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).

摘要翻译： 提供了系统，方法和手段来实现视频编码系统（VCS）。 VCS可以被配置为接收可以包括一个或多个层（例如，基本层（BL）和/或一个或多个增强层（EL））的视频信号。 VCS可以被配置为将BL图像处理为层间参考（ILR）图像，例如使用图像级间层预测处理。 VCS可以被配置为选择处理的ILR图像或增强层（EL）参考图片中的一个或两个。 所选择的参考图片可以包括EL参考图片或ILR图片之一。 VCS可以被配置为使用所选择的ILR图像或EL参考图像中的一个或多个来预测当前EL图像。 VCS可以被配置为将经处理的ILR图像存储在EL解码图像缓冲器（DPB）中。
