Digital Cinema Initiatives - Image and Audio Capability Overview

Image and Audio Capability Overview

  • 2D Image:
    • 2048x1080 (2K) at 24 frame/s or 48 frame/s, or 4096x2160 (4K) at 24 frame/s
      • In 2K, for Scope (2.39:1) presentation 2048x858 pixels of the imager is used
      • In 2K, for Flat (1.85:1) presentation 1998x1080 pixels of the imager is used
      • In 4K, for Scope (2.39:1) presentation 4096x1716 pixels of the imager is used
      • In 4K, for Flat (1.85:1) presentation 3996x2160 pixels of the imager is used
    • 12 bits per color component (36 bits per pixel) via dual HD-SDI (encrypted)
      • 10 bits only permitted for 2K at 48 frame/s
    • CIE XYZ color space
    • TIFF 6.0 container format (one file per frame)
    • JPEG 2000 compression
      • from 0 to 5 or from 1 to 6 wavelet decomposition levels for 2K or 4K resolutions, respectively
      • Compression rate of 4.71 bits/pixel (2K @ 24 frame/s), 2.35 bits/pixel (2K @ 48 frame/s), 1.17 bits/pixel (4K @ 24 frame/s)
    • 250 Mbit/s maximum image bit rate
  • Stereoscopic 3D Image:
    • 2048x1080 (2K) at 48 frame/s - 24 frame/s per eye (4096x2160 4K not supported)
      • In 2K, for Scope (2.39:1) presentation 2048x858 pixels of the imager is used
      • In 2K, for Flat (1.85:1) presentation 1998x1080 pixels of the imager is used
      • Optionally, in the HD-SDI link only: 10 bit color, YCbCr 4:2:2, each eye in separate stream
  • Audio:
    • 24 bits per sample, 48 kHz or 96 kHz
    • Up to 16 channels
    • WAV container, uncompressed PCM

Famous quotes containing the words image and and/or image:

    “We have no participation in Being, because all human nature is ever midway between being born and dying, giving off only a vague image and shadow of itself, and a weak and uncertain opinion. And if you chance to fix your thoughts on trying to grasp its essence, it would be neither more nor less than if your tried to clutch water.”
    —Michel de Montaigne (1533–1592)

    “As every pool reflects the image of the sun, so every thought and thing restores us an image and creature of the supreme Good. The universe is perforated by a million channels for his activity. All things mount and mount.”
    —Ralph Waldo Emerson (1803–1882)
