Video TeleConferencing (VTC) allows people to attend meetings held in multiple locations by sending a real-time TV-style signal between two or more rooms. This connection can be used for talking, computer presentations such as PowerPoint slides, and video sources such as VHS tapes or DVDs.

The most common way to conduct a multipoint video meeting is for each participating video system (meeting room, desktop, etc.) to connect to a single bridging device called a multipoint video bridge or MCU. Video bridges are available in two basic form factors: embedded within the video endpoint itself, and as a stand-alone hardware device.
While MCUs embedded within video endpoints can provide a cost-effective means to host high-quality multipoint meetings, they support only a limited number of participants (typically four) and provide a limited feature set. For these reasons, CIT hosts all meetings on a dedicated video bridge. Currently the NIH Video Bridge has the capability of supporting up to 120 simultaneous video connections and up to 59 individual conferencing layouts.

Customer Benefits

VTC allows experts from all over the world to communicate with and learn from each other, while avoiding the high costs and scheduling problems of travel. Additionally, a group can attend lectures, meetings, and conferences without leaving the office simply by setting up VTC in one room, where viewers can remotely join the distant events via a full-screen television experience.
CIT has upgraded our dedicated video bridge to service the HHS/ NIH community. The following are just a few of the new features that the NIH Video Bridge offers:
  • Share content to show every participant your slides, spreadsheets, or documents
  • Display all participants at all times with new layouts (Hollywood Squares and others)
  • Provide IP connectivity for lower-cost connections
  • Present enhanced, near high-definition, video quality for all participants
  • Conduct a public forum without renting a hotel ballroom
  • Record live meetings for on-demand viewing
  • Host virtual meetings for town halls, councils, or classes

Customer Market

This service is available to all NIH customers and to other customers outside of NIH.
