1. Coding device intended to exploit the data from different 3D production means, data relating to a right image and a left image, data relating to depth maps associated with right images and/or left images and/or data relating to occlusion layers, comprising means to generate a stream structured on several levels:
- a level 0 comprising two layers, a base layer containing the video data of the right image and a level 0 enhancement layer containing the video data of the left image, or conversely,a level 1 comprising two enhancement layers, a first level 1 enhancement layer containing a depth map relating to the image of the base layer, a second level 1 enhancement layer containing a depth map relating to the level 0 enhancement layer image,a level 2 comprising a level 2 enhancement layer containing occlusion data relating to the base layer image.
