| 20080297532 | ROTATION AND SCALING OPTIMIZATION FOR MOBILE DEVICES - Image processing in mobile devices is optimized by combining at least two of the color conversion, rotation, and scaling operations. Received images, such as still images or frames of video stream, are subjected to a combined transformation after decoding, where each pixel is color converted (e.g. from YUV to RGB), rotated, and scaled as needed. By combining two or three of the processes into one, read/write operations consuming significant processing and memory resources are reduced enabling processing of higher resolution images and/or power and processing resource savings. | 12-04-2008 |
| 20100189179 | VIDEO ENCODING USING PREVIOUSLY CALCULATED MOTION INFORMATION - A video encoder uses previously calculated motion information for inter frame coding to achieve faster computation speed for video compression. In a multi bit rate application, motion information produced by motion estimation for inter frame coding of a compressed video bit stream at one bit rate is passed on to a subsequent encoding of the video at a lower bit rate. The video encoder chooses to use the previously calculated motion information for inter frame coding at the lower bit rate if the video resolution is unchanged. A multi core motion information pre-calculation produces motion information prior to encoding by dividing motion estimation of each inter frame to separate CPU cores. | 07-29-2010 |
| 20100189183 | MULTIPLE BIT RATE VIDEO ENCODING USING VARIABLE BIT RATE AND DYNAMIC RESOLUTION FOR ADAPTIVE VIDEO STREAMING - A video encoding system encodes video streams for multiple bit rate video streaming using an approach that permits the encoded bit rate to vary subject to a peak bit rate and average bit rate constraints for higher quality streams, while a bottom bit rate stream is encoded to achieve a constant chunk rate. The video encoding system also dynamically decides an encoding resolution for segments of the multiple bit rate video streams that varies with video complexity so as to achieve a better visual experience for multiple bit rate streaming. | 07-29-2010 |
| 20100316126 | MOTION BASED DYNAMIC RESOLUTION MULTIPLE BIT RATE VIDEO ENCODING - A video encoding system encodes video streams for multiple bit rate video streaming using an approach that permits the encoded resolution to vary based, at least in part, on motion complexity. The video encoding system dynamically decides an encoding resolution for segments of the multiple bit rate video streams that varies with video complexity so as to achieve a better visual experience for multiple bit rate streaming. Motion complexity may be considered separately, or along with spatial complexity, in making the resolution decision. | 12-16-2010 |
| 20110202509 | EFFICIENT EXTRACTION AND COMPRESSION OF DATA - A device for dynamically extracting and compressing information for a streaming media asset is provided. One embodiment of the device provides a computing device comprising a processor and memory comprising instructions stored therein that are executable by the processor. The instructions stored in the memory are executable to provide to a requesting computing device dynamically compressed information for a streaming media asset, the dynamically compressed information derived from an information file comprising variable data elements arranged in one or more data fields according to a well-known structure. For example, the instructions are executable to receive from the requesting computing device a request for the compressed information, extract the variable data elements from the information file, compress the variable data elements to form compressed data elements, and send to the requesting computing device a compressed file comprising the compressed data elements. | 08-18-2011 |

| 20110085664 | SYSTEMS AND METHODS FOR MANAGING MULTIPLE KEYS FOR FILE ENCRYPTION AND DECRYPTION - Systems and methods for managing multiple keys for file encryption and decryption may provide an encrypted list of previously used keys. The list itself may be encrypted using a current key. To decrypt files that are encrypted in one or more of the previous keys, the list can be decrypted, and the appropriate previous key can be retrieved. To re-key files, an automated process can decrypt any files using previous keys and encrypt them using the current key. If a new current key is introduced, the prior current key can be used to decrypt the list of keys, the prior current key can be added to the list, and the list can be re-encrypted using the new current key. | 04-14-2011 |
| 20110106948 | Running Internet Applications with Low Rights - In various embodiments, applications that are configured to interact with the Internet in some way are executed in a restricted process with a reduced privilege level that can prohibit the application from accessing portions of an associated computing device. For example, in some embodiments, the restricted process can prohibit applications from read and write access to portions of a system's computer-readable media, such as the hard disk, that contains administrative data and settings information and user data and settings. In these embodiments, a special portion of the disk, termed a “containment zone”, is designated and used by applications in this restricted process. | 05-05-2011 |
