    • The invention provides a meter socket assembly (10) for a watt-hour meter with removable and changeable meter jaws. The meter socket assembly comprises a meter base (100), at least one meter jaw assembly (200, 200', 300, 300') with an optional 5th terminal device (500). The assemblies are snapped on to the meter base and locked into the meter base. Any meter jaw assembly in the meter socket device is able to be removed or changed by simply loosening a connection nut and then releasing the meter jaw assembly by pressing a cross locking tab. The meter base, mounted to enclosure of a meter socket device or a meter socket module, is also changeable. The meter socket device is suitable for a meter socket with line and load busing connections, especially modular metering devices.

    • To estimate content complexity of a video, energy of prediction residuals is calculated. The prediction residuals are usually smaller when the video is less complex and more predictable. Scales of prediction residuals also depend on encoding configurations, for example, I pictures usually have larger prediction residuals than P and B pictures even when the contents are very similar and thus have similar perceived content complexity. To more closely reflect the content complexity, alignment scaling factors are estimated for different encoding configurations. Based on the energy of prediction residuals and alignment scaling factors, an overall content unpredictability parameter can be estimated to compute a compression distortion factor for the video. The compression distortion factor, combined with slicing and freezing distortion factors, can be used to estimate a video quality metric for the video.
    • 为了估计视频的内容复杂度,计算预测残差的能量。 当视频不太复杂和更可预测时,预测残差通常较小。 预测残差的尺度也取决于编码配置,例如,即使当内容非常相似并且因此具有相似的感知内容复杂性时,I画面通常具有比P和B画面更大的预测残差。 为了更紧密地反映内容复杂性,针对不同的编码配置估计对齐缩放因子。 基于预测残差和对准缩放因子的能量,可以估计总体内容不可预测性参数以计算视频的压缩失真因子。 压缩失真因子,结合切片和冻结失真因子,可用于估计视频的视频质量度量。
