caption_attribution_description: English: A bank of Sony RCPs (remote control panels), used for racking TV studio cameras.
context_page_description: The camera control unit is typically part of a live television broadcast chain. It is responsible for powering the professional video camera, handling signals sent over the camera cable to and from the camera, and can be used to control various camera parameters remotely.
context_section_description: A CCU is often used in conjunction with a remote control panel (RCP), a waveform monitor and a vectorscope to rack and match many cameras together remotely.
  Common adjustable parameters include:
  Iris (see aperture)
  Color temperature filters
  Neutral density filters
  Shutter speed
  Saturation
  Master gain
  Master black (pedestal)
  Black level trim (for red, green and blue components)
  Gain trim (for red, green and blue components)
  In addition to these, there are usually options internally generating a test card for testing, return feeds or talkback. For more complex productions, preset scene files can be recalled to quickly change the settings of the camera on the fly.
