination with the 3D video data such that obscuring the auxiliary data by said nearest video data, and/or disturbing effects at the boundary of the auxiliary data, is avoided. |
