    摘要: A video coding device may identify a network abstraction layer (NAL) unit. The video coding device may determine whether the NAL unit includes an active parameter set for a current layer. When the NAL unit includes the active parameter set for the current layer, the video coding device may set an NAL unit header layer identifier associated with the NAL unit to at least one of: zero, a value indicative of the current layer, or a value indicative of a reference layer of the current layer. The NAL unit may be a picture parameter set (PPS) NAL unit. The NAL unit may be a sequence parameter set (SPS) NAL unit.

    摘要: Systems, methods, and instrumentalities are disclosed for reference picture set mapping for scalable video coding. A device may receive an encoded scalable video stream comprising a base layer video stream and an enhancement layer video stream. The base layer video stream and the enhancement layer video streams may be encoded according to different video codecs. For example, the base layer video stream may be encoded according to H.264/AVC and the enhancement layer may be encoded according to HEVC. The enhancement layer video stream may include inter-layer prediction information. The inter-layer prediction information may include information relating to the base layer coding structure. The inter-layer prediction information may identify one or more reference pictures available in a base layer decoded picture buffer (DPB). A decoder may use the inter-layer prediction information to decode the enhancement layer video stream.
