a media presentation device that provides an aural and/or visual representation of a media file being browsed; and
a feature indicator that provides information related to a confidence score for at least one selected media feature, the confidence score being related to a presence of a corresponding selected media feature in the media file;

Abstract
A media browser, graphical user interface and method for browsing a media file wherein a user selects at least one feature in a media file and is provided with information regarding the existence of the selected feature in the media file. Based on the information, the user can identify and playback portions of interest in a media file. Features in a media file, such as a speaker'"'"'s identity, applause, silence, motion, or video cuts, are preferably automatically time-wise evaluated in the media file using known methods. Metadata generated based on the time-wise feature evaluation are preferably mapped to confidence score values that represent a probability of a corresponding feature'"'"'s existence in the media file. Confidence score information is preferably presented graphically to a user as part of a graphical user interface, and is used to interactively browse the media file.
