20140120865 | SYSTEMS AND METHODS FOR IMPLEMENTING CUSTOMIZED ROUTING IN A MODULARIZED PROCESSING ENVIRONMENT - A facility for customizable routing in a modularized routing environment is provided, where the complexities of routing functionality are not exposed to an application program. An identifier associated with a routing policy of an application program is used to configure a route table and to obtain routing instructions from the route table that are associated with the identifier. Routing is performed according to a message routing protocol, such as the Diameter protocol, for example. An interface between the facility and the application program may be implemented with an API that provides a relatively simple interface. | 05-01-2014 |
20110002381 | BITRATE CONTROL ALGORITHM FOR VIDEO TRANSCODING SYSTEMS - A video transcoding system and method employing an improved rate control algorithm. A plurality of frames in an input video bitstream are received by the system, in which each frame is in a first coding format. Each frame in the input bitstream is decoded, and complexity information indicating the complexity of the frame after decoding is obtained. An estimated number of bits to allocate for the respective frame is calculated. Using a rate estimation model that employs the complexity information for the respective frame, a picture cost for the frame is calculated based on the estimated number of bits allocated to encode the frame, and a parameter of the rate estimation model. A target cost for the respective frame is calculated based at least in part on the picture cost 10 and the complexity information for the frame. A quantization parameter (QP) is calculated that, when used to encode the respective frame in a second coding format, would generate an encoded frame having an actual cost approximately equal to the target cost. The respective frame is encoded using the calculated QP, and the frames encoded in the second coding format are provided in an output video bitstream. | 01-06-2011 |
20110002005 | MOBILE DOCUMENT IMAGING AND TRANSMISSION - A wireless communication device can send and receive realtime facsimile transmissions over a data channel available to the device. The device can implement a real time facsimile protocol over the data channel, which can generally be a packet switched network connection, such as an IP connection. An image capture device can be employed to obtain an image of a document that can be facsimile transmitted from the wireless device over the data channel. The document image may be converted to a format generally usable with facsimile transmissions. The wireless device can be configured to transmit immediately following image capture, or after a desired number of images are captured. A contact list that may be included with the wireless device may be used to select a destination address for facsimile transmission. A printing device can be the destination address to permit wireless or mobile printing. | 01-06-2011 |
20100259559 | SYSTEM AND METHOD FOR IMPLEMENTING A DYNAMIC MEDIA LINK - The disclosed system and method provide a facility for a dynamic media overlay. An end user can provide data for the dynamic media overlay that is activated upon selection to permit end users to share information while receiving or sending video data. The overlay may be in the form of a link, such as a hyperlink, that can be selected by an end user to take action indicated by information provided in the link. The link may be represented by audio or image information in the form of instructions or clickable “targets.” A content of information represented by the link can be dynamic, so that selection of the link can result in different actions, depending upon the informational content of the link. One or more flags may be provided to indicate that a new link or new informational content for a link is requested. The link may be provided in an overlay represented as a media layer provided in addition to the video media, or it may be embedded in the video media itself. | 10-14-2010 |
20100195289 | MODULAR FRONT-PANEL CONNECTIVITY ON STANDARD ARCHITECTURE SERVER APPLIANCES - A system and method for constructing a housing, such as a rack-mountable housing, for computer and telecommunications equipment, and for arranging modules, circuit boards, and other components within such a housing, to enable integration of telecommunications and information technology (IT) application services for delivering next generation, converged, network and multimedia services. The system and method provides a rack-mount server system with one or more line interface modules accessible from the front panel of the system housing, and a motherboard and a backplane with a switch fabric for allowing interconnection of the motherboard with any of the line interface modules. The rack-mount server system provides access to the high level of computing power, advanced storage technology, and standard operating systems of rack-mount server platforms, while retaining the modularity and front-panel connectivity of conventional rack-mountable telecommunications equipment. | 08-05-2010 |
20100153611 | SYSTEM AND METHOD FOR HIGH PERFORMANCE SYNCHRONOUS DRAM MEMORY CONTROLLER - The disclosed system and method enhances performance of pipelined data transactions involving FIFO buffers by implementing a transaction length indicator in a transaction header. The length indicator in the header is formed by components coupled to a memory controller through FIFO buffers. The memory controller uses the length indicator to execute pipelined data transfers at relatively high speeds without causing additional inadvertent shifts or indexes in the FIFO buffer being read. The system and method can be applied to any memory type in general, and avoids the use of additional control signals or added complexity or size in the memory controller. | 06-17-2010 |
20100112826 | INTERCONNECT DEVICE WITH DISCRETE IN-LINE COMPONENTS - An interconnect device is provided with a body through which a plurality of wells has been defined. At least one component having two terminals is provided in one or more of the wells. The component is sealed in its respective well such that the two terminals are accessible on opposite sides of the body. The body corresponds to a Ball Grid Array (BGA) device and is positioned between a BGA device and a printed circuit board (PCB). The component in the well is then inline with a solder ball on the BGA device and a corresponding pad on the PCB. Providing the component in the well frees up surface area on the PCB and also allows for positioning the component closer to a source of a signal. A component in the well is a discrete component having two terminals that may be solderable or made from a conductive pliable material. The terminals may be spring-mounted on the component. | 05-06-2010 |
20090282349 | SYSTEM AND METHOD FOR DYNAMIC CONFIGURATION OF COMPONENTS OF WEB INTERFACES - An object is implemented to represent a visual element in a user interface while being linked to data associated with the visual element. A user can manipulate the visual element through the user interface to modify the object or how the object is processed. The data associated with the visual element tracks with the modifications to the visual element and/or object to permit the data to conceptually move with the visual element. The object may be implemented using a document object model in a web browser. The object may be assigned to a user interface component that may treat the object differently in dependence upon the user manipulations. The visual element may be formed using HTML and the user manipulations may be implemented using a script. | 11-12-2009 |

20090204906 | SYSTEM AND METHOD FOR PERFORMING VIDEO COLLABORATION - Provided are systems and methods of video collaboration. End-users may participate in collaboration sessions in which inter-personal barriers are rapidly dissolved through the completing of collaborative tasks. The end-users may be grouped into teams to perform these collaborative tasks, and may be scored and/or ranked based not only on performance of the task but on the interactions between team members.

According to various examples, system architectures are described for facilitating video collaboration. In one example, the architecture includes a multi-gateway architecture that segregates functions associated with presentation of an integrated video display from functions associated with transmission of display streams to devices associated with end-users. | 08-13-2009 |
