... TV standard independent Incredible blue stretch Optional YC-processing. GENERAL DESCRIPTION The TDA9171 is a transparent analog video processor with YUV input and output interfaces. The luminance transfer is controlled in a non-linear way by the distribution discrete histogram sections, of the luminance values measured in a picture result, the ...

... The miscount detector disables measurements until it detects changing parts. Additionally, luminance values close to full scale (or white) do not contribute as well in order to maintain the absolute light output. This procedure is allowed because the eye is less sensitive to detail in white. 4 Preliminary specification TDA9171 20 BLM 19 UOUT 18 VOUT V ref ...

... U and V signals are also processed for saturation compensation. By convention U and V signals must be supplied to the TDA9171. The U and V input signals are clamped during the logic HIGH period of CLP, defined by the sandcastle reference. In YC-applications just one colour difference channel is required for processing the chroma signal ...

... J1 and J2 can be used to select the appropriate luminance amplitude mode. Potentiometers BLG, BLM and NLC can be used to apply proper blue stretch and non-linear amplifier control voltages. The TDA9171 is also prepared for YC-processing. A typical application diagram is shown in Fig.9. Jumpers J1 and J2 can be used to select the appropriate luminance amplitude mode. Potentiometer NLC can be used to apply the proper non-linear amplifier control voltage ...
