    摘要： Functionality is described for forming a summary representation of a video item to help a user decide whether to obtain a full version of the video item. The functionality operates by: (a) receiving a video item; (b) dividing the video item into a plurality of segments; (c) extracting at least one key frame from each of the plurality of segments to form a plurality of key frames; and (d) organizing the video segments into one or more groups corresponding to one or more respective scenes based on the plurality of key frames, to thereby form the representation of the video item. The functionality can be used to communicate search results to a user, to provide a sample of the video item in a message, etc.

    摘要： A control circuit, a control method, and a power supply device are provided. The control circuit includes an obtaining sub-circuit, adapted to obtain a voltage signal from a reverse surge current when the reverse surge current appears on a primary side of a switch power circuit of a synchronous rectification circuit; a maintaining sub-circuit, adapted to continuously output a first control signal in a preset first time period when the voltage signal is greater than a preset first voltage threshold; and a control sub-circuit, adapted to control and switch off switch tubes of the secondary side of the switch power circuit of the synchronous rectification circuit according to the first control signal. Thus, a reverse current surge of the switch power circuit of the synchronous rectification circuit can be effectively suppressed, and the safety of a switch power supply of the synchronous rectification circuit can be effectively protected.
