Text 5. Satellite uplink upgrade

Satellite uplink upgrade – TNS operates a satellite uplink service that allows live or pre-recorded video to be uplinked to satellites and made available to anyone that has authorization and access to a downlink facility.  The most common uses for this service are athletic events that are broadcast from campus, Athletic Department coaches’ shows, new conferences and promotions, and interviews with campus experts for major broadcast and cable TV feeds. There is also a small amount of use by the public at large.

Much of the current equipment and technology is about 20 years old and is no longer supported by the manufacturers. Another significant issue, which surfaced sooner than expected, is the requirement by the broadcasters for football and basketball games for Dual Thread High Definition (HD) video for many games next season. To support this, we require a full upgrade of the entire system.

Since our funding model relies on this “game revenue” to break even, this has forced a technology and spending decision upon us.  TNS is investigating alternatives for supporting this service.

Video conferencing and streaming service expansion – TNS is engaged in enhancing video conferencing and video streaming services to satisfy a broadening customer base.  These services have been supported for several years within TNS, under a lesser defined model.  Relatively recent changes in technology and increased demand for these services on campus is cause for TNS to review our technical, operations, and support capabilities.

The most common form of display screen is the CRT. A CRT, for cathode-Ray tubes is a vacuum tube used as a display terminal. This same kind of technology is found not only in the screens of desktop computers but also in television sefs and flight-information monitors in airports.

Images are represented on the screen by individual  dots called pixels. A pixel, for “picture element”, is the smallest unit on the screen that can be turned on and off or made different shades. A stream of bits defining the image is sent from the computer to the CRT's electrongun, where the coater with phosphor, it lights up selected pixels to generate an image on the screen.
