    NTSC only non-linear editing system
  • broadcast quality, tapeless nonlinear editing system for the Video Toaster and Video Toaster 4000
  • requirements:
    • Video Toaster with v4.1 software
    • a SCSI 2 drive for Lightwave recording
    • three SCSI 2 drives for A/B roll editing - two for video, one for audio
    • input from video tapes must be time base corrected
  • compresses and plays back video in realtime
  • true broadcast quality - 60 fields per second, full overscan 752×480
  • internally works with D2 data - no D2 / composite transcoding
  • proprietary coporession method: Video Toaster Adaptive Statistical Coding (VTASC):
    • relies on limiting the video signal (i.e. dropping to Beta SP quality) instead of lowering picture quality as do JPEG, MPEG, WaveLet
    • no visible pixelization, artifacts show as video "noise" instead of jpeg "blockiness"
    • by using faster drives, lossless D2 quality can be achieved
  • three SCSI buses (two for video, one for audio), each bus can handle 7 SCSI drives (21 total)
  • two serial ports to control serial-capable VTRs
  • the SCSI and serial ports can be routed outside of the computer with the so called Octopus cable
  • video:
    • video input to the Flyer is provided via the connecting internal ribbon cable from the Toaster, as is video output
    • 14.3 MHz sampling rate
    • 8 bit quantizing
    • 8 MB buffer
  • audio recorder / mixer:
    • ADSP2115
    • digital inputs
      • video disk A and B, left and right
      • audio disk A and B, left and right
    • analog, unbalanced left and right RCA inputs and outputs on the card's backplane
    • 64 kB memory
    • 20 MHz clock rate
    • 16 bit sampling at 44.1 kHz
    • 64x oversampling ratio A/D converter
