LB Guide to Produce Lectures

1. Get an account at BMRC with the proper rights
2. Run the production tool (ALPS)
3. Select the lecture you want to produce
4. Produce the lecture
5. Provide a link to the LB-produced lecture
   

   1. Get an account at BMRC with the proper rights [TOP]

   • Ask BMRC's sysadm, Peter, to create you an account
   • Important detail: you must get proper access rights to BIBS: you should be included in the PostgreSQL lb_producers group. While we decide should we create it and we do create it, the bibs_producers one should be more than enough.
   
   

   2. Run the production tool (ALPS) [TOP]

   • Log in dogbert.cs.berkeley.edu. We prefer you to use a secure login shell (e.g., SSH).
   • Change to the alps directory

           > cd /n/plateau/project/lb
     		

   • Get sure that your display is forwarded to your box

           > setenv DISPLAY your_pc_name (for tcsh shells)
     		

   • Check that you have an X client (you may want to use eXceed if you have a Windows box), and it is willing to accept windows from dogbert (you may want to permit dogbert access to your X client using xhost )
   • Execute the application

           > ./alps.tcl
     		

   • A new window should pop up in your display (figure 1)

   3. Select the lecture you want to produce [TOP]

   • Select first the class (figures 2 and 3), then the semester (figures 4 and 5), and then the specific lecture or seminar (figures 6 and 7). Once you have find the lecture you want to produce, click over the Ok button at the bottom right corner.
   • The traffic-like lights to the right of the window (figure 8) report which parts of the information needed by the Lecture Browser are already available. They refer, up to bottom, to the video file, BIBS database information, timings, image locations, search indexing, and published mark respectively. A lecture is not published until all the six sources of information have been filled, and therefore the six lights appear on green.

   • If either the class or the semester in which it should appear the lecture you are trying to produce, are not present, you just cannot produce it. For security reasons, the ALPS tool doesn't permit adding a new class or a new semester in a given class. You should contact any of the BIBS administrators and request his help.
   • If both the lecture's class and the lecture's semester are present but the lecture you want to produce is not, then you have to select the "-- New --" lecture entry (figure 9). Only those lectures whose video appears in the lecture and semester directory, and those that have a valid BIBS entry will be listed.
   
   

   4. Produce the lecture [TOP]

   • After having press the Ok button, a new window should pop up in your display (figure 10)

     Figure 10

   • Click on the "Talk" or "Speaker" notebook entries to check the lecture information and eventually modify it. Figure 11 shows the talk information (title, date, URL, and abstract). Figure 12 shows the speaker information (name, URL, affiliation, and affiliation URL).
   • Click on the "Video" notebook entry to check the information about the video (figure 13). This information includes the video URL, the start and end times, and the dimensions.
   • The next step is adding the slide and timing information. Click on the "Slides" notebook entry your display (figure 14)

     Figure 14

   • Click in the "Edit Images Information" to fill the information about the slide images.
   • Click on the "Edit Timings" button to include the information about the timings.
   • Click on the "Search" notebook entry (figure 15). If the slides have been obtained by exporting a PowerPoint (either 97 or 2000) presentation to HTML, just press the button "Index". If your slides are in a different format or you want to include more information than just the slide texts go to the new text page.
   • Once all the information has been included, click on the "Publish" notebook entry and there press the "Publish" button (figure 16).
   • Finally the lecture has been produced!
   
   

   5. Publishing a link to your lecture [TOP]

   • Once you have the lecture marked as published, the last step you may be willing to do is to include a link to the produced lecture in your webpages.
   • You need to add two HTML lines:
     • one for every page where you want to include links to the lecture browser. This line must be the following one:

         <script language="JavaScript" src="http://bmrc.berkeley.edu/projects/lb/open_window.js"></script>
       			

     • one for every link (you can add more than one LB link in the same page).

         <a href="javascript:openWindow(39,13,83);">the link</a>
       			

   • For example, this link permits you to go directly to one of our published lectures (Fall 99 Chem1A lecture 26).
   • NOTE: The three numbers that you have to plug in the openWindow function are the three id's of every lecture (prog, group, and inst). You should have written them up during the publishing process. Nevertheless, should you want to know which are those numbers for a lecture you want to link to, go to the BIBS webpage and look for the lecture. Once you find it, you'll see three numbers composing the URL. Those, in exactly that order, are the numbers.
   • For example, if you look for the Fall 99 Chem1A lecture 26, you'll end up at: http://media2.bmrc.berkeley.edu/bibs/instance.cfm?prog=39&group=13&inst=83
