YSTV broadcasts across campus by using compserv's network, with streams terminating at individual 'drain' computers, which display the stream full screen.

Drains

Basically, they're PC's running either a custom flash player, or full screen google chrome with a few settings tweaked. Stick internet in one side, and composite or VGA out the other.

Rediffusion

Rediffuison is the antiquated closed circuit broadcast network that was installed in the university in the 60s. YSTV and URY used this network from the early 90s until around 2008 when it was "replaced" by an IP-Based system.

There aren't many ways of sending video via cable accessible to YSTV anymore. Although we still technically own the broadcast network. The university estates dept have done a pretty good job of hiding what is left of the Reddiff / ystv system, although there are still a few points where you can still witness the sh**ness of the mammoth network. As reddiffusion's signal quality is "rubbish" and the system was too much to manage, it has been mainly abandoned. Should you actually want too use it in future, be warned: the bandwidth in some bits of connecting hardware/electrics is really really small, really covered in asbestos, and really painful to get to - estates ain't gonna let you in those asbestos filled vent rooms and covered walkways....
