Videoconferencing - Interactive Television (ITV) 
General videoconferencing information:Videoconferencing is relatively similar to a telephone call, but it also includes a video signal. Cameras and microphones in a classroom or conference room capture both video and audio. Then, a device called a codec compresses this input into data and sends it via dedicated circuits, Internet or wireless to another location, sometimes thousands of miles away! People at both locations can collaborate, almost as if they were together in person.
How is videoconferencing being used at SFA?
Videoconferencing (ITV) is not new to SFA, but the technology related to it is constantly advancing. Stephen F. Austin State University utilizes several protocols to deliver videoconferencing for instructional and administrative needs. Our multi-classroom videoconference systems offer a wide range of connectivity options. Most of our on-campus systems are H.323 compliant, which means they can operate using a standard Ethernet connection in a classroom or office. By using these units, we can have a portable system set up quickly and harness the flexibility of our campus network, without the need for costly, dedicated circuit connections that are only available in a few select classrooms. We can establish connections with other high-bandwidth partners who also have IP-based systems to deliver compressed video over the Internet. Another benefit is being able to take advantage of SFA's Internet 2 connectivity when videoconferencing to other members or pier networks. The Northeast Texas Network Consortium (NETnet), provides high-quality connectivity to SFA and other affiliated institutions throughout East Texas. Through this consortium, SFA also has access to ISDN-based connectivity for placing toll calls to virtually anywhere.How can you use it?
Videoconferencing can be used for various types of meetings and special events where people are not able to physically meet. It is ideal for guest speakers and lecturettes. It may also be used to reach students at distant locations, who otherwise would not be able to attend classes at SFA. If you have questions about how you can utilize ITV to help accomplish your mission, please contact Randy Watson.Does OIT offer Training?
OIT offers a comprehensive series of workshops in our Certified ITV Instructor Workshop Series. These worshops were designed to help faculty or administrative staff comfortably switch from a traditional face-to-face class or conference room venue, to an ITV setting. To see when this series is offered, please visit our workshop registration page.
What's coming with "next-generation" videoconferencing technology?
Connectivity will continue to get better and better. SFA has been and will continue to be involved in the development of the Lonestar Education and Research Network (LEARN), which will inter-connect many instuitutions around the state at very high band rates by utilizing dark fiber.
High definition will also begin to filter into the world of videoconferencing. As band rates improve, the doors also open for better connection rates, thus allowing the 1280 x 720 pixel resolution (HDTV) signals to be transmitted. Many new products are coming out this year and we will be evaluating them for possible test implementation in select classrooms for 2007.
