  • Patent number: 10451294
    Abstract: Smart hot water heater control can be improved by departing from the conventional approach of monitoring hot water demand at a single point (i.e., the water heater output). Instead, hot water demand is monitored at each location in the building where hot water is used. With this approach, the controller can provide hot water at a temperature suitable for the intended use, e.g., warm water for a bath or shower, and much hotter water for a dishwasher. This advantageously avoids inefficiency due to mixing hot and cold water at a tap to provide temperature control.

  • Patent number: 10326995
    Abstract: System and method embodiments are provided for achieving improved View Synthesis Distortion (VSD) calculation and more accurate distortion estimation of encoded video frames. An embodiment method includes obtaining a depth map value for a video frame and determining a weighting factor for depth distortion in accordance with the depth map value. The weighting factor maps a pixel range of the depth map value to an output function having higher values for closer image objects and lower values for farther image objects. The VSD for the video frame is then calculated as a function of absolute horizontal texture gradients weighted by a depth distortion value and the weighting factor determined in accordance with the depth map value.

  • Patent number: 10085028
    Abstract: A method for reducing a computational load in high efficiency video coding includes generating a full rate distortion calculation list of selected intra coding modes where the intra coding modes including intra prediction modes and depth modeling modes. A rate distortion cost is determined, with a segment-wise depth coding mode being disabled, for each intra prediction mode in the full rate distortion calculation list and a smallest rate distortion cost intra prediction mode is selected. A rate distortion cost for a particular intra prediction mode is calculated with the segment-wise depth coding mode enabled. After comparison, one of the particular intra prediction mode and the smallest rate distortion cost intra prediction mode having the smallest rate distortion cost is applied to a prediction unit.

  • Patent number: 10057586
    Abstract: Depth based block partitioning in high efficiency video coding is provided by partitioning a video image block into different partitions using a binary segmentation mask. A determination is made whether to filter pixels at a boundary between the partitions. A particular pixel is not filtered in response to each adjacent pixel in vertical and horizontal planes in relation to the particular pixel having a same value. The particular pixel is filtered in response to any adjacent pixel in the vertical and horizontal planes in relation to the particular pixel having a different value than any other adjacent pixel in the vertical and horizontal planes in relation to the particular pixel. Pixels are filtered pursuant to a filtering process in response to a filtering determination.
