  • Patent number: 10484648
    Abstract: Systems and methods enabling inbound calls to controlled-environment facility resident telephone numbers employ resident-associated communications devices deployed in the facilities. An inbound and outbound calling platform assigns a telephone number to each resident and associates a routable (IP) address of each resident communications device with such telephone number. This calling platform also presents an online directory to accessing inbound callers that lists residents the caller is allowed to call, the telephone number(s) of such resident(s), and whether such residents and their communications devices are ready to receive a call. The calling platform reconfirms such information upon an inbound call being placed to a telephone number assigned to a resident and signals the resident communications device associated with the resident assigned that telephone number.

  • Patent number: 10462424
    Abstract: A videoconferencing system has a videoconferencing unit that use portable devices as peripherals for the system. The portable devices obtain near-end audio and send the audio to the videoconferencing unit via a wireless connection. In turn, the videoconferencing unit sends the near-end audio from the loudest portable device along with near-end video to the far-end. The portable devices can control the videoconferencing unit and can initially establish the videoconference by connecting with the far-end and then transferring operations to the videoconferencing unit. To deal with acoustic coupling between the unit's loudspeaker and the portable device's microphone, the unit uses an echo canceller that is compensated for differences in the clocks used in the A/D and D/A converters of the loudspeaker and microphone.

  • Patent number: 10455194
    Abstract: Techniques for handling sudden changes in available bandwidth in videoconferences implemented with media servers employing SFUs. The techniques involve detecting a sudden drop in available egress network bandwidth from a media server to a video receiver, sending a request to a video sender currently sending a video stream to the media server for forwarding to the video receiver to reduce its transmission bitrate, determining whether to reset the forwarding of the video stream to the video receiver, and, having determined to reset the forwarding of the video stream to the video receiver, stopping the forwarding of the video stream to the video receiver, sending a request for an I-frame to the video sender for use in restarting the forwarding of the video stream to the video receiver, and, having received the requested I-frame, restarting the forwarding of the video stream from the video sender to the video receiver.

  • Patent number: 10455184
    Abstract: Provided is a display device configured to display a video, and an information processing terminal device configured to control transmission of a video to the display device. When a video-reproducing device detects a jumping movement of a user, the video-reproducing device determines that an instruction is given to move a viewpoint position to a place on which a target mark is displayed, and transmits a request for stopping transmission to a video-providing device as a transmission source of a currently displayed video, and transmits a request for starting transmission to a video-providing device as a moving destination. When transmission of a video from the video-providing device as the moving destination is started, the movement in viewpoint is achieved, and a video captured from a new viewpoint position is allowed to be viewed on the video-reproducing device.

  • Patent number: 10455341
    Abstract: A noise monitoring system has at least two microphones and a microphones sensitivity register. The microphones are arranged physically with respect to each other such that when the microphones are placed within an acoustic field to be monitored, the RMS signal level of that acoustic field at each of the microphones is substantially the same for a monitoring frequency range. The microphones sensitivity register has reference data indicative of an initial sensitivity difference (?0) between output RMS signal levels measured by the microphones in a reference acoustic field. A current difference (?1, ?2) between the RMS signal levels concurrently output by the microphones for the currently monitored acoustic field is compared. A fault signal is generated if the current difference (?1, ?2) differs from the initial sensitivity difference (?0) more than an acceptable limit.

  • Patent number: 10455348
    Abstract: An audio control system can automatically determine an occupancy of an audience seating area, and can automatically adjust a spectral content of an audio signal to at least partially compensate for spectral effects caused by the occupancy in the audience seating area. Such an audio control system can ensure that the sound in a particular room remains constant, or nearly constant, from performance to performance. The occupancy can include a number of people in attendance in the audience seating area, and/or locations of attendees in the audience seating area. The audio control system can automatically adjust the spectral content a single time, at the start of a performance, or can optionally automatically dynamically update the adjustment throughout the performance based on subsequent measurements of the occupancy. The system can determine the occupancy through ticket sales, and/or analysis of imaging of the seats in the audience seating area.
