    摘要： Systems, methods, and instrumentalities are provided to implement video coding system (VCS). The VCS may be configured to receive a video signal, which may include one or more layers (e.g., a base layer (BL) and/or one or more enhancement layers (ELs)). The VCS may be configured to process a BL picture into an inter-layer reference (ILR) picture, e.g., using picture level inter-layer prediction process. The VCS may be configured to select one or both of the processed ILR picture or an enhancement layer (EL) reference picture. The selected reference picture(s) may comprise one of the EL reference picture, or the ILR picture. The VCS may be configured to predict a current EL picture using one or more of the selected ILR picture or the EL reference picture. The VCS may be configured to store the processed ILR picture in an EL decoded picture buffer (DPB).

    摘要： Methods, systems, and instrumentalities are described to implement single loop decoding, A video decoding device (VDD) may receive a video bitstream, which may include one or more bitstreams (e.g., base layer bitstream, enhanced layer bitstream, etc.) The VDD may generate a hybrid inter-layer reference (H-ILR) picture. The H-ILR picture may be generated based on one or more inputs including, for example, a first layer motion information, a processed (e.g., upsampled) first layer residue signal, a second layer texture information, etc. The first layer motion information may be derived from a compressed first layer motion field or an uncompressed first layer motion field. An H-ILR block of the H-ILR picture may be reconstructed by deriving motion information of the H-ILR block from one or more neighboring H-ILR blocks in the H-ILR picture, for example, when the neighboring blocks are inter-coded.

    摘要翻译： 描述了方法，系统和工具来实现单循环解码，视频解码设备（VDD）可以接收视频比特流，其可以包括一个或多个比特流（例如，基本层比特流，增强层比特流等）。 可以产生混合层间参考（H-ILR）图像。 可以基于包括例如第一层运动信息，经处理（例如，上采样）第一层残差信号，第二层纹理信息等的一个或多个输入来生成H-ILR图像。第一层运动信息 可以从压缩的第一层运动场或未压缩的第一层运动场导出。 H-ILR图像的H-ILR块可以通过从H-ILR图像中的一个或多个相邻H-ILR块导出H-ILR块的运动信息来重构，例如，当相邻块是inter- 编码。
