NASA TV

As an example of a useful application of Public CU-SeeMe access, let us look at receiving NASA TV directly over the Internet. This is of particular interest when live events such as Space Shuttle Missions are being transmitted, but there are often televideo presentations of educational interest even when this is not the case. In this application one typically uses CU-SeeMe in a receive-only mode by connecting to a reflector site.
Example 1: NASA TV

If you stored the master list of nicknames, as described in the previous section, double click its icon to open the file and look through it to find one of the "(USA) NASA TV at ..." options (there are several). Go to the "Conference" pulldown menu, select "Phone Book", and click the "New" button. Enter the name for the site you chose and click "OK". Then enter the IP number shown for this site in the master list in the "IP Address or Hostname" box and click "Save".

If you do not have this master list file, try accessing the NASA site at NASA Lewis Research Center. Open the Phone Book window (as above) and click "New". Enter "NASA Lewis Res Ctr" and click "OK". Then enter 139.88.27.43 in the "IP Address or Hostname" box and Click "Save".
In either case, be certain that "Recv Video" is checked, but "Send Video" is NOT checked, and click "Connect" (see adjacent figure).

A window similar to the one shown on the left should pop up with NASA programming in it. If it does not, go to the participants list in the main CU-SeeMe window and look for an entry "NASA TV" under "Visible Users"; see figure below. (You may need to first click on the box next to this category title, if the list is collapsed.) Selecting that entry will open the window. This participants list also shows those presently logged into NASA TV through this server, with their status. We showed an example of such a list in the earlier general discussion of CU-SeeMe.

Example 2: Ask a Scientist

Another application of CU-SeeMe that may be of interest for classroom application is the Ask the Scientist CU-SeeMe televideo conference program, with reflector at 128.42.249.172. A schedule of events is available during the school year, and you may subscribe to a mail list.

Reflector Responses

Reflectors are not always on, or may transmit an initial "message of the day" still image when they are on. Two typical responses, one giving a "message of the day" timeschedule and one indicating that the reflector is not operating (or at least not accepting connections) are shown in the following figures.

If you get a response like the first one (a connection, but no video window) look at the participants list in the main CU-SeeMe window. There will normally be a window listed there that will display when it is selected explicitly. For example, see the "NASA TV" entry in the participants list of the main window shown above in an example. Of course, if you get a response like the second one, you are out of luck for the moment since the relector is not receiving connections.
