摘要： Systems and methods to enable real-time and near real-time storyboarding on the World Wide Web in addition to a graphical user interface for video parsing and browsing the of the storyboard. Specifically, storyboarding can be accomplished on the World Wide Web by parsing an input video into representative or key frames. These frames then can be posted to a web document, or the like, for subsequent viewing by a user. This allows a video to be distilled down to the essential frames thus eliminating storage and bandwidth problems as well as eliminating the need for a user to view the entirety of the video. Furthermore, the graphical user interface allows a user to visually interact with an input video signal to determine the key or representative frames, or to retrieve video segments associated with already determined key frames. Furthermore, the interface allows manipulation of these frames including, but not limited to, playing of the entire segment represented by that key or significant frame as well as actual determining of the cuts between significant segments.

摘要： Systems and methods for detecting robust fade and dissolve and video sequences. The systems and methods use a two step approach to detect both discontinuous cuts and gradual changes in a video sequence. Specifically, an input video signal is first divided into video segments based on the location of the discontinuous cut. A gradual change detector is then applied to the discontinuous cut segments to determine further cuts based on editing characteristics. By using this two part approach, the systems and methods of this invention can robustly detect scene breaks within a video.

摘要： In one embodiment, a method of streaming media includes partitioning a media stream to be transmitted into a first stream of media segments at a media server. The first stream of the media segments has a first sequence. An index table is generated to identify the first sequence of the first stream of the media segments. The index table is encrypted using a key. A second stream of the media segments is generated. The second stream has a second sequence, which is random relative to the first sequence. The encrypted index table and a transcoded media stream having the second stream of the media segments are transmitted.

摘要： Methods and systems for a multimedia queue management solution that maintaining graceful Quality of Experience (QoE) degradation are provided. The method selects a frame from all weighted queues based on a gradient function indicating a network performance rate change and a distortion rate caused by the frame and its related frames in the queue, and dropping the selected frame and all its related frames, and continues to drop similarly chosen frame until a network performance rate change caused by the dropping frame and its related frames meets a predetermined performance metric. A frame gradient is a distortion rate divided by a network performance rate change caused by the frame and its related frames, and a distortion rate is based on a sum of each individual frame distortion rate when the frame and its related frames are replaced by some other frames derived from remaining frames based on a replacement method.

摘要： A system and method for region-of-interest-based bit-allocation scheme for video coding is provided. A method for encoding an image sequence of inter-frames and intra-frames includes grouping the inter-frames and the intra-frames in at least one group of pictures (GOP), and performing a frame-level bit-allocation to inter-frames and the intra-frames in the GOP. For each frame of the inter-frames and the intra-frames in the GOP, the method also includes partitioning the frame into a plurality of macroblocks, identifying macroblocks in the plurality of macroblocks as having regions of interest (ROI), and performing a macroblock level bit-allocation for the frame based on macroblocks identified as having ROI. The method further includes encoding the image sequence based on the bit-allocations, thereby producing an encoded image sequence, and outputting the encoded image sequence.
