Abstract: 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.

Abstract: A hybrid transmission/auto-conversion 3D format and scheme for transmission of 3D data towards various types of 3D displays is described. In the decoder (20) a stereo-to-depth convertor (24) generates a depth map. In the 3D video signal additional depth information called depth helper data (DH-bitstr) is sparsely transmitted both in time (partial depths in time) and/or spatially (partial depth within the frames). A depth switcher (25) selects the partial depths based on an explicit or implicit mechanism for indicating when these are to be used or when the depths must be automatically generated locally. Advantageously disturbing depth errors due to said stereo-to-depth convertor are reduced by the depth helper data.
