Description

  The TDA9170 is a transparent analog video processorwith a YUV interface. It offers three main luminanceprocessing functions any combination of which can beselected.
  The luminance transfer is controlled in a non-linearmanner by the distribution (in 5 discrete histogramsections) of the luminance values measured in a picture.As a result, the contrast ratio of the most important parts ofthe picture will be improved.
  The TDA9170 is a transparent analog video processor Black restoration is available in the event of a set-up in the luminance signal. A variable gamma function, after the histogram conversion, offers the possibility of excellent brightness control.The luminance transfer is controlled in a non-linearo maintain a proper colour reproduction, the saturation o the U and V colour difference signals are controlled as a function of the actual non-linearity in the luminance channel.
