camera presets

:

Allow you to pre-define camera angles, locations, and distances and store them into a videoconferencing system. Many systems are so simple to use that it's basically just four steps: 1) Use the remote or control to select a camera to set (Can include the remote camera at the other end of your call!); 2) Position the camera by using the arrow buttons and ZOOM control to the desired location and distance; 3) Press SELECT or whatever the command is; 4) Confirm selection. Often a number is assigned to the preset. During a videoconference, you need only press that preset number and the camera will automatically change to the location and distance you preset.

Certified Videoconferencing Engineer

codec

:
A device or software that enables compression and/or decompression for digital video and audio

content

:
Any data such as presentations, spreadsheets, and schematics that can be displayed and presented to far side endpoints, or received and view on the near side

continuous presence video

:
A feature in multi-point conferencing that allows the video endpoint to see images from multiple video endpoints at the same time. All parties remain continuously visible or 'present' for the duration of the call and the user can have control over the screen layout. In comparison, Voice Activated Switching only allows the user to see the current speaker on full screen while the rest of the participants remains hidden. Continuous Presence is better suited for tam collaboration since it allows participants to see the reactions (body language) of all participants, not just the speaker.
