DATN
Digital Academic Television Network
The Digital Academic Television Network (DATN, pronounced "Dayton") is the digital replacement for the University of Wisconsin's Academic Television Network (ATN).
History
ATN previously carried a selection of local television channels,
instructional and specialty content from various campus entities,
and satellite programming over a traditional coaxial cable network.
ATN was essentially a full cable TV network operated by DoIT. However,
ATN has reached the end of its life and is no longer maintained by
the university.
When it came time to replace ATN, it was determined that the replacement should be more flexible, able to deliver live content via the network in addition to on-demand content, and enable origination of content without costly investments in video equipment. The university's new, high-speed 21st Century Network provides the performance and capabilities necessary to accomodate the needs of this type of high-bandwidth content delivery.
Going Digital
DoIT examined several options for delivering live content digitally
based on open standards, such as MPEG-4
and AAC, in an accessible
fashion (with novel implementation of services such as closed captioning).
A solution based on Apple QuickTime
technology was selected. The first phase of DATN is rebroadcasting
the same 11 local television channels previously offered by ATN with
QuickTime, at a reasonable quality to reach the widest possible range
of clients. Higher quality broadcasts are planned in the future.
