<p>Systems, methods and instrumentalities are provided to implement motion information signaling for scalable video coding. A video coding device may generate a video bitstream comprising a plurality of base layer pictures and a plurality of corresponding enhancement layer pictures. The video coding device may identify a prediction unit (PU) of one of the enhancement layer pictures. The video coding device may determine whether the PU uses an inter-layer reference picture of the enhancement layer picture as a reference picture. The video coding device may set motion vector information associated with the inter-layer reference picture of enhancement layer to a value indicative of zero motion, e.g., if the PU uses the inter-layer reference layer picture as the reference picture.</p> |
