Abstract: Quick Response barcodes (“QR Codes”) are used for videoconferencing between a peripheral device and a videoconferencing system, which can include a conferencing server and/or a videoconferencing unit. Conferencing related QR codes are embedded within video frames and are identified by either a peripheral device or a videoconferencing unit. Once identified, the device or unit acts according to the information provided by the QR code. The QR codes enables the peripheral device, videoconferencing unit, and conferencing server to operation in conjunction with one another even though one or more of the device may not share a compatible operation platform that would allow for direct communication of requests and responses.

Abstract: Providing high availability multi-way conferencing. Separate signaling and media components may be provided within an MCU or among a cluster of MCUs. A signaling server may control signaling aspects of a conference while a media server may provide media support for the conference. In the event of media server failure, the signaling server may assign a new media server to provide media support for the conference. A backup signaling server may also monitor the signaling server and may provide signaling support for the conference in the event of signaling server failure.

Abstract: System and method for user interfaces using remote control devices. More specifically, these user interfaces may be particularly useful for providing an intuitive and user friendly interaction between a user and a device or application using a display, e.g., at a “10 foot” interaction level. The user interfaces may be specifically designed for interaction using a simple remote control device having a limited number of inputs. For example, the simple remote control may include directional inputs (e.g., up, down, left, right), a confirmation input (e.g., ok), and possibly a mute input. These user interfaces may allow a user to quickly browse and filter lists of items, efficiently provide input (e.g., having multiple data types), customize directional and/or mute functionality of the remote control, perform camera control (e.g., for videoconferencing), etc.

Abstract: According to one embodiment, a presence transmission method includes: controlling communication of a call via a network; transmitting, via the network, presence indicating a current status; and executing predetermined functions. If a specific function that causes delay in answering an incoming call is to be executed among the predetermined functions, presence indicating that it takes time to answer an incoming call is transmitted via the network.

Abstract: Embodiments include a telepresence system operative to carry out a teleconference, a lighting arrangement for a telepresence system operative to carry out a teleconference, and a planar panel having a reflective front surface that includes indentations having variable depth operative such that that when the reflective surface is illuminated by a light source, light is directed towards one or more participants in a telepresence system that is operative to carry out a teleconference.

Abstract: A first index corresponding to a first conversation operation and a second index corresponding to a second conversation operation are selectably displayed on a screen of a video output device. When a communicator receives a conversation request from another device, a controller determines whether the first index or the second index is selected on the screen or whether an operating member is operated. If the first index is selected, the controller performs the first conversation operation. If the second index is selected, the controller performs the second conversation operation. If the operating member is operated, the controller performs the second conversation operation.

Abstract: Systems and methods of visually indicating one or more gestures of a user of a node (22) in the content of a media stream (24) are disclosed. A node (22) configured to transmit a media stream (24) having content to one or more other nodes (22) includes a screen configured to display the content of the media stream, a media device (36) configured to capture an image of one or more gestures of the user of the node (22), wherein the one or more gestures are adjacent to the screen and the media device (36) is positioned to capture the image without capturing more than a peripheral view of the screen in that image; a media analyzer (38) configured to generate a visual representation of the captured one or more gestures; and a compositer (40) configured to composite the visual representation of the captured one or more gestures with the content of the media stream (24).

Abstract: Disclosed are a scene video switch system and a scene video switch method. The system comprises an input unit configured to input an image currently captured by a video capture unit to serve as a current image; a detection unit configured to detect all of interesting elements and latent elements in the current image so as to determine a maximum possible existing area of the interesting elements; a state switch unit configured to carry out, by using a predetermined finite state machine, switching between scene states of the maximum possible existing area according to predetermined different scene states and switching conditions; and a display unit configured to extract, based on a current scene state switched by the state switch unit, an area of concern coinciding with the current scene state from the maximum possible existing area to serve as a scene video for display.

Abstract: The present invention provides a multi-channel video communication system which includes a scalable video codec, a bit-stream truncating module, a network module and a multi-channel bit-stream truncating control module. The scalable video codec encodes a video source to generate a scalable original video bit-stream. The bit-stream truncating module is set between the scalable video codec and the network module, truncates the original video bit-stream to obtain a final video bit-stream and sends the final video bit-stream to the remote client device through the network module. The multi-channel bit-stream truncating control module is connected with the bit-stream truncating module, calculates a filter parameter for each bit-stream truncating unit in the bit-stream truncating module based on received device capabilities and network conditions of the remote client device. The present invention also provides a multi-channel video communication method in the above multi-channel video communication system.

Abstract: A method and apparatus for performing lawful intercept in a group call is described. A group call for is established and at least one target member device of the group call is identified as corresponding to a subject to be tracked. Call content for communications corresponding to the call is then tracked from the beginning of the call. A query is presented to a law enforcement authority to determine whether the law enforcement authority wishes to receive call data collected before the target joined the call or after the target leaves the call.

Abstract: A conference system provides metadata about the display of a multimedia stream to allow communication endpoints to control the format of a video conference. A multipoint control unit (MCU) can provide metadata that describes the display layout and other information about the multimedia stream. After setting up the conference, the MCU can generate a layout description in eXstensible Markup Language (XML) that can be sent to and understood by the communication endpoints. The communication endpoints can read and interpret the XML metadata to determine how the display layout is configured. If desired by the user, the communication endpoint can change the display layout or other multimedia stream function based on the received metadata.
