Abstract: A voltage control method for a power converter includes: acquiring a current of a first primary side winding of a transformer circuit of the power converter; integrating the acquired current to obtain an average voltage; comparing the average voltage with a reflected voltage associated with a current of a secondary side winding of the transformer circuit; and adjusting a duty cycle of a switch of the power converter based on an obtained comparison result for adjustment of an output voltage of the power converter.

Abstract: An electric power converting device includes a rectifier, a flyback voltage converter and a non-isolated voltage regulator. The rectifier is for converting an alternating current (AC) signal received from an AC power source into a direct current (DC) signal. The flyback voltage converter is electrically connected to the rectifier for transforming voltage of the DC signal from the rectifier to output a regulated DC signal. The non-isolated voltage regulator is electrically connected to the flyback voltage converter for reducing a voltage ripple of the regulated DC signal from the flyback voltage converter and for outputting an output voltage to a load.

Abstract: A video decoding and transcoding method and system, which decodes, displays and transcodes a video stream. When a previous frame is completely decoded, a decoding procedure checks whether a frame buffer assigned is usable. When the frame buffer is usable, a current frame is decoded to produce a decoded frame and temporarily store the decoded frame in the frame buffer, and a frame flag corresponding to the frame buffer is set. When a previous field is completely displayed, a displaying procedure checks whether the frame buffer temporarily stores the decoded frame. When the frame buffer temporarily stores the decoded frame, the decoded frame is read and displayed. When the previous frame is completely decoded, a transcoding procedure checks whether the frame buffer temporarily stores the decoded frame. When the frame buffer temporarily stores the decoded frame, the decoded frame is read and transcoded.

This method calculates and compares the pixel means and means of absolutely difference of a plurality of pixel blocks in a macroblock to achieve the purpose of detecting if there is an object edge or flat area in a macroblock. In the meantime, the image structure of macroblock is analyzed and classified and its related messages are used for bit rate control, such that the visual effect of the compressed image can be appropriately enhanced.

Abstract: A mode decision system and method for motion vector fine search. Each macroblock in a frame has a pre-determined clock number. The system includes a first subtractor, an operation level generator and a determinator. The first subtractor has a first input terminal to receive a clock number and a second input terminal to receive the pre-determined clock number in order to subtract the clock number from the pre-determined clock number and accordingly generate a clock difference. The operation level generator is connected to the first subtractor in order to generate an operation level based on the clock difference. The determinator selects one or more modes in accordance with the operation level and accordingly performs the fine search on the macroblock.
