'''Main Stage:'''

*  Sky Cam (V139):
**  Trail cable out of V120, across balcony (NB the boards which make up the floor of the balcony may accommodate the BNC nicely, alternatively weave it in the rails.  Loop cable around window frame, secure to tripod and plug into camera.  Camera running off mains power from somewhere in V139, may require a medium length extension lead.

*  Howard (marquee roof):
**  BNC from howard, taped to howard and secured to frame, not dangling from socket.  This trails down whichever side of the frame is most convenient, and probably goes into a video over cat5e box.  Also needs power over 4-pin XLR, and control over cat5 to go all the way to the roof.  Preferably check Howard works before they finish putting things on the roof, so we can tell them to take it down to be fixed, or just to adjust something on it, plug something back in etc.  At the very least if it doesn't work we can know not to use it or lay cable for it.
Signal over BNC all the way to V120

* Three HD Sonys
**  Umbilical to each camera, secured to the camera/tripod to put as little strain on extension and socket as possible, possibly also have s-vid bodge(s) and cable ties or tape nearby in case one of the sockets goes faulty.  Video from probably all three into a video over cat5 box.

Broadcast signal along cat5 '''TO''' stage to feed preview monitors for camera ops.


'''Balcony'''

*  Two xlrs, one for the omnidirectional caged mic as main stage sound backup, the other for the rifle mic or cardioid which the presenter uses.

*  Comms for presenter (the camera op should know what they're doing, and can receive cues from the V120 window).

*  Non-Firewire Canon
**  BNC for camera, from V120, to balcony railings, into breakout cable and Camera.


'''Indoor Stage'''

Cat5 doing either 3 cameras from the hall to the control room.  BNC should go on the wide shot camera (more reliable than over cat5, also makes the most sense in terms of where cables go).  Have a BNC from each of the three cameras near the stage running to the cat5 box under the stage, cat5 cable running to back of hall and out of window.  Reduce chance of damage to cable by taping it close the the wall, standard cable guards etc.
Hopefully no alterations will need to be made, if they are someone will have to crawl under the stage.

Mains to power cameras, I haven't specifically asked for this but there shouldn't be a shortage of power, given all the mains sockets on the walls anyway.

All indoor stage video cables to V12'''''2'''''

Also will need a BNC cable from V120 into V122 for VT PC's output, if there's no equivalent computer dedicated to the roll in V122.


'''CAT5 ADAPTORS'''

Will have the powered one in the hall, and the passive one on the main stage.  This will of course only work if the passive one can send a decent signal all the way to V120 from the main stage.  I think the distances to the two stages are about equal anyway.
*  Advantages:
**  Powered one caters for three signals, we have three cameras on indoor stage, one cat5 to back of hall and out of window towards V122 (avoids having three bncs running across the hall, saves cable length, simplifies run, fewer potential fault points etc.).
**  Main Stage is more important, the passive sender sends one signal on each pair, they're completely isolated as far as I (Malcolm) know.  If one pair develops a problem we still have three good camera signals being sent along the cat5.
**  Is bidirectional, the monitors at the main stage will receive signal, uses one of the less-reliable and lower-quality cat5 pairs rather than a BNC for low-priority monitors.

*  Disadvantages
**  May not be powerful enough to send signal, would prefer signal from main stage to be good.


'''Comms'''

Mostly still to write down.


'''Main Stage Monitors'''  

Broadcast out (or maybe pre graphics) along one of the cat5 pairs via the passive sender, to the main stage receiver (the sender and receiver are identical) along a BNC to a monitor, from that monitor's '''loop through''' to the small homemade test monitor.  Need 12v supply and IEC lead.


'''URY'''

Three Good XLRs from URY (stereo balanced main stage and mono balanced indoor stage).  One BNC cable going to them for their preview of YSTV.  These leads will follow the route out of the SCR, over the JCR roof, into V122 via a window, out of V122 via a window (supports cable), into V120.

Obviously the Indoor stage mono audio won't need to go to V120, so will go into Max in V122.
