Abstract: A method and apparatus of hiding identification data in visual media. When image or video data is received, frequency masking is performed to divide the image or video data into blocks of smooth regions and blocks of non-smooth regions and to obtain preliminary just-noticeable-difference. Edge detection is performed to divide the non-smooth region of the image or video data into texture blocks and edge blocks. Then blocks of regions that are substantially proximate to blocks of smooth regions of the image or video data are determined. The image or video data is then adjusted by applying different strength of watermark in association with the type of each block.

Abstract: In accordance with an embodiment of the present invention, a method for inserting secondary content into a media stream includes dividing the media stream having a plurality of frames into a plurality of shots at a processor. The method further includes grouping consecutive shots from the plurality of shots into a plurality of scenes. A first list of insertion points is generated for introducing the secondary content. The insertion points of the first list are boundaries between consecutive scenes in the plurality of scenes. An average insertion point saliency of the media stream is generated at the insertion points in the first list. A second list of insertion points is then generated. The insertion points in the second list are arranged to maximize a function of the average insertion point saliency and a distance between each insertion point in the second list with other insertion points in the second list.

Abstract: 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.

Abstract: The media player employs an operating system that supports a virtual machine into which auto-run playback programs may be loaded and run. The auto run playback program is stored on the media containing the program content, such as on an optical disc medium. When the medium is inserted in the player, the auto run playback program automatically launches and is thereafter used to access playback the media content. Support for legacy media is provided to allow the player to playback compact discs and DVD discs that were manufactured without the auto run playback program.
