  • Patent number: 8203594
    Abstract: Conventional video call attempts encountering a device inoperable according to a desired capability will fail if the receiving device is unable to complete the call at the desired service level (i.e. video). In addition to frustrating the communication attempts between users, another issue is that resources consumed in the attempted but failed exchange are not recoverable, since the call never completed. Accordingly, configurations herein substantially overcome such shortcomings by providing a fallback mechanism that identifies a service level operable by both the initiating device and the receiving device, and completes the call at a lower service level operable by both devices. The disclosed approach allows a call to complete at an alternate service level (i.e. voice instead of video) rather than failing the call completely, resulting in a source of lost revenue to the service provider (operator).

  • Patent number: 8203591
    Abstract: A method for assigning video signals includes receiving a plurality of video signals from a plurality of cameras located at one or more remote sites, the plurality of video signals for display on a plurality of monitors at a local site. The method also includes determining an optimal monitor for displaying a first video signal associated with a first camera based on the location and alignment of the first camera in relation to one or more of the plurality of cameras. In addition, the method includes calculating a respective difference between a number of video signals assigned to the optimal monitor and a respective number of video signals assigned to each respective monitor of the plurality of monitors. The method further includes assigning the first video signal to the optimal monitor if the respective difference is not greater than a threshold value with respect to each of the plurality of monitors.

  • Publication number: 20120050455
    Abstract: Hands-free services for Internet Protocol (IP) video calls through a peered hands-free device can begin when an IP video call invitation request that requests the client computing device participate in a P2P (peer-to-peer) IP video call is received. A generic incoming call object is generated based on the IP video call invitation request in a format that can be common for both incoming audio only cellular calls and IP video call invitation requests. The hands-free device is alerted of the incoming call based on the incoming call object. Responsive to receiving an indication from the hands-free device that a user has indicated to answer the incoming call, an IP video call accept message is transmitted and a P2P connection is established for the P2P IP video call, and the hands-free device can act as an auditory relay during the P2P IP video call.

  • Patent number: 7526078
    Abstract: A method for communicating data during an audio conference is provided. Digital data is received from a data source. The digital data is then modulated onto a carrier signal. The modulated carrier signal is subsequently combined with an audio signal of the audio conference. The combined signal is communicated to at least one remote communication device. Upon receipt by the at least one remote communication device, the combined signal is separated into the audio signal and the modulated carrier signal. The modulated carrier signal is then demodulated to extract the digital data. Both the digital data and the audio signal are output by the at least one remote communication device.

  • Publication number: 20090027484
    Abstract: A system is disclosed that addresses a problem that can occur when a calling party of a video call withdraws from the call, but does not actually hang up. For example, after the calling party begins working through an interactive voice and video response (IVVR) session, the party might put his phone down, step away, drop the phone inadvertently, or otherwise disengage from the call without hanging up. In this event, the terminal itself is still connected to the call, so the call resource is tied up serving the terminal, even though the calling party has temporarily disengaged from the call. The system of the illustrative embodiment detects the disengagement of the party from the call and, as a result, suspends the use of the call resource that has been allocated for the call until the party re-engages with the call.

  • Patent number: 7477282
    Abstract: A method for executing a video conference is provided that includes receiving one or more audio streams associated with a video conference from one or more end points and determining an active speaker associated with one of the end points. Audio information associated with the active speaker may be received at one or more media switches. One or more video streams may be suppressed except for a selected video stream associated with the active speaker, the selected video stream propagating to one or more of the media switches during the video conference. The selected video stream may be replicated such that it may be communicated to one or more of the end points associated with a selected one of the media switches.

  • Publication number: 20080316297
    Abstract: In various embodiments, a video conferencing device (e.g., an endpoint) may generate a video frame that includes video images of two or more video conferencing endpoints. The video frame may then be sent to a video conferencing device that may receive the video frame and separate the two or more video images into separate video images. In some embodiments, coordinate information sent along with the video frame (e.g., in metadata) may be used by the video conferencing endpoint to determine the locations of the video images in the video frame to facilitate separation of the video images. By transmitting and receiving video frames with multiple video images (from different video conferencing endpoints), multiple video conferencing endpoints can implement a multi-way video conference call without using an MCU.

  • Patent number: 7453488
    Abstract: A data call between at least two internetworked computers is established using a central server. Once the data call is in place, prerecorded motion video is shared between the two computers by creating a streaming video server on one user's computer for streaming the prerecorded motion video simultaneously to both users as clients of the streaming server. Either user can pause, rewind, or fast forward the streamed video as it is viewed by both users.

  • Patent number: 7349005
    Abstract: An automated system and method for producing videos using expert video production rules. The automated video production system and method of the present invention is particularly well-suited for the online publishing of lectures. The system of the present invention includes a camera system for capturing the lecture, such as an audience-tracking camera and a non-intrusive lecturer-tracking camera. Moreover, each camera may be controlled by a cinematographer. Tracking of a subject is performed using a history-based, reduced-motion tracker that sets up a camera shot based on the subject's movement history and leaves the shot fixed until the camera is switched. The system also includes a virtual director module having a probabilistic finite state machine (FSM) module that uses probabilistic rules and the expert video production rules to determine a current camera view.
