NXP Semiconductors TDA9178
The TDA9178 is a transparent analog video processor with YUV input and output interfaces. It offers three main functions: luminance vector processing, colour vector processing and spectral processing. TDA9178 The adaptive black stretch function of the TDA9178 offers the possibility of having a larger ‘weight’ for the black parts of the video signal; the white stretch function offers an additional overall gain for increased light production.| Part No. | TDA9178 |

GENERAL DESCRIPTION
Beside these three main functions, there are some additional functions. In the luminance vector processor, the luminance transfer function is controlled in a non-linear way by the distribution, in 5 discrete histogram sections, of the luminance values measured in a picture.
