    摘要： Methods, systems, and computer program products for the generation of multiple layers of scaled encoded video data compatible with the HEVC standard. Residue from prediction processing may be transformed into coefficients in the frequency domain. The coefficients may then be sampled to create a layer of encoded data. The coefficients may be sampled in different ways to create multiple respective layers. The layers may then be multiplexed and sent to a decoder. There, one or more of the layers may be chosen. The choice of certain layer(s) may be dependent on the desired attributes of the resulting video. A certain level of video quality, frame rate, resolution, and/or bit depth may be desired, for example. The coefficients in the chosen layers may then be assembled to create a version of the residue to be used in video decoding.

    摘要翻译： 用于生成与HEVC标准兼容的多层缩放编码视频数据的方法，系统和计算机程序产品。 可以将来自预测处理的残差变换为频域中的系数。 然后可以对系数进行采样以创建编码数据层。 可以以不同的方式对系数进行采样以创建多个相应的层。 然后可以将这些层复用并发送到解码器。 在那里，可以选择一个或多个层。 某些层的选择可以取决于所得到的视频的期望属性。 例如，可能需要某种级别的视频质量，帧速率，分辨率和/或比特深度。 然后可以组合所选择的层中的系数以创建要在视频解码中使用的残余的版本。
