  • Bi-directional Transcoding PAL (B, G, I), PAL N.
  • Five-line high performance adaptive comb filter. Bandwidth 6 MHz.
  • 10 bit precision, 4:2:2 processing and conversion, with oversampling.
  • Differential composite video input.
  • Four composite video outputs.
  • User friendly control panel with graphic lighted display, keyboard, and extensive selection and enhancement facilities.
  • Luma gain, chroma gain and black level controls.
  • Horizontal and vertical (aperture correction) enhancers.
  • Selectable input filter.
  • Selectable luminance bandwidth.
  • Switchable bypass in the vertical interval. Allows the pass of the “closed-caption” signals.
  • Selection of lock reference: output subcarrier locked to horizontal, to the input subcarrier or to internal reference.
  • Selection of output signal in the event of input signal loss or error.
  • Programmable test signal patterns
  • Dual redundant power supply and monitor of power supplies (FD option).
  • Specially recommended as PAL B to PAL N transcoder  for broadcasting signals.
