摘要： Embodiments of the present invention provide a mobile device comprising a core phone with a detachable primary device. The core phone transfers an incoming call alert to the detached primary device by synchronizing the display frame buffer of the core phone with the display frame buffer associated with the detached primary device. A plurality of remote secondary devices can be paired with the core phone on request by said secondary devices to transfer an incoming call alert to said plurality of secondary devices and establish a connection after authorization with said detached primary device. The detachable primary device is usable by pairing with the core phone when the core phone is not used directly but remains in the vicinity. Important data in the primary device is synchronized with the core phone to avoid data loss when the primary device is accidentally dropped or lost or damaged.

摘要： A method for watermarking of video content is provided. An averaged scene image is computed for each scene of video content by performing averaging of frames present in each scene of video content. For each averaged scene image a set of random numbers are generated using a secret key to identify pixels at random locations of the averaged scene image. The secret key is associated with a watermark pattern corresponding to each averaged scene image. The identified pixels in each averaged scene image are mapped to each pixel of corresponding watermark pattern to obtain respective mapped pixels. Using respective mapped pixels, values of verification information are fetched and assigned using predetermined rules. The values of verification information are arranged to obtain first visual cryptographic share of watermark pattern for each averaged scene image.

摘要： A method, system and computer-readable media for detecting scene changes in a video that includes providing by one or more computing devices a plurality of passes through the video where a plurality of detected scenes from a first pass in a conventional method are identified and a second pass through the detected scenes are provided by the computing device. A plurality of scene boundary differences corresponding to the detected scenes, a fixed average, and a varying average are computed by the computing device. The scene boundary difference is compared with the fixed average and the varying average and if the scene boundary difference is less than the fixed average and the varying average, the detected scenes are combined else the detected scene being an abrupt scene change is determined. The steps of computing a varying average to combining the detected scenes are repeated by the computing device.
