<p>3D video can be transmitted in a legacy 2D video format by conveying 3rd dimension parameters within a steganographic channel of the perceptual video signal, e.g., DCT coefficients, video samples (luminance, chrominance values), etc. The 3rd dimension parameters can be coded as depth values, disparity, displacement, difference, or parallax values, including depth that is converted into X-Y shifts for adjustment to motion vectors in coded video sequence. To limit the amount of information for the steganographic channel, the 3rd dimension information can be quantized relative to the depth from viewer and other prioritization parameters that limit the need for 3rd dimension information to only aspects of the scene that are deemed important to create a desired 3D effect.</p> |
