摘要： According to one aspect, a computerized method and apparatus for generating and presenting search snippets that enable user-directed navigation of the underlying audio/video content. The method involves obtaining metadata associated with discrete media content that satisfies a search query. The metadata identifies a number of content segments and corresponding timing information derived from the underlying media content using one or more automated media processing techniques. Using the timing information identified in the metadata, a search result or “snippet” can be generated that enables a user to arbitrarily select and commence playback of the underlying media content at any of the individual content segments.

摘要： A method for converting a signal from a low voltage domain to a high voltage domain includes receiving an input signal in a low voltage domain, and using the input signal, controlling a first transistor having a first carrier type, a second transistor having a second carrier type different from the first carrier type, and a third transistor having the second carrier type to produce an output voltage at an output terminal. The first transistor is coupled to the output terminal and further coupled to a first voltage corresponding to a first value in a high voltage domain. The second and third transistors are coupled in series between the output terminal and a second voltage corresponding to a second value in the high voltage domain. The output voltage is selected to correspond to either the first voltage or the second voltage based upon the input signal.
