  • Patent number: 10904577
    Abstract: A video compression system includes a video encoder and a bitstream processing circuit. The video encoder is hardware that performs hardware video encoding upon frames to generate a first bitstream. The first bitstream is output from an entropy encoding circuit of the video encoder. The bitstream processing circuit performs a bitstream post-processing operation upon the first bitstream to produce a second bitstream that is different from the first bitstream, and outputs the second bitstream as a compression output of the frames.

  • Patent number: 10056823
    Abstract: 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.

  • Patent number: 9532074
    Abstract: 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. In yet another embodiment according to the present invention, the method may include determining whether segment mode is on or off and determining a frame-level or segment-level initial loop filter level accordingly.
