 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 mammoth network. Likewise, there are a handful of known continuous cable runs around campus:
+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. Likewise, there are a handful of known continuous cable runs around campus:
-====known cable end locations====
-* G/046 techie room ceiling: if by any random chance YSTV is not located in G046 anymore, G046 is here: ##location description##. In the back right corner of the tech room (the awkward tall L shaped cupboard space) Two lines of Reddiff Core (really thick twisted pair multicore) appear.
-** One line to derwent
-** One line to unkown location.
-* Derwent JCR/common-room: far corner from the entrance, look for the Really big S-type coax ports.
-* Derwent library: just upstairs of the JCR. Port known to exist, but location unknown. (used to broadcast elections from here - pre student union run "courtyard" opened).
-* Cookies snack bar: in biology, outside BB/002 opposite the giant ceiling space. Coils seen week 9,autumn,2010.
-====Known good runs of cable====
-* G/046 windows: This, until 2007/8 was the main exit for the network. It consists of:
-** 2 satellite COAX's to some (probably rusty) dishes ontop of G/169 (computer room upstairs). These used to carry the sky (analogue!), Astra etc feeds for simulcasting onto the campus network (we used to have 1 TV licence to cover all campus communal areas!).
-** 1 Analogue feed for UHF reception for simulcasting  - the nearest broadcast tower is at Elmly Moor, somewhere off in the Yorkshire Dales. We even used to have the phone number of the duty technician!
-** 2x campus COAX, known herein as "Physics Video send & return".
-** 2x campus XLR, for Physics send and return audio.
-*** The '''physics send & returns''' go out the window, over the roofs, drape onto the covered walkways, turn left at YUSU (student centre / Daww Suu), along towards physics, and enter via various methods into the PX/002 loft space - YSTV used to be based in the chair store, so when forced out, new cables were just chained to physics.
-*** One coax enters through that awkward hole halfway up the wall, and the other thee cables go past the wall, get sealed in with the doors, do a U-turn, then the disappear into the loft space.
-** Coax and XLR to the photobooth outside James JCR. There used to be a TV there, before passports became popular.
-* Vanburgh TV distro to JCR & Bar TV's.
-** At Vanburgh vending machines up high on the back wall, is a coil of cables: via a series of mini-distro's and junction boxes, the cables can be used to send video IN ONE DIRECTION ONLY - there is thought to be something active hidden behind those ceiling tiles. Sound is just unbalanced phono to a pattress box near the JCR entrance, being just cable, there are no direction oddities.
