摘要： PROBLEM TO BE SOLVED: To provide a method for reducing the number of retransmission requests of a compress media transferring system implemented in a network where packet loss may occur.SOLUTION: An extended header for each transmitted packet can indicate a priority of the packet and a plurality of endpoints can determine if a re-transmission of a missing packet is requested. Buffering of a plurality of packets at different hops in a multi-hop system allows the retransmission request to be met by a more recent hop than the original system transmitting a video packet. Three levels of priority are established to achieve a reliable frame rate of 30 frames per second by compressing the first and second levels at 7.5 frames per second and a third level at 15 frames per second.
摘要翻译：要解决的问题：提供一种用于减少在可能发生分组丢失的网络中实现的压缩媒体传送系统的重传请求数量的方法。解决方案：每个发送的分组的扩展头部可以指示分组的优先级和多个端点可以确定是否请求丢失分组的重传。在多跳系统中的不同跳的多个分组的缓冲允许通过比发送视频分组的原始系统更近的跳跃来满足重传请求。通过以每秒7.5帧的速度压缩第一级和第二级，以每秒15帧的速度压缩第三级，建立三级优先级以实现每秒30帧的可靠帧速率。

摘要： PROBLEM TO BE SOLVED: To provide a videoconferencing system which compensates for different audio clocks between devices using an ultrasonic beacon.SOLUTION: The videoconferencing system has a videoconferencing unit which can use portable devices as peripherals for the system. The portable devices obtain near-end audio and transmit the audio to the videoconferencing unit 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 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 which compensates for differences in the clocks used in the A/D and D/A converters of the loudspeaker and microphone.
摘要翻译：要解决的问题：提供一种视频会议系统，其使用超声波信标对设备之间的不同音频时钟进行补偿。
解决方案：视频会议系统具有视频会议单元，可以将便携式设备用作系统的外围设备。便携式设备获得近端音频，并通过无线连接将音频传输到视频会议单元。然后，视频会议单元将从最大便携式设备接收的近端音频与近端视频一起发送到远端。便携式设备可以控制视频会议单元，并且可以通过与远端连接然后将操作传送到视频会议单元来最初建立视频会议。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 a system and method for adapting the layout of a screen splitting video conference in accordance with interactions between conferees.SOLUTION: Using regions of interest found in video images, the arrangement of images of conferees is dynamically arranged as displayed by endpoints. Arrangements are configured to be responsive to various metrics, including the position of conferees in a room and dominant conferees in the videoconference. Video images are manipulated as part of the arrangements, including cropping and mirroring the video images. As interactions between conferees change, the layout is automatically rearranged in response to the changed interactions.

摘要： PROBLEM TO BE SOLVED: To provide a keyboard arrangement which are more inexpensive by reducing the number of signal lines.
SOLUTION: The keyboard arrangement comprises a plurality of keys and a keyboard decoder. Each of the plurality of keys includes at least one drive contact and a plurality of sense contacts. Each drive contact can be connected to an output (drive) line of the keyboard decoder, and each sense contact can be connected to an input (sense) line of the keyboard decoder such that each key is connected to a unique combination of sense lines. Key presses can be identified by the unique combination of sense lines triggered. The combination of sense lines triggered can be used as an address to a lookup table indicating the function of the various keys. Variations of drive signal properties (e.g., frequency, phase, and waveshape) can be used to further distinguish key inputs and/or provide for a greater number of keys and/or corresponding functions.

摘要： PROBLEM TO BE SOLVED: To improve the quality of fault detection and recovery methods of connectivity between a plurality of clients from a plurality of LANs and a networking device having a bank of processing nodes (units).
SOLUTION: A bank of processing units is connected to a number of LANs via a bank of MAC controllers. An interconnect switch allows any of the processing units to access any of the MAC controllers. A housekeeping processor periodically detects faults in the connectivity of the processing units to the LANs. When a fault is detected, a redundant processing unit is assigned to be connected to the LAN. If a fault still exists, then a redundant MAC controller is assigned to the redundant processing unit. The MAC address of the previous MAC controller is reassigned to the redundant MAC controller.

摘要： PROBLEM TO BE SOLVED: To provide a method for reconstruction of video information lost as a result of transmission errors. SOLUTION: The system and method for reconstruction of video information lost as a result of transmission errors have four aspects, including: (1) changing the bit and/or packet rate; (2) inserting redundant information into the video bitstream; (3) providing automatic refresh of certain regions of the video on a periodic basis; and (4) interleaving coded macroblocks into diversity groups for transmission to spatially spread the effect of lost packets. The image reconstruction may then take advantage of these three aspects to provide an enhanced result in the presence of transmission losses. COPYRIGHT: (C)2007,JPO&INPIT

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 to change the aspect ratio to about 4:3. In one embodiment, 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 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 capable of substantially displaying the image without the stretched height. The disclosed system and method can receive signals that the endpoint has a wide screen display and can also inform a user at the endpoint to set the wide screen display to the wide or zoom modes.
