| 20090282475 | Media Streams from Containers Processed by Hosted Code - Described is a technology by which code, such as an untrusted web application hosted in a browser, provides content through an interface for playback by an application environment, such as an application environment running in a browser plug-in. Content may be in the form of elementary video, audio and/or script streams. The content is in a container that is unpackaged by the application code, whereby the content may be packaged in any format that the application understands, and/or or come from any source from which the application can download the container. An application environment component such as a platform-level media element receives information from an application that informs the application environment that the application is to provide media stream data for playback. The application environment requests media stream data (e.g., samples) from the application, receives them as processed by the application, and provides the requested media stream data for playback. | 11-12-2009 |

| 20110307739 | MULTIMEDIA HARDWARE EMULATION FOR APPLICATION TESTING - A multimedia testing system is described herein that uses a virtual hardware driver to test software application behavior using virtual hardware in place of physical hardware devices. The virtual hardware driver receives customized input patterns that emulate behavior and formatting of data from a wide variety of hardware devices. For webcams, the system can send a steady stream of frames like those that would be provided as output from a physical webcam. A test environment can observe software interaction with the received customized input patterns to determine how the software will interact with various physical hardware devices. Thus, the multimedia testing system allows automated testing of a software application that interacts with multimedia hardware without physically buying and installing hardware devices. | 12-15-2011 |

| 20090168695 | DEFINING A BOUNDARY FOR WIRELESS NETWORK USING PHYSICAL ACCESS CONTROL SYSTEMS - A system and method for defining a boundary within a wireless coverage area using a physical access control system (PACS) and limiting access to the wireless network to devices located within the boundary area is provided. The system includes a PACS for controlling access to a secured area defined by the boundary to authorized personnel and a wireless network generating system for generating a wireless network. Access to the wireless network is limited to devices associated with an authorized personnel when the authorized personnel is determined to be within the secured area and denied to devices associated to personnel determined to be outside the secured area. | 07-02-2009 |

| 20080219356 | SYSTEM AND METHOD FOR TRANSCODING DATA FROM ONE VIDEO STANDARD TO ANOTHER VIDEO STANDARD - A system and method transcodes an input video bit stream having a first encoding profile into an output video bit stream having a second encoding profile. The system includes a first module ( | 09-11-2008 |
| 20100158108 | SYSTEM AND METHOD FOR VIDEO ENCODING - An embodiment of the present disclosure relates to system comprises an encoding device. Said encoding device comprises a compression unit, a quantizer, a bit estimator, a bit rate encoder and a variable length encoder. An embodiment also is a method of encoding. Said method estimates a number of bits to encode a macroblock after compressing the data stream. Then the estimated bit encoded by a bit rate encoder and further quantized by the quantizer to get the final encoded bit stream. The number of bits required to encode a macroblock is estimated after the quantization process and before the encoding process. The macroblock bit estimator estimates the number of bits required to encode a particular macroblock depending on the quantized AC coefficients of that macroblock and the quantized AC coefficients of the neighboring frames normalized at a macroblock level. | 06-24-2010 |

| 20090154558 | METHOD FOR ADAPTIVE BIASING OF FULLY DIFFERENTIAL GAIN BOOSTED OPERATIONAL AMPLIFIERS - Rate control algorithms are adapted to cover multiple encoding standards are described. A rate controller includes an input adaptation interface, a core rate controller, and an output adaptation interface. The input adaptation interface converts rate control input parameters of a target encoding standard to corresponding native control input parameters of the rate controller. The core rate controller is coupled to the output of the input adaptation interface generating output parameters conforming to its native encoding standard. The output adaptation interface is coupled to the output of the core rate controller converting the generated output parameters to equivalent rate control output parameters conforming to the target encoding standard. | 06-18-2009 |
| 20100067580 | NON-SCALABLE TO SCALABLE VIDEO CONVERTER - Systems and methods are for implementing a NSV2SV converter that converts a non-scalable video signal to a scalable video signal. In an implementation, a non-scalable video signal encoded in H.264/AVC standard is decoded and segmented into spatial data and motion data. The spatial data is resized into a desired resolution by down-sampling the spatial data. The motion data is also resized in every layer, except in the top layer, of a scalable video coding (SVC) encoder by using an appropriate measure. Further, the motion data is refined based on the resized spatial data in every layer of the SVC encoder. The refined motion data and the down-sampled spatial data are then transformed and entropy encoded in the SVC standard in every layer. The SVC encoded output from every layer is multiplexed to produce a scalable video signal. | 03-18-2010 |
