Abstract: A system and method for a video conferencing system with meeting migration allows a client device to host a video conference meeting while connected to a video conferencing system in a first conference room. At any point during the meeting, the video conference may be paused and the current state of the video conference in a first conference room may be saved. The video conference meeting may then be migrated to a second conference room without having to restart the video conference. Client devices that have connected to the video conferencing system as well as client devices that have joined the video conference, the contents of the shared display, and other elements of the video conference are saved and restarted in the second conference room.

Abstract: A system and method for receiving video from multiple sources, compositing those sources and then republishing the composited video as a source to a virtual camera driver endpoint. In one embodiment, the present method comprises displaying multiple media streams, represented by worksurface image on a shared display. The shared display worksurface image is then re-encoded, and the re-encoded composite image is transmitted to a client computer, where the re-encoded image is transcoded to simulate a device connected to the client computer. The transcoded media stream is then transmitted to a teleconferencing system.

Abstract: Systems and methods determine occupancy of a mobile device in a room based on one or more wireless signals measured by the mobile device. The mobile device receives and processes one or more wireless signals detectable in the room to generate a feature vector that is inputted to a classifier. The wireless signals may originate either in the room or out of the room. The feature vector contains wireless-signal characteristics measured by the mobile device (e.g., time-averaged power, Fourier coefficients) that are essentially unique to a room. The classifier, which may be an artificial neural network, predicts the occupancy of the mobile device in the room from the feature vector. Alternatively, the location of the mobile device in the room may be verified, wherein the feature vector may form a training example to train the classifier.

Abstract: A bridging video conference room system and method provides for using a client device to leverage the conference room infrastructure to hold a video conference with remote users. A user may indicate an intent to host a video conference to a room-host device, which may then detect and parse a calendar invitation to cause the video conference software to launch on the user's client device as a host of the meeting. Other client devices may share content to the video conference by sharing to the bridging video conference room system without joining the video conference separately.

Abstract: Systems and methods use a mobile device to position an annotation of displayed content on a shared display coupled with a host device. Sensor data, such as gyroscope and accelerometer data, from the mobile device may be transmitted to the host device and used to generate the annotation. The sensor data may be preprocessed to smooth and fit the data to a parametric curve or shape prior to or after display on the shared display. The user of the mobile device may interact with the mobile device to further start and stop the annotation, as well as denote to animate the annotation.

Abstract: A two-tier display infrastructure switching architecture and associated method interconnects a plurality of network-enabled display devices. A video streaming switch is capable of receiving a video stream from a first network-enabled display device and forwarding the video stream to a second network-enabled display device. An access control service is capable of controlling access rights of each of the first and second network-enabled display devices to transfer video streams stream through the video streaming switch.

Abstract: A method for providing control and visualization of media. A first media stream having an initial resolution is received from a source computer; the first media stream is rescaled to generate a second media stream with a second resolution; the second media source stream is transmitted to a destination computer; after receiving instructions from the destination computer indicating a selection of the second media stream, the stream is rescaled in accordance with the received rescaling information, to generate a third media stream with a third resolution, which is transmitted to the destination computer.

Abstract: A method for graphically indicating presence, identity, and action with respect to a media post transmitted by a client device and displayed on a shared display. Metadata indicating the identity of a user is logically associated with visual media to form a media stream, which is transmitted to the shared display. The transmitted media stream is then decoded to recover the transmitted metadata. The media post is displayed on the shared display and the presence of a client device media stream, the identity of the current user of the device generating the stream, and an action associated with the user interaction with the client device, is then graphically indicated on the display, using the recovered metadata.

Abstract: A method for creating a list of display devices that are available to receive a video signal from an image generator via network video streaming. One version of the method includes transmitting a display availability packet indicating one or more of the display devices that are available for connection, updating a network display listing module with the information stored in the display availability packet, and transmitting an availability request packet requesting a list of the display devices that are available to receive the video signal. In response to receiving an availability request packet, a display resource list, indicating the display devices available to receive the video signal, is generated from the metadata contained in the availability request packet.

Abstract: A media file exchange system that supports group collaboration sessions in which media files are being shared with one or more participants. The system augments real-time media collaboration where one or more users have shared media to a group collaboration session. The system allows participants in the collaboration group to indicate their desire to share a media file to one, a few, or an entire group. The media file to be shared and a specific one of the receiving user devices are selected on a participants device other than the device owning the media. The system automatically moderates the exchange of the information between the participants.

Abstract: A system for automatic color matching of multiple displays in a multi-display system. A sensor observes the output energy of each of the displays in a multi-display system and measures the difference in the color responses for a given input color. This difference is used to derive a modification function that is applied to each display. The displays are modified accordingly, and then the color is displayed again. This process is repeated until the measured values from each of the displays are within a minimum measurement error tolerance, so that the differences in displayed colors observed among the displays are minimized.

Abstract: A system and method for measuring and then correcting the color response from multiple projectors or display devices so that the devices can generate a color response that is uniform. An area light sensor (such as a commodity camera) is used to measure the color responses of each display and then to derive a model of the color transfer function for each display using a pattern of predetermined areas or regions displayed on each display device.

Abstract: A system and method for simultaneously displaying, on a wirelessly enabled display connected to two or more of the source computers to display at least one media source from each of at least two source computers. A media source is selected, via each of the source computers. The media source is less than the entire image on the source client computer, and may constitute client data file, an application, or a video stream. Each of the selected media sources is transmitted to the display as a respective live media stream and each of the transmitted media streams is simultaneously rendered on the display.

Abstract: A method is disclosed herein that derives a post-alignment transform that is applied to the input source after the application of an alignment transform to ensure that when each source illuminates the screen, the display is aligned and retains the correct displayed aspect ratio. The transform takes into account the alignment transform and the input source aspect, and then performs a secondary, post-processing transformation that corrects the distortion induced by the alignment transform. This aspect-preserving function is a linear transform that maps pixels in the aligned space to the aligned and aspect-correct space and can be applied to the input signal after the first alignment transform, or, in the case where the alignment transform is also linear, transforms can be directly combined to derive a compound multi-projector, aspect preserving transform. In this way, the input signal to the projectors will be aligned as well as retain proper aspect.
