Video Team Hardware

Work In Progress

Kit list per talk room

Audio

2x Headset Radio Mic
2x Hand-held Radio Mic (omnidirectional, because people hold them the wrong way)
2x Mic Stands (Good for getting people to queue up to ask questions - use with hand-held mics) (we have 1)
4x 2m XLR cable (mic receiver to snake)

  • Radio Mics need to be licence free in all 3 ITU regions
  • We need to be able to change frequency to avoid interference with other users
  • Radio Mics are a minefield regarding licence and available frequencies we can use, the licence exempt spectrum (not 2.4GHz/5GHz) is not wide enough and does not permit more than 2 mics to be used.
  • We should purchase only 1 room worth of kit NOW and re-examine later...

Tasks:

  1. Identify suitable radio mic systems (farm off to QAV)

2x Ambient Mic (pick up audience chatter / shout out questions)
2x Microphone stand (for ambient mics)
2x 20m XLR cable (to run from ambient mic to desk)

1x 5m 3.5mm stereo Jack to 2x 1/4" mono jacks (PC Audio to DI Box)
1x stereo DI box (2x 1/4" socket In to 2x XLR-M) active / phantom powered (PC audio)
2x 2m XLR cable (DI to snake)

1x 25m Mic 'snake' reel - 6 in 2 out

1x 8 channel mixing desk

2x 5m XLR cable mixing desk to Main camera
2x 20m XLR cable mixing desk to PA (potentially via snake)

1x Balanced to unbalanced stereo balun transformer (XLR-F in to 1/4" Socket Out)
2x 2m 1/4" Mono Jack to Jack
1x 2m 1/4" Mono Jack to stereo 3.5mm jack
1x 2m 1/4" Mono Jack to RCA phono plug
1x 3.5mm Socket to 1/4" mono jack adapter

Camera

  • Sony PXW-X70 (6x purchased)

  • Camera cable. SDI cable on a reusable reel something like:

http://www.ebay.co.uk/itm/3x-CABLE-DRUM-ROLLER-REEL-HEAVY-DUTY-SPOOL-STEEL-FRAME-HANDLE-SET-EMPTY-BLACK-/282208316457?hash=item41b4ed2c29:g:pIYAAOSw4shX9P-x

  • Possibly run Ethernet alongside?
  • Cable needs to be very flexible and suitable for 'hard' re-use (i.e. multiple install / un-install, across floors etc)

Opsis: Presentation capture

Tasks:

  1. Confirm that the Turbot is a suitable PC system Done - works fine
  2. Update to fanless PSU
  3. mount into 1U case with the following connection setup
    1. Connection to outside world
      1. Common
        • IEC power
        • Power Switch
        • LED from nRST of OPSIS
      2. Opsis
        • HDMI IN (from Presentation laptop)
        • HDMI Out (to Projector)
        • HDMI Out (to confidence screen)
        • Reset (+remote from minno board)

      3. ?MinnowBoard

        • Ethernet (to Mixer PC)
        • USB sockets 1 (or 2 if available)
        • Reset

        • GPIO out from ?MinnowBoard to LED

    2. Connections internally
      • Power switch to power supply

      • Power supply to ?MinnowBoard (& SSD)

      • Power supply to Opsis VIA GPIO Controlled Relay from ?MinnowBoard

      • HDMI Out from ?MinnowBoard to Opsis

      • JTAG from ?MinnowBoard to Opsis

      • GPIO out from ?MinnowBoard to relay to power sequence Opsis

      • GPIO out from ?MinnowBoard to relay to switch P18 / K2 (DPDT)

Video Mix PC

  • PC Able to host video mixing for 1 room
  • For single room events (i.e. a miniconf) this is the only PC needed on site
  • Vocto Mix video mixer software
  • 2x Black Magic SDI Capture Cards
  • 2x NIC (1GBit/s)
  • current generation i7
  • 16 GB RAM
  • 120GB SSD - System
  • 2 x 3TB HDD (Mirrored)
  • Silent (at least very quite fans)
  • 4U Rack Case NOT to be shipped for miniconf (local miniconf team can supply this!) We ship this as a single case for debconf (n x Talkrooms + 1)
  • Keyboard
  • Mouse
  • Monitor

Kit list VideoTeam Operations Room

Video Master PC

  • Video Master PC is used during debconf only. It is responsible for:
  • local backup
  • local ICEcast Master
  • local vypar
  • Gate way for Talk rooms
  • Same HW as Talk room PC but with 4x3TB spinning disks and 32GB RAM
  • Packet Switch

Flight Case Builds

Front of House Rack

Build a 19" Flight case containing Radio mic receiver, Storage draw, Opsis (and Support PC - Turbot), Packet Switch, Power.

To the wall of a 4U tray attach IEC mains inlet, as well as 4xBNC antenna and 2x45 bulkhead connectors. To the floor of the 4U tray attach the the mains power block. European plug / sockets have been selected because this matches most of our existing wall wart power supplies! The 4 U tray creates the rear wall of the flight case, whilst the equipment (and draws populate the front) To the packet switch should also be attached to the floor of the tray.

Use RJ45 patch cables to connect the packet switch to the C&C port of the Mic receiver, both ethernet ports on the Opsis 'box' (i.e. Opssis and Turbot), and the 2 bulkhead ports of the tray Also use BNC patch cables to connect the 4 antenna points on the mic receive to the inside if the BNC bulkhead connectors.

Attach the DI box to the tray. Attach stereo 3.5mm out from the Milkymist IO board (Opsis box) to the input on the DI box. Attach the 6 XLR Male connectors to the wall of the tray. Take 4 to the radio mic receivers and the remaining two to the DI box.
