Video & Teleconferencing

Video Conferencing

A videoconference is two-way fully interactive communication using specialized electronic equipment over IP and ISDN networks.  Videoconferencing has evolved from using expensive ISDN networks and expensive videoconference hardware to very sophisticated high definition videoconference systems using a standard IP network connection.  The largest manufacturers of videoconference equipment are Polycom, Cisco/Tandberg, Sony, and Lifesize.  A basic videoconference system includes a high definition video camera, a codec which does all the video processing, a monitor (either flat panel display, projector, or plasma), a microphone, and a speaker.  Although a videoconference system is considered a network device, the standards for H.323 IP videoconferencing throughout the world are established by the International Telecommunications Union (ITU).  This international standardization allows for one videoconference manufacturer to establish videoconferences with a different videoconference manufacturer with little concern of incompatibility issues. 

Here at Wake Forest Baptist Medical Center we have robust videoconferencing infrastructure with two Tandberg Video Communication Servers(VCS), a dedicated Cisco ASA firewall, and a Tandberg Management Suite handling all videoconference call routing and call management within our network and video calls wanting to enter our network.  A Codian high-definition multipoint control unit (MCU) and our IP-to-ISDN gateway provide the capability to host large videoconferences across IP and ISDN networks without having to use a third party service.  Most of our videoconference systems are Polycom with a few Tandberg systems being used.  Our network infrastructure also supports the use of Cisco Jabber which is a videoconferencing software application which runs on Windows XP, Windows-7, MAC OS, and the iPad.  Deployment of Cisco Jabber is limited at this time to clinical telemedicine applications and researchers with videoconference mobility requirements. 

The Medical Center has many conference rooms and classrooms equipped with videoconference equipment. If you have any questions about videoconferencing, would like to schedule a video conference, or need immediate assistance with your videoconference please contact:

Audio Conferencing

Audio Conferencing or teleconferencing is a two-way interactive audio communication using electronic equipment such as your mobile phone, office telephone, or audio tabletop conference phone.  There is no video or visual media sharing in a traditional audio conference.  Audio conferences can involve two or more participants or be very large and involve many, many participants who all dial into a conferencing bridge or conferencing service where an access code or PIN number is required. 

 

If you are an employee of the Medical Center and frequently schedule large audio conferences, you can request an audio conference account be established for your use by contacting Elyse Ferguson in Information Services. Currently Global Crossings is handling our audio conference bridging services.  The cost with the new Global Conferencing will be $0.023 per minute per participant which is much better than the between $.09 and .12 a minute we were paying with Time Warner Telecommunications.

 

If you are in need of a Polycom tabletop conference phone for your audio conference or webinar and are located on the Medical Center campus, you may rent one from the Information Services Telecommunications Department by contacting Catrina Renegar at 336-716-9292.  If you are interested in purchasing a Polycom tabletop conference phone for your conference room you may contact Darryl Sterner or Joel Fletcher.   

 

Webinar

A webinar is sometimes referred to as an on-line workshop and refers to an on-line service that allows conferencing events to be shared with remote locations.  This service allows for real-time communication from the sender (presenter) to many receivers (participants).  Webinar technology allows the presenter to show all types of computer graphics, video clips, and text documents with all participants.  This model is a one-to-many model since a webinar can have hundreds of participants all viewing the same presentation simultaneously over the Internet.  A webinar is a “hosted” service which means that pay a subscription each month for ability to host a webinar and invite participants.  WebEx, GoToMeeting, and Adobe Connect are examples of webinar service providers.  Most webinar service providers require the use of a telephone line to hear the presenter. The participant would connect the URL address send to them by the host to view the presentation then follow the instructions in the email on how to join on the telephone to hear the presenter. Webinars have evolved over recent years and many now support high definition video so you can now see the presenter and the presentation at the same time throughout the meeting.   

 

The Medical Center Information Services department does not officially endorse or support WebEx, GoToMeeting, or Adobe Connect although everyone is permitted to subscribe to these webinar services as they feel necessary.  Information Services is planning on the deployment of Microsoft Lync sometime late Spring which offers many of the same features at WebEx, GoToMeeting, and AdobeConnect.  Microsoft Lync would be available to all Medical Center employees.  If you need assistance with locating a conference room to participate in a webinar contact Darryl Sterner or Joel Fletcher.

 

Webcast

A webcast is a media presentation or audio distributed over IP networks using streaming media technology such as Adobe Flash or Windows Media from a single content source to many simultaneous viewers.  A webcast can be distributed live or as a video-on-demand program.  A webcast is generally not interactive.  Here in the Medical Center our CEO town hall meetings are distributed to employees as a live webcast and then made available later as a video-on-demand program so employees can watch it at their convenience.  Currently, Babcock is only location from which a webcast can originate from.  If you have a training video, product use video, or safety video that you would like to have made available as video-on-demand program please contact Darryl Sterner or Joel Fletcher.
