Abstract: Systems and methods are provided for identifying important video frames and segments in multimedia content such as a segmented compressed domain video. Video frames in a segment are analyzed to determine intensity, contrast, and motion values for the frames and their segments. The values among frames and segments are compared to identify one or more video segments likely to be important to a viewer. The systems and methods may additionally be augmented with audio data other characteristics associated with the video frames and segments analyzed.

Abstract: A method and device for editing a media file comprising input video frames. The editing device comprises a frame analyzer to determine whether the input video frames have the frame characteristics suitable for compressed domain editing or spatial domain editing. For those frames suitable for compressed domain editing, the frame analyzer provides frame data to a compressed domain processor so that video frame data can be modified in the compressed domain. For those frames only suitable for spatial domain editing, the frame analyzer provides frame data to a decoder and then to a spatial domain processor for frame data modification. The modified data at different domains are combined and converted to file format by a file format composer. Moreover, a file format parser is used to separate audio data from video data so that audio data can also be modified, if so desired.
