Abstract: A method and a system for identifying an operating status of an electrical appliance based on non-intrusive load monitoring are provided. The method includes the following steps. Total power consumption history data of a target field and appliance power consumption history data of target electrical appliances are obtained. The appliance power consumption history data of each target electrical appliance is converted into a binary data set. The total power consumption history data is clustered into cluster samples to obtain first feature data sets, which are then dimensionally reduced into second feature data sets, and a machine learning model is trained by using the second feature data sets and the binary data sets of the target electrical appliances to establish an operation identification model for the target electrical appliances. The operation identification model identifies an operating status of the target electrical appliances according to total power consumption data.

Abstract: A transcoder system for adaptively reducing frame rate is provided, which can change audio-visual stream of a GOP (group of picture). Each picture in the GOP consists of a plurality of macroblocks. The transcoder system includes a switching device, a variable length decoder, a motion vector compensation device, a memory and an encoder/decoder. The motion vector compensation device can compute output motion vectors respectively for the macroblocks in accordance with input picture types, so video data of I-, P- and B-pictures without complete reduced frame-rate transcoding in the prior art can be avoided. Therefore, video transcoding for pictures can be performed completely and quickly to thus reduce required transcoding computation and further increase transcoding speed.
