摘要： An enduser at a POTS analog voice-only endpoint (136) and endusers at H.320 standard multimedia terminals (101, 102, 103, 104), which each communicate over separate voice, video and data streams, engage in a videoconference with each other in a pseudo multimedia manner through a central platform (135) that provides call conversion capabilities. A document to be shared by a user at the POTS endpoint with users at the multimedia endpoints is transmitted as a data signal from a facsimile machine (137) or PC terminal (138) associated with the POTS user to a server (146) in the platform. The received data signal is then inputted to a multimedia bridge (124) and transmitted on the data stream to each multimedia endpoint for display on a window on each multimedia terminal. Similarly, a document to be shared by a multimedia endpoint is transmitted on a data stream to the multimedia bridge, where it is bridged on the data stream transmitted to the other multimedia endpoints and to the server. The document is then transmitted from the server to the facsimile machine or PC terminal associated with the POTS endpoint. In conventional multimedia conferencing arrangements, voice-activated switching is used to determine which user's video image is bridged onto the video stream transmitted to each multimedia terminal. When the audio signal from the POTS user would cause a video signal from that user's terminal to be bridged to all the multimedia endpoints if in fact that user was at a multimedia terminal, a stored image of that user is retrieved from a database (151) and outputted by the bridge on the video stream transmitted to each multimedia terminal to enable the multimedia participants to visually identify the presently talking enduser.
摘要翻译： POTS模拟语音终端（136）的终端用户和H.320标准多媒体终端（101,102,103,104）中的终端用户，每个终端用户通过单独的语音，视频和数据流进行通信，与每个终端其他以伪多媒体方式通过提供呼叫转换能力的中央平台（135）。在POTS端点处用户在多媒体端点处与用户共享的文档作为来自与POTS用户相关联的传真机（137）或PC终端（138）的数据信号发送到服务器（146）平台。然后将所接收的数据信号输入到多媒体网桥（124），并将数据流发送到每个多媒体终端，以在每个多媒体终端的窗口上显示。类似地，要由多媒体端点共享的文档在数据流上被传送到多媒体网桥，其中桥接在传输到其他多媒体端点的数据流和服务器上。然后，该文件从服务器发送到与POTS端点相关联的传真机或PC终端。在传统的多媒体会议装置中，使用语音激活的切换来确定哪个用户的视频图像被桥接到传输到每个多媒体终端的视频流上。当来自POTS用户的音频信号将导致来自该用户终端的视频信号被桥接到所有的多媒体端点，如果实际上该用户在多媒体终端，则从数据库（151）检索该用户的存储图像，并由桥上输出的视频流传输到每个多媒体终端，以使多媒体参与者可视地识别当前正在讨论的最终用户。
