Video Team Hardware

Work In Progress

Proposed shopping list / kit list per room

Audio

2x Headset Radio Mic
2x Handheld Radio Mic
2x Mic Stands (Good for getting people to queue up to ask questions - use with handheld mics)
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
  • Possible Open Hardware project?

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

  • Requires minimum 8 XLR input channels
  • Requires main and aux outputs (I am going to assume XLR for both of these - for this shopping list)
  • * main XLR goes to Main Camera
  • * Aux Send goes to house PA (preferably as a slide fader)

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

Opsis: Presentation capture

* Opsis FPGA Video to USB * 1U case * ?MinnowBoard Turbot (Micro PC)

* Small SSD

Tasks:

  1. Confirm that the Turbot is a suitable PC system
  2. Update to fanless PSU
  3. mount into 1U case with the following connection seup
    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 confidance 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

      • Powersupply to ?MinnowBoard (& SSD)

      • Powersupply 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 sequance 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 mixor 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 quiate fans)
  • 4U Rack Case
