1. A method comprising:

  • generating syntax elements indicating an inter-layer dependency structure among three dimensional video (3DV) layers, the syntax elements relating to a syntax structure defining inter-layer dependencies among 3DV layers wherein the inter-layer dependency structure specifies at least one of;

    b) that an inter-layer prediction reference for an occlusion video layer is the 2D video layer;

    c) that an inter-layer prediction reference for an occlusion depth layer is the depth layer; and

    d) that an inter-layer prediction reference for a transparency layer is the 2D video layer;

    identifying, based on the inter-layer dependency structure, an inter-layer prediction reference for a picture from a layer of the 3DV layers; and

    encoding the picture based, at least in part, on the inter-layer prediction reference.
