Abstract: A master device (e.g., a laptop) controls a videoconference connection with a far-end and acts as a controller for slave devices in a group. The master establishes the connection with the far-end using a wide area network and connects with the slaves using a Wi-Fi connection of a local area connection. To connect to the slaves, the master outputs an ultrasonic beacon encoding the master's address in the local network. The beacon also allows differences in the various clocks to be handled during audio processing. During the videoconference, the master outputs far-end audio to a loudspeaker and sends the far-end video to its display and to the slaves. Each device captures audio/video with its microphone and camera. The master determines which captured audio is a dominant talker's and may only send that audio to the far-end. The video associated with the dominant talker's device may also be sent to the far-end.

Abstract translation: 主设备（例如，笔记本电脑）控制与远端的视频会议连接，并且用作组中的从设备的控制器。 主机使用广域网建立与远端的连接，并使用局域网连接的Wi-Fi连接与从站进行连接。 要连接到从站，主站输出编码本地网络主站地址的超声波信标。 信标还允许在音频处理期间处理各种时钟的差异。 在视频会议期间，主机将远端音频输出到扬声器，并将远端视频发送到其显示器和从站。 每个设备用麦克风和相机捕获音频/视频。 主人确定哪个捕获的音频是主要的说话者，并且只能将该音频发送到远端。 与主要讲话者的设备相关的视频也可能被发送到远端。

Abstract: In videoconference camera selection, audio inputs associated with cameras for a videoconference are each processed into first and second audio energies respectively for first and second frequency ranges. The selection then determines which of the audio inputs has a greatest ratio of the first audio energy to the second audio energy and selects the associated camera view for outputting video for the videoconference. The selection can also process video inputs from the cameras either alone or in combination with the audio processing. Either way, the selection processes each of the video inputs for at least one facial characteristic and determines which of the video inputs has a greatest likelihood of framing a human face. In the end, the selection selects the associated camera view for outputting video for the videoconference based at least in part on this video-based determination.

Abstract translation: 在视频会议相机选择中，与用于视频会议的相机相关联的音频输入分别被分别用于第一和第二频率范围的第一和第二音频能量。 然后，该选择确定哪个音频输入具有第一音频能量与第二音频能量的最大比率，并且选择用于输出用于视频会议的视频的相关联的摄像机视图。 选择还可以单独处理来自摄像机的视频输入或与音频处理相结合。 无论哪种方式，选择处理至少一个面部特征的每个视频输入，并且确定哪个视频输入具有构图人脸的最大可能性。 最后，该选择至少部分地基于该基于视频的确定来选择用于输出用于视频会议的视频的相关联的摄像机视图。

Abstract: A videoconferencing system allows host users to personalize virtual meeting rooms (VMR). A multipoint control unit (MCU) generates VMRs using associated VMR configuration parameters, which include personal VMR parameters specified by the host user, and admin VMR parameters specified by an administrator of the videoconferencing system. The host user can connect to a server at the MCU to request a list of personal VMR parameters, for which the host user can specify values. The server can receive and store the specified values for the personal parameters. The MCU can combine the values of personal VMR parameters with values of admin VMR parameters in generating VMR configuration.

Abstract: A method for efficiently accessing pertinent information retrieved from a videoconferencing system call log. System call logs typically contain a chronological list of raw information pertaining to inbound and outbound videoconferencing calls. The method for efficiently accessing this chronological information is performed using input from the user at an endpoint to correlate and sort for display the information required at the current time. Videoconferencing systems typically are shared use or community type devices and the method of this disclosure allows for more user friendly access to pertinent information. Auto population of a speed dial list or associating a smart tag with the retrieved information is another possible feature to aid the end user. This method will allow a business to more efficiently use a limited number of videoconferencing systems amongst diverse groups of users with diverse calling needs.

Abstract: A videoconferencing system provides sharing program content during a videoconferencing session. A graphical user interface (GUI) allows participants to select a program to be shared and participants to share the selected program with. A scheduler communicates with the videoconferencing systems of the participants to tune or configure them to receive the selected shared program content at a scheduled time. The scheduler also communicates with a multipoint control unit (MCU) for initiating a videoconferencing session between the participants. The videoconferencing system combines mixed video streams received from the MCU with the program stream of the selected shared program and displays the combined stream on the display device. The scheduler can be located at a program service provider or at the initiating participant's videoconferencing system.

Abstract: Systems and methods of configuring an add-on device to augment the capability of existing endpoint infrastructure are disclosed. In one embodiment, a video add-on device is configured to receive, augment or downgrade, and forward messages for an existing SIP audio-only phone. The video add-on device in this embodiment can receive messages from the existing SIP audio-only phone and augment the messages with information regarding the additional video capabilities being provided. The messages can then be forwarded to an infrastructure SIP Proxy/Registrar for further routing. From the perspective of the infrastructure SIP Proxy/Registrar and other network attached devices the outbound messages from the video add-on device appear as if they originated from the video add-on device, other devices will not be directly aware of the existing SIP audio phone providing its designed function. Utilizing devices similar to the disclosed video add-on device may allow incremental corporate network endpoint upgrades.
