Abstract: Disclosed are systems and methods for creating indexes of recorded meetings, and particularly for creating refined indexes of recorded meeting. By way of example only, the system can record a meeting and create a starting index for the meeting based on keyword spotting. The system can also detect events that occur during the meeting that may reflect topic changes. The starting index can then be updated to reflect the topic changes to create a more useful and condensed meeting index.

Abstract: A conferencing peripheral for use with a mobile device or laptop or desktop computer can include one or more projectors, cameras, microphones, and speakers. Such a device can work with the mobile device to provide a higher quality conferencing experience than has been provided to date by projecting a substantially full size, high resolution, image of conference participants onto a screen or wall and by providing microphones, speakers, and sufficient audio processing to provide high fidelity audio as part of the conferencing experience. The peripheral may be configured to use the voice and/or data network of the mobile device or may include its own internal network interface.

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.

Abstract: A videoconference multipoint control unit (MCU) automatically generates display layouts for videoconference endpoints. Display layouts are generated based on attributes associated with video streams received from the endpoints and display configuration information of the endpoints. An endpoint can include one or more attributes in each outgoing stream. Attributes can be assigned based on video streams' role, content, camera source, etc. Display layouts can be regenerated if one or more attributes change. A mixer can generate video streams to be displayed at the endpoints based on the display layout.

Abstract: A videoconferencing system includes at least one processor and at least one camera. The endpoint can capture one or more images with the camera. The system can locate a region of interest within an image, such as the area surrounding the face of a person participating in a videoconference. If the face area or other region of interest is too dark, the system can brighten the region to make it more visible. The system can determine whether the face is too dark by comparing the captured image to previously captured images, or comparing the luma values and other data making up the face to predetermined values, or both. The system can check the modified image for over-brightening or saturation, and further adjust the image as needed. The brightening of the face area is done in such a way that the brightened region is unobtrusive to the viewer.

Abstract translation: 视频会议系统包括至少一个处理器和至少一个相机。 端点可以使用相机捕获一个或多个图像。 系统可以在图像内定位感兴趣的区域，例如参与视频会议的人的面部周围的区域。 如果脸部区域或其他感兴趣区域太暗，系统可以使该区域变亮以使其更可见。 通过将捕获的图像与先前捕获的图像进行比较，或将亮度值和构成面部的其他数据比较为预定值，或者两者，系统可以确定脸部是否太暗。 系统可以检查修改后的图像是否过亮或饱和，并根据需要进一步调整图像。 面部区域的增白以这样的方式完成，使得增亮区域对观察者不引人注意。

Abstract: Disclosed herein are methods and systems for providing continuous presence video stream in a cascading video conference, i.e., a video conference that is conducted over more than one MCU. A cascading continuous presence composition controller (CCCC) selects which endpoints from among all of the endpoints participating in the conference should be displayed in the layout, regardless of which endpoints are associated with which MCU. The CCCC can be resident on one of the MCUs, resident on a cascading conference server, or can be distributed among all of the MCUs involved in a cascading conference.

Abstract: Noise suppression systems and methods suppress far field noise in a microphone signal. A telephony system includes a main microphone and a reference microphone. In one example, the main microphone and the reference microphone can be located in the same device. In another example, the main microphone and the reference microphone can be located in two separate devices. A DSP can use the reference microphone signal to carry out suppression of far field noise in the main microphone signal. In one approach the DSP can determine an estimate of far field noise in the main microphone signal based on a noise estimate of the reference microphone signal and a reference and main microphone coupling estimate, and then subtract the far field noise estimate from the main microphone signal. Alternatively, the DSP can suppress the main microphone signal if it determines that a local talker is inactive.
