Tarantula
Tarantula is YSTV's new scheduling and automation system, to control the Video Server and output matrix, enabling the Scheduling Managers to queue up shows to play on the web stream throughout the day, like a "real" TV channel.
Check out the Trac pages at https://ystvdev.york.ac.uk/trac/Tarantula for status on the project and access to the source code to get involved.
As of Summer 2012, Sam Nicholson is attempted to resurrect and complete Tarantula so that YSTV might have a scheduling system again.
