摘要： Real-time multimedia services are transmitted over a hybrid network including a nonguaranteed quality of service packet switched local area network and a circuit switched ISDN wide area network having a centralized multimedia bridge located within the wide area network. The local area networks and multimedia bridge are interconnected via ISDN routers. An algorithm executed by the multimedia bridge receives signals from the packet switched network and detects the absence of properties needed for real-time audio visual services. The data signals are processed to compensate for the absence of the properties and then are transmitted over the wide area network to enable real-time audio visual services.

摘要： In a multicast capable IP network implemented over an ATM network, each client terminal on a multimedia conference, for each media type it transmits, is assigned a multicast IP address and a port number (together known as a socket) on which to transmit packets, wherein each assigned multicast IP address is unique and different than the multicast IP address assigned to any other client for any media type. Each client terminal then selects, for each media type, which clients on the conference it wants to receive packets from. Only packets that are in fact requested by a client are routed over the multicast IP network to the requesting client. A single special purpose Multicast Address Resolution System (MARS) server is associated with the conference when the conference is established. Each client terminal uses that MARS server, whether on the same or different IP sub-networks, but on a common ATM network, for purposes of mapping the multicast IP addresses used in the conference into a set of unicast ATM endpoint addresses used by the ATM-connected client terminals. Similarly, when a specific conference uses a Multicast Server, a single special purpose Multicast Server is used for all clients on the conference, whether on the same or different IP sub-networks, for purposes of establishing point-to-multipoint ATM connections to the conference endpoints.
摘要翻译：在通过ATM网络实现的多播能力的IP网络中，对于其发送的每种媒体类型，在多媒体会议上的每个客户端被分配有在其上传送分组的多播IP地址和端口号（一起被称为套接字）其中每个分配的多播IP地址是唯一的，并且与针对任何媒体类型分配给任何其他客户端的多播IP地址不同。然后，每个客户端终端针对每种媒体类型选择要在其上接收分组的会议上哪些客户端。事实上客户端请求的报文只能通过组播IP网络路由到请求客户端。当会议建立时，单个专用组播地址解析系统（MARS）服务器与会议相关联。每个客户终端使用该MARS服务器，无论是在相同或不同的IP子网上，但是在公共ATM网络上，用于将会议中使用的组播IP地址映射到由ATM使用的一组单播ATM端点地址连接的客户终端。类似地，当特定会议使用多播服务器时，无论是在相同的还是不同的IP子网上，单个专用多播服务器被用于会议上的所有客户端，以便建立到多个组播服务器的点对多点ATM连接会议端点。

摘要： We have realized that for a connection over a large data network, such as an Internet connection that couples a web access device to a terminal server connected to an applications server, delays associated with the process of downloading large data files over such a connection, occur primarily in the leg of the connection that couples the applications server to a terminal server while little congestion is typically observed in the leg of the connection that couples the Internet access device to the terminal server. The aforementioned delay is reduced by establishing a separate connection from the applications server to the Point Of Presence server outside or independently of the backbone of the large data network thereby allowing users to receive enhanced grade of service for file transfer operations.
摘要翻译：我们已经意识到，对于通过将网络访问设备耦合到连接到应用服务器的终端服务器的大型数据网络的连接，发生与通过这样的连接下载大数据文件的过程相关的延迟主要是在将应用服务器耦合到终端服务器的连接中，通常在将因特网接入设备耦合到终端服务器的连接中通常观察到拥塞很少。通过在大数据网络的骨干网之外建立与应用服务器到存在点服务点的单独连接，可以减少上述延迟，从而允许用户接收文件传输操作的增强等级的服务。

摘要： Real time delivery of multimedia information accessed either through the Internet, or otherwise, simultaneously, or sequentially time delayed to one more users, is enabled by delivering the multimedia information over a switched network via a multipoint control unit. A client establishes a connection with a server, or other remote location where desired multimedia information is resident, identifies the desired multimedia information and provides client information identifying the locations of the users. The client information may include the telephone numbers or other access numbers of each of the multiple users. The multimedia information is then delivered by a multimedia server to a bridging apparatus through a switched network guaranteeing high quality of service, secure connection and billing control. Connecting one or more users to a live agent is also made possible by providing the telephone numbers of the users and the live agent directly to the multipoint control unit. The delivery of the multimedia information can be secured by comparing the client information to a segmented "to call" list to determine whether the client is authorized to receive the requested multimedia information. Alternatively, or in addition, security can be implemented by mounting a video camera at the client's endpoint and connecting a database running face recognition software to the multimedia server. The multimedia server's call to the user triggers the camera to take a picture of the user. The selected content is restricted to authorized users by comparing the picture to pictures of authorized faces stored in the database.

摘要： A multimedia telecommunications network provides telephone service which may involve one or more of audio, video, and data communications. In one example of the invention, the multimedia telecommunications network contains a virtual meeting services complex which provides multimedia telecommunications service to subscribers of the network. Multimedia telephone calls can be completed automatically by the virtual meeting services complex in a manner similar to that now used to complete conventional audio telephone calls. The multimedia telecommunications network containing this virtual meeting services complex is able to connect together users having diverse equipment and is able to handle integrated and nonintegrated network access mechanisms.

Each client terminal then selects, for each media type, which clients on the conference it wants to receive packets from. Only packets that are in fact requested by a client are routed over the multicast IP network to the requesting client. When a conference originator establishes the conference, a number of multicast IP addresses are allocated for later assignment to the clients during the conference. As each client joins the conference, it is assigned a multicast IP address from the allocated group for each media type it will transmit. Those assigned addresses are then marked as unavailable for assignment to any other client that subsequently joins the conference. When the original client later exits the conference, its assigned multicast IP address(es) is (are) marked as available for assignment to a later joining client. At the conclusion of the conference, all multicast IP addresses allocated to the conference are marked as available for use in another conference.

摘要： A communications system uses a World Wide Web (Web) server to provide multimedia messaging functions over the Internet. Multimedia workstations are interconnected via the public switched telephone network (PSTN). Parties are provided with multimedia mailboxes on message servers that are connected to the PSTN and the Internet. In order to identify the message server on which a called party's mailbox is located, the Web server provides the multimedia number of the called party's message server when a call is made. In addition, the Web server provides the multimedia number of the called party. When a multimedia call is unanswered, the system uses the multimedia number of the message server and the called party multimedia number provided by the Web server to record and store a message for the called party in the called party's mailbox.

摘要： A network-based device creates composite video streams containing video images of users for display on video conferencing screens. Video image streams are cascaded through a series of quad boxes to create combined video streams and ultimately the composite video stream. The composite video stream produces a display grid comprised of a plurality of image boxes. The device uses quad box input port mapping to direct a specific video image stream to a specific image box by controlling the cascade path of each video image stream through the quad boxes in creating the composite video stream. A user interface permits a user to selectively determine the layout of user images on the video conferencing screen. Screen layout extends to size of each user image being incrementally controlled and location of each user image being selectively determined depending upon the size and the number of the various user images. By controlling size and location of each user image, the screen display area available for other uses, such as the display of applications programs, is increased.
