    • A system and method for broadcasting a presentation over a computer network to an online audience. The system comprises an integrated environment that leverages many of the features of Microsoft Corporation's NETSHOW™ server technology, along with Microsoft Corporation's POWERPOINT 2000™ presentation design application program to enable a presenter to broadcast a presentation to an online audience over a computer network, such as an intranet or the Internet. The system enables a live presentation comprising a plurality of presentation slides, and audio and optionally, a visual content to be broadcast to a plurality of receiving computers over a network so that the presentation slides are displayed and the audio and visual content are replicated on the receiving computers synchronized with the presentation slides, just as in the live presentation. Preferably, the plurality of presentation slides are sent as HTML files via the computer network in advance of the start of the presentation. During the presentation, the live audio and visual content is captured and encoded into an advanced server file stream format that is streamed from a local computer (at the presenter's location) or a NETSHOW™ server to the receiving computers. The live audio and visual content is then replicated on the receiving computers using a media player. Also, slide display commands produced in conjunction with a display of the presentation slides during the presentation are streamed to the plurality of computers, so that the presentation slides are displayed on the receiving computers in synchrony with the live presentation, by loading the HTML files into a browser application program running on each of the receiving computers, in response to the slide display commands.
    • 一种用于通过计算机网络向在线观众广播演示的系统和方法。 该系统包括利用Microsoft Corporation的NETSHOW(TM)服务器技术的许多功能以及Microsoft Corporation的POWERPOINT 2000(TM)演示设计应用程序的集成环境,使演示者能够通过计算机向在线观众播放演示文稿 网络,如内联网或互联网。 该系统使得能够通过网络将包括多个演示幻灯片,音频和可选地,可视内容的实时演示广播到多个接收计算机,使得显示幻灯片被显示,并且音频和视觉内容被复制在 接收与演示幻灯片同步的计算机,就像现场演示一样。 优选地,在展示开始之前,多个演示幻灯片经由计算机网络作为HTML文件发送。 在演示期间,实时音频和视频内容被捕获并编码成从本地计算机(在演示者的位置)或NETSHOW TM服务器流式传输到接收计算机的高级服务器文件流格式。 然后使用媒体播放器在接收的计算机上复制实时音频和视频内容。 此外,在呈现期间结合演示幻灯片的显示而产生的幻灯片显示命令被流传输到多个计算机,使得演示幻灯片与实时表现同步地显示在接收计算机上,通过将HTML文件加载到 响应于幻灯片显示命令,在每个接收计算机上运行的浏览器应用程序。

    • An integrated environment for scheduling a presentation broadcast that allows a user to seamlessly schedule, make changes, replace, and reschedule a presentation broadcast from within a presentation design application program. The system leverages many of the features of Microsoft's OUTLOOK™ program to schedule a network presentation broadcast of a presentation broadcast from within the presentation design application program that is used to create or open the presentation. The user enters information concerning the presentation broadcast while within the presentation design application program, which is then automatically inserted into a meeting request message automatically sent to a list of prospective attendees of the presentation broadcast that the user has identified. The meeting request message also contains user-entered scheduling information, which is employed to automatically schedule a presentation broadcast meeting in the electronic calendars of those message recipients who choose to attend the presentation broadcast. The system also automatically schedules the presentation broadcast in the user's electronic calendar, which provides a reminder to the user to start the presentation broadcast a predefined interval before the scheduled time. Additionally, the automated scheduling is implemented for a presentation broadcast that is to originate from an Internet web server.
    • 一种用于调度演示广播的集成环境,其允许用户从呈现设计应用程序内无缝地安排,更改,替换和重新安排演示广播。 该系统利用Microsoft的OUTLOOK(TM)程序的许多功能来调度用于创建或打开演示文稿的演示设计应用程序内的演示广播的网络演示广播。 用户在呈现设计应用程序内输入关于演示文稿广播的信息,然后自动地将其插入会议请求消息中,会议请求消息被自动发送给用户已经识别的演示广播的预期参加者的列表。 会议请求消息还包括用户输入的调度信息,其用于在选择参加演示广播的那些消息接收者的电子日历中自动安排演示广播会议。 该系统还自动地安排用户的电子日程表中的演示广播,其提醒用户在预定的时间之前以预定的时间间隔开始演示。 另外,为从源自因特网网络服务器的演示广播实现自动调度。
