NetMeeting can be used to present a meeting in which virtually any number of people logged in to other computers can see what you're doing when you run an application on your computer. This works in a manner very similar to that used by PcAnywhere. That is, when you're running the application, the people watching you see a window on their PC that shows the application window just as you see it. When you move the mouse, for example, they see the mouse move on their screen. You can set things up so that the people in your audience can only watch what you're doing without being able to take control of your application. Or, if you trust your audience, you can allow them to use your application just like they were in front of your PC.

Although this note concentrates on how to share a PowerPoint 2000 presentation it's important to realize that you can use NetMeeting to share any Win32-based application.

To create the meeting,

Start the application you want to present in the meeting the way you would normally.
Start NetMeeting. (On Windows 2000 the NetMeeting icon is located in Start->Start Programs->Accessories->Communications->NetMeeting).
Click on the "Call->Host Meeting..." item. This lets you give your meeting a name, and a password if you want.
Click on the "Tools->Sharing" item. This brings up a window asking you to specify the application you want to share. Pick Microsoft PowerPoint.

That's all you have to do.

When people want to join the meeting to see your PowerPoint presentation they first need to know the name of the computer you're running NetMeeting on. Then they need to start NetMeeting on their computer. They DON'T have to start PowerPoint. Using NetMeeting they should click on "Call->New Call" and then give the name of the computer that you're on in the "To:" box. Then, the should click on "Call". When they do this you'll see a pop-up window on your screen asking if you want to accept their call. Click on "Accept". (You can configure NetMeeting to automatically accept calls so you won't be bothered having to accept calls from every member of your audience). Once a person has been accepted they will see a new window on their screen showing the same thing that your PowerPoint window is showing. As you flip through slides every member of your audience will see the same flips. When you're done with your presentation click on the "NetMeeting Call->Hang Up" choice. This will cause all the audience members to be dropped from the call.

That's it.

How do I use the Sony projector?

These instructions will be automatically displayed on the laptops directly connected to the projectors when someone logs in.

1. Lower the screen, the controls are on the wall to the left of the screen.

2. Turn the remote ON (upper left) point the remote at the screen, then press the green power on button(upper right).

3. The orange LED on the projector should change to green.

4. Make sure the projector is set to INPUT-B to display the laptop screen.

5. When finished, power off the projector by pressing the green button (upper right), switch the remote to OFF ( upper left ), and raise the screen.

Replacing the bulb

The bulb is a Sony LMP-P201, which runs around $225-$300 each. Spare bulbs are in the 540 A/B projection booth.

To replace the bulb in the 540A/B projector requires taking the projector off the ceiling. To do this, push the wires up inside the channel and then undo the 4 smaller bolts and loosen the two larger bolts. Two people make this a much easier proposition.

Undo the panel at the bottom and then replace the bulb

Clean the air filter

Rehang the projector and plug it in

Reset the hour timer by putting the machine into standby mode (unplug it and replug it) Then, on the projector itself, hit reset, left arrow, right arrow, enter within five seconds.

540 A/B Conference Room Projector, North Wall

10/06: previous bulb lasted 165 hrs.
4/09: previous bulb lasted 1048 hrs

DOP Center Forum West Projector

4/09

Previous bulb lasted 358hrs

The lamp reaches the end of its life after about 1500 hours for the STANDARD setting, or about 3000 hours for the LOW setting in the LAMP MODE.

The bulbs contain mercury and should be disposed of by having the Hazardous Materials unit of Environmental Health and Safety pick them up as follows:

One must first establish a chemical waste recharge account. This is done by completing a pdf on the EH&S site (http://ehs.berkeley.edu/recharge.html). Completion of the pdf entails getting a fund number from an RSO, who must also sign the pdf once you have filled it out. Put yourself as the contact person for this pick-up.
Fax the completed pdf to EH&S at 643-7595. Keep a copy.
After a couple of days, find the recharge account you initialized by going to http://srs.ehs.berkeley.edumplSorg.html and searching for it based on the 'org' code (second group of digits in the chart string the RSO gave to you).
Look for your P.I. in the table that comes up as the result of your search and click on the chart string next to the PI name. (The chart string should be the same as the one you used to establish the account initially.)
You will have the option of either starting a new Materials Packing List, or,if you've been working on one previously, returning the one you'd already started.
Fill out all the fields on the packing list (Building, Room, Your Name, etc.)
Click on the "Add New Item" radio button in the lower left corner.
Since this is just for projector bulbs, you have only one item to list.
In Item field, put something like 'expired lamp unit for Sony projector'
Click 'Save this Item' which will return you to the packing list.
Click on 'SUBMIT this eMPL'
Print the packing list, sign it, and tape it to the box of spent projector bulb(s).

Staff from EH&S will come looking for you and for the bulbs to be picked up.
If they don't come around within a week, call Phil Kruse at 3-6384 to find out when they are planning to come pick up the bulbs.

What about Presentation Capture?

Presentation Capture is fairly complex, see the Netshow page in the Video GSRC Workgroup for details.

The basic idea is that we should be able to capture presentations for later broadcast. This is different from real time video conferencing in that the presentation is stored on a video server and broadcast on demand.

An example can be found at http://www.gigascale.org/pubs/talks/2002/berkeley/ but you must be a GSRC member to view the talk.

Types of captures

Audio only

Record an audio file.

Audio and Video

Record a streaming media file or an mpeg

Audio and synchronized Powerpoint slides

Audio, Video and synchronized Powerpoint slides

This is fairly tricky, but it is what we do for the GSRC Workshops Currently, we use NetShow, see the Netshow page in the Video GSRC Workgroup for details.

Requirements

Any solution must:

Run under Netscape - Powerpoint 2000 has a video capture feature that does not work under Netscape, the html files that are exported use dhtml, which is not displayed properly under Netscape Communicator

Run under Linux - Many students use Linux

Be easy for students to set up and operate

How do I use the Sony PCS Conferencing hardware

Point to Point Data Conferencing with the Sony PCS6000

Equipment:

Remote Commander - primarily used to navigate Sony PCS 6000.
Wireless Keyboard - can be used for inputting characters and demonstrating applications.

Where can I view the Teleconference presentation by Christopher Hylands and Marvin Motley?

On August 28, 2002 Christopher Hylands and Marvin Motley provided a 40-minute presentation and demonstration of current teleconferencing software. This presentation was captured and is available for viewing at:
http://www.gigascale.org/pubs/talks/2002/berkeley/

Also captured was post-presentation discussion about the use of teleconferencing. The audio during the discussion is not very great, however most of the discussion can be followed. Since the discussion was interesting it has been included.

Making Talks Function in Latest Versions of Browsers

This section addresses the procedures associated with updating talks so that they function in the latest versions of the various browsers. (ie Mozilla, Netscape, and I.E)

Re-Editing Talks So The Slide Flips Function in Mozilla 1.x / Netscape 7

This procedure is used to edit our ASF files so that the talks will function in Mozilla 1.x, Netscape 7.0 as well as IE 6.0+

1. Make a local copy of the talk directory from:

\\gigavault\wwwroot\gsrc\talks\year\location

Save one unaltered copy (in case a complete reverersal is required) then created a second local copy to work on. Once the newly edited talks are successfully running on Gigavault, then both local copies can be deleted.

2. Start the Windows Media File Editor (version 9.00.00.2926) and open the asf you would like to edit. In order to open .asf files you will need to scroll through the "Files of type:" and select "ASF Files (*.asf)"

3. From the file menu select "Move scripts to Header". You will be prompted to create a new file. Select "ASF File" from the "Save as type:" menu, and save the new file as "xx-new.asf", with xx representing the numbered file name. This creates a new file which has the script information in the header of the file.

4. From the file menu select "Export header file..." Save the file as "slide-times.TXT". It will default to the proper location (i.e. the directory you are working in).

5. Open the newly generated text file ("slide-times.TXT") in notepad or WordPad.

6. Edit the URL's called in the script commands using the "edit>replace..." command. For instance, you might see the following:

<Scripts >
<Script Type="URL"
Command="http://10.0.0.11/gsrc/talks/2002/neworleans/01/01/slide2.gif"
Time="475260000" />
<Script Type="URL"
Command="http://10.0.0.11/gsrc/talks/2002/neworleans/01/01/slide3.gif"
Time="2004020000" />
<Script Type="URL"
Command="http://10.0.0.11/gsrc/talks/2002/neworleans/01/01/slide4.gif"
Time="3204760000" />

You will want to change all of the URLs so that they look something like:

<Scripts >
<Script Type="URL"
Command="11/slide2.gif"
Time="475260000" />
<Script Type="URL"
Command="11/slide3.gif"
Time="2004020000" />
<Script Type="URL"
Command="11/slide4.gif"
Time="3204760000" />

The URL you will be altering to depends entirely on the name of the directory of each specific talk. If the talk is in File "11", then that's the name of the file it should be directed at.

NOTE: Some of the browsers do not like to be stepped back in their referencing. For instance, a relative pathname like ../../01/01/slide2.gif will not function in certain browsers, for this reason the Slides themselves will likely need to be moved into the inner directory of each talk and the link made as simple as possible, for example "11/slide2.gif". Confused? Here's the history: In order to achieve a smooth transistion between speakers the talks are merged. In general the merged talks occupy the first few directories, say 01, 02, and 03.(This is not necessarily true in earlier talks, which may be numbered without such order) Each individual speaker also has his/her own directory which serves as the primary location for talk-specific files, like html versions, PDF versions, etc. The individual's directories begin at directory #11, 12, 13, etc. (This is not necessarily true in earlier talks, which may be numbered without such order). When the talks were originally placed online, the ASF files were edited down for each speaker and placed in the individual's own directory; however the slide flips would point to the slides within the merged talk directory. So a talk for Jan Rabaey might be inside directory 12, and when played online it would search for the .gif slide images 1.gif-14.gif inside of directory 01/01. Alberto's ASF would then reside in 13 and call for slides 15.gif-40.gif inside of 01/01 directory. Only 3-5 talks can be successfully merged before the ASF files become cumbersome, so once a file became too cumbersome a new merging was made and a new directory created, thus talks following Alberto, might be grouped together into directory 02. For instance Randy Bryant might follow Alberto, his talk, "14.asf" would be placed into directory 14 and his asf file would retrieve the GIF files Slide1.gif-Slide18.gif from the 02/02 directory. Tim Cheng spoke next and his asf file, "15.asf" would access the GIF files Slide19.gif through Slide 38.gif in the 02/02 directory. In order to re-edit the asf files so that all the browsers can easily locate the GIF images, the GIF files need to be copied into the individual's talk file, and the Header Script command also requires editing so that it correctly locates the moved GIF files. So after the header is edited (as above) you will need to copy corresponding GIF files into the speaker's individual file, for instance, in the case of Tim Cheng above, moving the gif files "Slide19.gif" through "Slide38.gif" from the 02/02 directory into the 15/15 directory. Additionally, the Slide prior to the first one mentioned in the header script will usually need to be moved, in this case, "Slide 18.gif." This is because the initial image is often not mentioned in the header. So now to step 7.

7. Another edit you will need to make to the header is adding the initial slide flip which always begins at Time="0"

Before Change:

<Scripts >
<Script Type="URL"
Command="11/slide2.gif"
Time="475260000" />
<Script Type="URL"
Command="11/slide3.gif"
Time="2004020000" />
<Script Type="URL"
Command="11/slide4.gif"
Time="3204760000" />

After Change:

<Scripts >
<Script Type="URL"
Command="11/slide1.gif"
Time="0" />
<Script Type="URL"
Command="11/slide2.gif"
Time="475260000" />
<Script Type="URL"
Command="11/slide3.gif"
Time="2004020000" />
<Script Type="URL"
Command="11/slide4.gif"
Time="3204760000" />

8. Once the Header text file is edited you will then re-open the original ASF file in the Windows Media File Editor program and import the edited header file, using the "Import header file…" command from the file menu. Save the file as something like "z11.asf" so as not to confuse it with any other asf files.

9. Repeat this procedure for each of the talks in the workshop.

10. Once all of the changes above are completed you may run the new "mkasx.sh" file which regenerates all the HTML files for a given set of talks so that the code will function and display properly the newly edited talks.

11. Copy over to Gigavault the newly edited ASF files, placing them in the proper directory.

12. Check all the talks in Mozilla, Netscape 7.0 and IE. Make sure the slide flips are occurring.

13. If everything's working you can delete the local versions of the talks.

14. The next step will involve adding the indexing to the talks.
