Video System

The video capture system consists of cameras and a video server which converts the video image into an IP stream for transport over the network. The system uses multiple camera angles to provide an environment that simulates physically being in the room as opposed to a videoconference's talking-head delivery. The placement of the cameras is a critical piece to providing a compelling environment for collaboration and is covered in more detail in the Room Configuration section.

Camera Placement

The size and intended use of the room will determine the number of cameras and their placement. For a typical node location, three cameras are used to provide coverage of the environment.

  1. Presenter - This camera is used to provide a front view of the participants or presenter and should be placed facing the audience and in as direct a line of site as possible to the projected image. This placement will give the impression of the local group looking directly at the remote group when the remote groups image is placed on the projection wall. This image will also be the main focus point for the remote audience and provides the most direct interaction.

  2. Primary / Secondary Audience - This camera is used to give an additional view of the audience and more detail of the surrounding environment.

  3. Projection Wall - This camera provides a view of what the local users are viewing to the other participants in the session. This also provides a view that completes the image of the room.

  4. Additional Cameras - Additional cameras may be added to provide better coverage of the room or help to complete coverage of the space provided.

The cameras are connected to the Video Server via "S" Video cables to the Wintv 125 Dbx TV Stereo 125 channel video card. The order in which the cameras are connected to the video cards is not important for setup but should be annotated for use during operation.

Note: See the camera's operation manual for operating instructions.
