Abstract: A multimedia conferencing system includes a loud speaker system, one or more microphones for receiving a local audio signal and a remote audio signal, a state machine and an echo canceller that operates in conjunction with two reference signals to remove substantially all of a feedback signal component in the local audio signal that results from reinforcing and playing the local audio signal over the loud speaker system. The state machine operates to detect that only the local audio is active, and if so controls the operation of the echo canceller such that only the feedback component of the local audio signal is removed and the local audio signal is not suppressed.

Abstract: During a conference, a multipoint control unit (MCU) designates priority and non-priority endpoints. The MCU forms priority audio from the priority endpoint and sends that audio to the other endpoints at a normal level. However, the MCU forms non-priority audio from the non-priority endpoint and handles that audio based on whether the input audio from the priority endpoint is from speaking or not. If the priority endpoint's audio indicates a participant at that endpoint is speaking, then the MCU sends the non-priority audio to the other endpoints at a reduced level. Designation of which endpoint has priority can be based on which endpoint has a current duration of audio indicative of speech that is longer than other endpoints. Alternatively, the designation can be based on which endpoint is currently presenting content during the conference or based on a mix of speech audio and content presentation.

Abstract translation: 在会议期间，多点控制单元（MCU）指定优先级和非优先级端点。 MCU从优先级端点构成优先音频，并将该音频发送到正常级别的其他端点。 然而，MCU从非优先级终端形成非优先级音频，并且基于来自优先级端点的输入音频是否来自不同语言来处理该音频。 如果优先级端点的音频指示该端点的参与者正在说话，则MCU以降低的级别将非优先级音频发送到其他端点。 哪个端点具有优先权的指定可以基于哪个端点具有指示语音的当前持续时间长于其他端点。 或者，该指定可以基于在会议期间当前呈现内容的哪个端点或者基于语音音频和内容呈现的混合。

Abstract: Upon receiving a continuous presence video image, an endpoint of a videoconference may identify its self image and replace the self image with other video data, including an alternate video image from another endpoint or a background color. Embedded markers may be placed in a continuous presence video image corresponding to the endpoint. The embedded markers identify the location of the self image of the endpoint in the continuous presence video image. The embedded markers may be inserted by the endpoint or a multipoint control unit serving the endpoint.

Abstract: A distributed audio signal processing system having a plurality of linked audio signal processing units is disclosed. Each audio signal processing unit has physical channels for receiving and sending local audio signals and a high bandwidth interface for exchanging audio signals with other linked audio signal processing units. Each of the physical channels of each of the audio signal processing units are mapped to a corresponding global channel. The audio signal processing system provides a tightly integrated, distributed signal processing matrix where any input signal or physical channel on any one of the signal processing units can be exchanged with any other of the linked audio signal processing units, thereby providing maximum flexibility for selecting signals to mix and determining how to process the signals.

Abstract: A conferencing system for an enterprise is disclosed. The conferencing system allows a conferencing session conducted on a conferencing device within a premises to be controlled from a portable communication device. The system provides a generic user interface to the portable communication device for controlling the conferencing session. Commands for controlling the conferencing session are entered on the portable communication device and signaled to the conferencing device.

Abstract: Systems and methods of providing extended presence information for multi-user devices are described. Communication devices used in conference rooms represent a different nature than single user devices such as a personal computer. Conference rooms also have attributes that may be added to existing presence information and provide an enhanced experience for scheduling and dissemination of conference room capabilities. Information such as actual people in attendance may be added to the presence information maintained by a presence server to provide an overall enhancement to the meeting room whether it is physically a single conference room or a multitude of endpoints remotely connected to a conference.

Abstract: Configurable electronic devices contain identifying information in a dual-ported memory. A plurality of un-configured units are assembled into a set. Using identifying information, a provisioning server matches each particular unit to configuration settings needed to appropriately configure that device for use by a specific end user. The configuration settings and/or data may be transmitted to the devices via their embedded RFID systems and stored in their dual-ported memory (via the first memory port). The electronic devices may comprise processor-based systems and, upon system initialization, the configuration data can be read from the memory via a second port thereof and used to configure the device for use by the user. In this way, devices may be configured as a set destined for a particular end user immediately prior to shipment and/or deployment and it is not necessary to separately track customized units prior to assembling them into a set.

Abstract: A videoconference system can automatically transmit first and second images from a local site to a remote site where the first image is a high-resolution live image and the second image may be transmitted either as a high-resolution live or still frame image. Two video streams representing the first and second images are transmitted together to the remote site within a single carrier channel. The second image is transmitted as a still image whenever the second image is static to conserve bandwidth.

Abstract: An MRC system includes an MRM and an MRE that handle needs for Intra frames in an efficient way, improves the conferees experience, and reduces the load on the resources associated with that MRC videoconference by reducing the number of Intra frames and lowering the impact of Intra frames when they are needed. In some embodiments, when a requiring MRE requests an Intra frame for a video stream received from a presenting MRE, an MRM may respond by requesting the presenting MRE to send a temporary video stream toward the requiring MRE while sending in parallel a normal stream toward the rest of the MREs.
