  1. 1. CHAPTER 2 Using IP/TV Content Manager Chapter 2 This chapter describes how to use IP/TV Content Manager. Topics covered include: • Accessing the IP/TV Content Manager • Managing IP/TV on-demand programs • Managing IP/TV scheduled programs • Recording IP/TV scheduled programs • Using the Question Manager Accessing the IP/TV Content Manager A computer used to access IP/TV Content Manager Version 3.0 must run Netscape Navigator 4.05 or 4.5x, or Microsoft Internet Explorer 4.x or 5.0. The browser must have Java and JavaScript enabled. Check the browser’s Options or Preferences menu to be sure that these features are enabled. These instructions assume that you are familiar with the Web, and have used a browser to access information sources on the Web. You should be familiar with the functions of your browser, and with concepts such as links. If not, we recommend that you read the documentation that was shipped with your browser, or explore the browser’s help system. To access the IP/TV Content Manager, go to the following URL: http://<contentmanagerhost>/ where contentmanagerhost is the DNS name or IP address of the IP/TV Content Manager.

  2. 2. Accessing the IP/TV Content Manager When you access the IP/TV Content Manager for the first time, store the URL in your Web browser’s frequently visited sites list. The actual mechanism you use varies depending on which browser you use. Refer to your browser documentation or help system for more information. When you access the IP/TV Content Manager, the first page that appears is the IP/TV Content Manager main page (see Figure 2-1). Figure 2-1 IP/TV Content Manager Main Page The IP/TV Content Manager main page contains the following links: • The OnDemand Programs link takes you to the OnDemand Programs page, which displays information about existing on-demand programs and allows you to define new on-demand categories or programs. You can also search for an on-demand category or program by program name, category, keywords, or description. See the “Managing OnDemand Programs” section later in this chapter for information. 2-2 IP/TV Content Manager User Guide
  3. 3. Accessing the IP/TV Content Manager • The Scheduled Programs link takes you to the Scheduled Programs page, which displays information about existing scheduled programs and allows you to define new scheduled programs. See the “Managing Scheduled Programs” section later in this chapter for information. • The Proximity Groups link takes you to the Proximity Groups page, which displays information about existing proximity groups, and allows you to define new proximity groups and subnets. Refer to the IP/TV Administration and Configuration Guide for information. • The Recordings link takes you to the Recordings page, which displays information about existing recordings, and allows you to define new recordings. See the “Recording Scheduled Programs” section later in this chapter for information. • The File Transfers link takes you to the File Transfers page, which displays information about existing scheduled file transfers, and allows you to define new file transfers, display the results of a file transfer, and view or clear the file transfer log. Refer to the IP/TV Administration and Configuration Guide for information. • The Server Clusters link takes you to the Server Clusters page, which displays a list of server clusters and allows you to define a new cluster or server. Refer to the IP/TV Administration and Configuration Guide for information. • The Preferences link takes you to the Preferences page, where you can set IP/TV Content Manager options. In general, preferences should only be changed by the system administrator or network manager who installed the IP/TV Content Manager. Refer to the IP/TV Administration and Configuration Guide for information. • The ServerWatch link takes you to the ServerWatch page, where you can monitor the current status of servers. On the ServerWatch page you can also go to the ServerWatch Applet window, where information about servers is dynamically updated.

  4. 4. Managing OnDemand Programs Managing OnDemand Programs This section contains procedures for defining and managing IP/TV on-demand categories and programs. Once defined, the categories and programs are listed on the IP/TV Content Manager OnDemand Programs page. Clicking either the link for an individual category or its Programs link takes you to a list of all programs in the category. The IP/TV Content Manager lets you define a hierarchy, or tree, of on-demand content in a way similar to Windows NT Explorer (see Figure 2-2). A top-level category can contain subcategories, which you go to by clicking links. This hierarchical structure facilitates the management and availability of a large library of programs. Figure 2-2 Sample Hierarchy of Content Creating a New OnDemand Category Follow these steps to create a new on-demand category: Step 1 On the IP/TV Content Manager main page, click the OnDemand Programs link. The OnDemand Programs page appears (see Figure 2-3). 2-4 IP/TV Content Manager User Guide

  7. 7. Creating a New OnDemand Category Step 3 Enter the name of the new category. Use a fairly short name, such as Instructional Videos or Employee Training. Note IP/TV Content Manager permits a name up to 60 characters long. However, when the name of the program is displayed in IP/TV Viewer or on other IP/TV Content Manager pages, the name may be truncated to fit within the display area. For this reason, it is good practice to use short program names. Step 4 Enter a description of the category. The description field allows you to enter a longer description of the category than the category name field permits. The maximum number of characters permitted in the description field is 512. Step 5 Enter keywords that can be used as search criteria by IP/TV Viewer users. Use words that are indicative of program content. Step 6 In the Contact section of the New Category page, indicate who users can contact if they have questions about the program. This information includes the program administrator’s name, telephone number, and e-mail address, as well as the name of the media producer. 12 Timesaver If you enter contact information in the root category (the 9 3 category called OnDemand Programs), this information is 6 automatically filled in for all new categories you create. Step 7 Click Add Category to send the form to the IP/TV Content Manager. If the IP/TV Content Manager finds errors or omissions in the form, the Data Entry Errors page prompts you to return to the New Category page to modify the information. When you have finished correcting the errors, click Add Category again to submit the corrections to the IP/TV Content Manager. If the form is properly completed, you return automatically to the OnDemand Programs page. Using IP/TV Content Manager 2-7

  11. 11. Creating a New OnDemand Program Note IP/TV Content Manager permits a name up to 60 characters long. However, when the name of the program is displayed in IP/TV Viewer or in other IP/TV Content Manager pages, the name may be truncated to fit within the display area. For this reason, it is good practice to use short program names. Step 4 Enter a description of the program. The Description field allows you to enter a longer description of the program than the Program Name field permits. The maximum number of characters permitted in the Description field is 512. Step 5 Enter keywords that can be used as search criteria by IP/TV Viewer users. Use words that are indicative of program content. Step 6 Enter the URL of a Web site that provides additional information about the program. If you enter a URL, a user watching this program on IP/TV Viewer can click URL and go to the Web site. Step 7 Enter a copyright statement. Step 8 Set a password for the program by entering the password in both password fields. Only users who know the password are able to view the program. Note The password protects the audio, video, and SlideCast streams in the program. If the program includes a Web Presentation stream, the Web Presentation stream is not protected. Step 9 In the Multimedia Information section of the New OnDemand Program page (see Figure 2-7), review or enter information about the source of the program. briefly describes these options.

Play SlideCast Defines whether the program includes a SlideCast portion in addition to audio or video. Play Web Presentation Defines whether the program includes a Web Presentation (for example, an ASF file containing URLs) in addition to audio or video. Transfer HTML to If selected, specifies that HTML pages and embedded graphics files of the Web Presentation Browser Cache1 are pushed to the client’s browser when the on-demand program begins. If cleared, each page is fetched dynamically by the browser. There is no impact on network bandwidth usage for either setting; the transfer simply occurs at a different time. Media length The playing time of the file. This is not an editable field. Audio/Video The network capacity required for transmission of the program in Kbps. This is not an Bandwidth editable field. Maximum Video Defines the maximum video frame rate for MPEG files only. Frame Rate Using IP/TV Content Manager 2-13
  14. 14. Managing OnDemand Programs Table 2-1 Multimedia Information Options (continued) Field Description Web Presentation Sets the Web Presentation bandwidth in Kbps. The default is 256. This field only applies if Bandwidth you have selected the Transfer HTML to Browser Cache check box. Web Presentation Sets the base path for the URLs in the ASF file. You must specify the base URL if the ASF Base URL file was built using relative versus absolute URLs. Clusters If File Present is checked, the file exists on the listed server. If you select Use IP/TV, the file is only served by one or more IP/TV Servers, and the load can be balanced. If you select Use WMT, the file is only served by Windows Media Services. Windows Media Services does not support load balancing or proximity management. Auto Distribute File to If selected, the file is automatically distributed using FTP to any servers for which Play is Selected Server(s)2 checked in the OnDemand Servers table that do not already have the file present. Transfer file now Specifies file transfer to start within 5 minutes. Transfer file on Specifies the date and time for file transfer. 1 This option must be selected if the HTML pages are to be served by a server that is not configured as a Web server or is not accessible to the user’s browser. 2 Be sure not to duplicate media filenames if the file content is not identical. The IP/TV Content Manager maintains a database of information about each server in the cluster. If two servers have a file with the same name, IP/TV Content Manager assumes they are the same file. This may result in the wrong file being served. 2-14 IP/TV Content Manager User Guide

SlideCast/Web Specifies the name or IP address of the IP/TV Server assigned to play the SlideCast or Presentation Server Web Presentation. In the case of SlideCast, this server cannot be the same as the Audio/Video server unless Audio, Video, and SlideCast were all recorded to an RTP file. In the case of a Web Presentation, the server can be the same. 1 For a live-capture program, you must set video format, audio format, data rate, and frame rate to values appropriate to the video capture equipment installed on the IP/TV Server. See “Live-capture Program Settings” for a list of recommended settings. 2 This option must be selected if the HTML pages are to be served by a server that is not configured as a Web server or is not accessible to the user’s browser. 3 The start and end time of the program you are defining must be within the range of the program that contains the SlideCast or Web Presentation stream. Step 14 In the Multimedia Address Information section of the New Scheduled Program page (see Figure 2-18), specify multimedia address options. Table 2-4 describes these options. In most cases, you should accept the default addresses provided by the IP/TV Content Manager, which are based on Preferences settings.

  40. 40. Managing Scheduled Programs Assigning Programs to Channels The IP/TV Content Manager allows you to set up programs that are not assigned to any channel. However, channels offer a few benefits: • Each channel has many default characteristics. If you assign a new program to a channel, the program automatically receives the defaults. However, if you set up a program that is not assigned to a channel, you must enter much more information about the program. For example, each channel has a unique set of IP addresses and UDP port numbers. All programs assigned to that channel automatically use the same addresses and port numbers, so you need not remember which addresses (or address ranges) to assign to the program. • On the IP/TV Content Manager’s main page, programs can be sorted by channel. In a busy network with many programs having multiple repeat showings, the list of programs can become very long. Assigning programs to channels is one way to make the list easier to navigate and programs easier to locate. Refer to the IP/TV Administration and Configuration Guide for information on defining channels. Program Schedule Options For any live-capture session, it is a good idea to set the start time a little earlier and the end time much later than you expect the live-capture session to start and end. Setting the start and end times this way allows for any slip in the actual start/end of the event. When a recording is made, “dead air” at the beginning and end of the session is not saved in the file. When you decide how to schedule a program, you first must determine whether the program is a continuous or noncontinuous program: • A continuous program is “on the air” at all times. One analogy is a 24-hour news station on cable television. The news program is always on, but has no explicit start and stop time, the way a network TV program does. If you define a program as continuous, and assign it to a channel, you can still define noncontinuous programs on that channel. The noncontinuous programs simply overlap the continuous program (but are not allowed to overlap each other). Note that if the 2-40 IP/TV Content Manager User Guide
  41. 41. Creating a Scheduled Program continuous program is a prerecorded file, the continuous program restarts from the beginning when the noncontinuous program has finished. noncontinuous programs must be multicast from the same server as the continuous program that they overlap. An example of a continuous program that has a noncontinuous program overlapping it is a 24-hour news service. The news program is always on, and users can tune in whenever they want to get a news update. Suppose, though, that the financial news is always discussed for half an hour starting at 3:00 p.m., and some users want to subscribe to the financial news so that IP/TV automatically launches the program for them. You can define a noncontinuous program that begins at 3:00 p.m. and runs for 30 minutes. This noncontinuous program is a subset of the 24-hour news program, and overlaps it for that 30-minute interval. • A noncontinuous program has a start and stop time for its first showing, and possibly one or more repeat showings. For noncontinuous programs only, you can click one of the following: • Set up a simple repeat schedule, in which the program repeats after the number of minutes, hours, or days you specify. For example, the program can repeat every 24 hours, or every 7 days. Keep in mind that some intervals may fall at hours or on days when there are no IP/TV Viewer users on site to watch the program. • Set up a more complex repeat schedule. For example, you can set the program to repeat weekly on Mondays at 09:00, Wednesdays at 16:00, and Fridays at 12:00. Note If you define weekly or biweekly repeats, the “Play Program once on” date and time must be on a repeated date and time. For example, if the program starts on a Monday at 14:00, one of the repeats must be Monday at 14:00. These two choices are either/or choices. You cannot combine them for the same program. If your program needs a repeat schedule with more complexity, set as much of the schedule as you can in this page. Then, once the program is submitted to the IP/TV Content Manager and you have returned to the main page, click the Duplicate link for that program to create a duplicate of the program. You can set the remaining repeat schedule in the duplicate program. See the “Duplicating a Scheduled Program” section later in this chapter for tips on using the Duplicate Scheduled Program page. Using IP/TV Content Manager 2-41
  42. 42. Managing Scheduled Programs Live-capture Program Settings When you define a live-capture program, you must set the video format, audio format, data rate, and frame rate parameters to values appropriate to the video capture card and codec (compression/decompression) used by the IP/TV Server that will capture and multicast the program. See “Audio and Video Codecs Reference” in the IP/TV Administration and Configuration Guide for recommended settings for the most common codecs. Reviewing a Scheduled Program Follow these steps to review a scheduled program: Step 1 On the Scheduled Programs page, click the Review link for the program. Step 2 Scroll through the Review Scheduled Program page to find the information you want to see. Step 3 Click Scheduled Programs to return to the Scheduled Programs page. You might want to review an existing program under these circumstances: • The program description is too long to fit in the program list on the main page. • The program is scheduled to repeat more than three times. The next three repeats after the current date and time are displayed in the main list; the Review Scheduled Program page displays the entire schedule. • The program information you want to verify is not included in the brief list on the main page. The Review Scheduled Program page displays all information stored for the program. Note The Review Scheduled Program page contains the Load Plugin and Load Application buttons for publishing programs in a Web page. In order to use these buttons you must have plugins installed. See the “Using IP/TV in a Web Browser” chapter in the IP/TV Administration and Configuration Guide for more information. 2-42 IP/TV Content Manager User Guide

Step 6 Click Revise Program at the bottom of the page to send the changes to the IP/TV Content Manager. If the IP/TV Content Manager finds errors or omissions in the page, the Data Entry Errors page prompts you to return to the Edit Scheduled Program page to modify the information. When you have finished correcting the errors, click Revise Program again to submit the corrections to the IP/TV Content Manager. If the page is properly completed, you return automatically to the Scheduled Programs page. Note If you edit a program that plays a disk file, and manually enter information about the file (such as server, file name, length, or bandwidth), the IP/TV Content Manager cannot verify the information as would be the case if you use the Select Media File button. Be careful to enter the information accurately. Note Avoid changing the audio format, video format, IP addresses, or UDP port numbers assigned to a program fewer than 10 minutes before the program is scheduled to begin or while the program is playing. Changes of this nature can prevent IP/TV Viewer from displaying the program properly. Duplicating a Scheduled Program Follow these steps to duplicate a scheduled program: Step 1 On the Scheduled Programs page, click the Duplicate link for the program. Or, on the Review Scheduled Program page, click Duplicate Program at the bottom of the page. Step 2 The IP/TV Content Manager asks you to select a channel for the duplicate program.

The IP/TV Content Manager displays the Duplicate Scheduled Program page. Step 5 Scroll through the Duplicate Scheduled Program page to find the information that is different for this duplicate program.You may change any field that was entered when the original program was created. Step 6 Click Duplicate Program at the bottom of the page to send the information about the duplicate program to the IP/TV Content Manager. If the IP/TV Content Manager finds errors or omissions in the page, the Data Entry Errors page prompts you to return to the Duplicate Scheduled Program page to modify the information. When you have finished correcting the errors, click Duplicate Program again to submit the corrections to the IP/TV Content Manager. If the page is properly completed, you return automatically to the Scheduled Programs page. You might want to duplicate an existing program under these circumstances: • You are responsible for entering and managing many programs, and the information for all of them is nearly identical (perhaps only the title and description are different). Rather than entering the information again for each new program, you can duplicate a similar program and only change a few fields. • The repeat schedule for a program is so complicated that the available repeat schedule choices does not allow you to set all the repeats at once. Set as many of the repeats as you can in the original program, then set the rest in the duplicate. Using IP/TV Content Manager 2-45
  46. 46. Recording Scheduled Programs Recording Scheduled Programs IP/TV allows you to record a scheduled IP/TV program and save it in a media file on the local disk of an IP/TV server. This feature is usually used to record content that is acquired through live-capture for playback at a later time. Two factors determine which file format is used to save the live-capture content: • If the live-capture data stream is MPEG1 or MPEG2, and if the same server is used both to capture the data and record it to a file, the file format must be MPEG (that is, the file must have an extension of .mpg). • If the live-capture data stream is not MPEG1 or MPEG2, or if the live-capture server is different from the recording server, the file format must be RTP (that is, the file must have an extension of .rtp). Unlike MPEG files, RTP files can only be used by IP/TV Server as the source for an IP/TV program. RTP files cannot be opened with a conventional video decoder. To view an RTP file, you must run RTPViewer on the IP/TV Server where the recording is saved. Refer to the IP/TV Administration and Configuration Guide for more information. To display a list of all scheduled recordings, click Recordings on the IP/TV Content Manager main page. The Recordings page is shown in Figure 2-20. For each recording, the information displayed includes the name and description of the program to be recorded, the name of the source server, and up to three dates and times at which the program is scheduled to be recorded. 2-46 IP/TV Content Manager User Guide
  47. 47. Scheduling a Recording Figure 2-20 Recordings Page For each recording, the following links are available: • The Review link takes you to the Review Recording page (see “Reviewing a Recording”). • The Edit link takes you to the Edit Recording page (see “Editing a Recording”). • The Delete link takes you to the Delete Recording page (see “Deleting a Recording”). Scheduling a Recording This section describes the procedure for setting up a recording. It has two steps: • Creating a multimedia data stream for the recording, or choosing an existing program to record. • Setting up the recording. Using IP/TV Content Manager 2-47
  48. 48. Recording Scheduled Programs Creating a Multimedia Data Stream for the Recording If the content you want to record is not already defined as a program, see the “Creating a Scheduled Program” section earlier in this chapter for instructions on setting up a new program. If you want to record an existing program, you need not define a new program before you can record it, since it is already defined in the IP/TV Content Manager. In addition, consider the following points: • Set the start and end time in the Schedule section of the New Scheduled Program page. For any live-capture session, it is a good idea to set the start time a little earlier and the end time much later than you expect the live-capture session to start and end. Setting the start and end times this way allows for any slip in the actual start/end of the event. When a recording is made, “dead air” at the beginning and end of the session is not saved in the file. • In the Multimedia Source section, be sure to select the Play check boxes for Video, Audio, and SlideCast as appropriate for the content to be recorded. Note You cannot record a Web Presentation stream. • In the Multimedia Address section, click the server(s) that captures the data. In addition, verify the status of the Capture Live MPEG Data for Recording to File; Do not Multicast check box. — If you are recording the program but not multicasting it simultaneously, select the check box. — If you are recording the program and also want to simultaneously multicast it, clear the check box. 2-48 IP/TV Content Manager User Guide

Step 4 In the Name field, enter a name for the recording or accept the name supplied by the IP/TV Content Manager. The default name is the same as the original program’s name. 2-50 IP/TV Content Manager User Guide
  51. 51. Scheduling a Recording Note IP/TV Content Manager permits a name up to 60 characters long. However, when the name of the program is displayed in IP/TV Viewer or in other IP/TV Content Manager pages, the name may be truncated to fit within the display area. For this reason, it is good practice to use short program names. Step 5 In the Recording Information section, enter a description of the recording or accept the description supplied by the IP/TV Content Manager. The default description is the same as the original program’s description. The maximum number of characters permitted in the description field is 512. Step 6 In the Recording Schedule section (see Figure 2-23), the default recording schedule is the next showing of the program that ends after the current date and time, plus any repeats scheduled for the program. Accept the default schedule, or override it by changing the information in any of the editable fields. Using IP/TV Content Manager 2-51
  52. 52. Recording Scheduled Programs Figure 2-23 Recording Schedule Section of the New Recording Page Step 7 In the Recording Instructions section of the page (see Figure 2-24), specify whether the recording includes the video and audio portions of the program. By default, all the data streams included in the program itself are enabled for the recording. However, you cannot record a Web Presentation or SlideCast stream. 2-52 IP/TV Content Manager User Guide
  53. 53. Scheduling a Recording Figure 2-24 Recording Instructions Section of the New Recording Page Step 8 Enter the full path name of the file in which the recording is to be stored. The file extension must be .rtp or .mpg. The RTP file format is only used for recording IP/TV programs, and is optimized for multicasting over a network. The MPG file format is used for local recording of live MPEG1 or MPEG2 data streams. Step 9 Specify whether an existing file by the same name should be overwritten. If this check box is selected, unique filenames are generated to prevent the first recording from being overwritten by a later recording of the same program. Note that if you choose not to overwrite repeated recordings, these files occupy a great deal of disk space and may quickly fill the server’s disk drive. Step 10 Click a server from the list or enter the name of a new server. This name must be the name of the server that performs the recording and stores the file on its local disk drive. Note that the live-capture server or the server serving the program cannot be the same as the recording server, unless you are recording an MPEG1 or MPEG2 data stream to an MPG file.

  57. 57. Using the Question Manager Using the Question Manager The Question Manager is a text-only feedback mechanism that allows users to submit questions to the moderator of a scheduled program. The moderator can display the questions that apply to the program, sort the questions, answer the questions as part of the presentation that is being shown, export the questions to be stored or manipulated in an external spreadsheet or database application, and delete the questions after the program is complete. Question Manager is useful for environments such as distance learning and training. It allows remote users to participate in the Question and Answer portion of the presentation. The Question Manager function applies to scheduled programs, but not to on-demand programs. Note This participation is not fully interactive. The Question Manager is a unidirectional tool; it sends questions to the program’s moderator, but does not return answers to the user. Answers must be provided as part of the program content. Enabling the Question Manager Before a user can submit questions about an IP/TV program to the program’s moderator, or an administrator moderate a program, the Question Manager function must be enabled for that program. To enable the Question Manager for a scheduled program, select the Enable Question Manager check box in the New Scheduled Program, Edit Scheduled Program, or Duplicate Scheduled Program page. An example of the New Scheduled Program page is shown in Figure 2-15. Sending a Question to the Question Manager Moderator If a user is viewing an IP/TV program that has the Question Manager enabled, the Question Manager button on the IP/TV Viewer tool bar is active; otherwise, the button is grayed out. When an IP/TV Viewer user clicks an active Question Manager button, the Question form appears (see Figure 2-26). Using IP/TV Content Manager 2-57
  58. 58. Using the Question Manager In the Question form, Question Manager supplies the user’s e-mail address and name that the user entered in the IP/TV Viewer User Information dialog box. If this information was not entered, the moderator receives the question from Anonymous. The user can change the name, enter a subject line, and enter a question. When the user clicks Submit, the question is sent to the Question Manager moderator. Questions can be submitted before the program begins. Figure 2-26 Question Form Moderating an IP/TV Program To run the Question Manager Moderator, your Web browser must have Java support enabled. (Java support is not required for users submitting questions to the Moderator.) Follow these steps to moderate a Question Manager enabled program. Step 1 In the Scheduled Programs page, click the Question Manager link in the task bar. Or, start a Web browser and go to the following URL: http://<contentmanagerhost>/iptvfiles/qmselect.htm where contentmanagerhost is the DNS name or IP address of the IP/TV Content Manager managing the program.

  61. 61. Moderating an IP/TV Program Sorting the Question List To sort the list by status, name, date and time, or subject, click the column heading to be used as a sort criterion. As new questions are submitted, they are added to the list and sorted according to the current sort criterion. Displaying the Full Text of a Question To display the full text of a question (that is, the text entered in the question box on the user’s Question form), select the question by clicking anywhere in that row. Changing the Status of a Question Initially, every question has the status “Q,” indicating that the question has not been answered. Questions may be answered in several ways. Note that none of these ways results in feedback to the person who submitted the question other than through the program content itself. During the course of the program, if the program content addresses a user’s question, the moderator can change the status to “A,” meaning “answered.” Or, if the program includes a Question and Answer period, and the question is answered by the presenter, the moderator can change the question’s status to “A.” To change the status of a question, select the question and click Answered. The status field for that question changes from “Q” to “A.” If the list of questions is long, and many questions have been answered, the moderator can delete answered questions from the list by selecting each answered question and clicking Delete. Deleted questions disappear from the moderator’s question list, but the IP/TV Content Manager does not purge them completely until it deletes the program itself. To purge deleted questions before the IP/TV Content Manager deletes the program, the moderator can click Purge All Deleted. Using IP/TV Content Manager 2-61
  62. 62. Using the Question Manager Displaying Questions in Table Form At any time, the moderator can display the questions for the program in table form by clicking Show All. The List All Questions page appears (see Figure 2-29). This is a convenient form to print out and give to the program presenter, so the presenter can answer the questions during the Question and Answer portion of the presentation. The list displayed on the List All Questions page includes all questions for the program being moderated, and whether their status is asked, answered, or deleted.
