A method and system generates and compares fingerprints for videos in a video library. The video fingerprints provide a compact representation of the temporal locations of discontinuities in the video that can be used to quickly and efficiently identify video content. Discontinuities can be, for example, shot boundaries in the video frame sequence or silent points in the audio stream. Because the fingerprints are based on structural discontinuity characteristics rather than exact bit sequences, visual content of videos can be effectively compared even when there are small differences between the videos in compression factors, source resolutions, start and stop times, frame rates, and so on. Comparison of video fingerprints can be used, for example, to search for and remove copyright protected videos from a video library. Furthermore, duplicate videos can be detected and discarded in order to preserve storage space.

In a method and system for creating an extensible media player, a multimedia player application is instantiated on a client system. A timeline to be played by the instantiated multimedia player application is transmitted to the client system. One or more modules and one or more layouts are dynamically selected and retrieved for the timeline. The modules contain application logic to extend a functionality of the multimedia player application. The layouts contain logic to control an aspect of a presentation of the multimedia player application and the modules. The timeline, the modules, and the layouts are loaded into the multimedia player application. The loaded modules are verified to determine if any module is blocking the timeline from playing. If a module is blocking the timeline from playing, the blocking module is executed and playback of the timeline is stopped until execution is complete. If no module is blocking the timeline, the timeline begins playing back. Each subsequent module and each loaded layout is executed at a predetermined time during playback of the timeline. As each module is executed, the module is checked to determine whether the module is blocking the timeline from playing. If the module is blocking the timeline, playback of the timeline is stopped or paused until execution of the module is complete.

A control circuit is provided for a separately excited DC/DC converter which directly monitors output voltage to detect a short-circuit state, and performs overcurrent protection. A switching controller of the control circuit controls a switching operation of a switching transistor of the separately excited DC/DC converter. A voltage comparator compares the output voltage and a threshold voltage, to detect the short-circuit state. After a predetermined start-up time has elapsed after beginning start-up of the separately excited DC/DC converter, when the voltage comparator detects the short-circuit state, the switching controller halts the switching operation of the switching transistor, and makes detection of the short-circuit state by the voltage comparator non-operative before elapse of the start-up time. After detecting the short-circuit state and halting the switching operation of the switching transistor for a predetermined halt time, the switching controller begins start-up of the separately excited DC/DC converter once again.
