DVC Connections & Equipment

Each SCPS DVC facility is equipped with a VTEL codec computer, which enables us to make the videoconferencing connection.  The codecs run on the Windows 98 operating system.  The software that enables us to establish the connections is Galaxy (Vtouch), which must be running after the codec is booted up into Windows.  Normally, the Vtouch program will already be running when you come to the facility. 

Connections are made in two ways, either a bridged call (multiple sites) or a point-to-point call (two sites only).  With bridged calls, you will see the last site that was talking and yourself.  The bridge switches to the viewable site according to the level of audio and duration of audio received.  It takes about five seconds for the bridge to switch viewable sites.

There are three protocols in which calls can be established.  They are as follows:

ATM – Asynchronous Transfer Mode – This is the statewide network (Network VA) that is the most often used in conferences with other statewide agencies.  It is also the most practical protocol to use.

Integrated Services Digital Network – This protocol is used for most connections with non-state and foreign organizations.  The cost is higher and is adjusted depending on which site establishes the call. Although this protocol is relatively free, the connection for these types of calls is not as reliable and bandwidth is shared with all other network users.  

In some of the facilities the codec is also the computer used for Power Point presentations (see appendix).  These computers are Pentium III 500mhz machines, but please keep in mind that they are also running a memory intensive videoconferencing program as well.>  So in these rooms Power Point presentations must be kept on a very basic level.

Monitors

Each room is equipped with two or more monitors.  The monitors serve three basic functions while in a conference:

Ability to see video signal that you are sending to remote site(s), which is typically on the right side monitor.

Ability to see video signal coming from the last viewable site.

Ability to hear remote site audio via monitor speakers.  The volume can be adjusted through the codec Control Tablet and the volume controls on the monitor.

The monitors should always be on the “Video 1” source and should only need to be powered on for a conference.  If you are not in a videoconference call and the monitors are turned on, they should all display the same local video source.

NOTE:  The monitors are not connected to the local cable system or satellite therefore, DO NOT change the channel to look for programs.

Microphones

Microphones enable remote sites to hear what you are saying.  If no microphones are on, you are in essence muted to all remote sites.

Instructor microphones:

  1. Stationary “One Touch” microphones – These are desktop microphones that have a press to talk button (Touch). Once the button is pressed on these microphones, the microphone stays on until the button is pressed again.
  2. Lapel (clip on) Microphone (available in certain rooms only – see appendix) These microphones are clipped on to a tie/coat/blouse approximately six inches below chin level. Instructions on how to use these microphones are given in the room where they are used.

 

Student microphones:

  1. In some rooms they are “One Touch” microphones – These are desktop microphones that have a press to talk button (Touch).Once the button is pressed on these microphones, the microphone stays on until the button is pressed again.
  2. In some rooms they are “Momentary Touch” microphones – These are desktop microphones that have a press to talk button (I/0). They must be depressed the entire time the student wishes to talk.  The microphone cuts off automatically once the student stops pressing on the button. 

It is important for the student to use the microphones even if the instructor is in the same room, so that the remote students/participants can hear any questions/comments.

Control Tablet

There is a tablet connected to each DVC unit.  The tablet is a graphic interface that simplifies any modifications that an instructor/participant may need to make during a conference.  The tablet layout is included in the back of this manual.  If you intend to teach out of one of the classrooms, it is highly recommended that you familiarize yourself with the tablet’s specific functions in the room that you will be teaching in. 

The Basic functions of the tablet are:

  1. Changing local video source – This enables the user to switch outgoing video between cameras,    VCR, and computer
  2. Adjusting local video (instructor or student camera)  - Position, zoom, focus, and iri
  3. Adjusting incoming video

The Advanced functions:  require additional training in the use of the conferencing equipment. In some point-to-point connections the instructor can also control the remote site cameras.

Dial/Hang up controls are only used by the technician


Video Sources/Cameras

These are what enable sites to see each other and what they are presenting. 

The main video sources are:

  1. Instructor/Student cameras – Enables sites to see people involved with the conference.
  2. Document cameras (see Appendix) – Enables sites to view materials such as transparencies, overheads, pictures, and various other items.
  3. Computer source – Allows for software such as Power Point, internet, and other PC based applications to be shown.

 

See Appendix for other room specific camera information.

DVC Etiquette

Video is a microscope…

Because each isolated shot allows the viewer to study the presented image in detail, awkwardness is readily identifiable - RELAX. Be friendly and be yourself. When you look directly into the camera lens, you are looking directly at the students, eye to eye. Don't forget to smile and be friendly.

When you are speaking don't distract the student from the content of your message by making errant visual cues that break the viewer's concentration. Scratching your ear, adjusting your hair, etc. may appear unsophisticated if you are the lone subject on the screen.

When answering students' questions from off-Grounds locations, look at the camera in front of you. Speak in a normal voice. Students can and will interrupt at any time during class unless you plan a specific time for questions.

The on-Grounds students have microphones located on the tables in front of them. Students MUST use these microphones whenever they ask questions. If they don't the off-Grounds students cannot hear the question that was asked thus making the answer hard to understand.


II  What to wear

The following are suggestions for appropriate clothing for DVC:

 Do Wear

- Solid colors; bright or subdued
- Street make-up for women (none for men)
- Pastel shades or off-white for shirts and blouses
- Your usual eyeglasses
- LADIES: Avoid frosted lipsticks, they have a tendency to turn blue on video

Do NOT Wear

- Avoid dense prints or patterns (including plaid and herringbone)
- Black, WHITE, and very shiny fabrics
- Overwhelming scarves and ties
- Noisy jewelry (interferes with clip on microphones)
- Loose change in pockets (same as above)
- Shiny or reflective jewelry (dull finishes like pearls are fine)
- Hats with wide brims

Remember, you are the center of attention, not your wardrobe.

III   Lecture notes/Documents/Power Point

We have found that 30 point Helvetica type in bold face works best for printed lecture notes that will be displayed using the Elmo camera.  Print the notes in landscape mode (11x8.5) if using a laser printer; portrait mode (8.5x11) doesn't allow an entire page to be viewed at one time.

The same guidelines that apply to text also apply to using Power Point presentations in a DVC.  Transition animations can be used with Power Point presentations, but are NOT recommended.  This is due to the possible difference in speeds of computers and they often do not flow properly when changed to video. 

When Power Point is to be used, the presentations should be brought in on floppy disk or CD-rom. 

Presentations can sometimes be transferred to the room via email or FTP.

IV   Elmo

All of our DVC facilities have document cameras (figure 1), or as we call them Elmos.  Elmo cameras are used similarly to overhead projectors without the projection.  Documents and transparencies are placed on the base of the unit for the camera to view. 

There are several different controls on the front edge of the Elmo units (Figure 2):

1.      LAMP These buttons turn on and off the upper (a) and base lights (b) on the unit 

a.      The upper lights are used to illuminate paper documents.

b.      The base light is used to illuminate transparency type materials

 

Instructors should checkout best lighting settings for their presentations

before class begins!

2.  INPUT  These buttons control what is being sent from the Elmo unit to the DVC unit/monitors.  Normally you should not need to worry about this set of buttons unless an extra video device of some type is needed for your class/conference.  For typical Elmo usage the “Internal” button should be the one activated.

3.  POSI/NEGA  This button is only used in unusual circumstances.  “Posi” shows your document just as you normally see it.  “Nega” shows a negative image of your document.  Normally you will not need to worry about these buttons.

4.  COLOR/B&W  This button controls whether the output of the Elmo is in color or black and white.

5.  ZOOM  These two buttons (Tele/Wide) control the camera on the Elmo.  Tele zooms in on the document pad and Wide zooms out from the document pad.  These buttons can be useful when dealing with small text and  when you want to closely show details on an image or overhead.

6.  FOCUS  These buttons (N/F/AUTO) can be used if your documents look out of focus and blurry on the screen.  The N and F buttons are the manual controls used to focus the camera.  The Auto button activates the auto-focus of the camera and the camera will automatically try to bring your document into focus.
