摘要： PROBLEM TO BE SOLVED: To provide a videoconferencing system having a videoconferencing unit which can use portable devices as peripherals for the system.SOLUTION: Portable devices 50 obtain near-end audio and transmit the audio to a videoconferencing unit 100 via a wireless connection. Then, the videoconferencing unit transmits the near-end audio received from the loudest portable device along with near-end video to a far-end 30. 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 which compensates for differences in the clocks used in A/D and D/A converters of the loudspeaker and microphone.
摘要翻译：要解决的问题：提供具有视频会议单元的视频会议系统，其可以使用便携式设备作为系统的外围设备。
解决方案：便携式设备50获得近端音频，并通过无线连接将音频传输到视频会议单元100。然后，视频会议单元将从最大便携式设备接收的近端音频和近端视频一起发送到远端30.便携式设备可以控制视频会议单元，并且可以通过与远端视频会议单元连接来最初建立视频会议，结束然后将操作传送到视频会议单元。为了处理单元的扬声器和便携式设备的麦克风之间的声耦合，该单元使用回波消除器来补偿扬声器和麦克风的A / D和D / A转换器中使用的时钟的差异。版权所有（C）2013，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an audio codec for audio and video conferencing which compress high-fidelity audio input so that a resulting signal for transmission retains the best quality but requires the least number of bits.SOLUTION: A scalable audio codec determines first and second bit allocations for each frame of input audio. First bits are allocated for a first frequency band, and second bits are allocated for a second frequency band. The allocations are made on a frame-by-frame basis based on an energy ratio between the two bands. The codec transform-codes both frequency bands into two sets of transform coefficients, which are then packetized based on the bit allocations. Additionally, frequency regions of the transform coefficients are arranged in order of importance determined by power levels and perceptual modeling. Should bit stripping occur, a decoder at a receiving device can produce audio of suitable quality given that bits have been allocated between the bands and the regions of the transform coefficients have been ordered by importance.
摘要翻译：要解决的问题：提供用于音频和视频会议的音频编解码器，其压缩高保真音频输入，使得用于传输的结果信号保持最佳质量，但是需要最少数量的比特。解决方案：可扩展音频编解码器为每帧输入音频确定第一和第二位分配。为第一频带分配第一比特，并且为第二频带分配第二比特。基于两个频带之间的能量比，逐帧地进行分配。编解码器将两个频带转换为两组变换系数，然后根据比特分配将其分组化。此外，变换系数的频率区域按照由功率水平和感知建模确定的重要性的顺序排列。如果发生位剥离，则在接收设备处的解码器可以产生具有适当质量的音频，因为已经在频带之间分配了比特，并且已经按照重要性排列了变换系数的区域。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a videoconferencing apparatus that can dynamically adjust image capturing of participants in a video conference depending on the environment of the video conference, seating arrangement of the participants, and the person who is speaking.SOLUTION: A videoconferencing apparatus automatically tracks speakers in a room and dynamically switches between a controlled, people-view camera 50A and a fixed, room-view camera 50A. When no one is speaking, the apparatus 10 shows the room view to the far-end. When there is a dominant speaker in the room, the apparatus directs the people-view camera at the dominant speaker and switches from the room-view camera to the people-view camera. When there is a new speaker in the room, the apparatus switches to the room-view camera first, directs the people-view camera at the new speaker, and then switches to the people-view camera directed at the new speaker. When there are two near-end speakers engaged in a conversation, the apparatus tracks them and causes the people-view camera to zoom-in so that both speakers are in view.
摘要翻译：要解决的问题：提供一种视频会议装置，其可以根据视频会议的环境，参与者的座位安排和正在说话的人动态地调整视频会议中的参与者的图像捕获。解决方案：视频会议设备自动跟踪房间中的扬声器，并且在被控制的人物摄像机50A和固定的室内摄像机50A之间动态切换。当没有人在说话时，装置10显示到远端的房间视图。当房间中有主导扬声器时，设备将人物摄像机引导到主扬声器，并从室内摄像机切换到人民摄像机。当房间里有一个新的扬声器时，设备首先切换到室内摄像机，将人物摄像机引导到新的扬声器，然后切换到指向新扬声器的人物摄像机。当有两个近端扬声器进行通话时，该设备将跟踪它们并使人们观看的相机放大，以便两个扬声器都在视野中。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method to efficiently determining and displaying pertinent information determined from a plurality of inputs and calculated parameter related to a video conference. SOLUTION: The method for efficiently determining and displaying personal information is performed using an input from a user at an endpoint and information calculated during a video conference so as to present the personal information about a current speaker to all participants. A video conference system is typically used by a plurality of people at multiple locations. The method allows more users to interact and allows knowledge transfer among the participants. By sharing the information at different locations, each participant is more aware of a speaker at any given time and is more aware of importance to be applied to what the particular speaker talks.

摘要： PROBLEM TO BE SOLVED: To provide a system and a method for preparing video conference images. SOLUTION: An endpoint has a wide screen display, and the disclosed system creates an image, with an aspect ratio of about 16:9 for the endpoint. The image is altered or modified so as to vary the aspect ratio to about 4:3. In one example, two portions can be added to the image to increase the overall height of the image. The wide screen display is set to a zoom mode and is capable of substantially displaying the image without added portions. Alternatively, the image is stretched along its height by a factor of 4/3. The wide screen display is set to the wide mode and is capable of substantially displaying the image without the stretched height. The disclosed system and method can receive signals where the endpoint has a wide screen display and can also inform a user at the endpoint, to set the wide screen display to a wide or a zoom modes.
