20140337860 | METHOD AND ARCHITECTURE FOR DATA CHANNEL VIRTUALIZATION IN AN EMBEDDED SYSTEM - A method for providing data channel virtualization between one or more devices and one or more applications is disclosed. In one example, a device policy manager (DPM) is initialized by creating an instance of the DPM before creating any application. Further, the DPM is configured for device management by identifying each device of the one or more devices and its associated device data channel (DDC) to be managed by the DPM. Each of the one or more devices is identified using an associated device identity (ID) and its corresponding DDC. Furthermore, one or more virtual data channels (VDCs) are created and provided to the one or more associated applications upon receiving a request from each of the one or more applications using a device identity (ID) and any application specific configuration parameters provided by the application. | 11-13-2014 |
20140300608 | SYSTEM AND METHOD FOR GENERATING HIGH DYNAMIC RANGE IMAGES - A method for generating a high dynamic range (HDR) image from images of a scene obtained at one or more exposure values is disclosed. In this embodiment, one of the obtained images is selected as a reference image. Further, mapped images are obtained by mapping pixel intensity values to corresponding irradiance values in each image. Furthermore, a pixel intensity value dependent weighting factor is determined. Moreover, a set of images is identified from the mapped images for pixels in the reference image. Also, a set of corresponding mapped pixels is established for the mapped pixels in reference image in the set of images. Further, a similarity measure is computed for the mapped pixels of reference image and corresponding mapped pixels in the set of images. Furthermore, each mapped pixel of the reference image is combined with a subset of its established corresponding mapped pixels in the set of images. | 10-09-2014 |

20140119451 | SYSTEM AND METHOD FOR EFFICIENT MULTI-BITRATE AND MULTI-SPATIAL RESOLUTION MEDIA ENCODING - A system and method for multi-bitrate and multi-spatial resolution media encoding are disclosed. In an embodiment for encoding a sequence of pictures at a given spatial resolution to an encoding format at a plurality of output bitrates, the sequence of pictures and a picture type for each of the pictures are received. Further, best combinations of encoding parameters for each coding tree block (CTB) in each of the pictures are identified from a determined set of combinations of encoding parameters supported by the encoding format for the associated picture type. Furthermore, the sequence of pictures are encoded using the best of the identified combinations of encoding parameters for each CTB in each of the pictures to create media bit streams at the plurality of output bitrates. | 05-01-2014 |
20140109111 | METHOD AND ARCHITECTURE FOR EXCEPTION AND EVENT MANAGEMENT IN AN EMBEDDED SOFTWARE SYSTEM - A method for providing a dedicated software framework for exception and event management in an embedded software system is disclosed. In one embodiment, each of exceptions/events originated from users are uniquely identified and severity of the exceptions/events is categorized.
