Abstract

Systems, methods, and instrumentalities are disclosed for parallel decoding of a layered video stream. A base layer video stream and an enhancement layer video stream may be received. A picture of the base layer video stream may be decoded via a first processing thread. An inter-layer reference picture associated with the base layer video stream may be generated via the first processing thread. The inter-layer reference picture may include one or more motion fields. A picture of the enhancement layer video stream may be decoded via a second thread using the inter-layer reference picture. The first processing thread and the second processing thread may be synchronized such that the decoding of the picture of the enhancement layer video stream is performed after the generation of the inter-layer reference picture.
