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.

Abstract: A 3D video system for transmission of 3D data towards various types of 3D displays is described. A 3D source device (40) provides a three dimensional [3D] video signal (41) to a 3D destination device (50). The 3D destination device receives the 3D video signal, and has a destination depth processor (52) for providing a destination depth map for enabling warping of views for the 3D display. The 3D source device generates depth signaling data, which represents depth processing conditions for adapting, to the 3D display, the destination depth map or the warping of views. The 3D video signal contains the depth signaling data. The destination depth processor adapts, to the 3D display, the destination depth map or the warping of views in dependence on the depth signaling data. The depth signaling data enables the rendering process to get better results out of the depth data for the actual 3D display.
