Patent number: 10056823Abstract: A protection circuit applied to an alternating current (AC) power source includes a sample-and-hold unit, a detection unit, and a discharge signal generation unit. The sample-and-hold unit samples a peak value of a direct current (DC) voltage during each period of a corresponding AC voltage, wherein the AC power source provides the AC voltage. The detection unit generates a detection signal when the DC voltage crosses a reference voltage corresponding to the peak value. The discharge signal generation unit generates a count signal when the discharge signal generation unit does not receive the detection signal within a predetermined time of a period of the AC voltage, accumulates the count signal, and generates a discharge signal to a discharge unit when a number of accumulated count signals is greater than a predetermined value, wherein the discharge unit discharges an X capacitor according to the discharge signal.Type: GrantFiled: February 1, 2016Date of Patent: August 21, 2018Assignee: Leadtrend Technology Corp.Inventors: Ming-Chang Tsou, Meng-Jen Tsai, Yu-Kun Lin

Patent number: 9532074Abstract: A method and apparatus for encoding of video data incorporating loop filtering are disclosed. The method and apparatus according to an embodiment of the present invention determines an initial loop filter level for a frame of the video data according to quality setting of the frame. The information associated with the initial loop filter level is incorporated in the bitstream corresponding to compressed video data. The loop filtering is applied to a macroblock without the need to wait for the whole frame reconstruction to complete. In another embodiment according to the present invention, the initial loop filter level may be refined according to stability associated with the frame.
