     BACKGROUND OF THE INVENTION  
      When presenting in front of a group of people it is often convenient to show demonstrations and to have visual aids to help in the conveying of information. Currently presentations often involve the use of electronic slides. Products such as Microsoft PowerPoint have become valuable tools in providing electronic visual aids to presenters.  
      Products such as PowerPoint enable an individual giving a presentation to progress through a series of electronic slides that aid the viewer in following the content of the presentation. The slides may contain key points to which the presenter or narrator is focusing or they may contain diagrams or images to which the presenter may refer.  
      In giving a presentation, the presenter may wish to show a multimedia or video stream to the audience. This usually involves showing a movie or playing an audio track accompanying the presenter&#39;s narrative.  
      With current enterprises today spread over large geographic areas, it becomes difficult to gather employees in a single location. In such a case, when potential audience members are not within geographic proximity, presentations to fellow employees or group members may be difficult. In order to overcome this limitation software has been developed to allow presentations to be conducted over the Internet or over corporate networks. Software such as Lotus Sametime allows an individual to give a presentation to a remote audience. The audience may view the presentation using a web browser and is no longer required to be present at a single location. Such remote presentations may include slides or multimedia as well as a video stream of the presenter giving the talk.  
      It is often the case in presentations, both online and in person, that audience members have questions regarding the content of the presentation. Frequently the questions refer to a specific slide or a specific moment in the multimedia stream. In those cases the audience member may either interrupt the presentation to ask the question or he must wait until the speaker has completed his talk. If the speaker postpones all questions until the end of the talk, or if the presentation is being conducted remotely where the audience cannot interrupt by raising a hand or shouting, the context of the question may be lost. Any questions asked at the end based on the context of a particular slide or moment will require the presenter to rewind through the presentation in order to return to the context in which the question was asked. This is often a cumbersome, time-consuming process that must be repeated for every question asked.  
      What is lacking is a mechanism that alleviates the need for a presenter to return the context of the presentation at a particular time. By doing so questions asked regarding a particular time during the presentation may be answered without the need for cumbersome backtracking and searching.

     DETAILED DESCRIPTION OF THE PREFFERED EMBODIMENTS  
      Embodiments of the present invention are now described in detail with reference to the drawings in the figures. As described in more detail, the present invention, in some embodiments, provides a system and method for associating questions asked during an electronic presentation to a particular context. In addition, in some embodiments, the present invention describes a system and method facilitating associating questions or comments to a context of the presentation to which the question or comment relates. In addition, in some embodiments, the present invention describes a system and method for retrieving a particular portion of first content, the first content being sequentially presented while a second content may be entered.  
       FIG. 1  illustrates one embodiment of a screen that may be displayed to viewers of an online presentation. In this embodiment the presentation is viewed within a web browser  100 . A viewer of the presentation may view the speaker, presenter or moderator in a video window  102 . Slides or a multimedia stream that the moderator is showing may be viewed in another multimedia window  104 . In addition the presentation window  100  may contain a window or screen section  106  to enter text for questions or comments.  
       FIG. 2  shows one embodiment of a system to facilitate an online presentation. A moderator gives the presentation from a networked device  200 . A device may be a computer, a handheld device or any device connected to a computer network. Additionally a computer may refer to any computerized device, including handhelds, desktops, and laptops. Additionally networked devices may be connected to the network using any network protocol including both wired and wireless. The networked device from which the moderator is giving the presentation pushes content to a server  202  through a computer network such as the Internet or an enterprise intranet. The server  202  distributes the content to client devices  204 , which are connected to a computer network, which is communicatively coupled to the server computer  202 . The server  202  pushes content to the clients  204 . In order to facilitate functions according to an embodiment of the invention, the server executes a presentation program  203 . The presentation program  203  may broadly contain or include, among other things, software, modules, components, programming tools, and libraries. In addition, the presentation program  203  may be split among multiple devices or computers, and may execute as sub-programs or objects within multiple operating environments.  
      In other embodiments, the server may pull content from the moderator device  200  and the client devices  204  may pull content from the server. In some embodiments, the moderator device  200  may also act as a client device  204 .  
       FIG. 3  shows a more detailed description of how, in one embodiment, the online presentation is distributed through a computer network. A moderator uses a moderator device  200  such as a computer, which is connected to a computer network. One module executed by the moderator computer  200  is a presentation component  300 . In presenting an online presentation the moderator computer may have a video camera  301  to transmit audio or video of the moderator giving the presentation. In some cases, moderators may wish to show electronic slides during the presentation. During the presentation the moderator may wish to switch slides as the presentation progresses. In this embodiment, when the moderator changes slides on his local presentation software the presentation component  300  is notified. The presentation component  300  sends a message to the server  202  indicating that the slide has changed and containing an image of the next slide to be viewed. The server receives that message at a network interface  302  and passes it to a presentation server component  304 , executing on the server  202 .  
      The presentation server component  304  receives the image of the next slide and generates an identifier, such as a uniform resource indicator (URI) for the image. The presentation server component  304  sends a message to a World Wide Web server  306  running on the server  202 . The image of the new slide and the URI for the image are given to the web server  306 . The presentation server component  304  sends a message to all clients  204 , which are viewing the presentation. The client devices are executing a presentation component  300 . The message from presentation server component  304  to the presentation component  300  on the clients  204  contains the URI for the image of the next slide. Upon receipt of the message containing the URI of the next slide image the presentation component  300  causes the browser within which the presentation is being viewed to download the image from the web server  306 , based on the received URI.  
      During the presentation the viewer at a client computer  204  may wish to type a question or comment for the moderator. In one embodiment the viewer may type the question or comment in a text box in a browser window  106 . When the viewer begins typing the question the presentation component  300  on the client computer  204  records the URI of the current slide image being viewed. When the viewer finishes typing the question or comment the question is sent to the presentation server component  304  along with the URI for the image being shown when the questioner began typing. The presentation server component saves the text of the question or comment along with the sent URI. When the moderator retrieves the list of questions from the presentation server component  304  both the question and the image associated with the URI are returned. By doing so the moderator will have available the context in which the question was asked.  
      In some embodiments presentations use multimedia streams rather than slides during the presentations. In these cases different mechanisms may be used to indicate the context of a question. Rather than sending a URI along with the text of a question or comment, an index or time-stamp may be sent indicating a point in time during the multimedia stream when the question was typed.  
      In some embodiments, the moderator presentation component  300 , the server presentation component  302  and the viewer presentation component  300  may be executed on the same device or computer. Such an embodiment, may in some instances, be used when viewing a multimedia stream on a machine. If the viewer, for example, wishes to annotate the stream, the system may be used to record the context of the annotations. In such an embodiment, the moderator presentation component could stream the multimedia to a server running on the same computer, which transmits the multimedia to a viewer component running on the same computer, as well. Annotations typed and entered using the viewer presentation component would record the context of the annotations and facilitate retrieving the context after the completion of the multimedia stream.  
      In some embodiments, the present invention describes a system and method for retrieving a particular portion of first content, the first content being sequentially presented while a second content may be entered. An identifier may be used to identify a portion of the first content that is temporally related to the entry of the second content item. The identifier can be stored so as to facilitate retrieving the first content. The stored identifier may be used in retrieving the first content while reviewing the second content.  
       FIG. 4  shows one method of storing context information for questions and comments during an online presentation. If there are more slides to present, step  400 , the moderator changes to the next slide, step  401 . An image of the slide is sent to the server, step  402 . The server pushes an image of the slide to the viewer devices, along with an associated identifier, step  403 . The viewer devices store display the image of the next slide and record the identifier for the image, step  404 . The viewer may have a question or comment regarding the now displaying slide, decision  405 . If the viewer does have a question or comment the viewer device records the identifier for the currently displayed slide image that is being displayed when the viewer begins typing the question, step  406 . The questions or comments are sent to the server with the associated identifier, step  407 . The method then returns to decision  400 . It is possible for the method to return to decision  400  before step  407  is completed. That is, the slide may change before questions or comments are submitted regarding previous slides. If the moderator no longer has additional slides to view there may be questions or comments that the moderator will address. If there are questions are comments to address, decision  408 , questions or comments are retrieved to the moderator device along with the associated identifier, step  408 .  
      When the moderator selects a question or comment to address the image associated with the identifier is pushed to the viewer devices, thereby loading the context associated with the question or comment. If there is another question or comment the steps repeat, otherwise the presentation ends  411 .  
      While the invention has been described and illustrated in connection with preferred embodiments, many variations and modifications as will be evident to those skilled in this art may be made without departing from the spirit and scope of the invention, and the invention is thus not to be limited to the precise details of methodology or construction set forth above as such variations and modification are intended to be included within the scope of the invention.
