摘要： PURPOSE: To execute security operation by providing a signalizing processor with two input ports for receiving a data block and a signalizing key, an output port for a signalized data block and a reference table. CONSTITUTION: In order to eliminate a complementarity characteristics to deteriorate communication security, an external function having no complementarity is applied to a data signalizing standard DES processor. A non-linear function f1 is applied to a data stream X by a reference table or digital circuit 20. A non-linear function f2 is applied to a signalizing key K through a reference table or circuit 22. A synthetic data stream X' and a signalizing key K' are processed by a processor 10 and the data stream X' is signalized and outputted through a line 15. A non-linear function f3 is applied to the signalized output through a reference table or a digital circuit 24. Thereby a final output Y' can be obtained on a line 16. Thus security operation is executed and the intensity of ciphering is not reduced.

摘要： A method for DTCP to HLS conversion is provided that starts with a standard DTCP Protected Content Packet (PCP) structure. The PCP payload data is chunked at defined chunk boundaries. Each chunk is then appended with a pad to be compatible with HLS. An HLS playlist is then provided using the PCP header with identification of the chunks and a keytag. The chunk is encrypted with a DTCP key calculated by the DTCP standard using: (a) copy control bits; (b) a nonce, and (c) an exchange key ID. Relevant PCP header fields are provided in the keytag for the HLS playlist supporting the transaction that enables calculation of the DTCP content key to enable later decryption of the chunks. The system further provides a revised HLS GET for DLNA to enable trick play seek operations to be performed on the converted HLS.

摘要： The power of analytical modeling is added to existing methods for specifying policies. Generally speaking, humans use their knowledge and experience to draft policies at a relatively high level. These policies then incorporate analytical models which provide the intelligence on how to most effectively apply the high-level policy to a particular situation. When a policy is invoked, the analytical model provides up-to-date intelligence at a level of completeness and refinement not possible with previous techniques. As a result, fewer policies need to be drafted, and those few need to be updated less frequently than in previous schemes. Rather than updating the policy itself, the analytical model is automatically updated whenever new data are fed into it. As the analytical model incorporates new observational data, it grows more powerful and thus automatically increases the effectiveness of the high-level policy.

摘要： A statistical multiplexer (statmux) system for encoding multiple channels of digital television data is provided with improved algorithms for determining bitrate for encoding and decoding to account for signal complexity, including accounting for film mode and GOP structural changes. In film mode when the lower frame per second rate for film mode is identified, rather than faster rate SD or HD modes, instead of determining bit rate from viewing the next picture in the look ahead buffer (LAB), the system looks at a start time stamp for specific data in the LAB. Accounting for GOP structural changes includes identifying the number of pictures (N) between I type pictures in data provided to an encoder and the number of pictures (M) between P type pictures, rather than using a fixed number for N and M.

摘要： In embodiments of live television playback optimizations, streaming video content is received (502) for distribution to a client device (104) that is implemented to playback a video content stream for display. The video content stream is associated with a content manifest file (402) that identifies video segments of the video content stream. An input can be received (504) from the client device (104) to switch from the video content stream to a new video content stream, and video segments of the new video content stream are buffered (508). A new content manifest file (408) that correlates to the buffered video segments of the new video content stream is generated (510). The new content manifest file (408) can then be published (512) to the client device (104) to indicate that a minimum of buffered video segments have been buffered for distribution to the client device (104) before the minimum of buffered video segments have been buffered.

摘要： A method and apparatus for image processing a lens-distorted image (e.g., a fisheye image) is provided. The method includes partitioning coordinate points in a selected output image into tiles. The output image is an undistorted rendition of a subset of the lens-distorted image. Coordinate points on a border of the tiles in the output image are selected. For each tile, coordinate points in the lens-distorted image corresponding to each selected coordinate point in the output image are calculated. In addition, for each tile, a bounding box on the lens-distorted image is selected. The bounding box includes the calculated coordinates in the lens-distorted image. The bounding boxes are expanded so that they encompass all coordinate points in the lens-distorted image that map to all coordinate points in their respective corresponding tiles. Output pixel values are generated for each tile from pixel values in their corresponding expanded bounding boxes.

摘要： A system and an apparatus for improving image quality of an object (140) in video telephony are described. The apparatus comprises an image detection unit (210), an image alignment unit (220) and an image fusion unit (230). A near infrared light source (240) in the image detection unit (210) illuminates the object (140), such that the object (140) is front illuminated. An image sensor (250) alongside the near infrared light source (240) generates a near infrared image and a visible image. An image alignment unit (220) aligns the near infrared image and the visible image. An image fusion unit (230) fuses the aligned near infrared image and aligned visible image pair to form a composite image of the object (140). The composite image of the object (140) has improved image quality, image detail, and a reduction in shadows.

摘要： A process composes a content license for a set of content. The content license has a static portion and a dynamic portion. Further, the process inserts a master key into the static portion. In addition, the process inserts a plurality of content rule sets of values into the dynamic portion and composes a unique content encryption key for each segment of content associated with one of the content rule sets of values as each of the content rule sets of values is sequentially received during recording of the content. The unique content encryption key is based on the master key and at least a subset of the content rule set of values for a corresponding segment of the content. The unique content encryption key is utilized for encryption of each segment of the content to generate a plurality of encrypted content segments for storage on the storage medium.
